I bought this RAM before the 3900x was released, simply because it was a crazy deal (almost half the price it is listed at now)
SKU CMT64GX4M4C3466C16 DOMINATOR® PLATINUM RGB 64GB (4 x 16GB) DDR4 DRAM 3466MHz C16 Memory Kit
Once the XTREME was released I discovered the memory above was not on the QVL list (2x16GB of this kit is on the list, but 4x16GB is not validated) - OK I thought, QVL is just for the memory profile, I can probably manually tune it to work (I'm currently on BIOS F12e).
Since then the memory profile has 'kinda' worked in that it will sometimes train and lock in, then at some point (usually If I went into the BIOS which then triggers a re-learn) it will lose the memory profile and it will default to SPD. I'd like to think that this shows the rated speed is possible with 4x16GB, I just need to discover what settings help it stay locked in.
Ideally I'd like to be able to achieve 4x16GB 3600, but I'd first like to achieve stable settings with the rated speed.
I'm not sure which variables I should be playing with (starting with the recommend columns in DRAM Calculator for Ryzen 1.7.3) - Would increasing the SOC voltage up to the max of 1.1v affect this the most since its more about getting the memory controller stable with 4x 3466/3600 double sided DIMMS?
As a side note, having the memory profile active or static memory overclock can trigger my Sound Blaster ZXR to disappear as an audio device in windows (sometimes its fine, other times its not). When the memory resets to SPD the ZXR has no issues. Any ideas on this one? I know sound cards have had their fair share of problems with this chipset.
