I will try your 3800/1900 MHz settings (your Pic ZenTimmings 1.04 - pages back). Need some some inspirations in you complete Asus UEFI settings.

I know the Settings RTT Settings etc. for 4 DIMMs are different to your 2 DIMMs, but the rest should work for me too (Main Settings for CPU and Board etc.).

Not many people use the GSkill 3600C15 today and there are some "special" Settings for the F4-3600C15-8GTZ etc.

Maybe you see some false settings in my pic and give advise to get this faster/stable.


My current settings - yours bellow :
Well I leave the resistances on Auto so I can't shed any light there, but one thing I always do is leave tRDWR and tWRRD on Auto as the board sets those differently per channel. You won't see that while in Windows, but if you look at them in BIOS you'll see them set to something like 10/1 on one channel and 9/1 on the other channel when set to Auto.


Something else I've been doing lately is setting all primaries higher so that I can go lower on tRFC. At 14-15-14-14-30-44 I couldn't go lower than 310 on tFRC, however, with 16-16-16-16-34-50 I have been able to run 250 on tRFC and that seems to do better. I haven't tested overnight yet but it seems promising.
