Just wanted to update on how well this motherboard is running. I've been full load for weeks, not a single hickup even with soo tight timings. Never seen stability like this!

Hoping a new BIOS will come soon, I've got the tuning itch

Why the urge to possibly break things if the computer is running so well? Ha ha. I agree this motherboard is fantastic. Rock stable as a workstation motherboard should be.

Although, if they allow OCing on the Epyc systems, waiting for 2020 with potentially DDR5 on server systems may make me consider a 1P Asrock rack board. But that is if AMD does the 1P Epyc CPUs at the $500 delta they currently are at and hoping the server boards beef up the VRM on them as well.

But, we will see. And at least it won't be like Intel's TDP lie which pulls WAY more watts than marked. Here's hoping the 32 core power draw is really good.
This is a bit weird, even OCd TR 1950x drawing 300W is not heating up the VRM in any way with my LC - Seeing top 35 C with long full load. It gets that way with PBO engaged on P3.30.
Maybe your cooling is broken, bad contact or air in water block?

You are possibly looking at the wrong temperatures. The VRMs on mine (and on all that I've seen here) are around 80C-90C under load (which is completely normal temps for a power draw of almost 370W). Mine is running at 4GHz with a monoblock and 3x 360mm rads.

There are no wrong temperatures when all 4 Mainboard sensors show < 50 C (Tdie included) during power virus loads, with temperature on VRM dominated by the fact that it's right *after* CPU in loop. All 4 motherboard sensors show around 40 C in that hard load. (This being HeavyLoad CPU + Furmark on fullscreen.)
I take it the hottest sensor is VRM, the others are near room temperature. I have the other VRMs and SOC also watered. And 4 ECC overclocked RAM sticks, Vega 64 and Vega FE overclocked GPUs and 2 M.4 SSDs. There's no component relying on passive cooling that emits any notable heat.

My cooling solution is a bit overkill to remove around 1.4 kW according to my power meter (during power virus loads), 1/3 from CPU, 2/3 from dual GPUs, quad D5 PWM pump at low RPM (60W), MORA 420 Pro with 4 Noctua A20 PWM fans.
VRM block is a custom cut piece of kit made from Watercool's Micro SW-X DIY block, attached with Thermal Grizzly Kryonaut and/or Alphacool Eisbach 11W/(m*K) pads where applicable. CPU likewise on Watercool Heatkiller x3 TR4 block. SOC is using generic Watercool mainboard block, secondary VRM and 10GbE are using some Watercool ASUS mainboard VRM block with hacky attachment. RAM blocks are 2x Alphacool's x4 block - only ones that work right with high sticks - and SSD blocks are by Bykski. 2 pumps run under a serial Alphacool Eisbecher Dual D5 top, 2 run inside serial EK X-TOP Dual. And there's an EK X-RES 3 300mm reservoir.

It's very easy to get trapped air in a monoblock that's at the top of your loop. My recommendation is to flow water bottom up and if pressure is low, reorder loop so that hot components and only them are before radiator, everything else on return path. (Yes, I've put a lot of work into that huge experimental loop.) Flowing water top down tends to flow over bubbles regardless of pressures.

Seriously, I got your temperatures with unfanned originally heatsinked VRMs on my Fatal1ty. Fan right above dropped them to somewhere near 70 C. That's with old overclock similar to yours (flat 4.1 GHz at 1.4V as opposed to letting PBO do magic) - mine is higher now, the low temperatures allow lower voltage and PBO tuning from P3.30 allows really high boost clocks. (I've seen 5.1 GHz when it was 4 core load.)

So, going flat 4.15 GHz at insane voltage settings (1.56 Vpackage - 1.615 Vcore), HWINFO says 475W on CPU cores, VRM says slightly more at 490W. I believe that's true, wall socket says 680W on pure CPU load.
Then it goes 88.5 C on Tdie in power virus load and VRM (Loop) go 75 C. The whole machine eats 1.7 kW with added Furmark pushing the limits of the Corsair 1600 AXi I have. (But I have a second, fanless PSU just in case. It can take one of the GPUs.) After longer time it starts to throttle due to overtemperature.

I really do not want to run my 1950x on such nasty overvolt and Tdie though for any prolonged time, but that says something about capabilities of my cooling and why your VRM cooling solution is busted. No, I do not have a chiller. (28 C ambient, it's warm today.)

Well, if you weren't being absurd with the "it must be something wrong with your loop," you could have found out I run [email protected] stable, have 3x480s, and am using Koolance universal blocks. If I was running 4.05-4.1, my VRM stay icy!

Happy to see new traffic in this thread. Got me interested to look at my VRM temps. I run Linux so monitoring capabilities limited to the NCT6775 SIO chip driver. I hadn't bothered to identify which of the sensors outputs was the VRM, so I did a sanity check with my IR temp heat gun. 43.5 ° C. so AUXTIN2 matched up and it was listed as a thermistor temp so I believe it is the correct one.

I replaced the thermal pads on both the PCH and VRM's when I got the duff donated Asrock X399 FatPro Gaming board for my latest BOINC cruncher. Did the same thing on the duff, donated ASUS X99-E-10G WS workstation mobo I was given. Had leftover FujiPoly material to use.

I have a 120 mm fan sitting in front of the motherboard blowing over the memory first and then on to the VRM's. Don't think VRM temps are an issue for me. Sitting right under 68° C. Tdie temp when running at 4150Mhz with Level 2 PBO and the Vcore on Auto at 1.34-1.38V when under BOINC load. Memory is at 3400 CL14 Fast timings.

Twin 360mm radiator loops, one for the cpu which is using the XSPC Raystorm Pro Neo Threadripper block and the other loop for the RTX 2080 and GTX 1080Ti with two 1070 reference blower cards sandwiched between them.

Anyone have voltage suggestions for a 1920x running at stock clocks on an X399M Taichi? Just got this running last night and am prioritizing cooler temps over OCing as this rig will only be doing encoding of video for me.
