ASUS WS C621E Sage Extreme Power Intel® Xeon® Processor Workstation Motherboard for Two-way XEON CPU performance, with U.2, M.2 connectors, dual Gb LAN, USB 3.1 Type-C & Type-A, 10 x SATA 6Gb/s ports

If you absolutely, positively must have the most ridiculously overkill desktop PC in the neighborhood, look no further! After Intel all but abandoned their HEDT offerings, the geniuses at ASUS took a high end server platform (LGA 3647) and shoehorned it into a desktop motherboard loaded with desktop-friendly features like USB type C port, multichannel audio, onboard troubleshooting buttons, and a rather fast POST considering what it's capable of.This platform is not new (came out in late 2017 which makes it around 5 years old at the time of writing) but that just means you can find compatible CPUs and RAM second-hand for pennies on the dollar. I have two Xeon Gold 6142 CPUs and 256GB of DDR4 (registered ECC) RAM. This makes running multiple development VMs effortless and would probably do very well for rendering videos. It's new enough to be officially supported by Microsoft for Windows 11 though you will need to purchase a compatible hardware TPM since a firmware update removed the ability to use fTPM for whatever reason.You get 7 full-length PCIe slots (4 of which are x16, 3 are x8), only one M.2 slot, and 4 U.2 connectors (which can be adapted to fit M.2 drives) which lets you pack the board full of accessories like GPUs. Forget about the limited PCIe slots and lanes on the consumer boards, you won't run out. There are 12 RAM slots and you get 1 DIMM per channel on the 6-channel memory controller for each CPU. (The CPUs actually have two 3-channel memory controllers and sub-NUMA clustering is available to expose them more accurately to the OS as two NUMA nodes per socket.)You also get some features reserved for servers such as the BMC that lets you remotely manage the system over the network including getting into the EFI firmware. Pro tip, use the included VGA header to view what's going on if you're getting a black screen with an external GPU since this port is attached to the BMC and gives you more information on-screen even if the main system isn't POSTing for some reason.This board is large and will not fit in many desktop cases due to the drive bays getting in the way. I use a Corsair 750D which is large enough but requires a few holes to be drilled and covers up some of the cable management grommets. The sockets are of the "Square ILM" design which is hard to find coolers for but the Noctua NH-D9 DX-3647 is the one to get; as you can see in my picture, the fans can be attached in such a way that none of the PCIe slots get covered, and this works as long as you have ventilation at the top of your case.If you just want something to play games on, you'd be better off spending the money on a top-of-the-line GPU and a midrange Z790 board. But if you want to build the desktop to end all desktops, know that you're building something truly unique (and probably the last of its kind as single CPUs continue to get more and more cores, making dual-socket unnecessary for most).

Me gusta la tarjeta, pero la verdad tiene detalles no tan padres por ejemplo la distribución de PCIE, por alguna razón si solo tienes un CPU solo tienes PCIE 3,4 y 5, tres se comporta como de 8, no hay forma que funcione de 16 (aunque dice el manual que es mixto 8 por cpu y 8 por chitset), con lo cual si metes la tarjeta de video y quieres meter por ejemplo Asus Hyper M.2 X16 PCIe 4.0 X4 (que para rematar tiene solo 1 M2), pues se vuelve un problema. si o si necesitas el otro cpuLo siguiente es la gestión de ventiladores y curvas, no tiene nada de, si tienes ventiladores DC, olvídalo no hay forma de controlar sus velocidades)El soporte para hot swap para PCIE es un doloroso, ni te frustresLa documentación es totalmente nula, muchos de las configuraciones las encuentras en reddit o foro de discusiones, asus ni las graciasupdate después de 1 año y 8 meses ha dejado de funcionar, la tarjeta pese a tener garantía hasta 2025 asus mexico no se hace responsable, rifate con US, amazon se deslinda también

First issue is that Amazon mailed this out without a box or packing, just slapped a shipping label on the Asus retail package. So, the box and motherboard got beat up (cpu covers got knocked off even)Crossed my fingers and tested the board out, it POSTed! However, sadly, it took further testing, for me to realize the U.2 ports weren't working, no matter what cable, or device, I hooked up to the u.2 ports, there would be no detection.Also, the fan headers weren't working properly, not all fans would turn on, and each reboot had a different outcome, in terms of which fan would actually run, if any. This was a motherboard issue, the fans are working on other systems, and the bios simply showed different fan detection with each reboot (adjusting settings did nothing)Based on the poor reviews, I cannot say whether my issues stemmed from amazon's poor shipping (for such an expensive, and sensitive piece of equipment) or if these issues are due to Asus's poor QC with this board, maybe a mixture of both.However the board comes well equipped with features, and accessories, and was manufacturered with good quality components, you can really feel and see it... If only the board was 100% functional

The motherboard looks used, it has dust all over it. Both CPU sockets covers were not secured at all. One of the CPU sockets has bent pins.

First review ever written. The board came a year ago, and I built up a server that appeared to run decently for a while, though it would have glitches here and there where I had to do a few OS/software reinstalls.It finally died and I had the board sent to ASUS customer service, which by the way, I was never able to get an RMA made through their online RMA process, it's laden with errors. I had to email them directly and talk with 4 or 5 different "techs" before they made an RMA on their end. Shipping the board to them cost a decent amount out of pocket, only to get an email from them saying some of the CPU pins were bent and not covered under warranty. I set two Xeons into the sockets, installed once, and removed once, properly and expertly, and even returned the MB in it's original package. The board costs near $600 at the time of this review, and they want to charge me $1000 to fix the bent pins.ASUS is a joke. I'm having them return the MB that I suspect they jacked up on purpose, and will fix it myself or use it as an expensive reminder of why you should never buy into ASUS workstations.
