CHV Bios settings help

post #1 of 6
Thread Starter 
Okay, I've just upgraded from an M4A785TD-V EVO to a CrossHair V.
Now I'm having a problem unlocking all 4 cores on my 555.
With my old board it worked great. I just enabled all cores, set my o/c frequency and voltage and that was it. Very simple, it just worked. I had it set like that for about a year, and never had a single stability problem.

With the CHV, I've got stability problems with 4 cores enabled. I can boot Windows, but running the WEI test it will lock up. I know the cpu can do it, because it worked great on the old board. So I suppose I just need to figure out the right combination of bios settings to make it stable on this board. But I'm new to this, and this board is LOADED with crazy configuration settings, I don't even know where to begin.
I've tried playing with a few things like spread spectrum and load line calibration, no effect.

Can anyone point me in the right direction? What can I try setting that might help make this work?

No suggestions?
Anyway, now I'm starting to think I've got a bad board. It crashed last night while running 2 cores at stock speed.

Try disabling one core at a time and test. Just want to eliminate the cpu being at fault. Also give us more info like your voltages and other settings and what type of crash is it, freeze or blue screen?

I know the cpu isn't at fault because it ran perfectly on my previous board.

The latest crash was a blue screen. That was with all settings at stock or 'auto'.

Just an update. Nothing worked out. I've actually started hearing of other people with this board having stability problems with Phenom II's that aren't even unlocked.
So I returned the CHV, and went back to my trusty M4A785TD-V board. Now I'm running x4 again with no problems.

Once I upgrade to BD, I'll need to change the board again. Hopefully asus will have gone through a few bios revisions by then and get their stability issues sorted. Once that day comes, I'll miss this little M4A. It's a great board, very underrated and somewhat unknown. It's overclocking capabilities are far greater than its original price tag would lead one to believe.
