Overclock Issue

post #1 of 5
Thread Starter 
I have an Asus M3N78-VM motherbuard with an AMD 7700 Dual Core BE (2.7GHz) CPU. Overclocking Past 3.0 GHz Causes a blue screen Crash. Temp is OK at full stress. Any thoughts are appreciated. Thanks in advance!

Greetings to OCN.
I'm sure you mean the AMD Athlon 7750.

1.)Firstly, have you tried bumping up the voltage?
2.)If yes, keep an eye on the HT link. Keep it as close to 1800 as possible. (stock)
3.)If you've done all that with no luck, try checking the memory. Lower the frequency, or loosen the timings.

And make sure you're testing with something, such as Prime95

Fill out your full specs here. Have you tried giving the CPU more voltage? After a certain point it's going to require more voltage to be stable. You can up the voltage and use stress testing software like prime95 to check for stability.

Bumping up the voltage got me to 3100, but no further. I didnt mess with the memory. Any other possibilities? thanks!

How much voltage did you apply exactly? I used to have a 7750, here are some of my results. Of course all chips vary so you might need more or less volts for the same clock.





edit: if you have NCC in your bios, enable it. It's the Nvidia version of ACC which slightly improves overclocking with first gen Phenom (x2 7750 is a cut down Phenom X4).
