Q6600 GO in a EVGA 750I FTW Extremely unstable after 3.2

Hi, im having one heck of a time getting my system stable past 3.2, All 4 of my core temps never go above 60C when my fans are on low, Ive tried all sorts of voltages and different multipliers and fsb speeds... but im a noob at this so could some give me some suggestions PLEASE!

  1. What speed is your memory running and is it at the proper voltage? Please provide more info about memory and BIOS settings.
  2. You may have reached the limit of your chip.
  3. My systems memory is Patriot Viper Series Model # PVS22G8500ELKN running at stock and specified timings of : 1066MHz 5 5 5 15 @ 2.1 volts which is the what patriot reccomends.
  4. My power supply is a PC Power and Cooling 750W continuous, 820W peak power. So i think i got enough power. My GPU is EVGA 55NM GTX 260 Core 216.
  5. Right now my FSB is at 1422 or 355.5 per core and My cpu multiplier is 9. Im pretty sure my cpu is running at 1.4 volts which is the lowest i could get. These newer GO q6600 suck way more power than the first released GO q6600... any way all my other voltages right now are on auto except the ram.
  6. 3.2 GHz is ok for the q6600, it´s not bad, if you disable Spread Spectrum (not sure if the bios on that motherboard supports it) you might get a little further.

    You need to take your Vcore off auto.
  8. problems overclocking?? you don't say!!
  9. V Core isnt on auto... its at 1.415
  10. ive tried raising the fsb voltage also
  11. Have you read the How To sticky?
  12. Generally nVidia chipsets don't allow you to overclock as well as their counterparts. I think it's your memory settings holding you back. It may simply be your board holding you back, but since your a newb I'm guessing if you just knew how to set the right BIOS options you could go a little further. Make sure you have disabled whatever you don't need like any power saving technology, (speed step although your BIOS may have a different name for it) and spread spectrum.

    First loosen your memory timings. Then set your FSB:Memory ration to 1:1. Once you max out on the core then you can raise the speed of your memory, otherwise you don't know if it's your memory settings that are holding you back.
  13. Thanks for the help Megamanx00 :)

    I have all power saving options disabled, and ive checked and my CPU is not throttling... The CPU features I have enabled are : Execute Disable Bit, Intel Virtualization Technology, and CPU fast Read...
    what reason would I need Intel Virtualization Technology for if im not using my computer as a server?

    Also when I try to overclock, do you think i should set the CPU multiplier back to 8 and just raise the FSB until I get excess of 1600? because my board is certified for 1600 FSB "and Beyond".

    Great Idea on the memory! :D

    Update: since my thermal paste is starting to set, all my temps CPU Temps are never getting over 50c with all fans on low
  14. BTW... all the spred spectrum options are disabled
  15. i have an evga 750i ftw with a q6600 go and i have the same problem. i can't get the cpu over 3.2ghz@1.5v and my ocz-sli memory over 1066mhz@2.1v unlinked + unsinked. also i cool the cpu with a cooler master aqua gate max and it keeps my cpu at 32*c. when i increase the voltage and fsb the cpu stays cool but never can boot windows.

    Well the Problem was my processor was dying. After a couple weeks it wasnt even stable at default speed and voltage, then it would not even boot :pfff:
  17. I guse your going to have to get a new chip.
  18. I have had two different 750i boards including a ASUS P5N-D and a EVGA 750I FTW. And I learned through testing numerous FSB settings and voltages that getting a stale OC above 3.15 GHZ and between 3.40 GHZ is a hassle. First suggestion is to turn off C1E enhancement because that really makes the OC unstable. Next try to use even numbered clock settings and keep your CPU and ram with a 1:1 ratio. Keep the ram at stock voltage and timings until you have tested your Overclock in PRime95.

    I have a q6600 GO as well and have it running @ 3.42GHZ would go higher but I live in the desert and it gets hot!
