i7 3930k 64GB Corsair @ 2133

post #1 of 3
Thread Starter 
Hey all, I am running a i7 3930k, msi big bang xpower ii, 64GB vengance 1866 quad, Gtx titan SLI, ax1200. I am running 4 screens. 3 27" 1080p @144Hz. I want to sit at a stable low latency 2133 with 4.5GHz but I am having such a hard time getting my memory to 1866 mhz.

It will work with 1333 default and 1600 with 9-10-9-27 2t timing. I tried 9-11-10-28 2t, xmp, my cpu is 45 multiplier and 1.35 vcore(to try to get the ram working). I tried putting ram v up to 1.65 (was told by corsair). I read that BLCK correlates to the speed of your RAM. Should I increase my BLCK? If I increase my BLCK should I decrease my multiplier and vcore?

Ive probably reset my pc 200 times trying to get this to work. It never POSTs at 1866 and always fails. Does anyone have any ideas? My cpu is sitting 22c idle and 35c load. Thanks alot everyone!

What settings do you have for vtt and vccsa? Also what about llc?

VTT and VCCSA should be set at around 1.1 - 1.2. DO NOT exceeed 1.2v for either VTT or VCCSA.

LLC's should be set to 130. I am not too familiar with all the bios setting for MSI boards, but I am pretty sure there is a guide on here somewhere.

In my expereince, 3930k's are sensitive to large amounts of ram and have a hard time being stable with large overclock on both cpu and ram.

Yeah, I think they only officially support up to 1600MHz now. I have 64GB at 1600MHz (XMP) and it runs fine on my board. I haven't tried pushing it higher (even though the RAM I have is somewhat made to), because I haven't really had the need to. 37.6GB/s RAM speed (measured with the "winsat mem" test) is good enough for me. thumb.gif

But yeah, with larger amounts of RAM at higher speeds, people have run into difficulty getting them to work.
