Stability issues, where to start ??

Hi all !

I´ve been doing some OCing to my Q6600. I´ve pretty much used a "template" I´ve created using all the info I´ve read about similar setups. The sistem boots, its OK at idle (hotter than before of course), but I get errors when running prime95. I might even get a blue screen when running two or more times...

Since I´ve used settings I´ve "borrowed" from other people I don´t really know where I should start increasing voltages (if I have to...). Any suggestions ??

Here is my sistem running prime95 (and sistem info):

I forgot to include realtemp temps on the screenshot, but its 63-65ºC on all 4 cores (its actually realtemp the only temps app I´ve calibrated a bit). Room temp is 25-26.

Here are my BIOS settings:

More about stability issues start
  1. more vcore might help try 1.35 up the fsp aswell to 1.3 and the nm to 1.3 see if that helps also why are you useing the 8x multi? try 9x400
  2. Thanks richardscott.

    I was using 8x since I felt like 3,2 GHz was enough ! I dont want more heat, or at least rise it as little as possible, cos I think this is already quite hot (so I wanted to rise voltages as little as possible too). My goal was to be able to run the memory on 1:1 and with 400Mhz FSB
  3. your voltage is fine i had my q6600 upto 1.5v and its still working, as for temps you cant really lower them unless you get a better cooler or lap it
  4. Thanks again ! I dont think I´ll go that high :P but I´ll keep it in mind. Regarding the temps/cooler issue.. I guess there is no other answer
  5. temps are ok tbh keep it below like 70c mines at -56 :D
