The Gigabyte MC62-G40 is a cross between a server and workstation motherboard. The motherboard itself is designed to take AMD Ryzen Threadripper Pro CPUs and provide a capable computing platform in any role. In our review, we’re going to take a look at one of the many Threadripper Pro systems we’ve been reviewing, but this one is unique in its approach of being fairly server-centric as well.

The Gigabyte MC62-G40 is a 305mm x 267mm CEB motherboard. For this generation of boards, this platform is relatively compact. One of the great features of this platform is that it is a form factor that can accommodate many form factors, be it servers or workstations.

The sWRX8 SP3 socket is designed for AMD Ryzen Threadripper Pro 3000 and 5000 series processors.

We show this in our Threadripper Pro 5995WX Review. That means one can get up to 64 cores of “Milan” generation Zen 3 cores on this platform.

You can see our video including this motherboard here:

In addition to the higher core count CPUs, up to eight DDR4-3200 ECC LRDIMM/RDIMMs can be used for up to 2TB of memory capacity.

These DIMM slots extend to the top of the motherboard, so the power and component inputs are on the right side of the motherboard. Gigabyte keeps them out of the CPU airflow and aligns the power intakes so they face DIMM slots that require lower airflow.

Perhaps where this motherboard shines is in its expandability. There are seven physical PCIe x16 slots. Six of these are PCIe Gen4 x16 electrical, one is an electrical x8 slot.

Another feature you may have seen is that there is not only the CPU fan header near the power inputs, but there are eight 4-pin PWM system fan headers. These are all on the bottom of the motherboard and that may mean one needs longer fan cables to get to them.

At the bottom, there is also an M.2 2280 (80mm) slot for internal storage.

There is a second M.2 slot next to the WRX80 chipset.

Most of the drive and front panel connectivity is via parallel connectors to the motherboard. There are four 7-pin SATA connectors and three SlimSAS connectors. Each of these SlimSAS connectors can provide a PCIe Gen4 x 4 link, often for an NVMe SSD, or 4 SATA III ports for additional SATA storage.

On the back of the motherboard, we have the rear I/O which looks like a cross between the server and workstation I/O. There is a VGA port as well as a chassis identification button. Additionally, there are four USB 3.2 Gen2 ports. However, there is another block with USB 3.2 Gen2 Type-A and Type-C ports. We also have three audio jacks.

As for networking, we have an Intel i210 LAN, a management LAN, and two 10Gbase-T ports. These 10Gbase-T ports work with an Intel X550-t2 which sits on the motherboard under a small heat sink.

The out-of-band management port connects to the ASPEED AST2600 BMC.

Another small thing is that between the CPU and the subsequent I/O blocks there are two functions. One is a TPM header. The other is a WiFi M.2 2230 slot. This board does not come with WiFi, but there is a designated slot if you want to add it.

That’s a lot, so let’s move on to the topology to see how everything is connected.
