I recently in the last month purchased this mobo in hopes of getting a good overclock. I recently got new memory (had twinx Corsair PC3200 512MB, now twinx Corsair PC4400 1GB). I was a socket A OC veteran, but A64 is new territory for me.
My current setup:
MSI K8N Neo4 Platinum (non SLI)
A64 3200 socket 939 90nm Winchester
2x512 Corsair twinx PC4400 @ 2.5-3-3-10
XFX GeforceFX 6600GT
Seagate Barracuda IV 120GB ATA100
Antec Truepower 550W PSU
Thermaltake K8 Venus Silent boost HSF
Everything was swell when I started OC'ing. I was up to 10x220, no problems. I tried 10x230, and it was a no go. I had already dropped my HTT to 4, and made sure my memory had 2.75v (what Corsair recommends). I also bumped the chipset voltage to 1.65. After doing this, windows booted up. I was running a benchmark in Sandra 2005, and it locked. Ok, I thought I might need to give the processor a little voltage bump. So, I think I put it to 1.45v. So, when I hit F10 to save and exit, the system just shut down, and the power light on my case started flashing. It would not reboot. I had to clear the CMOS, and set everything back to stock. It almost seems like if I try OC now, the system does this. Anyone else had this problem, or know of a solution?
Update:
Ok, have done some more messing around. I am not having any problems with complete shutdown if I just tell it to increase CPU voltage to +8.3% (trying to give it a definate value seemed to shut it down). I have booted and run sandra at 9x250, HTT x3, memory 2.5-3-3-10 1:1, and everything was working just fine. However, if I try to reboot, it will not beep, and the monitor light just flashes like its not getting a signal. I can change settings in the bios, and most of the time boot into windows and play games, benchmark, etc. however, if I reboot, or shut down and try to reboot, it won't come back up. This is very frustrating!!
