Dell Dimension E520 CPU Upgrade

This question is answered

Hi, i'm upgrading my CPU because this one is too slow, and the one I am getting I will be paying 80$ instead of the usual 250$ price. I would love to know if they are compatible with my system. All I know is they have the same socket type (LGA 775). Heres the link to it : http://www.newegg.ca/Product/Product.aspx?Item=N82E16819115060CVF 

These are my current computer specs : 4GB DDR2 RAM, 1GB GDDR5 128bit AMD video card, 1.86Ghz Intel core 2 duo CPU (Rated at 3.33Ghz), and a 305W power supply.

If I would need to change the power supply, I'd love to know because I have one here that is 750w I could also use. Thanks.

Daren

*P.S : I know i'll have to update my BIOS because I am currently at version 2.2.1, and the latest is 2.2.4 (Or something like that) should I just bring it to somebody to do it for me, or is it easy to update? I don't know where the find them, so if possibly somebody could direct me, I have Pheonix technologies BIOS.

Thank you very much again!

    The Core 2 Quad Q9505 Yorkfield 2.83GHz LGA 775 95W shown in your link is not compatible with the e520.

    All the Socket LGA 775 processors, listed HERE are compatible.

    There should be no need to upgrade the  power supply for a processor upgrade.

  • This thread is a little bit old now, but you will find that the Q6600 and the Q6700 will both work in the E520. In fact, I have a QX6800 (Intel Core 2 Extreme @ 2.93GHz) installed in my E520 and it works perfectly. I have upgraded the PSU to 650w but that was more on account of the graphics card (Radeon HD7850). I Have 8Gb DDR2RAM installed with Win7 64 bit and an OCZ SSD system drive. The whole rig delivers rock solid reliability and enough power and speed for pretty much anything.

  • Further to the previous post, the E520 will work with any of the CPUs supported by the Intel P965 Chipset, listed here

  • Thanks for the update!

  • being somewhat new to the upgrade scene, is it hard to upgrade the chipset to accommodate more memory?  i've added memory to my machine, but it only recognizes 3 of the 4 Gigs of mem.  obviously, i need to perform this type of upgrade to access the memory.  i thank you in advance for your input.  investigating the cpu upgrades you recommended.  

  • forgot to mention i also have an e520  

  • I suggest opening up a new thread for this question.

    It is not a chipset issue, it probably an operating system problem.

    When you have a 32-bit system, this does not recognize 4gb of memory, 3±gb is all a 32-bit system can address.

    Basically what it means is, while you can install 4gb of memory in the system, the reason it’s not recognized is mainly due to 32-bit processors and/or 32-bit applications on memory address limitations.

    64-bit processors & operating systems will recognize beyond the 32-bit limitation.

  • The E520 uses 64-bit processors, so upgrading to a 64-bit version of Windows is feasible. Windows 7 product keys are interchangeable between 32- and 64-bit, and thus can be reused for that purpose.

  • Any of the Core2 Duo or Core 2 Quad processors support EMT64.

    I do not work for Dell. I too am a user.

    The forum is primarily user to user, with Dell employees moderating.

  • As noted in some other replies to this post, the memory issue you are experiencing  is not a limitation of the chipset, it is a limitation of 32 bit operating systems. They will only recognize a little over 3 Gb of RAM. To access the full 4Gb you have installed, you will need to install a 64 bit operating system. As noted elsewhere in this thread, I have 8 Gb of RAM installed in my E520 and Windows 7 64 bit can access all of it. No chipset upgrade required.

  • I'm aware this is an old thread, but it's been very valuable to me, having just acquired a 4Gb RAM, P4D-2.80gHz E520.  Thanks to all.

    My usage is non-gaming but I multi-task.

    I am shopping for a 'Q' or 'QX' cpu in one of the flavors Neil posted, after installing a single slot Radeon HD6450, running the stock PSU w/o trouble.  The BIOS is now 2.4 plus Sammy SSD830 + Win7 Pro/32 bit.

    Q:  Will reinstalling Win7 as a 64 bit O/S show much speed improvement, with access to the 'extra memory?

    Q:  will the 'X' version, with the quad cores show much speed improvement, given non-gaming use?


    Thanks in advance.

  • Installing a 64 bit OS will result in a slight but noticeable improvement in performance due to access to the full 4Gb of RAM. however, the real advantage is that you can install higher capacity RAM modules; up to 2Gb per slot, and get the full benefit of the upgrade. Regarding the CPU, I did notice a slight improvement when upgrading from the Q6700 @ 2.66GHz to the QX6800 @ 2.93GHz but it wasn't dramatic. One of the advantages of the Extreme series CPUs is a fully unlocked multiplier, which is designed to allow extreme overclocking. The trouble is the Dell BIOS does not permit hardware-based overclocking at all so you are stuck with the stock speed. It may be possible to oveclock the CPU using software such as ClockGen but I haven't felt the need to try it. Nonetheless, I am more than happy with the QX6800 which, coupled with 8Gb of RAM, delivers awesome performance. For your purposes a Q6700 or even a Q6600 @ 2.4GHz would be adequate and would deliver a huge performance jump over your Pentium. They are also somewhat cheaper to buy second hand than the QX series.
