Hello all, first post here.
I recently brought some F4-4000C17D-32 Royal Silver ready for my Zen3 at the end of the year. Really nice memory.
I have since been able to push my 2600x to 1700MHz "FCLK" (3400MT/s) and verify stability and error free using this kit.
Now I am trying for 3600MT/s. I realise this is quite high for a Zen+ (2000) CPU but i have managed to get it to boot and into Windows where with my previous attempts i have not been able to even POST the system at this speed.
I suppose i should go into my current settings and what iv tried so far.
SPEC:
Asus ROG X470-F "gaming" mainboard.
R5 2600x on 240AIO
2x16GB Dual Rank F4-4000C17D Royal Silver (With RGB on dur!)
650w Corsair PSU (80+bronze)
Gigabyte RTX 2080Super
M.2 NVMe & Sata SSDs
Eleventeen-thousand system fans!
Picture1 is of my 3400 timings and settings. (See attachment)
Here is what DRAM calc reccomends for me @3600 (See attachment)
But i have to run a combination of the reccomended and a mix of my 2400 loser timings to get it to boot.
I guess this post is getting long now so I will leave it at that for now.
I am looking for some reccomendations on what to try to get stability and things i have not though of.
Thanks in advance for reading the post and if you have anything to contribute I appreciate it.
Cheers, SPAWN

- I am running an all core OC of 4.2GHz @ 1.450v with LLC4 and droops to 1.444v under load (CB20) - so i can't (not willing to) really push that voltage any more - Temps reach about 75c peak and settle about 71 in a CB20 run (150watts 90amps ~ish)
- SoC Voltage is 1.069v and does not seem to droop with any load. I have tried this voltage all the way up to 1.225v but it caused memory errors when too high (LLC4) [do i need droop on SoC?]
- DIGI+ Power settings are pretty maXXed out 140% current capability etc 450-500KHz switching freq
- Altering the on die termination (ProcODT) above or below 68.6OHM causes it not to boot (at 3400*)
- Altering RttPark from Q/1 (240ohm) causes it not to boot*
- Disabling GearDown causes it not to boot.* [I hear ClkDrvStr @ 120ohm can help this?]
- I have tried various DrvStr combinations 20,20,20,20 - 24,20,20,24 - 24,30,20,24 etc. and 24,20,20,24 seems best*
