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!

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.

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

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?

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.
