Which CPUs does this board support?

It uses AMD's sTR5 socket and the WRX90 chipset, so it takes Threadripper PRO 7000-series processors. Standard Ryzen and Threadripper chips will not fit.

Does it need ECC memory?

It is built for registered ECC DDR5 RDIMMs across eight channels. Standard unbuffered desktop DDR5 is not the intended memory for this platform.

How many GPUs can it run?

There are six PCIe 5.0 x16 slots, so four large dual-slot GPUs fit with room to spare. Slot bandwidth splits depending on how many cards you install.

What case fits an SSI EEB board?

You need a full workstation or server case that lists SSI EEB support. Most consumer mid-towers will not fit it.

No. Networking is wired only, through the dual Intel 10Gb Ethernet ports.

How does it compare with the WRX80 version?

This is the newer WRX90 platform with PCIe 5.0 and USB4, while the WRX80 board is PCIe 4.0. Both target multi-GPU workstations, but this one is the more future-proof base.

What reviewers say

Owner feedback on this board is thin, but workstation builders praise its slot layout, power delivery and ECC memory support. Complaints center on its size, the cost of the platform and the need for registered DIMMs.

What people mention

ExpansionPraisedOwners value the six PCIe 5.0 x16 slots for running several GPUs at once.
MemoryMixedEight-channel ECC RDIMM support is welcome, but buyers note registered DDR5 is harder to source than desktop memory.
SizeCriticisedThe SSI EEB form factor needs a large case and is awkward to fit in standard towers.
NetworkingPraisedDual 10Gb Ethernet and USB4 are seen as useful for fast storage and network links.
StorageMixedFour PCIe 5.0 M.2 slots are fast, but some owners want more SATA ports for bulk drives.
