i think this is not the question:
this board is not installed alone in a case. several GPU accel. have to fit in it.
The ASRock W790 WS has double the VRM phases of the other boards. All the boards have over-specified VRMs even for a 2000 W sustained load. You are unlikely to exceed 1000 W with liquid cooling. I would choose based on the PCIe slot layout and after-sales support. You will need BIOS fixes on these boards as they are all buggy especially when overclocking. See my post above.
good info thanks. Just based on Asrock’s support for you makes me want to buy theirs, and the fact its $400 less than Asus’s. I have a PSU, case, and so on. For cooler, cpu ram and mobo it would be about $3000. Yikes. Gotta find some used ram lol
After being disappointed with the complete lack of higher density XMP RDIMM kits available I broke down and bought some normal 4800MHz 64GB Hynix sticks; turns out the 4800MHz server stuff will overclock just fine as long as you can cool it, I'm running DDR5-5945MHz 34-38-38-96 timings @ 1.35v on the memory now and am getting some pretty good bandwidth numbers.

My friend ordered W790 for same, for work and gaming, ordered Asus W790 SAGE SE but it was hard choice because as second choice was ASRock W790 WS. ASRock have better VRM, Builtin WiFi, 2xThunderbolt, but have one big minus only 4-channel memory versus Asus with 8-channel. So he ordered Asus and additional bought PCIe WiFi with Intel AX210. What I read so for OC is actual best ASRock because have topper VRM from all W790 motherboards.

I already bought one 2 weeks ago on Amazon.de but it has not been shipped yet although 1 was in stock.
not clear. I guess the manualy entered BCLK is automaticaly adjusted to match valid DDR frequencies.
This may be off topic but I was not sure if it is worthwhile to create another thread. WS790 motherboards will not take Xeon CPUs something we discussed before on this thread, this stops the tradition of shared CPUs between server and workstation platforms.
Given that, let me recap my understanding:
- Broadwell is the last platform that allows shared CPUs between HEDT, Workstaion and Server platforms.
- Cascade Lake is the last platform that allows dual socket workstation motherboards, there is no more after it. ASUS WS621e SAGE is the last dual socket motherboard you can buy other than custom HP, Dell and Lenovo workstations.
- Ice Lake is the last platform that allows you to buy server CPUs to be used in workstation. Asrock C621A WS is the only motherboard that allow you to use an Ice Lake cpu in workstation. There are no Ice Lake based workstation from Dell, HP etc.
Given how expensive the new Sapphire Rapid platform is, I am curious what will happen to workstation market.

Why would anyone want to put a low-clock-speed server Xeon in these boards? The Xeon-W starts from sub-$400 IIRC. I don’t see any artificial segmentation here. The platform is not qualified for server CPUs. On this low-volume enthusiast workstation platform the board partners should focus on overclocking and extreme performance. On the AMD side there is further segmentation with Threadripper PRO.
