You have a multimeter dont you? hook up the Probe it leads to the board. Dont trust the bios or the software.

Are you noticing this only with the Memory set to XMP?

I have the Corsair 1600mhz Cas 8 Kit but i'm running custome settings. No particular profile. VTT is 1.36 on the multimeter.

I measured everything with a DMM. I mentioned it in the post above. So far all of my test have been with X.M.P. first and then OC, but I cannot see this making a difference. All X.M.P. does is set some timings and voltages. I will test without X.M.P. and post back as well. My current memory settings are as follows...

X.M.P. Profile #1 (only profile), OC to 1804MHz, 8-8-8-24-2T, 1.65V DRAM, 1.35V QPI/DRAM (measured high at 1.46V, boots okay for the first 5-10 seconds at 1.37V measured). Same thing happens at 1600MHz as well (default for X.M.P. profile). Error free in all memory stress tests.

In the meantime, you say you are measuring 1.36V, so I have a couple of questions.

1. What are you running your memory at (speed, voltages including QPI/DRAM)?
2. Are you using X.M.P. profile?
3. Do you experience missing memory channels?
4. Do you experience cold boot issues?
