ASUS Pro WS WRX90E-SAGE SE EEB Workstation Motherboard, ATX AMD Ryzen Threadripper PRO 7000 WX-Series, ECC R-DIMM DDR5, 32 Power-Stage,7xPCIe 5.0x16, PCIe 5.0 M.2, 10Gb & 2.5Gb LAN, Multi-GPU Support

I am using this motherboard with the AMD Threadripper PRO 7975WX. Right now it works nice and solid, very stable. I love this board. But when I first installed the motherboard, I was very frustrated pulling my hairs out because Windows 11 Pro for Workstations kept getting corrupted during installation and every time I installed the NVIDIA graphics card driver it would get stuck in an endless boot loop. After days of troubleshooting and fear of having to find the needle in the haystack bad component and dealing with return delays, I found the culprit! It turns out all these problems were caused by the onboard VGA controller, and when I turned off the little VGA-enable switch on the motherboard, everything went from unstable to rock solid! The Windows 11 install and NVIDIA drivers went real smooth after turning off the VGA switch. This VGA feature is intended for server rooms and I think ASUS should make people more aware of the pitfalls of leaving this switch enabled. There are some reviews here reporting defective operation of some boards, and I bet there's a 99% chance it's caused by this stupid little switch being on. There is one other tip to point out, the installation manual description of the CPU power connectors is incorrect. I spoke with ASUS tech support on the phone and they acknowledged they are going to escalate this mistake and fix the manual. The CPU has four power headers: CPU1, CPU2, PCI_CPU1, and PCI_CPU2. The manual illustration indicates to plug in just one of the CPU power headers if you have a single power supply. However, I found that the motherboard won't even power on unless I plug in the two main CPU power headers. I also plugged in the two PCI_CPU headers to be on the safe side. Additionally, there are two supplemental PCI power headers for the PCI slots next to the main ATX power plug. While the manual says this is only needed if you have two or more graphics cards, I found that the BIOS startup screen complained when I didn't have at least one of them supplied with power because I have two PCIe cards (a GPU plus an M.2 SSD card). These are not two GPUs, but just two different cards. At some point ASUS will fix the install manual based on my phone call. Simply get a good high capacity PSU and plug in ALL the power headers instead of picking and choosing which one, and you're good. Note that this is an EEB form factor, which is quite large. You don't necessarily "need" an EEB specific case however. I was able to get it to fit great in an ASUS ProArt PA602 Wood Edition case (ATX/EATX size case). I simply had to re-arrange the standoffs in different spots and skip 3 of the standoffs on the right edge of the board (not really needed, the motherboard is plenty secure with the rest of them). I have a total of 8 M.2 PCIe 5th gen SSDs (Crucial T705). The motherboard has slots for 4 of them and I am also using the ASUS Hyper M.2 PCI card for another 4 (plugged into the first PCI slot since the first two slots support gen 5 speed in bifurcation mode). I have 32TB of BLAZING FAST storage, I love it! Adjusting the fan curves is split between the BIOS settings and IPMC web admin. The fan speed adjustments for the VRM, M.2, and USB4 heatsinks are in the BIOS. The CPU and chassis fan curves can be set in the BMC which allows firmware-level computer management over the network (first you'll have to set an IP address in the BMC section of the BIOS to access the IPMC web settings). I HIGHLY RECOMMEND this board for creative pros, AI, software development, engineering, etc. This is the best sTR5 socket board on the market right now for Threadripper PRO. I'm very happy with it.

I recently purchased this MB and it arrived with a CPU socket marked "SP6" installed instead of the sTR5 socket as specified in the written Amazon description. To add to the confusion, the photos with the Amazon listing show a socket marked SP6, as do the photos on the Asus website. These sockets are similar but different and support different processors. The AMD Threadripper Pro CPUs for which this MB is intended are not compatible with the SP6 socket. So far, not much help from Amazon and Asus in determining what's going on here. Is this socket mismarked, was there an error in the Asus manufacturing process, or some other explanation?

One beast of a motherboard! I will admit tho that it took some time, tinkering and patience to set up but, once I got it up and running, it has been a rock solid, and very stable board. I've paired this bad boy up with a Threadripper PRO 9965WX, 256GB of Kingston Fury Renegade Pro DDR5 RDIMMs and 4 Samsung 9100 Pro 4TB NVME SSDs and 2 Nvidia RTX 5090s. Plan ahead when it comes to a PC case to install this EEB form factor board in. The WRX90 is very big and very heavy. It weighs a staggering 12 pounds! Great motherboard, you just need to know what are doing. Definitely not a mobo for beginners and the owner's manual is not the greatest. I highly recommend if you're looking to build yourself a solid workstation.

I have had no major issues after 2-3 months, using Debian Linux NOTE: On first boot(s) RAM training may take from 5 minutes to an hour. If you have a blank screen, the board is probably not broken, nor is your GPU- the RAM is training, be patient. I wasted an entire day and $100 in cables, thinking there was some issue with my DP cables. Just be patient…. Seriously NOTE: Needs a Threadripper *Pro* 7000 series CPU. These are 7955WX, 7965WX, 7975WX, 7985WX and 7995WX. NOT 7950, 7960, etc. NOTE: There is no integrated graphics- you will need a GPU to drive a display. For a cheap, low profile option to use alongside large GPUs used for compute, I bought the Intel Arc A310 Eco by Sparkle ($99.99!) to drive an 8k display with max power usage of 50W NOTE: Make sure you use the QSL data from the Asus when picking your RAM. People who claim the board is not stable either had bad luck, got older/earlier builds of the board, or were using non-QSL RAM. I’ve had zero stability issues. I chose w V-Color kit from the QSL list NOTE: The CPU socket is sTR5, which is a larger, rectangular socket. This is important to know when buying a cooling solution. Coolers for AM5 will work, but there are now 2-3 coolers designed specifically for sTR5 NOTE: The board is larger than ATX and not the sane as eATX. It’s SSB. Make sure your case can mount an SSB board. I know Silverstone has some 3U and 4U SSB cases. Phanteks has a bunch of SSB tower-style cases Coolers: Off the top of my head, from months of investigation: - Eisbaier Aurora Pro 360 (AIO, ~$200) Alphacool Eisbaier Aurora Pro HPE 360 (AIO, ~$250) - Noctua NH-U14S (Fan/heatspreader, ~$125, I think) - SilverStone XE360-TR5 (AIO, ~$350)

IPMI, BMC are both atrocious - the only utility of this motherboard that isn't an impedance is the number of pcie slots. If you are ok with an IPMI system that functions ~40-60% of the time then this product is for you. Context: I've used this motherboard/system daily for more than 6 months, I'm never buying another motherboard in this line again.
