Getting massive frame drops in Metro Awakening due to timing jumps on my Kingston HyperX DDR3 1866?

The screen tearing when turning quickly was unbearable, and in VR, it was a straight-up disaster for my stomach. Looking at the logs, the Kingston HyperX Fury DDR3 1866 was having a meltdown with the memory controller voltage jumping between 1.5V and 1.6V, causing frame times to spike between 25 - 42 ms. I tried bumping the virtual memory to 16 GB, but that just created a disk I/O conflict and made the stuttering even worse, which was incredibly frustrating. I went back into the BIOS and manually locked the DRAM voltage at 1.65V, while tightening the primary timings from 10-10-10-30 to 9-11-11-28. AIDA64 showed the read latency dropping from 88 ns to about 72 - 76 ns. I had a couple of random reboots at first, but bumping the SoC voltage to 1.1V stabilized everything. Memory temps are sitting at 45 - 52℃ and it's rock steady now.
