OK so both sticks fine in single means Imc can't drive two sticks in dual to 3200Mhz.. Imc issue.

There are 4 sticks in total which would run as quad channel.
3rd stick definitely good. Will test the last one now. If all 4 are good, I assume it's either the IMC as we suspect or a dodgy slot on the motherboard. I'll give slots 1A/B/C/D a go instead.

...and module 4 is good too. Looks like I'll be knocking the timings back or the frequency in order to get quad channel stable.

Remember Ryzen has dual channel controller so even four sticks only run in dual. Threadripper has quad so 4 sticks on that are running quad if all placed in the correct slots.
You can try higher timings or lower frequency exactly as you suggest. It's clearly an Imc issue this or cache limit.

Dropped frequency to 3066 and all seems good. Begs the question is 3066 at these timings superior to 3200 at looser timings.

My opinion was that higher frequencies were superior to tighter timings since the "Infinity Fabric" is tied to memory frequency but obviously I was wrong. Have a looksy here: https://community.amd.com/community...emory-oc-showdown-frequency-vs-memory-timings

Depends on timings used.

I run tRC at 52 @ 3333MHz 14-14-14-30 1T stock volts. Ran it in the low 40's when at 3200.

Test the timings on your applications some stuff it can help quite abit.

Bizarrely, my board appears to have reset the memory back to 3200 at some point during my reinstall of windows 10 and it's proven rock solid since. I've dropped tRC to 52 and it seems stable but there has been no noticeable difference from doing so.

You need to run benches to test the differences.
Yeah, I had a tinker last night. Mine didn't like 3333, but likewise, my 1700 won't go above 3.8. Very happy with the sticks however - they do exactly what it says on the tin, unlike other brands. Straight in at 3200, with ultra low CAS.
Soldato
I had to up my SOC voltage and set ProcODT to 60 Ohms to get 3333 stable on my 1700. So there is hope for you yet.

Good to hear more positive feedback for these kits.
One of the best plug and play solution for Ryzen on the market for sure.

Got mine arriving today (Team Group Dark Pro "8Pack Edition" 16GB (2x8GB) DDR4 PC4-25600C14 3200MHz Dual Channel Kit) to replace my Team Group Vulcan T-Force 16GB (2x8GB) DDR4 PC4-24000C16 3000MHz Dual Channel Kit which I couldn't get to post over 2666MHz.
Checked out your ASRock AB350 Pro4 stats so I should be able to get the new ram to run at 3200MHz @ 1.2v?

Set xmp and done. 1.35v xmp. I tested that board very very easy if Imc can handle ofcourse but 90% can.
3333Mhz should also be fine adjust ram divider upwards one notch and xmp.
