After adding my 2900XT, I've been experiencing strange instability issues.
System Specs:
Opty 170 @ 2.6GHZ
DFI CFX3200 mobo
2GB OCZ GamerXtreme OC4000
2900XT
Silverstone ST56F 560w, 36a on dual rail
SB Audigy2
Seagate Barracuda 120GB 7200.8
NEC 3550 DVD Burner
Linksys PCI Wireless adapter
Koolance Exos WC System
Ok, my CPU used to hit 2.8GHZ stable at about 1.5v. At first when I installed the card, I could not get passed 2.6GHZ w/1.4v. Anything higher than that whether it was voltage or mhz and my PC would completely shutdown during a 3DMark06 run. If I was at 2.6GHZ, everything ran perfectly fine.
I played around for a while and swapped the positions of the PCI-E connectors. The result was 2.7GHZ stable and I can even overclock the 2900XT to 825/910 with no problems. Trying for 2.8GHZ resulted in blue screens now instead of shutdowns. The error message in the BlueScreens is the infamous, "IRQL_NOT_LESS_OR_EQUAL".
Could my system be drawing close to 560w? I thought this PSU would be more than enough, but now I am afraid of pushing it to the point where it explodes and takes my system with it.
Anyone else running a similar setup? What PSU would you guys recommend for $150 or less?
