Board Features
The GIGABYTE MZ72-HB0 is an E-ATX motherboard and it is versatile in functionality due to its dual SP3 sockets designed for AMD EPYC 7003 and 7002 processors. It can be installed into a regular chassis with E-ATX support, but most system setups using this model will likely be in 1U chassis, which is designed for server and rack deployment. It has plenty of PCIe support, with five full-length PCIe 4.0 slots in total, which can operate at x16/x16/x16/x8/x8. For storage, there are four 7-pin SATA connectors, one PCIe 4.0 x4 M.2 slot, two SlimSAS PCIe 4.0 x4 NVMe slots, and three SlimSAS ports which can accommodate either twelve SATA ports or three additional PCIe 4.0 NVMe devices. Memory support includes sixteen memory slots (eight per socket), with support for DDR4-3200 or DDR4-2933 memory, and can accommodate up to a maximum of 4 TB of RDIMM, LRDIMM, and 3DS varieties.
For cooling, there's a total of six 4-pin headers available, including two for CPU coolers, and four for chassis fans. It does include a TPM 2.0 header for users wishing to run the Windows 11 operating system, but users will need to purchase an additional module to use this function as it doesn't come included in the packaging.

The MZ72-HB0 does include BMC functionality, which is delivered by an ASPEED BMC controller and includes a Realtek RTLS5411E Management LAN port and a D-sub video output. For server and rack deployment, there's a UID button that includes a functional LED.
Test Bed
With some of the nuances with Intel's Rocket Lake processors, our policy is to see if the system gives an automatic option to increase the power limits of the processor. If it does, we select the liquid cooling option. If it does not, we do not change the defaults. Adaptive Boost Technology is disabled by default.

Awesome, I always learn something here!The 20A receptacles aren't all that unusual, a good commercial-grade 20A is in regular stock at my local hardware store... and I live in a remote small town.
Mikewind Dale's suggestion is sound: run a 20A if you're putting anything new in. Just be certain you don't string that behind an older 15A breaker! Should be a home run from your receptacle direct to the panel. Don't know if isolated ground specifically makes a difference, but it would likewise be a trivial cost.
Does anyone make a 20A ATX power supply? They are more common in the data center, and one of my home rack PDUs showed up in the 20A version. (Then I got a Raspberry Pi, and replaced two servers with my MacBook Pro M1, and the power delivery system looked a bit embarrassed. So of course it's time to buy more silly gear...)

I never understood why the US never changed the voltage system. The reason the US still uses 110V dual phase, is because after supporting World wide triple phase 220V the government found out it saved loads of copper. And the copper industry was depending on using that much copper.But nowadays the Chinese make the copper anyways.
3600W from a normal fuse. 11kW from a normal triplephase 3 fuse outlet is your house has triple phase.
Being wary about fuses just is not a European/Asian thing. Nor should it be American

Server board? Please tell me it supports ECC memory.Mikewind Dale - Wednesday, August 4, 2021 - link
It supports RDIMM and LRDIMM. Although that's not the same as ECC, it's pretty much 100% correlated with ECC. I've never heard of a server board that supports RDIMM and LRDIMM but not ECC.Heck, most ThreadRipper non-Pro boards support ECC, and many Ryzen boards do. It would be unthinkable for this board not to support ECC.

And just for comparison, Gigabyte's ThreadRipper Pro WRX80-SU8-IPMI board says "Support for UDIMM (ECC), RDIMM, 3DS RDIMM and LRDIMM memory modules". Notice that "ECC" is a qualifier for "UDIMM". It appears that for Gigabyte, ECC is only a question for UDIMM; for RDIMM and LRDIMM, ECC goes without saying.bananaforscale - Friday, August 6, 2021 - link
"Size E-ATX"There's "larger than ATX" but there's no E-ATX standard.

When will this motherboard be available at online retailers? By googling I find that it is widely available only in Russia. When will it be available in the US and other countries?MirrorMax - Saturday, August 28, 2021 - link
Few errors in the article. Epyc rome already had 280w cpus with the 7H12, which was supported on the rev1 board. and there's nothing new on the rev3 board except a rome/milan bios instead of the naples/rome bios from what I can see. I assume they couldn't fit all 3 gens into one bios. Rev1 boards are also flashable to milan/rome bios according to gigabyte support. they are not too happy about customers bios flashing unless they have issues so i assume thats why they released this a seperate Rev not just a bios update.
