[SOLVED] Will my memory setup with with XMP 2.0?

[nguthrie2]

Hello,

I've recently bought what I had originally thought were a matching pair of RAM sticks to my current ones. (You'll see the hardware revision differences in a moment.)
What my current dilemma is, with XMP enabled, I cannot POST after installing the new RAM. It will POST after replacing the old ones, or just using the old ones, but not all together.
My question is if this can be configured any way to run the XMP profile with all 4 sticks of 8GB RAM? Is it even worth trying to overclock a little with XMP? See specs below:

Any help greatly appreciated!

The risk of buying more then one kit ...
The problem seems to be old/new stick don't have even single common JEDEC profile (with same timings). That's probably why you can't boot with all 4. Did you reset CMOS before putting all 4? The other thingt you can do is start with only old sticks, enable XPM, power off, add new sticks, don't reset CMOS, power on and hope to get lucky. It might work because actually XMP profiles match. But more likely it won't work.

I think the one thing I haven't done yet is reset CMOS by removing, unplugging from wall, then holding power button to discharge all. I can try this and report back.

The other thingt you can do is start with only old sticks, enable XPM, power off, add new sticks, don't reset CMOS, power on and hope to get lucky. It might work because actually XMP profiles match. But more likely it won't work.

As for this one suggestion, technically that's exactly what I did when buying the sticks. I was already running on old RAM sticks, with XMP enabled. Adding the 2 new sticks was what prompted the issue, unfortunately.
