Hey

Currently have my Q6600 at 3.0ghz (thermalright u-e) on an MSI neo2-fr with 4 GB of corsair xms2 ram. It runs great and has idle of temps of around 35 and load temps of around 55-60, hasn't crashed once and been extremely stable.

Now, the problem comes when I try and overclock to 3.2 - it'll be fine for a period of time and then blue screen on me (sometimes after two hours, sometimes after 5 minutes). Temps seem fine, is there any other reason for this? Is it a case of increasing the voltage?

According to core temp it's currently running at 1.3125v (is coretemp accurate?) at 3.0ghz - when I increase to 3.2 should I increase the v also? At the moment it is currently set to auto in the bios.

Any help appreciated
 
As your vcore is set to auto and crashing at 3.2, and you are running 4 sticks the additional strain on the NB memory controller you may need to increase the NB voltage.

Makes sure you write down your voltage settings. Increase your NB incrementally this may provide some stability. Are you running prime to stress out of interest?

Nope - I ran prime at 3.0ghz for an hour or so and it passed fine, I didn't really have the patience for any longer. I guess I just kinda assume 3.0ghz is fine on this chip

It crashes playing crysis or any other game really. Stranglehold it held out for aaaages then crashed randomly. It fails prime sometimes after 5 minutes, sometimes after half hour, doens't tend to last long though.

NB = North Bridge I assume? What is a safe limit for the NB? Just out of interest, don't want to increase and end up blowing it! :)

cheers for the help
 
Ok on that info leave the NB voltage on auto for the moment. It would appear your O/C is unstable relating to Vcore

Keep your O/C at 3Ghz. Up the Vcore Voltage in the Bios to 1.3225v run prime for as long as possible (pref over night 8hrs). If it fails increment the Vcore again by a notch and stress test again.

It is a long drawn out process, but you patience will pay off.

I dont know if this helps. If you have 4 x 1GB,

try it with just 2 sticks.

My Q6600 GO would'nt go over 2.952GHz (9 x 328) on a P5B-E with 4 x 512MB Geil 6400

I tried everything volts, divider etc for weeks, eventually I took 2 sticks out &

now I have it @ 3.2 stable 24/7 @ 100% on all 4 cores, and still going up, it was as simple as that.
