Hey,
I sent everyone that I saw running this memory kit a PM, if I missed you, it was not intentional.
I was hoping since it appears that our memory is a rare choice for Ryzen that we could use this thread to share notes and help each other out.
I have had some pretty good luck on the Crosshair VI Hero bios 9945, but have struggled to find memory stability above 3466 MT/s.
Here is a list of my stable (at least 200% coverage of all memory in HCI memtest) Memory settings:
CH6 Bios 9945
1800x
2X G.Skill F4-4266C19D-16GTZR (2x8GB single rank)
Bios Settings:
compaired to Bios 0902 and 0081 I have found that I don't need to mess with as many BIOS settings in 9945.
The Fields below are the only fields modified from optimized defaults:
CPU LLC: level 2
DRAM Current limit: 110%
Dram Boot: 1.45v
Proc_ODT: 53.3 (only one that seams to work for me? You?)
CLDO_VDDP: depending on the "Strap"
Vdimm: 1.425v
SOC:" 1.135v
PLL: 1.81
SB: 1.05 entered manually
Core Boost: Disabled
(I think that is it, I will edit anything I forgot in later.)
I also set the failure retries to 5 (forgot name of bios field)
2x8GB sticks:
3200 MT/s
12-12-12-12-28 (All other timings auto)
-or-
14-14-14-14-32 (all other timings auto, vdim 1.35v)

I am working on 4x8GB 3600MT/s now, and will update with any results.
Here is table I made last night with some of my working memory settings and benchmark results, I will make a public google drive table that we all can submit results into:
Please share your settings and results!
