I overclocked my CPU by about 10%(My CPU at 3.2 GHz and my ram at 1600 MHz) by X.M.P mode in bios (which automatically sets blk and Dram voltage and timing) (blk = 160 , CPU multiplier ratio 20) . but when I ran prime 95 blend test after a few minutes it crashed and my temperature were well below 70' C .
my PC specs:
.
.
main board P7P55D LE - ASUS
CPU core i5 760 intel 2.8 GHz - evercool transformer 3 heat-sink and fan
GPU MSI Nvidia gtx 670 power edition OC
8 Gig ram (4 & 2 &2) corsair XMS3 1600MHz ( notice that I'm using 3 out of 4 DDR3 slots)
PSU 600W
windows 7 pro 64 bit
.
.
I read in XMP mode the bios increased the ram voltage to 1.66
and I set the vcore voltage to 1.25 (If I go higher , the number gets yellow which I guess means "don't do this ")

maybe my PSU can't handle that much power. but, a newly bought (80 BRONZE certified) 600 W PSU has to be able to handle a LOT more... let alone a mere 10% overclock .
besides my cpu cooler is new and as I said , the temperatures didn't even reach 70'C.

so what do you think is the cause? I would appreciate your answers.

looks like max voltage on that cpu is 1.4, i wouldnt go that high, but 1.35 should be alright. yellow just means caution when overclocking on an asus board. mine is in the red on my 3770k, so dont worry about the colors. as long as your cpu doesnt get to close to max temp, you will be fine.
