The thing with X99 is that a lot of other things can give out bad results in RAM testing. Core, Cache, and VCCSA can all mess up RAM at it's rated speed. Even OS can. So tedious testing will need to be done to prove this.
That being said, I RMAed G.Skill kits due to not passing XMP Profiles before. You can attach a screenshot of the tests you have done for faster response.
The testing I've done is why it would surprise me if the kit is actually good at rated specifications. No Vcore, Vcache, their respective frequencies, the BCLK or strap options, VCCSA, or VDRAM combination will let the RAM pass the rated specifications. You would think I could get tighter timings with no core or cache overclock, but I cannot. This implies the IMC is not at capacity even when the cache is overclocked (and I tested the overclocked cache with AIDA64 per your instructions pages ago for well over 4 hours without problems). So that leaves me with a bad RAM kit, or a CPU that works great for everything, including RAM frequency, but refuses to take tighter RAM timings regardless of frequency. Unfortunately I simply don't have another identical memory kit to test with, so I'll take advantage of the fact that I bought super expensive RAM and get it RMAed if I don't find things are stable with the 3301 BIOS. As far as I'm concerned, G.Skill is well within their right to test the RAM when I send it in and tell me it works and send it back.
Edit: I already emailed them about the issue and was given an RMA form, so I don't think I'll have issues getting an RMA completed.Edited by stargate125645 - 7/28/16 at 4:52pm
