Dell 690/Overclocking?

  • Where did you purchase the larger 120mm fan for the FBDIMM?  Is it a direct plug-in or do i have to modify the plug-in?  Which wires on the power supply did you use to hook up your fans?  No problems after hooking fan wires to power supply?  Thanks!!
  • Yes i purchased the 120 mm fan for the memory.
     
     
    But i was hard to adapt because the size is different, i ve fix the fan on the metal mount by bending the metal, it's a dirty modification. (don't really pride of this...)
     
    i ve put directly to 12 volt the 120 mm fans, by an adaptator to a Molex.
    But i got the Fan detection error when booting, so i had to redirect the yellow wire from the fan, to the white wire from the dell previous fan connector,
     
    as this i don't have anymore the error message, and more i got the monitoring of fan speed.
     
    But i was need to cut the previous mem fan, and soldering white wire to the new fan (to the yellow wire)
     
    The result is less noise, but i can't overclock at 200 mhz like with original fan. i m at 190Mhz now => 3420 Mhz (stock is 3 ghz)
  • How long did it take for your stock mem fan to reach max temp while overclocking?  The longest i would probably use my processors when overclocked would be about an hour.  Mostly i use for around 16min average.  Thanks.
  • about 5 minutes intense computing i would say
  • Hey,  I tried the command like you said but it didn't seem to work?  Is there something i might be doing wrong?  I typed it like you said but it's not doing anything.  Thanks.
  • first : lunch a program to monitor FSB frequency.

    Second : "I:\Program Files (x86)\SysTool\SysTool.exe" -fsb ICS93S401:185


    Change "I:\Program Files (x86)\SysTool\" to your Systool directory
    Change 185 to the desired FSB frequency.

    should work without problem.

    Best Regards
  • I have core temp monitor that shows my fsb at 332.5 x 6.  Here's how i typed it in the "run" command menu.

     

    "C:\Program Files (x86)\SysTool\SysTool.exe" -fsb ICS93S401:333

     

    Of course i tried setting it to 340 but still nothing happened.  Could it possibly be my windows OS?  I'm using 64 bit but it can run 32 bit programs in the (x86) program files.  Not sure why it won't work.  I also typed it like this and took the hyphen away from the fsb like this but only got a blue scree again.

     

    "C:\Program Files (x86)\SysTool\SysTool.exe" fsb ICS93S401:333

  • here is my log information if it helps any.  Thanks.

  • Hello,

     

    i don't think it's your OS, because i got the WinXP 64 bit too, and it work nice.

     

    i think you don't have not this chipset ICS93S401, which could tell that you cannot overclock your PC.

     

    maybe another Dell precision 690 custumer could tell if their attempt to overclock worked.

     

    i ve just changed my Xeon 5050 to a Xeon 5020, and my new command to overclock is

     

    "I:\Program Files (x86)\SysTool\SysTool.exe"  -fsb ICS93S401:395

     

    (instead of 333), work perfectly.

     

    Maybe you could see inside your PC, what chipset you have to control the frequency generation, rather hard to find the good chipset. you should see on Google how to find the PLL chip.

     

     

    My log is

    Maybe CoreTemp could tell you by what chip it is reading the FSB value

  • Okay.  I will try and find out how to find the PLL chipset. I'll keep you informed and see what i find out.  Thanks!:smileyindifferent:
  • Here is what i got from the PLL chip off of my motherboard.  Tell me which number i should use for the PLL?  Hope this is the right one.  Thanks.

     

    ICS  7325328

           0706

           9FG1201CGLF

  • Ok as your datasheet of the 9FG1201CFLF  http://www.idt.com/?partID=9FG1201CGLF

     

    said, "... such as the ICS954101 or ICS932S401, drives the ICS9FG1201. "

     

    you should find another chip near the one you have already find to know which one of both lead your 9FG1201CFLF.

     

    the ICS932S401 is the one present on my computer (dell precision 490), if you don't have the ICS932S401, you should have the ICS954101.

     

    you should look on your motherboard exactly what chip control the 9FG1201CFLF, and then after type on google the ref to know if it's readable/writable PLL.

     

    Good luck

  • So there is another chip that runs into the chip i told you and that chip should have the ICS954101 or a similar ICS number? That number should be the one that systool can read?  Thanks.
  • No, there is a another chip that DRIVE the chipset you talked, (not into the chip but around the first)

     

    But, you take the bad reference, exemple :

     

    ICS  7325328          => ?

           0706               => ?

           9FG1201CGLF   => Chipset reference

     

     

    That was the same sheme to take the good ref on my PLL chipset, on my precision 490
