I've just put an Opteron 165 in my PC and I'm getting some cold boot issues when overclocking. I had it running at 2.6Ghz for a week or so and it was flawless, but I've started to have problems. When I boot from cold, it can take up to 10+ times to start it on a bad day. Once it's up and running it seems fine; I can play games and do other intensive activities without errors or crashing, orthos ran fine etc.
Anyway, I was starting to think it was the mobo or the CPU, but it can't really be either. I've had this mobo up past 300HTT without a problem (I ran my old 3200 @ 8*300 for ages) and the CPU is obviously fine if it can sustain a week at 2.6Ghz with me thrashing it using BF2 a lot (so it's a fair assumption that if it can maintain load in windows it can boot at the first time of asking). Anyway, I knocked everything back to stock and it boots first time, every time. So, what could the problem be? Could it be a PSU issue or something like that? I rarely trust the voltage readouts in various programs, but mine are looking rather skewed these days (3.07v for the 3.3v and 12.45v for the 12v). Also, I've noticed that when I crank up the vcore, it barely seems to budge in the readouts. I'm not sure whether that's my MSI board undervolting though -- it's a known problem. When I set my vcore to 1.4725 the readout is more like 1.37.
The only other weird thing is that sometimes my sound in games will start going a touch loopy -- it almost sounds like someone blowing a dog whistle. Again, this only started happening recently and it's intermittent. It happens maybe a couple of times per week and, generally, restarting the game fixes it.
Specs:
Fortron Source 400W PSU (3 years old) -- spec: http://global.aopen.com.tw/products/power/FSP400-60PN(PF).htm
Opteron 165 & Retail cooling
MSI K8N Neo2 Platinum with Sideeffect's modded BIOS (1.C final)
XFX 6800GT @ Ultra
SATA & IDE HDDs
CD-RW & DVD-RW
Sound Blaster Audigy
Any ideas? Cheers.
