ABit AX78 Overclocking/Stability

[justapost]

Can't get any info, installed Etch and started Lm-sensor detection and system froze
Does not happen with Ubuntu, its a Debian thing it seems.

Umm, that's why I run and asked for "i2cdetect 0" first.
That does only detect the addresses where chips live and does not test the chips. I'd not run sensors-detect with a phenom mounted. I tested all other boards i have here with an X2 cpu. The system only froze on the Sapphire board,not on the M3A(770) the GBT780G and the M2A-VM (690G).
Running "i2cdump 0" with the i2c-piix4 and the i2c-dev module loaded did never freeze a system but it makes the smbus/i2c chip unusable till i restart the system (cold start). It does not interfer with the it87 module which is used for the sensor-chips on all of my boards.
I wonder if "i2cdump 0" also shows a chip at 0x2e, whom is responsible for the freezing.
What version of lm-sensors comes with etch? I use lenny so i had the latest stable 3.0.1 version here.

This is the only official info I know, not much there though;

Thanks, that is from the SB600 docs i guess?

Hmm.. I've already done this test quite a while ago. With mine what caused freezing at stock volts also caused it at 1.55v - if it was idle instable, its always idle instable no matter what you do

Yeah but it can be that with 1.55V the bad clocker at stock whould have been stable and the better clocker are causing the freezes now because they do not like those hight voltages.

For me, its just some weaker cores, I mean, you can see my above results and compare that I was stuck at 2700MHz before max

For the p-states amd says the multis and dividers must be equal for all cores.
We know that this is no requirement but I'm not so sure if it will not cause problems 24/7 longterm.
My last 9850BE also had a bad third core and the fourth also was no good clocker. Cores one and two ran 3GHz at ~1.325V.
