Scrap that, it's actually Hynix. I thought they used Samsung, i checked before i bought. Just loaded up AIDA and can see it's Hynix. Balls.

AMD RYZEN 1800x @3.90 mem@2133 vs AMD RYZEN 1800x @3.6 - @3.7 (XFR) mem@2133 vs AMD RYZEN 1800x @3.6 - @3.7 (XFR) mem@2666
AMD RYZEN 1800x @3.90 mem@2133 - Cinebench = 1524
AMD RYZEN 1800x @3.6 - @3.7 (XFR) mem@2400 - Cinebench = 1492

for 3.9 I had it at 1.32 in bios but in windows in HWinfo it never seemed to go over 1.308

Couple of things:
1. Temperature readings on 0902 and pre 5803. We tweaked it a bit too far and will be reversed in future updates, you can manually go back to stock/5803 behavior by going to Tweaker's paradise and set Sense MI skew = Enabled and Sense MI offset = 272 (0902 setting when overclocked is 283). Reading too low can affect your DRAM stability, so if your system is reading less than 30*C I suggest you set it.
2. DRAM settings, we changed to 2T when 2666 or higher ratio is used because of compability and helping some sticks work on the board. Unfortunately we can't set it dynamically or have an option for it until AMD gives us an update. I think overall it should be better for all, if you want to keep 1T you can use 2400 or lower DRAM Ratio + increase REFCLK (140-145 with 2400 DRAM Ratio is a sweet spot).
3. We're aware fan control has a lot of issues at the moment, I'll let you know when we have a fix for it.
Let me know if there's anything else serious that I missed, you guys are busy
We haven't seen many USB issues when pushing REFCLK except when going 145MHz+, perhaps you could try different USB ports from CPU or Promontory?
2x16GB DS most likely with future BIOS updates.
The source is credible. The option would have been to not have any boards at launch, don't think that would have made anyone happier.
I recommend everyone try this! I'll post some screenshots to share my settings, but it is explained in a few posts on oc.net in this thread. http://www.overclock.net/t/1624603/rog-crosshair-vi-overclocking-thread/1320
Good work!I did it, finally i got 4Ghz @ 3200Mhz CL14 stable.
Play that track!
30 minutes of memtest with 16 instances, nay bother. 30 minutes of Real Bench 16GB, nay bother. I made several changes. Firstly i overclocked via P State 0 rather than adjusting base clock frequency. Second i increase CPU SOC voltage a lot to 1.175v, thirdly i bumped DRAM voltage to 1.4. I'm going to tweak those voltages down and find out if either are responsible for me passing the test, I'll start with CPU SOC as i don't like it that high long term.
According to that post above, Crosshair temps are reading incorrectly. I made the change suggested above and my CPU temps have gone up by around 15c+. It also mentions that failing to make this tweak may impact DRAM stability, could this explain why after changing it i can get 3200MHZ CL14 stable @ 4Ghz?
Previously i was overclocking the base clock and the memory. It appears that doing it that way means i can't get my memory stable. However there is an option to overclock the AMD CPU P States, and if you overclock this way, you can get your CPU downclocking and volting at idle, but still overclock to whatever frequency you desire. Check out my HWINFO clock speed stats!
