Precision T7400, Which verison of Windows 7?

This question has suggested answer(s)



I writing about a Precision T7400 for a customer of mine.  It has two Intel Quad Core Xeon X5482 Processors at 3.20 GHz, and I think it has 8 GB of RAM, but maybe only 4 GB.  The Intel Products web site says that this CPU has a 64-bit Instruction Set, and under Advanced Technologies, it says Intel® 64, so I figure that makes it a 64-bit Processor.

I'm writing to learn which version of Windows 7 to use; 64-bit or 32-bit.  Just checking.

It has an nVidia Quatro FX3700 512MB Video Card, and has an SAS-6 160GB SATA Hard Drive, but this computer has never performed well.  The computer has Windows XP Pro (32-bit) with SP3 on it now (we opted to downgrade from Vista Business), but for all of this computing power, it's horribly slow for a computer of this caliber.  His Secretary has a Precision T5400 that was bought at the same time, with a single Xeon 2.0 GHz Quad Core CPU, that runs circles around his.

I recommended this Precision T7400 to him because my Ex bought one on my recommendation about 1 month earlier, with only a single Xeon Quad Core 3.20 GHZ CPU and the SAS-6 Hard Drive, and it really screamed when it was new (for about the first 6 months), so I thought that with two Xeon CPUs and the 10,000 RPM Hard Drive, it would really perform, but like I said, it's horribly slow (and so is my Ex's, by the way).  His computer takes 12 minutes to boot and fully load everything from Power Off.  From Power Off, it takes the SAS-6 boot-time configuration utility 3 whole minutes by itself to load before Windows ever starts to boot.  12 minutes is a long time for a computer of this caliber. 

I worked on it a month ago and got it down to 6 minutes at Power On from 20, but a few days ago I tried to make it faster again, and after I got the latest BIOS, some new Drivers, some Windows Updates (including IE8) that he had ignored, and ran some Optimization programs and Registry Cleaners, it's up to 12 minutes now.  Granted, there are a lot of programs installed, as it's a business computer, but this computer should be able to handle Anything!!!  So I'm thinking about taking out the SAS-6 Hard Drive and putting in a regular SATA 7200 RPM Hard Drive to see if that will help the performance, and while I'm at it, I want to upgrade to Windows 7.  I'm quite sure that a fresh installation of Windows will help, and Windows 7 is pretty efficient.  And I'm fairly sure that replacing that SAS-6 Hard Drive will help.  Any thoughts on this?  I'd appreciate your input.

So back to the original question...  32-bit or 64-bit Windows 7?  He has many new programs, like Office 2010, and even though they're all 32-bit, I think he'll be OK with his Software Library if Windows 7 64-bit is the way to go, but we'll have to check with some of his business partners to see if the programs they supply are Windows 7 64-bit compatible.  And we'll have to check with QuickBooks.  Maybe Windows XP Mode will help with those programs.  I'm thinking about Windows 7 Ultimate.  This computer was purchased in May of 2008, so I don't think there'll be any issues with Windows 7 compatibility, and I have Driver Genius Pro, in case Dell doesn't have Windows 7 Drivers.  However, if we decide to stick with Windows 7 32-bit, for compatibility with some of his business-partner-supplied programs, do you think there'll be much of a performance loss as compared to 64-bit?  And if we go with Windows 7 64-bit, does Windows XP Mode work with that, and does it create any performance losses? 

Just trying to cover all the bases, and finally get some performance from this machine.  I'm hoping you'll address all of the questions.

Thanks in advance,

  • I have the same computer with duall 3.20 cpu's, gtx 660ti & quandro 5800 that I have dedicated to phys X only.  My boot drive is a sony ssd, operating system is windows ultimate, 32 gigabytes of ram and about 3 terrabytes of hd space.  My boot time is around 30 seconds at the most.  The speeds that you are talking about are VERY slow.  Pays to do a little research.  Computer is awesome although a little ancient. Nevertheless I enjoy mine everyday.  Good luck and I hope that you can see that yours can accommodate better hardware and software.

  • Use the 64-bit version of Windows.  32-bit can only address 4GB of RAM (and even less - as little as 3GB - will actually be usable by Windows), so if you choose 32-bit and have 8GB of RAM, you/he will be losing half your/his RAM.  Nearly all 32-bit programs will run just fine in Windows 7x64.  XP Mode can help with other odds and ends that don't work (Windows 7 must be Professional or higher, and there is some initial lag on startup of XP Mode programs, and should be run on a separate disk for best performance), but I think you'll find most software will run fine in Windows 7, unless it is really old.  QB 2009 and older will not work on Windows 7, but it has nothing to do with 32-bit vs. 64-bit.

    12 minutes is long for a computer of any caliber.  My old XPS G5 takes about a minute to power on and load everything.  I have an Exchange server that takes 8-10 minutes to boot up and load everything.  Your system has something wrong with it.  A clean install is a good place to start, but once you start reloading everything back on it, watch for startup programs and services that are installed with the various programs.  If your SAS 6 is taking that long to initialize and spin up the drive, then try removing/disabling it, as you have suggested.  I have a server with the server version of the SAS 6 that takes less than 3 minutes to boot.



  • I have a T7400 running 7 Ultimate on a T7400, 64 bit.  It has two QUAD XEON core processors (2 GHZ), 16 GBytes of ram, a SAS disk (600 GBytes 15,000 rpm), and a NVIDIA FXvideo card (512 MBytes ram).  Boot time is around a minute, maybe less.  I don't usually check it, also I never turn it off.  Performance is a different issue, Photoshop, Maya, 3ds MAX, and most SQL server love memory, the more the better.  Other applications could care less.  

  • Generally the 64 bit version of Windows 7 would work better on such a machine especially if it has 8 GB...

    For Microsoft Office you can install the 64 bit version also however some third party programs which have addins won't work properly such as Mendeley Desktop or MathType (64 bit Mathtype beta is available). Since you might use such programs stay with the 32 bit Microsoft Office (it works fine on 64 bit Windows 7).

    Follow my wiki A Clean Install of Windows 7 use the 64 bit version. For best results ensure the Service Pack is included on the installation media or installed immediately after installing Windows 7. With respect to the drivers, use the Vista 64 bit drivers with Windows 7 64 bit but for the Intel Chipset get instead R302424.exe, (get the "Dell Device" in addition to this). For the video get it right from nVidea here.

    XP Mode works with 7 Professional, Ultimate, Enterprise (32 bit or 64 bit). It actually works better on the 64 bit version of Windows 7 as you can adjust the settings so the virtual machine can use 3.24 GB of RAM. If you have 8 GB of RAM or 16 GB of RAM in total the virtual machine will perform much better. This you will have to download after install Windows 7 here. Alternatively you can use an XP license with VirtualBox which is slightly better than XP Mode in some aspects.

    Now for programs, what security programs are you putting on these machines?

    What registry cleaning, any speedupmypc programs or similar? In general registry cleaners/system optimisation programs screw up the performance of the system. They are less than worthless. CCleaner and Defraggler both free by Piriform are the best ones to use for system optimisation and haven't broke anything for me. Download links to both and variety of other free programs are in my recommended software wiki.

  • Thanks guys, all 3 of you.  Lots of good info between you.

    Natakuc4 asked what Registry Cleaning and SpeedUpMyPC programs I am using.  I've been using CCleaner for years without problems.  I recently found that RegZooka was rated the highest among Paid Registry Cleaners, so I started using it without issues, too.  It finds a whole lot more than CCleaner.  It makes a backup of the Registry before making changes, and has a Registry Defragmenter, too.  I've been using it on both my own and my customer's PCs without issues.  I've also used AvanQuest Fix-it Pro and iolo System Mechanic on my own PC with good results, but these are paid programs for my own computer, so I wanted something to find more system errors than CCleaner for customer's computers.  I went to Cnet's and researched the available programs there.

    I found the three top-rated programs in the categories of Diagnostic Software, and Maintenance & Optimization, being

    #1 in Diagnostic Software - Advanced SystemCare v5.2.0.223 (Free)
    #2 in Diagnostic Software was a Trial Version of a Paid Program
    #3 in Diagnostic Software - Toolwiz Care v1.0.0.1500 (Free), and
    #4 in Diagnostic Software - Wise Disk Cleaner v7.13 (Free),
    #1 in Maintenance & Optimization - Crap Cleaner [already had this]
    #2 in Maintenance & Optimization was a Trial Version of a Paid Program
    #3 in Maintenance & Optimization - Wise Registry Cleaner v6.21 (Free), and
    #4 in Maintenance & Optimization - WinUtilities v10.44 (Free)

    I installed and ran Advanced SystemCare v5.2.0.223 on the T7400, and it messed up the SAS Drive - got a BSOD, so I rebooted into Safe Mode and uninstalled it.  Then I installed Wise Disk Cleaner v7.13 and ran it without issue, but I stopped there, as it was very late.

    For security programs, I use AVG 2012 Free for AntiVirus, and STOPzilla for AntiSpyware.  I'm aware that avast! is higher rated, but it tends to have a Paranoid behavior that would confuse many people, so I stick with AVG on my customer's PCs.  However, I do use avast! on my own.  I've been using STOPzilla since 2006, when I found it.  I used to get infected computers in the shop, and I'd run 10-15 different AntiMalware programs on them, hoping that what one missed, another would find.  I had a routine of installing them in a particular order, and when I found STOPzilla, I would install it last, and it always found things that the others missed.  So one day, I installed it first, and then ran all the others, and none of them found anything after STOPzilla had done it's thing.  I did that for a while, with the same results, so that told me that STOPzilla was the best - and it still is. 

    I still install SpyBot Search and Destroy v1.6.2, because there are things it does that can be hard to find in other programs, like cleaning up BHOs for one, and I started using Malwarebyte's AntiMalware, because it's fairly highly rated for a free program.  SpyBot and MBAM never find any real threats because AVG and STOPzilla work so well, but I still install them, mostly out of habit.  Plus, many people know and trust them, so they are more comfortable seeing them installed.  Most people have never heard of STOPzilla, but if you are having problems with a PC, then download and install the Free Trial, to see what you're up against.  I guarantee that STOPzilla will find something!  It's just a matter of how bad it is.

    So that's what I use.  I welcome any further comments.  And any recommendations on cleaning up Windows XP Pro on the T7400 to get some performance out of it.  I'm not sure that the owner is going to go for a rebuild like this, 2 years before it's necessary.  I'm just getting ready for the inevitable.

    Thanks in advance,




  • I would recommend you run some benchmarks on your system pre and post "performance and optimization" utilities (and application installations), as I have also found them to rarely make things better and occasionally make things worse.

    I would avoid AVG like the plague.  There are two things in common with every PC I work on where the user complains that it is slow - AVG is number one, and Vista with too little memory is number two.  AVG is unbelievably bloated and intrusive.  Symantec EPP in a business setting and MSE in a home environment run light and are effective and would be my personal recommendation - they stay completely out of your way an you never hear from them unless there is a problem.  Run periodic scans with MalwareBytes for possible programs that slip through the cracks (or were let through the front door :)).

    I would strongly recommend that you benchmark your system at every step of the way - before and after every change/addition to find out what is beneficial and what is detrimental to your setup.

  • Additional comments, I run Symantec EPP and Microsoft defrag automatically once a week.  I do not run ccCleaner nor any other speeup/performance improvement programs.  I find it hard to imagine how any program can impact a SAS drive.  By the way, there are NO Dell drivers on my system,  most are Mircosoft drivers, with an LSI driver for the SAS controller and a NVIDIA driver for the Quardo FX1700  card.  Question, are you running generic or cuystom memory?

  • SAS, SATA, SSD, or IDE ... if you screw up Windows, the drive type won't make any difference.

  • Hello TheFlash1932,

    Thanks for your comments.  I've been using Windows XP so long that I've come to rely on a couple of Performance and Optimization Programs, and I'm aware that so many of them do more harm than good.  I also know the value of CHKDSK and Defrag.  You suggest that I Benchmark before and after.  That's a suggestion that's good for Any OS.  Do you have a particular Benchmark program that you'd recommend, or maybe a couple of them for different things?

    You and others are saying that Symantec EPP is the way to go, and You recommend Microsoft Security Essentials.  But let me ask you how often you check behind them with another AntiVirus and/or AntiSpyware program, to see how well they are doing?  I might be opening myself up to criticism when I say that most McAfee, Symantec/Norton, and Microsoft AntiMalware programs are garbage, but then again, maybe you'd agree, because most people have never heard of Symantec EPP.  I saw it recommended in a syminar I attended, but didn't think twice about it, because I know how well My program preferences work.  I know that AVG slows down a computer, but I've found that most newer computers can handle it, and any AntiMalware program is going to slow down the computer while it's actively scanning. 

    But back to my question...  Do you take Symantec's word on the subject, that EPP is the best (because if you read the Box, they ALL say they're the best - and how can that be?) or have you ever run another AntiMalware program behind it, to see if it's missed anything?  And as far as Microsoft Security Essentials goes, I have never seen a Microsoft AntiMalware program ever actually find that much.  One recent AV Review included MSE in the reports, and said it was fast at fixing what it finds, but that's mostly because it doesn't look for much at all, so it doesn't have to fix much, which confirms my belief that M$ AntiMalware don't do much.  Therefore, it would seem that MSE lets a lot get by it, so how would you Know you can trust it if you never ran another AntiVirus or AntiSpyware program behind it, to see what was missed?

    I'm not coming from a criticism point of view, but simply asking how you've come to trust these programs, and pointing out my experience.  I regularly check the Internet for the best AntiMalware programs.  Norton/Symantec and McAfee never even show up in the Top 10.  When avast!, Avira, and AVG are always in the Top 3, between multiple Review Sites, I trust that.  The Protection margin between them is very small.  The major differences between them are performance issues.  I use AVG for my customers because of it's simplicity, and I've been using avast! for myself, and those who are more computer savvy, because avast! can act rather Paranoid at times, and that would confuse most of my customers. 

    I've had to select an AV program for my customers to Protect them - one that they can be comfortable with, and I've just had to accept the performance losses as a necessary evil, because there's no point in installing an AV product if it doesn't have the best protection you can find.  As for AntiSpyware, STOPzilla doesn't usually show up in an Internet search either, but I know from years of experience how well it works, and again, I've picked AntiMalware programs for their ability to prevent an infection.  You may or may not have seen that part of my post, where I talk about how I came to trust STOPzilla.  However, I'm always open to finding something better, so that's why I ask about your Symantec EPP, and how you came to trust it.




  • I have found Microsoft Security Essentials and Sphinx Windows Firewall Control to be adequate on all my machines. In most machines I have Malwarebytes' Antimalware, my personal ones I have the professional version. This is more than enough for my purposes. I rarely get infections when I do they are generally minor and are taken care by either Microsoft Security Essentials or Malwarebytes' AntiMalware. Plus the systems performance is running just as well 6 months later as it was when it was clean installed. This is for 18 computers... some others also had the clean install maybe 2 years ago and are still running fine. Only with an occasional odd manual scan with Malwarebytes' Antimalware and clean up with CCleaner/Defraggler.

    I see no point using AVG or McAfee because they have both been garbage and lead to severe infections on my friends and university machines. Plus with McAfee (don't know if AVG is as bad), I actually want to use the computer, McAfee delays everything. I suspect if you are putting everything on your machines you will get severe performance deterioration as in the case of the Precision T7400.

  • Most Norton stuff is garbage (and McAfee is garbage in my opinion).  The streamlined EPP (Symantec) is a different story.  Businesses will dump a product in a hurry if it doesn't peform just right, so they are not really in the same class as their other security suites.

    Microsoft Security Essentials is fairly new - and very different - so can't really be classified with any previous attempts by Microsoft at online security.  Reviews I have seen (probably ZDNet or CNet) have rated MSE right up with the best for overall protection.

    "Do you take Symantec's word on the subject"

    I never take a manufacturer's word for anything - they will tell me anything to sell a product (in fact, Symantec couldn't tell me how their product lined up against MSE when I asked them - out of curiosity - why I should renew our coverage, although I had every intention of renewing anyway).  I've yet to find anything with random scans with MalwareBytes, and nearly everything it has found, I know why it is there - invited by the user.  I'm not saying it is bulletproof - no AV is - or am I attacking the experiences you have had - but it has performed very well in my experience and runs with much less overhead and annoyance of other AV's.  I have run EPP on 100+ workstations for 3 years at work and MSE on dozens of customers' and my own systems since its release.

    I personally find nothing simple about AVG, and it uses 30-80% more resources than MSE, depending on which modules of AVG are being used (again - not simple).

    I have never even heard of STOPzilla, which is surprising - if it's any good.  I will check it out.

    Bottom line is, go with what works.  Everyone has a different approach to management and customer satisfaction, and preferences and experience can vary from one tech to another, so the end result might be different for one over another - and that's ok too.

  • Hello Natakuc4,
    I agree that McAfee and most Norton products cause extremely slow system performance.  I'm amazed that these products are still around, because they do cause computers to slow down so much.  This is a huge statement to how little most people know, and what they are willing to put up with, believing the Marketing Hype that they have the best.  Again, if you read the Retail Box, they ALL say that they are the best, and I say again, How can that be?  Retail stores only carry what sells, and if people have never heard of a program, they are not likely to buy it, so many of the better programs are taken off the shelves.
    I guess if you're extremely careful about what you do on the Internet, you might have very few infections, but I still have to ask "How do you know?"  If you are going by system performance, just because you don't see (can't detect) any system degradation, that doesn't necessarily mean that there's not an infection.  Many of the computers I get have many "Download" programs installed, like Torrents, and File Sharing groups like Kazaa, Napster, Limewire, BearShare, etc., and they have Kids that do things that you and I would Never do, so they need more than simple protection.
    I'm a bit surprised by your statement that AVG is garbage.  If this were so, then why would it continue to be ranked in the Top 3?  I have to admit that it slows the computer down, but since Windows is such a huge target for the Malware Industry, AntiVirus and AntiSpyware protection is a necessary evil.  One problem I've seen on computers with AVG Free is that they still have an older version installed from 1998 or 1999, because AVG didn't automatically get the newer versions as they became available, so they weren't fully protected, and they didn't have a good AntiSpyware program installed at all.  If your University friends are getting infections, the problem is probably more related to File Sharing programs, and Torrents, where infected files are quite common.  You have to have a top-notch AntiVirus program, and a top-notch AntiSpyware program, if you're going to do that kind on stuff on the Internet.  And since it's so popular, I continue to put these protection programs on computers.  It's not like I'm making a Mint by reselling useless crap - I'm trying to give my customers the best protection I can find.  AVG is Free, and you can get a Lifetime subscription to STOPzilla for $70 ($100 with a $30 Rebate).
    I just did a brief Internet Search (before I got your reply) on "what is the absolute very best antivirus -free", and BitDefender came up as #1 on two of them, but Symantec EPP didn't show up anywhere.  Personally, I don't trust BitDefender, and have found that many of these Review sites are run by people who are Paid to recommend one program over others.  I am more likely to trust Review Sites like, and others that aren't paid to do a review.
    I install AVG 2012 Free, STOPzilla, SpyBot Search and Destroy v1.6.2, MBAM, and CCleaner on every computer I repair.  Actually, not every customer wants to pay for STOPzilla, so on those computers, I install Prevx 3.0.  Prevx is a cloud-based AntiMalware program with a small footprint, that is very fast, but won't remove what it finds without a paid subscription, so I tell those customers to use it as an Indicator, to inform them of problems, and if it says it finds an infection, then they must run everything else to remove what they can find, and then run Prevx again, to see if that fixed it.  If not, then they have to call me.  But with all of these programs installed on a freshly rebuilt computer, the system degradation is usually very small, especially on newer computers, so there's another problem on the T7400.
    In your reply, you didn't mention Symantec EPP at all.  I know that a rating isn't everything, but even STOPzilla is on with a ranking of #27 in AntiSpyware, so if Symantec EPP is so good, then why doesn't it have a rating (there's none!!!) and why doesn't it show up more on the Internet when you search for AntiVirus?  You have to search for it specifically to find it.  I'd like to challenge you to download and install STOPzilla's Free Trial, to see what it will find.  It can also find Viruses that most AV programs miss.  I guarantee that it's going to find something - it's just a matter of how bad it is.  If you don't like it, or don't want to keep it, you can always uninstall it, or use System Restore to get rid of it, but you might be surprised at what it finds.  If you accept my challenge, then go to and click on the green Download Trial link.  I'm just saying that it's the best I've found, and I believe in it that much.
  • Hello TheFlash1932,

    What I meant by "AVG's Simplicity" is that it doesn't have the "Paranoid Behavior" that questions nearly Everything, which avast! can display, depending on the settings.  I know that most AntiVirus and AntiSpyware products will degrade system performance, but with Windows being such a huge target to the Malware Industry, it seems to be a necessary evil, so like you said, you pick what works.  With avast!, Avira, and AVG consistently showing up in the Top 3 of the Free AntiVirus programs, on multiple Rating Sites, I go for the best protection I can find for my customers, and myself.  The protection margin between them is quite small.  The biggest difference between them is overall performance, and system degradation.

    If Symantec EPP is so good, then why doesn't it show up in an Internet Search for AntiVirus?  You have to search for it specifically to find it.  And it never shows up in Reviews.  I know that a rating isn't everything, but even STOPzilla has a rating of #27 in AntiSpyware.  Symantec EPP doesn't have a rating at all on

    As for STOPzilla, you can go to and click on the green Download Trail button.  It will download an installer, install the programs, and run 4 steps.  When it gets to step 4, it will tell you to restart the computer so it to run a full scan, so do that.  When to computer restarts, it will perform the scan.  Depending on how many files there are, it can take a while, but subsequent scans will be much faster.  I guarantee that it will find something - it's just a matter of how bad it is.  If you don't want to keep it, you can always uninstall it, or use System Restore to get rid of it, but you might be surprised at what it finds.

    Good Luck.  

    I suppose that if you are very careful about what you do on the Internet, you might not need it, but you can get infections from going to, by being redirected to sites away from, so as I'm sure you know, you don't have to do risky things, like using File Sharing programs, to get a serious infection.

    I'd be interested to know what you end up thinking about STOPzilla.



  • I totally agree, but one of those programs had a warning from, not to run it on an SSD drive, so I thought that maybe the one I ran (not the one with the warning) may have messed with the SAS.

  • About Symantec EPP.  I have used it for about seven years.  I started using it when I started using Windows Server 2003 in addition to windows XP.  I am now running Windows 7 x64 and Windows Server 2008R2.   Every few months I run another on-demand scanners to check EPP.  I am yet to find failures in EPP.

  • EPP is distributed by Symantec as a business application, so it will not be considered (or even available) among consumer applications.

    SAS is no different from SATA from a user's point of view - or really from Windows pov for that matter.  The difference is only internally (to the drive), from the controller's pov (SAS controller is required), and the physical interface (different but backward-compatible with SATA) ... so your drive type does not determine which software should be run.  SSD's are a different story ... because storage cells on an SSD have a limited number of uses, things such as indexing and disk defrag's are often not recommended to run on an SSD - that AV probably did some type of operation not recommended for SSD's.
