My OCed comp at the sys Spec. below
this is my DDR SDRAM
http://www.newegg.com/Product/Produ...N82E16820145500
I think it use Promos chip

I've OCed like this: FSB:240MHz
1/ Didn't change the bandwidth (DDR/FSB:5/6) :--->srill run 200MHz
2/OCed the timming of my DDR SDRAM in DFI nF3 UT BIOS like this :
CPC: 1T
tCL : 2.0
tRCD: 3
tRAS: 7
tRP : 3
tRC : 10
tRFC: 12
tRRD: 2
tWR: 2
tWTR: 1
tRTW: 1
tREF: 3120
tWCL: 1

everything elses of timming I set at Auto (no change). Vdimm at stock
this passed the OCCT Stability test,...

Is my RAM timming OK ??
I wonder if I can OC the bandwidth more from 200 MHz ??

Thx for your advice...

@ 200(1:1) : crashnwhen enter window
@ 180(9/10): can't pass the OCCT test

After taking risk by adding the vdimm to get 220 MHz at 2.7 V

WOW...I could even pass the OCCT test
... but that was the last time I saw my windows XP because on the next restart I got nothing else except black screen (OS didn't boot )!!!!!


ofcourse when I tried 240 MHz by 1:1 divider ----> worse result, BSOD !!!

please help !!!!!
