OC'ing is all new to me...
System specs :
Intel E6750 @ 2.66 with Arctic-cooling freezer Pro Rev2
MOBO : Asus P5K (AI lifestyle bios)
mem : 4 gb (2dimm kit) GeiL black dragon PC28500 1066mhz (5-5-5-15)
GPU: Asus 8800 GTX (to be changed soon)
PSU : Tagan 2force II 700W
I already Putted the bus speed to 400 mhz. the cpu has a locked multiplier (8), so that gives me 3200mhz.
I wanted to keep the memory @ 1:1, but my mobo won't let me chance that, instead it gives me "numbers" correspending with the available frequencies i presume.. i think i chose 1033
As a result my Dram frequency is 500 mhz according to CPU-z with a 4:5 ratio...
All the other settings i left auto... (vcore , etc etc et)
My system ran with orthos all night with no errors, and temperatures are around 30-32°C idle and highest on full load was 52°c
Now i wanted to hit 3500mhz, but when i entered 430 for the bus speed in the bios and raised the vcore to 1.4V (all other settings where auto again) and for the memory i chose the "number " closest to 1066mhz...
Pressed F10 - save and exit
Reboot beep AND...
the screen stayed black...
After a while it rebooted and i got the message : Overclock failed
and i was redirected to the bios to try again
