Problem when overclocking

post #1 of 2
Thread Starter 
My memory capacity will decrease when I overclock. This is very puzzling to me and I'm not sure why it is happening. PC Specs:

-i7 5820K
-X99 Deluxe U3.1
-EVGA 750 Watt PSU
-980 Ti
-16GB Corsair DDR4 (4x4GB)

I firsted started having troubles when my PC spontaneously refused to startup. I removed all but one memory chip and the PC would boot. It appeared as if only one memory chip was good enough to boot to (but failed integrity checks according to Memtest). I had my PC overclocked to ~4.3Ghz on air cooling right before this (diagnostics were all performed at stock clock speeds). I went and bought new Corsair memory modules thinking my DRAM modules were the culprit. My PC did nearly the same exact thing. It would only boot with one slot occupied, and fail Memtest. As a last resort, I flashed the bios to the latest revision. I hesitated to do this initially because, I had previously flashed it to the newest revision, and lost 4GB of memory in the process (or so BIOS reported). Once I flashed back, I got all of my memory back. This time, with the newest BIOS revision, I got all my memory back and they all pass Memtest. The problem is, even if I overclock to just 4Ghz, BIOS displays that I only have 12GB. If I reset AI Tuner to normal clock speeds, my memory comes back.

Since Intel CPUs have an on-die memory controller, is this the culprit? Is my motherboard bad? Are these DRAM modules incompatable? Is this a known bug? Please advise (and thank you for your time).

Have you tried manually setting the clock speeds and CAS timings for your ram?
