I'm trying to overclock my AMD 955 to 4Ghz but i can only run prime95 for 15-20 min before i get a blue screen or my pc reboots, i tried different combinations of CPU core multiplier, HT ref. clock... I raised my voltage to 1.475 but my CPU temperature went up to 60 C.
Any suggestions to have more stability?
Also i'm planning to have another 4870 in crossfire, would i have to upgrade my PSU?
AMD Phenom II X4 955 Black Edition
XFX Radeon HD 4870 1GB 256-bit GDDR5
G.SKILL 2GB (2 x 1GB) 240-Pin DDR3 SDRAM DDR3 1600
Thermaltake Contac 29 120mm CPU Cooler
hec X-Power Pro 600W
My cpu cooler is a thermaltake Contac 29 with two 120mm fan, i'm pretty sure it can't make it to 4Ghz with a little more tweaks but i just don't know what to do.
For the crossfire 4870 i think my PSU have all the connectors needed but now that i know more about power supply's i'm pretty sure it's a cheap one compared with other 600w PSU even if it did the job well so far.
