- Which CPUs fit this board?
- It uses the sTR4 socket, so it takes AMD Threadripper 1000 and 2000 series processors. Newer Threadripper generations will not fit.
- How many M.2 drives can I install?
- There are three M.2 slots, alongside eight SATA III ports for 2.5-inch and 3.5-inch drives.
- Does it support four graphics cards?
- Yes. It has four PCIe x16 slots and supports multi-GPU setups, including CrossFire.
- How much memory can it take?
- Eight DIMM slots accept DDR4, supporting large quad-channel configurations for workstation workloads.
- Is it worth it over a TRX40 board?
- Only if you already own an sTR4 Threadripper chip. A TRX40 board gives newer CPUs and PCIe 4.0.
- What case size does it need?
- It is E-ATX, so you need a full-tower or a case that explicitly lists E-ATX support.
- Where is the MSI MEG X399 Creation sTR4 Extended cheapest?
- At Newegg, for $1,043.11, as of our latest check.
