Gigabyte's AMD Epyc server motherboard

NumLock21

Motherboard maker Gigabyte had just announced their server motherboard for AMD Epyc processor. Called Gigabyte MZ31-AR0, the board uses a single socket configuration with 16 DDR4 ram slots. It has 5 physical x16 and dual physical x8, with all of them running at their full speed, except for one of the x16 operating at x8 mode only and 24pin with dual 8pin for power. Bottom right, there is a M.2 and 4x slimSAS for 16 SATA ports, where a single slimSAS can running up to 4 SATA drives. On the I/O, it has dual USB 3.0 and 2.0, RJ-45 gigabit management lan, serial, VGA, ID button, and dual SFP+ 10Gb/s ports using Broadcom® BCM 57810S controller. No price or release date info yet.

It definitely looks like a step up from what I'm used to seeing. Let's see who actually gets a hold of them when they come out.

Can't help but think how there was this massive drive to miniaturize, and now there's CPUs the size of floppy disks. Giggidy.

With smaller CPU VRM and more space efficiency, it's possible. Hell, it's possible to make an ITX board using that socket, but everything's a squeeze on there.

Shame that it doesn't have a couple more usb 3.0 ports on the back plate , and shame it doesn't have some basic sound card.

 

A bit overkill on the memory VRMs , 4 phase vrm per set of 8 memory sticks ... guess they went for spreading heat across multiple mosfets and reusing cheaper mosfets everywhere on the board instead of buying multiple different mosfets each best fit for some job.

 

Still, it's beautiful board.

Why does a server board need sound and more then 4 usb?

It doesn't. But, they could have reused the same design for a workstation board .. for example save some money by taking out the second slot of each memory channel (get the board with only 8 memory slots) along with maybe one or two phases of the vrm for each memory side.

 

Could also just drop the 2 x 10gbps optical network card (which is probably around 150$ worth of the board price) and bundle a 100$ aquantia based 10gbps copper network card.

 

You'd have a nice board for something like real time 4K 60fps h264/hevc encoding, for live streaming something.

 

You have pci-e slots for one or two 4K capture cards with connection directly to cpu and you can have a 16-24 cores/ 32-48 thread cpu to do real time CPU encoding (better quality than gpu encoding).

 

The basic sound card would be good for the line input from some microphone mixer / pre-amp or whatever, no need to buy a 30-50$ sound card just for a microphone input

 

yeah, you can probably do this with cheaper threadripper as well, but since this board is so "spartan", there's no reason why this design couldn't be repurposed to a workstation design.

ps. oh yeah, and for a server motherboard this one lacks the 100mbps/1gbps separate ethernet for management purposes, something fairly cheap and easy to implement... maybe 2-3$ in parts.

But there is 100% no use for sound on a server and if you want to use it as a workstation, and not use TR for some reason, use an external USB sound card.

 

It's a server board where 10Gbps connectivity now days is almost a requirement and it's better to have that onbaord than taking up a PCIe slot.. SFP+ also works with copper be it DAC or 10GbE.

 

The board isn't spartan, go have a look at the back of every Dell/HPE/Supermicro server.

 

Also give up ram slots on a server motherboard, HELL NO! :P

 

P.S. it has a 1Gpbs management port look above the USB3.

Uhh this is for servers not workstations, so again why would they do any of this. Ya they could make a workstations board for epyc, I would like that. But even on that board I would want 10 Gbps networking

because you can substitute 2 cpu sockets with one of these, its actually smaller :p

How can video cards fit there? Aren't they going to hit the RAM sticks?
