Server motherboard with 16-core Threadripper PRO

The GIGABYTE MC62-G40 bundles a Threadripper PRO 5955WX processor with 16 cores and 32 threads into a single sWRX8 workstation board. It targets professionals running heavily threaded workloads such as rendering, simulation or virtualisation who need a validated CPU-and-board combination. Buyers who want more storage lanes than the board provides or who require dual-socket scaling should look elsewhere.

Sustained load behaviour with 280W TDP ceiling

The integrated 5955WX operates at a 4.0 GHz base clock and can boost to 4.5 GHz within a 280W thermal envelope. Eight-channel DDR4-3200 feeds all cores simultaneously, while the WRX80 chipset distributes PCIe 4.0 bandwidth across seven full-length slots for multi-GPU or accelerator arrays. Builders who need higher core counts than 16 or who rely on liquid-cooling blocks not cleared for this socket will hit limits.

Installation notes for sWRX8 workstation builds

The board uses standard 288-pin DDR4 slots supporting UDIMM, RDIMM, 3DS RDIMM and LRDIMM up to 2 TB total with ECC and registered operation. Two M-key M.2 slots accept 2242 or 2280 drives, and three SlimSAS connectors provide additional PCIe Gen4 or SATA pathways. Installers must verify case clearance for the seven PCIe slots and ensure the power delivery matches the 280W processor rating.

Questions about this item

How much power does the included Threadripper PRO 5955WX draw under sustained load?

The processor has a 280W TDP, so plan cooling and a power supply that can deliver that continuously.

What memory must I supply to use the eight DDR4 slots?

You need DDR4 3200 registered ECC modules — UDIMM, RDIMM, 3DS RDIMM or LRDIMM — up to 2TB total across all eight channels.

Can I keep my PCIe 3.0 add-in cards in the seven PCIe 4.0 x16 slots?

Yes, the slots are backward compatible; PCIe 3.0 cards will run at Gen3 speeds in any of the seven slots.
