CPU only fails prime with APM disabled

[soccerballtux]

I started this thread: thought I was having RAM problems. It looks like I wasn't-- I'm only failing prime when APM (AMD Power Management) is DISABLED. Which is a shame because it throttles the CPU on heavy loads.

After letting this run for another couple hours I'm going to disable APM, but also disable C1E, and see if that helps anything.

any other recommendations or inputs are welcome.

Maybe this belongs in Motherboards...hm...

Maybe your OC isnt as stable as you think?

Anything is possible, but I think it's much more likely that his not very expensive motherboard is having problems keeping that FX 8310 overclocked that high.

I have a feeling that is true.

sorry, wasn't clear; I'll have these problems on stock vcore at the stock non-turbo speed of 3.4ghz.

I would agree except that this is an 8-VRM model and there is thermal throttling that steps the frequency down when the VRMs get too hot. I haven't been engaging that--I'm nowhere near it. Additionally, I have mounted a fan to the VRMs and can crank it to 100% and still experience this issue. Not proof, but support that something else is defecting here. What do you guys think? Is 190w on the CPU really too much to expect here?

I think I have solved this by leaving APM on and also enabling previously-disabled HPC; which in retrospect doesn't matter to me anymore since I was leaving it at 4.3ghz all day anyway. Mobo no longer pulls the CPU back to 2.9ghz/3.7ghz to maintain the 95w TDP, and I get the stability.

edit: DANGIT! I was wrong.
