Our take on the MSI MEG X399 Creation sTR4 Extended

The MSI MEG X399 Creation is a flagship E-ATX motherboard for AMD's first- and second-generation Threadripper processors on the sTR4 socket. Its defining feature is a huge power delivery system and room for four graphics cards, plus three M.2 slots and eight DIMM slots for up to 128GB of DDR4. It suits workstation builders running heavy multi-core renders, simulations or multi-GPU compute. Against later TRX40 boards it lacks PCIe 4.0 and newer Threadripper support, so it only makes sense for someone already committed to the sTR4 platform.

Best forThreadripper 1000/2000 workstation buildsMulti-GPU rendering and compute rigsUsers needing many M.2 drives and lots of RAMOverclockers pushing high-core-count chips
Pros
  • Very strong VRM built for overclocked high-core Threadripper chips
  • Four PCIe x16 slots for multi-GPU work
  • Three M.2 slots plus eight SATA ports for storage-heavy builds
  • Eight DIMM slots support large DDR4 capacities
  • Extensive connectivity including dual LAN and USB
  • Solid metal-reinforced slots and heatsinks
Cons
  • sTR4 socket only fits first- and second-gen Threadripper
  • No PCIe 4.0 support
  • Large E-ATX size needs a roomy case
  • Chipset fan can be audible under load
  • BIOS and memory tuning can be fiddly with eight DIMMs

What reviewers say

Owners rate it as a serious workstation board with strong power delivery and plenty of expansion. Common complaints center on the chipset fan noise, memory stability with all eight slots filled, and the platform being a dead end.

What people mention
  • Power deliveryPraisedOwners say the VRM stays cool and stable with overclocked high-core Threadripper CPUs.
  • ExpansionPraisedReviewers like the three M.2 slots and four PCIe x16 slots for storage and GPU-heavy builds.
  • Chipset fanCriticisedSome owners find the small chipset fan audible and annoying under load.
  • Memory stabilityMixedFilling all eight DIMM slots can require manual tuning to reach rated speeds.
  • Platform lifeCriticisedBuyers note the sTR4 socket is a dead end with no path to newer Threadripper chips.

Questions and answers

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.
