For the past six months it's like I've been on a wild goose chase tiring to figure out why my computer was failing at Prime95. Upping voltages, lowering multis, changing the FSB speed; nothing helped except running at <1500mhz with a FSB of 333. All of this ended when my Thermaltake 410w PSU shelled out on startup and I replaced it with a shiny new PC Power & Cooling Turbo-Cool 510 SLI. Now I'm Prime95 stable @ 202x12.5 (2525mhz) with a vcore of 1.75. Temps range from 40-48c. I couldn't be happier!
