any word on this one?

The memory controller doesn't handle it. The more module capacity (16GB vs 8GB modules), Rank (Dual vs Single), amount of modules (8 vs 4) and total capacity (64 to 128GB), all this increases the load and becomes unstable at higher frequency/speed.
2933 MHz is the highest stable frequency for Threadripper with 64+ GB capacity in either 8x8GB or 4x16GB. Same for 128GB which requires 8x16GB. And this is with the most compatible QVL approved Samsung B-die ram,etc..
So there is no need to waste money buying faster memory because it will not run stable above this frequency.
Sure you can run 4000 if you go with two 4GB modules, but that is scenario outside of our use.
-Threadripper benefits a lot of from fast memory in certain tasks. Corona sadly being one of it from my tests. I would look for memory no lesser than 2666 but not higher than 2933 (3000) as more than that isn't working anyway for four dimms and 64gb capacity.
I tried Rebusfarm and it is very handy , however I was not able to save in CXR corona format.
I don't know if I miss something in the procedure or if it's not allowed that file format saving .
CXR format saving from renderfarm would be very useful to adjust lighting color and intensity after the renderfarm computation and not before .
The only CPUs for the X99 I'd look at are V3 series. You can get a modded bios for most boards, allowing max turbo on all cores. This combined with lower price on the used/QS sample market makes them a much better buy than anything from V4.
Unless maybe it's a render node with two CPUs and you get top V4 for cheap.
As mentioned somewhere before, current top V3 models are 2683v3, 2686v3 and 2696v3. The 2696v3 on a modded board gives better speed than the top model 2699v3.
