Phenom II x4 820 Refuses to Go Above 3.2GHz

post #1 of 7
Thread Starter 
I recently built a computer with the Phenom 820, and from what I've seen on these forums, its supposed to be a pretty decent overclocking processor, most people seem to easily be able to bring it to 3.5GHz, the highest I've gone, unfortunately is 3.276GHz!
Something doesn't seem right, I know not all chips are equal and all that crap, but the fact that I can't even get to 3.3GHz seems suspect.. Could it be my motherboard? I have a Biostar N68S3B. Thanks in advance!

The biosta mobo u have is low end and has a chipset and vrm system both very unsuitable for ocing the phenom ii.

If you could fill out your system specs (http://www.overclock.net/specs.php), it would definitely help.

Starting from scratch, I'll ask the following:
- What voltages have you tried?
- Have you ruled out your RAM?
- Are you still on stock cooling?

Sorry, I'm a noob here... hell, I'm a noob to building PCs :3 I just got enough money to build this rig.
My bios gives 3 voltage options, +1%, +2%, and +3%. Default is 1.2-1.3v, +2 is about 1.4v, and +3 is 1.5v.
I've tried them all.
Though, I've recently made a bit of a discovery, if I underclock my memory to 800MHz, I can easily overclock my processor to 3.5GHz in the Nvidia Performance Tools. This is with default voltage. However, if I set the Nvidia thing to overclock to that on startup, soon as I click yes or ok or whatever it was, the system crashes o.0 So, it definately can overclock.
Another find I made was if I overclock the memory to 1600MHz, I cannot overclock the processor to even 3GHz.
If I set the processor to 3.5GHz with the memory at 800MHz from bios, however, I get checksum bad error, and have to load bios defaults -.-

No, the cooling isn't stock. (:

I think xd_1771 is right. You have a pretty bad mobo for OCing.

Memory multiplier definitely has to be set down one notch to OC via ref clock - as does NB multi, HTT multi, etc.

I should note: 95W is the max TDP on this board already; it uses a 3-phase PWM design with no split phasing based on AM2 reference standard, this is not very suitable for most AM3 quad cores to begin with. Plus the limited hypertransport speed and NB speed will not make a CPU speed OC very worth it. Also it is an nVidia chipset, also not as suited for an AMD OC.
