Well 3466 ended up not stable after all after a few days of non-stop crunching. Found the computer had rebooted somewhere along the line and the memory had fallen back to 2133 JEDEC safe speeds.
So back to 3400 Fast which is where I know it will run stable for months. It is a pain in the butt to get there if you remove power however. Have to go up in steps in retraining from start from 2133, then XMP etc. etc. Can't just bang it straight up to 3400. I still haven't found the ProcODT value that survives a power removed cold start.

I am starting to suffer from only having 16GB of RAM. I want to upgrade it, but there doesn't seem to be any good price/performance deals out there on the used market, since you need 4 dimms minimum for threadripper.
But then I started looking at ECC memory. Does anyone here have experience with that? Supposedly it's really nice to overclock ECC memory, since it doesn't crash on errors
Overclocking ECC sure is nice though, none of this mystery crashing **** or wondering if any of your stuff is getting corrupted and saved to disk. Going to run at 2400 for a couple days just to make sure its not junk and then ramp up through bins to find what the real limit is, probably test 2933 next. https://hardforum.com/threads/x399-m...hread.1940840/
Should I go for 4x32GB?

I stepped back down to 3333 and went with further tightening subtimings. It gives me more memory performance compared to 3400 and the unstable 3466.
It's really funny to look back at early 2019 OC results on the left, and the 2020 OC on the right

|Keith Myers||Took a lot of effort with many failed boots, but I finally managed to get my 2920X to retrain at 3466 CL14 and that survives repeated reboots with the 390 BIOS. It is stable too for my distributed computing load.|

|dalathegreat||Started to retune with the latest 3.90 bios. Previously been running 3333mhz due to random hickups with 3400mhz. Now 3400 seems attainable, and I can even boot with 3466. Quite amazing for a first gen ryzen CPU!|

Finally got around to updating my Fatality to 3.80 BIOS. Managed to kick the memory up to 3466 CL14 from 3400 which always crapped out before on the earlier BIOS. But locked the board up solid when I attempted to go to 3600. Had to reflash the BIOS and start over. The Zen+ silicon just doesn't have the IMC capable of 3600 which comes so easily to the Zen 2 IMC.
I also decided to go the manual overclock route in preparation for the better cpu block I hope to get soon. Locked all cores at 4150Mhz instead of letting Performance Boost Override try to ride herd on my cores. Best they would average under load was around 4050 letting the cpu and board try to handle the overclocking.
I already am seeing the benefit of each core locking to 4150 while the task running on it completes with a steady clock that doesn't vary. The times are coming down. The jump to 3466 helped also, while the latency didn't make that big a drop, I do see much better memory throughput numbers.
Also manually overclocking lets me drop 50mV off the Vcore that Auto would set. The temps are 5-8° C. lower now. Just what I expected and why I think with the better Optimus block I ordered probably will let me get to 4200 or maybe even 4300.

|davidkozat||managed to get to 3400mhz on my quad channel sticks that wouldnt even run at 3000 for 2 years the Dram Calculator helped me out and oh boy that OCing your RAM make a big difference to performance and responsiveness. Went from 2933 to 3400 on my 64GB 3200mhz and am not even on the latest BIOS.|

|dalathegreat||I updated to the 3.90 BIOS two days ago, no issues with the same overclock as before. I will try to push it even higher now, but who knows what "Improve CPU power settings" even is supposed to do.|

|MethMouth||After updating my fatal1ty to 3.80 my 2950x locks the boost to 3.9 and forces all cores to do so even not all individual cores are being used so I downgraded back to 3.70 since I don't know enough to go through these millions of bios options to see what is causing that.|

3.90 2020/1/8 Improve CPU power settings.
Mine was a 3.80 version release of the same date. Will give it a try later. Haven't felt the need to update from 3.60 BIOS as the 3.70 BIOS fix was for a problem I don't have.
Asrock is as terse in BIOS description improvements as ASUS.
