Memory Problem with my Intel X48 and DD3

[zod96]

I've had the X48 board for about 3 weeks now. I am getting lots of cold boots. I have 4 sticks of Gskill memory at 1 gb a piece pc1600 ram. I've run memtest and the sticks are fine. I tried changing the timmings in the bios from auto to 1333/333 and the vdimm from the default 1.5 all the way to 1.9. I changed the timmings from 9-9-9-24 to 7-7-7-18 Nothing seems to work. Once I'm in windows its rock solid no problems no reboots nothing. It just when I turn the computer on, I would say it happens at least 50% of the time I turn the computer on. I'm using the latest bios as well. When I use just 2 sticks it seems fine I haven't had a problem, and I've tried all 4 sticks using just 2 at a time and it was fine. Its only when I have all 4 in that I get these problems. Anyone else having this issue??

did you say PC1600?

Perhaps try bumping the NB voltage up a bit? And changing the timings from 9-9-9-24 to 7-7-7-18 is stressing the RAM even more. Try using the 9-9-9-24 timings while increasing the NB voltage a little, probably by 0.05V.
