OC AMD Phenom II x4 945

[stephen1983]

Hi, I am new to the forum and OCing for that matter. I have an AMD Phenom II x4 945 on an Asus M2n68-VM MB with 8 GB DDR2 dual channel RAM. I am using the Antec Kuhler H2O 620.

I am able to Oc to 3.7 GHz (in BIOS) with core temps staying at 46C using Prime95 In-place large FFT test. However, when I increase to 3.8 GHz my system crashes. I have tried to mess around with core voltage, memory voltage and timings but to no avail. I am starting to suspect that my MB isn't up to the job?? I am hoping to push the CPU to 4.0 GHz.

Basically, I am looking some guidance on how best to achieve this. First and foremost, should I upgrade my MB??

That motherboard is 5-6 years old...and doesn't have a split power plane to give CPU-NB voltage a different voltage than core voltage...

You should probably upgrade your motherboard.

Thanks for your reply. An suggestions as to a good MB upgrade?

If that is too pricey, then there are certainly cheaper options.

A little on the pricy side. Perhaps something around the $95 mark?

No-frills budget oriented board, but should get the job done.

There's that board, or this one for $10 cheaper. They seem to chase each other in price.
