Hi. I'm currently using an AMD Phenom II X4 965 BE that has a stock clock speed of 3.4ghz, but only runs at 800mhz. I've seen forums suggesting its AMD's Cool 'n' Quiet function, although I'm certain it's not. After disabling it, there is no difference. My motherboard is a FOXCONN A74ML-K, and on its site, it clearly states it supports Phenom II processors. You can get your info here: www.foxconnchannel.com/ProductDetail.aspx?T=motherboard...
I've read an article on this site which states that if I use Overdrive to set it to its default clock speed, it will be sorted. I'm sceptical about this, since I'd be making my motherboard do something it isn't meant to do. Would it be safe to do so? And would I need to disable Cool 'n' Quiet before I did it?
Any other suggestions would be greatly appreciated.
reburon, you've put a 140 W TDP cpu in a 95 W socket. There's your problem. phenom 2 cpu's with only 95W TDP are compatible with your mobo. your cpu is safe but mobo will likely die under so much pressure.
that's probably because, the processor is being underclocked and undervolted by the mobo. CPU-Z would be reporting false values. There are only two variants of 965 both arfe "deneb" with the C2 stepping @ 140W and the C3 stepping @ 125 watts.
Your motherboard's VRM will be strained trying to feed such a powerful processor. keep an eye on the mobo temps while you use your cpu. VRM mosfets are designed for 85-95 C for most board with a 95 W TDP support though higher end boards will have a higher thermal ceiling.
can't you get a board with am3 support from some auction site?. you must check your cpu stepping and accordingly get a 125/140W mobo.
