im using this ram
cmxg4gx3m2a1600c9
everytime i try to increase the volt to 1.65v and above my pc will hang/bsod
using x.m.p got the same results
any idea why?

well, followed the xmp profile timing and voltage somehow ended up with bsod(which only came out once), and pc freeze
manually decreasing the voltage but still keeping the timing and frequency at 800MHz somehow ended up stable, im just kinda confused
using asus p8p67 btw

The problem with XMP is that sometimes it tends to alter something else (i.e: BCLK value, VTT voltages and so on) which might led to instability...

What you should probably do is set the ram speed manually to 1600mhz and set the main timing and the CR to 2t, while everything else in at stock values...

Tried that and still gets pc freeze
The funny thing is after I manually set the main timing and speed as long as I don't set the volt over 1.65 and above it will be stable, I'm puzzled now

have you done stress test?

5 minutes into stress test pc freeze whenever i set to 1600mhz sweat.gif with all those main timings and voltage manually set
so now is it the RAM problem, or is my pc?

hard to say. if you near me, maybe i can test them on my rig

hmm my mem test got no error but only 2 passes then i give up
but something unexpected came up, my b1 and b2 slots when testing with single module primary timing were 6-6-6-20 instead of 9-9-9-24 which i set on the bios

wow very tight timing there.. 6-6-6 at what speed
*
thats the weird part, set at 1600Mhz
gonna try wat happened when i set it at 1333Mhz now on bios and test it at mem test
since 1333Mhz is the stable 1 with 6 hours stress test

okie im not sure is it bug on memtest
but when i login to windows cpuz indicates the timing were 9-9-9-24

this only happens if i put the ram on either b1 or b2 slot for asus p8p67
the cas timing were at 9-9-9-24 on the mem test when its at a2 slot, din bother to try out a1 since my cpu fan is blocking it

okie i think its safe to assume is my MB problem
running stress test using 1 ram on b2 slot causes the pc freeze in 5 minutes, same like when i tried it in dual channel
putting the same 1 ram on a2 slot n ran a stress test can goes more than 1 hour, i dont bother to continue since if it goes pass 10 minutes it beats the best record already doh.gif
