just set up my RAID-0 array with 4x 970 Pro 1TB and the benchmarks are crazy (not real world performance though):

OC voltages and settings for your CPU, Cache, VIN, VCCSA, etc are similar to X299 settings eg you can use 7980XE voltages for reference. I am running W-3175X at 4.6 on few cores down to 4.0 on all cores on Asus Dominus Extreme. It just gets too hot and CPU is on EK block with 480+360mm rads. Had a lot of memory detection issues until I went for the EK block. The socket mounting design is very bad.

Interesting... I got the G-Skill Trident Z Royal @ 4000Mhz (96GB) and they worked fine out of the box - no issues at all. Returned the Corsair Doms.

Yes, I think I will have to do custom loop as the CPU is insanely hot even at idle (~ 50C). I do have to say though that the EVGA SR-3 is an absolute beast.

Can you share your 7980Xe settings? What CPU, Cache, VIN, VCCSA etc. are you using?

Also, what are you benchmark scores like (just for comparison)?

My Cinebench R20 run at 4.50Ghz is:

It's been a while when I last checked my settings due to a new job, but some notes from my memory.

Voltages depend on each CPU but I have 7800X, 9900X, 7980XE and W-3175X and each of them share roughly same characteristics when overclocking. My 7800X is the best which can do even Prime95 5.0 GHz, 9900X is the worst not stable past 4.6.

Core: Baseline for all of them is 4.5 GHz and it would take between 1.15~1.22V to reach those clocks for core. You just have to test. I use Prime95 with AVX disabled but you can use whatever you wish for stability testing. W-3175X seems to take around 1.2 V for 4.5 so it's not a very good CPU. To run CB at 4.6 I need already 1.24V.

Cache: For my CPUs 3000 MHz on the cache seems to be between 1.075~1.12V. On 7980XE/R6E combo to get 1.112V for cache it is +175mV on offset voltage and for W-3175X/Dominus this for some reason is +200mV. Measured with multimeter from the boards directly. Cache seems to be the one causing most of any weird behavior together with memory settings, often it is not even the core voltage acting up.

Input voltage: Use between 1.7-1.9V, and adjust the LLC to keep it stable. I think you should need to stay at least at 1.65V under load, preferably closer to 1.8V for heavy load. LLC doesn't affect core voltage, only input voltage. I've read some try to shoot this one as low as they can to gain some thermal headroom, but if you go too low you can see worse scores eg. in Cinebench or instability.

VCCSA: I actually run VCCSA stock on both platforms and I think it is staying at around 0.9 V. Better to check what your board is giving with XMP.

FOR CB20 I only found an old screenshot for now when I experimented some OCing on a cold day...but if you wish you can check my build log with some screens and pictures from the build on our local forum, if linking is allowed. It is in Finnish though.

Very nice! Checked out your build log (used google translate )! Btw, your screenshot shows 1.784V for 4.7Ghz. Surely that's a wrong reading? That kind of voltage on that CPU would kill it instantly I would think?

I've now dialed in my OC at 4.50Ghz at 1.195V, Cache at 3.1Ghz (but need 1.20V Cache Voltage), and RAM at 4000Mhz but tightened timings to C16 (stock was C19).

Just tried some games out recently and it's an absolute beast - 160fps in BFV in 4K max settings, 140fps in GTA V with a ton of mods also in 4K max settings and ~ 90fps in RDR2 4K max settings (except a couple of settings on High).

The worst part is the air-cooling of the GPUs - I need to get over my apprehension of water-cooling and just do it. I will do it soon. The GPUs are at 88C at load so they thermal throttle quite a bit and I'm definitely losing performance during gaming there.

The CPU cooler is interesting - using the Asetek 690LX-PN but I swapped out the 3x stock fans for 6x Noctua 3000rpm fans - under load in games it barely hits 70C but in Cinebench R15/R20 and other benchmarks, the temps get really high when all 28 cores are at 100% load. Definitely not ideal but I will water-cool the CPU soon as well.

Thanks! I love it so far but I think this system definitely needs proper water-cooling or better.
