P95 always returns errors as soon as I started it with the following messages "FATAL ERROR: Rounding was 0.5, expected less than 0.4...Hardware failure detected, consult stress.txt file." I have already tried Memtest86+ and Window Memory Diagnostics, one stick, both sticks, without any errors. The only way I can get P95 to run stable is to bump the DRAM voltage a notch to 1.55V. So is this a memory, motherboard, or even a power supply problem? Thanks in advance.
OK - first of all GO BACK TO STOCK - something I outlined quite a bit in my videos, to test for HARDWARE errors.
Once you've gone back to stock, set your timings, voltage and speed of your RATED RAM specs, and see if it passes P95 in 24hrs.
If it doesn't - most likely to be RAM HARDWARE related.
If it PASSES - then it is your OC (not your ram settings) that need to be changed.

What I would do is bring back stock clocks and see if prime95 fails with same as you noted (needs 1.55) . I would test at MB defaults and XMP speeds .
If it still fails I would call Corsair and see what they say .
Also check if others with same memory are having to run 1.55 too .
I have 2 sticks only, and in the video had two sticks.
I still have it at 1.55v - but yes the principle applies as if you have more sticks, it MIGHT be better to give it a few extra volts.
