Asrock X79 Fatal1ty Champion 32GB RAM at 2133Mhz unstable

[Chrono Detector]

I just bought the Asrock X79 Fatal1ty Champion board and I have one issue with it. I have populated all the DIMM slots with 4GB sticks, a total of 32GB of RAM and they are rated at 1.65V, 2133Mhz. However, I cannot get 2133Mhz working properly, booting into Windows will BSOD within a minute. Is it possible to get 2133Mhz stable with 32GB of RAM with all RAM slots populated or not?

Perhaps you should change your voltage as describe at the bottom in this two articles G.Skill RipjawsX F3-2133C9-32GXH 32 GB PC3-17000 1.6 V DDR3 Review | techPowerUp and Patriot Viper Extreme PC3-16000 CL9 1.65 V DDR3 Review | techPowerUp

I have this board too, it works like a charm. But you have to put manually the voltage required for your oc, and the level 3 or up to ensure stability. Those memos need 1.65v at least...

I'm not overclocking my CPU, installing 4 sticks will run 2133Mhz fine, but 8 sticks will BSOD unless if I set it to a lower frequency. What kind of voltages do I need to increase in order to achieve stability for all 8 RAM sticks at 2133Mhz?

Have you tried xmp profile? It should work fine. If that does not work, try increasing vtt voltage to 1.22-1.25.

Try to put vcore offset and a gain of 0.04-0.06. Enable auto increase in turbo.

I have seen with my four sticks that xmp applies the total correct values. If I put them manually, I have unstability. Increase those voltages too. It should do the trick.
