Help with XMP Profile

post #1 of 2
Thread Starter 
I cannot get my system stable with the default XMP profile that my "G.SKILL Ripjaws 4 Series 64GB (8 x 8GB) 288-Pin DDR4 SDRAM DDR4 2800" came with. I am running this in a Rampage V Extreme with a 5960X Processor. Any attempts lead to system instability that requires a cold boot CMOS reset to get out of(Whether or not I am in the OS). Am I missing something here? Any ideas? It runs fine when left on auto, but I would like to have the memory running what it is rated at, or find the issue that is causing this. The system is not overclocked, (besides what I am attempting to do with the XMP profile of course). I ran the extended test with windows memory diagnostics tools and it found no errors aswell.

Yea. You're overtaxing the memory controller with all that memory.

XMP profiles are just a memory manufacturer's guess at settings that will work with most typical memory configurations in most typical computers. Neither of which you have. Remember, XMP profiles are programmed on the sticks, not the computer, and one stick doesn't even know if there are any others, much less how many. I stray as far away from XMP as I can get!
I've done lot of memory overclocking, but never with that much memory so I have no idea what to change, just what the problem probably is.

Is there some particular reason why you need 64 Gigs of memory?
It's pretty hard to overtax 8 gigs, much less 16 unless you're doing something weird.
