CM2X2G6400C5B4 RAM Upgrade BSOD on Windows 7

HI there,

I have currently 2 X CM2X2048 - 6400C5 (ver 3.1) sticks of RAM in my machine. I bought 2 x CM2X2G6400C5B4 (ver5.1) sticks to bring my RAM up to 8Gig. Since I installed the extra RAM I am getting random BSODs (kernel power) I contacted my seller and theuy suggested upping the NB voltage to 1.2 and DRAM voltage up to 1.9v. However, I am still getting BSODs. I have taken the extra RAM out of my system and it is stable again. Have you any suggestions as to what I can do to run 8Gig stable. I am a newbie when it comes to RAM. I have updated all drivers and BIOS but I am still having problems. BTW when I install the new RAM should it be in slots 2 and 4? the existing RAM is in slot 1 and 3. A1 tweaker on the ASUS 5PQ has LOTS of settings, where do I start? Many thanks

Yellowbeard thanks for the prompt response. I've upped the NB to 1.3 and my Dram is at 2.0v. However in CPU-Z the RAM is showing at 1.8v and the Vcore is at 1.15v (my timings are 400.4MHz, fsb:DRAM 2:3,CL=5,tRCD=5,tRP=5,tRAS=18, tRFC=60 and CR=2T). From your original reply you said I might have to drop the memory back to DDR667 is this because the extra RAM modules are not compatible with the originals? They were sold to me as being compatible. Also, if I have to go back to 667 can you give me a walk through? or should I just send the memory back. All I want is 8Gig to work in the machine. Thanks for your help so far.

 

UPDATE: I just posted this and went to open a new browser window and I had a BSOD.
