What I would do is save your current setup as a profile within Tools > ASUS User Profiles . This way you can go back to something stable when you need it.
Then save it within a second position as well, name this your "base OC profile" or whatever you think is right. Makes changes below/save and work on profile.
Within this base profile I would leave:-
Trcpage [Auto]
Trfc2 [Auto]
Trfc4 [Auto]
Trdwr [Auto]
Tcke [Auto]
Next I'd set manually:-
TrdrdScl [2]
TwrwrScl [2]
TwrwrSc [1]
TwrwrSd [7]
TwrwrDd [7]
TrdrdSc [1]
TrdrdSd [5]
TrdrdDd [5]
The timings with [7] [5] I would only lower once you have reigned in other timings, all the way up to 3466MHz you should be sound with setup IMO. The timings with [2] you can slacken to gain some stability, but be aware they give best performance gains.
Set Tcwl equal to CAS, if using odd CAS set Tcwl to CAS - 1, as odd Tcwl hasn't worked at frequencies I have used. For odd CAS to not be rounded up to nearest even Gear Down Mode must be [Disabled]. I'd also set Power Down Enable as [Disabled].
I always gun for Cmd2T [1T], but you may find 2T helps you stability wise. If you do use gear down mode then leave Cmd2T setting on [Auto].
Trtp you should be able to snag 8 to 10, I even have it as 5 on one rig. You should be able to just keep changing this independently of other settings IIRC.
You should be able to use
TrrdS [6]
TrrdL [9]
TwtrS [4]
TwtrL [12]
If need be just slacken these by a notch each. Once later profile is sound you may gain a notch or two lower on these.
Start Tfaw at [36], later lower if you can (ref the rule in link). Start Twr at [12], you may gain it as 10, I have one rig set this way, slacken a notch or two from 12 to improve stability. Start Trfc at [400], with only giving VDIMM 1.35V to 2 differing sets of G.Skill, I can have this as 274 for 3400MHz/3466MHz.
You may be able to use all the way upto 3466MHz :-
DRAM CAS# Latency [15]
DRAM RAS# to CAS# Read Delay [15]
DRAM RAS# to CAS# Write Delay [15]
DRAM RAS# PRE Time [15]
Start at a lower frequency like 3200MHz, be systematic in changes, keep notes.
It can seem daunting to initially setup your own timings, but once you tinker a little a few times it becomes easier IMO.
