Overclocking AMD Phenom II x4 920 !

post #1 of 11
Thread Starter 
So i started overclocking my Phenom II x4 920 and currently i am at 3.5Ghz Stable

Specs are =
CPU = Phenom II x4 920 2.8Ghz @ 3.5Ghz 1.392V 14x250Fsb
Ram = OCZ DDR2 2x2GB 1066Mhz
Mobo = Asus M2N68 Plus
GPU = Club 3D Radeon HD 4890 Superclocked edition [Oc'ed more] @ 985Mhz/1085Mhz Stable.

Temps with prime95 after 1 h = 57C [Made a "Ghetto" mod !]

Some Cpu-z information =

HT Link = 1253Mhz [nForce chipset]
NB Freq. = 2005Mhz
DRAM Freq. = 334Mhz
FSB:DRAM = 3:4

The guestion is that should i go for more, everything seems to be stable neither the temps are not high.

Without having adjustments for cpu/Nb or HT link, you may get a little more out of the cpu freq.
You can bump the ram freq to 400, since you are running 1066,that will put you at 1000 .

Are you talking about that ram freq setting with auto-200-233 and so on ? Should i pump it up to 400 mhz ? And should i pump up some more FSB since its 250

Yes,set ram to 400.
you can try more on the fsb, but your temps are pretty close to the limit also.

Okay so now the Dram freq is at 400 and now my Dram frequency in cpu-z shows 501Mhz. Seems to be stable smile.gif
I tried 255 fsb and 260 fsb but got bsod after just after the wallpaper showed up. So i lowered it back to 250
Should i go for 1.45v and then go to 260fsb ? Haven't tried that yet.

You could try raising the cpu freq by 1's,eg;251,252,253...
More volts may help, but will increase temps.

I noticed a strange problem redface.gif ! Im benchmarking with 3DMark Vantage after every restart/oc. When i changed dram freq to 400Mhz it showed 501Mhz in cpu-z. I did 3dmark vantage and got a bsod. 3.5Ghz and 501Mhz dram redface.gif! Then i lowered dram freq to 266Mhz and pumped up fsb to 255 and now its stable and 3DMark Vantage running fine. Everything seems to be stable and 3.55Ghz temps under 60, should i go for even more ?

Maybe your DRAM runs at 1066MHz but it needs 2.1 or 2.2V of Vram. Default is only 1.9V or so. rolleyes.gif

Okay so i got 3.7Ghz Stable ! Awesome !
The only problem is that i have pretty high temperatures... Idle is like 50C and prime95 full load 68-70C. Is it safe to play games with these temps for like a week or so, because i will buy a better cooler smile.gif ?

If you can hit 70C on that chip at 3.7Ghz stable, it has much more in it with cooler temps. Those temps are high I would advise scaling it back down, lower the voltage, and wait until you have proper cooling.
