Does this sound like a PSU problem?

post #1 of 6
Thread Starter 
I've got a antec 620w high current gamer. Basically a seaonic s12ii thays only a month old. Whenever i try to play games my computer reboots withing 10-15sec. Temps are good and it only does this if i overclock the q6600 to 3ghz. Memtest86 passed. Could this be the mobo? Voltage is good.

Your answer is in the question. You're not achieving stable overclocks, you need to bump to voltage up a bit. After each overclock run a few loops or Prime95 to see if it's stable.

any overclock on the gpu?

The GPU is factory overclocked. The CPU actually passes Orthos for the full hour. I occasionally get random reboots just surfing the net or failure to boot into windows on loadup. I know my mobo isn't good at overclocking quads and I am thinking about replacing it with a P35 chipset board. However i don't want to replace the board if my new PSU is the problem. I've tried raising the voltage all the way to 1.4 even though it passes Orthos at 1.325. Also raised my NB voltage. My ram is all set to spec

sounds like vdroop. it says 1.4 but its only giving out 1.325

I know for my quad,

stock is currently 2.4ghz @1.124v

3ghz needs 1.35v

3.7 needs 1.40 sometimes 1.45

What speed is your ram set to mine at 3.7 is at 812mhz have you set it to its lowest speeds?

Not a vdrop problem. I did the pencil mod on the board and it actually puts out more volts tgen I set it to now. Ram is set at 667mhz with fsb @ 333mhz. Have tried running the ram at tge rated 800mhz with no luck
