Hi everybody

I registered here because i need help with overclocking and i dont want to fry something in my PC.

First of all i have this Mobo, cpu and ram:

I also have this cpu cooler:

...and arctic rc cooler for ram modules:

Now for the past 2 years i ran cpu 3,2GHz (a friend helped me with overclocking it to 3.0GHz then after a while i managed to get it to 3.2) but i was running winXP and everything was just fine. Now for the past half year since i installed windows 7 i got these random freezes on PC. Whole system just freezes it doesent restart it just hangs up. Sometimes i can work on the PC for hours and the other time it will freeze after 1 min or 2 after reboot. Its really annoying.

Untill yesterday i blamed nvidia gpu drivers because lots of people have complained about them but yesterday i found out the real problem for my pc hanging up is the OC.


Because all of these freezes i'm having now i've set cpu back to 2,66GHz but i would like to overclock it back up to at least 3,4GHz and to be stable.


I also read some articles on the internet about OCing e6750 to those speeds with air-cooling bot all of them have different ram and i'm a bit confused with that.



As far as i understand is my motherboard supports DDR2-800/667/533 memmory. So i bought "DDR2 800 (PC2 6400)" and they are working on dual channel so they both run at 400Mhz (400*2=800).


But now this thing that i dont unerstand is if set MHz for memmory to 1066 (533*2) will that be okay? Or do i need to buy new RAM for me to OC?
 
Please provide us more information about your overclocking settings so we can help you. What's the CPU clock frequency? Memory Multiplier? Voltages?

Have you ever run a prime95 or orthos CPU & RAM stress utility? Was the overclocking stable? What are the cpu temps under heavy load and idle?

From a first view it seems that a component is failing but these are just assumptions. Tell us more so to figure out.

P.S. You won't reach the 3.4 Ghz stable on air except that you live in Alaska...
 
It sounds like you need to increase some voltages. try upping the CPU voltage a few notches. Windows XP is not as intensive as Windows 7 and your system may no longer be completely stable.
