Guys, I'm having trouble booting my Mach II GT cooled 920 in my Asus P5WD2-E Premium. I don't know whether it's a motherboard or cpu issue, but I never had anything like this happen on my P5WD2-Premium with any of my 6xx cpu's.
Now the motherboard/cpu combination boots just fine with the retail cooler, every time.
At no time however, will the combination start up as it's supposed to when the Mach II GT cooling device starts. Also I cannot boot the system up at any time while the Mach II GT is cooling down, regardless of temp. The funny thing is though, that after the Mach II GT has shut down again, I can boot the system up by shorting the power legs on the motherboard, which then also starts up the Mach II GT, and I can boot just fine. And I've done this quite a few times with temps as low as -51°C on the display, but mostly I need to get below -46 on the display. So I would think this points in the direction of the cpu, since the internal cpu temp could be higher if it has just been restartet, even if the display shows a lower temp, than if I'm doing a real "cold boot". Now if this was the only problem, it wouldn't really be a major problem, but annoying none the less.
The really odd stuff happens when I start to overclock. I get completely erratic and spontaneus reboots. Especially above 300 Mhz fsb. And I'm not lacking in PSU power by any means. I have a PC Power andCooling 850W psu, and I also tried with a Seasonic S12 600W, it's the same.
For instance I can run pcmark05 without issues @ up to at least 340 Mhz fsb, run any 3dmark, and even run memtest86 error free for hours at any given clock speed up to at least 4766 Mhz (340 Mhz fsb), however superpi 1M will fail within 5 seconds.... that is, mostly.... other times I can run superpi 32M along with dual prime etc. and it'll be fine for hours. Other times the system just crashes, randomly.
Now except the fact that I can't find any drivers for the marvel hd-controller that'll work, everything is working fine on the motherboard, have both an X'Fi soundcard and a tv-tuner in there.
Anybody else with any experience in this area? I've read about mikeguava having a cold boot issue with his 955xe cpu/p5wd2-p combo as well back in december of last year, but I couldn't see whether it was found to be the motherboard or the cpu's fault.
Any insight would be appreciated guys. Cpu/mobo combo is great, but I'll probably find something else for my Mach II GT system, and put this in another case if these problems persist.
