A couple of months ago i used this video to help me out with my overclock Overclock 2500K.
The only difference i've got from that guide is the "C1" which i had to enable or my cpu wouldn't donwclock when in idle and my Ram timings/voltage as it is on the ram sticker.
Asus P8P67 B3
Intel 2500k with Zalman CNPS11X Extreme
Asus GTX 460 Top 1Gb
Anteq Truepower 750 Blue
Samsung F3 1Tb
and i had 2x2Gb G.Skill RipjawsX 1600 CL6 6-8-6-24 1.5v
no problems so far, but yesterday i got a new pair of identical DDR sticks, and with that BIOS config i can't turn the pc on i had to change the DDR to 1333.
How may i get it back to 1600 stable? Should i increase Ram voltage or something else?
Thank you all.
