Testing the GSkill DDR4 kit F4-3600C17D-32GTZ ( 17-19-19-39 )1.35V kit on 5700X3D and have achieved the results in pic. It does 3600 16-16-16-36 without voltage change.

Not sure if I should expect better from this Bdie kit, despite being one of the worse bins, or this is good enough for 3800 with 5700X3D. Was hoping for a sub-60ns latency since I have seen that mentioned in many old posts that come up in searches.

Errors with:

tRCDRD 16 ( is 17 getting rounded to 18 with GDM on? )

SCLs 2

tWTRL  8

Does not boot with:

tCL 14( even at 3600 at 1.45V )

tWRWRSD to 4 

tRDWR 8

GDM off

Concerns : tRRDL 4 and tRTP 6 are lower than I have seen others do with single-rank kits. So doubtful of them, but I have not got any errors in memory tests.

Have not touched the ODTs/RTTs/Drives at all, they are all on Auto.
