Need help with overclocking a q6600

[memory]

Here lately I have been getting the infamous "display driver has stopped responding and has recovered" error mainly when I play Crysis or run 3dmark06. Seems that alot of people say it has to do with an unstable system. That is what I am trying to figure out.

Right now I am overclocked to 3.3ghz and 1.35 volts and according to OCCT, my system is stable but I still get the error message.

There are a few things that are confusing me. In the bios, under System Memory Multiplier, there are 2 different numbers. If it is set on auto both numbers are 800. If I set it to 2.00 which makes the cpu to ram ratio 1:1, the number on the right changes to 734. Should both numbers always read 800? Do I need to keep the cpu to ram ratio 1:1?

What about the ram timing, should it be at stock speeds? According to cpu-z, it is running at 6-6-6-17. Stock speeds are 5-5-5-18.

I will try to post a pic of the bios to see if you guys see anything else wrong.

Hi Memory. I have come from a Q6600 and an 8800GT and have spent a lot of time playing with different settings in the past year. Actually I think too much time since, I only just started posting on a forum last week after a successful and satisfying processor and graphics card upgrade last christmas..

I recommend saving your system overclock settings and put everything back to stock and run your benchmark tests, try using prime95 for stability and run it overnight. My experience is 7-8 hours is a good indication (but a lot of people try 24hrs, good if you're not paying for the electricity bill )Monitor your temps and compare these with other temps you see online for the Q6600.

If any of these tests fail on stock speeds, I have a feeling that it can be a ram issue or worst case scenario the graphics card's own ram or an overheating problem.

If no errors then, try adjusting the system multi to 9x333 to begin with then run tests again...(with 1:1) and stock cpu core voltage to begin with slowly building up if unstable..(at this speed setting, anything above 1.4v is not necessary)

try to keep your ram timings as close to the manufacturer recommended settings and voltage (only when you're clocking it faster is the time to try higher voltages and different timings)


Anyway I'm sure a lot of the other gurus of this forum will be happy to help.

Goodluck and keep the patience!
