Recently, I decided to upgrade my RAM from 2x2GB sticks of DDR3-2000, to 2x4GB sticks of DDR3-2000. I had been running the previous sticks at 1866Mhz and 8-9-8-21 without a problem for quite some time. This is all while my CPU is running at 4.6Ghz at roughly 1.3v.
The new sticks are in, and they are at their stock timings of 9-9-9-24 (for now), and running at 1866Mhz at 1.65v. However, I'm having stability problems with these new sticks installed. I can't seem to get through more than two cycles of Prime95 on blend without a thread crashing. There isn't a blue screen, the Prime95 thread just fails, usually due to a rounding error or something. To make matters a bit more interesting, the sticks pass MemTest without a problem.
When running Small FFTs on Prime95, the CPU seems to do much better. This makes me believe something is up with my IMC, and that running 8GB is starting to strain the poor girl. When I up the VCCIO in hopes of stabilizing my IMC, it seems to crash quicker! I haven't tried moving the VCCIO voltage down yet... but maybe I'll give that a shot after I post this.
Any ideas? Let me know if there is some more information you need.
EDIT:
Just had a 101 BSOD on Small FFT's, bumped up LLC and am running the test again.

I'll have to do some testing to find out if the extra bandwidth from 1866Mhz is worth the loss in latency over 1600Mhz with leaner timings.
