Phenom 9500 w/ MSI K9A2 Platinum

[Oldguy932]

Its not bios, the BE will take it. That voltage I put to 1.3v and then leave it alone, moving it does me no good. 260htt just will not stabilize no matter what I do. I just dropped it back to 255 and I'm gonna prime it for a while. I might just put the BE back in if I have to deal with this much crap from the htt.

Specs to try and get 8 hours stable

HTT=255
CPU=11.5x
NB=9x
HT-LINK=1.8ghz

vCore=1.275 set, 1.26 actual
vCore-NB=1.3 set
vNB=1.3 set

I'll take another look at the clamshell later, I'm busy for the next 6 hours or so.

@oldguy932: Do you get that 1.3V stable wall chilled or with "normal" aircooling?
Also what does cpu-z report for the voltage in idle and under load?

[Oldguy932]

Whatever is set in bios goes down one setting under load. 252 wasn't stable, gonna drop the multi and see how everything else scales right now.

On the 690G chipset there was a different behaviour, that drop increased and also the difference between what i set in the bios and what cpuz reported. High drops where a sign for too high vcore there.
I have a 790fx mobo since a few days and get an behaviour like yours.

On the M3A ref HT's above 260 where posiible with 533 mode for the memory. Modest watercooling only helped in power consumption but i could not gain higher frequencies.

I do have memory set to 533. Right now cpu multi is at 8x, htt at 260, and cinebench 10 seems to be running pretty good right now. Still doesn't explain the instability at high clocks though. I might just be going for the superfast nb and have to live with a slightly lower cpu speed than I would like.
