AMD® Phenom™ II Overclocking Thread

How many sticks of RAM are you using? 4 sticks stress the IMC quite a lot. I would try OCing the CPU-NB with 2 sticks and everything else at stock.
 
Good point, I am using 4 sticks. I will try putting it back to 2 and see what happens.

But then again I had no trouble with the NB clocked up to 2600 with 4 sticks of RAM on my 555. Should the x6 have affected that?

Stop looking at core temp Eddy, as that's the only way to explain you throttling at supposedly safe temperature levels lol.

The throttling to 8x is usually caused by the mobo power regs being overloaded/overheating.

I know that happens on my mATX board when I had my X6 (as my board is only 4+1 PWM).

Wouldn't have thought it would happen on the full ATX version though. :confused:
 
Thanks a lot for the help guys. Umm... what does that mean?

Doesn't sound good :(

Is there anything I can do?

Do you know of anything I should be reading to find out about this?
 
Forgive me being slow but are the VRMs the little black boxes in front of the cpu socket?

In lovely red:

Those are the mobo chokes. The bit that needs cooling is under the fancy blue heatsink behind them.

Get a flan blowing over that area, and you'll probably find the throttling goes away.

The CPU temp wise should be fine up to 62C.
 
Awesome thanks. I have a 92mm fan blowing in on my side panel. Maybe I can make something out of bog rolls ;) to direct the air over the VRMs.

Thanks for the help.
 
AMD's don't really suffer degradation like the Intel's, as they are built on a different fab process that isn't half as fragile.

1.5V is a perfectly reasonable 24/7 voltage for a Phenom II as long as you are able to keep the temps under 62C.
 
Just checking, you do know I'm talking about CPU-NB voltage Hex?

I've been told and read lots of different things. From don't go over 1.3v to you can go up to 1.55v same as the CPU. So I don't know what to beleive.
 
AFAIK CPU-NB has the same voltage limits (or there abouts) as the core itself.

So again should be fine. I'd be surprised if you need to put that much voltage through it though.

My old 1090T would do 2600MHz on stock voltage, 2800 with a tiny bump, and I never bothered with higher as performance increase is tiny.


My current 965BE is doing 2800 CPU-NB on 1.2V, and that's while running 8GB 1600MHz.

Search for AMD's "unleash the dragon" article, it gives you some voltage guidelines.

I posted that before somewhere, apparently it's for x4 and is outdated.

Trouble is knowone seems to know for sure, think I'll take my chances with 3000/1.4v 24/7. The extra 150mv is worth the extra 200MHz.
