Gigabyte MC62-G40

I’ve just ordered a couple of these Gigabyte MC62-G40 boards, one has arrived and it’s creeping together as bits and pieces get delivered.

I was wondering if anyone else is running one (hopefully) and maybe you might like to poke your head in this thread and say hi and share some thoughts from your time with one.

I got mine from newegg.com, they are running a bundle at the moment; GIGABYTE Bundle Deal MC62-G40 Motherboard with AMD Threadropper Pro 3955WX $1198usd.
GIGABYTE Bundle Deal MC62-G40 Motherboard with AMD Threadripper Pro 3955WX CPU 16-Core/32-Thread Processor - Integrated by GIGABYTE - Newegg.com

There is a fair bit of control inside the board and even though there are 6 x16 pcie slots (plus 1 @ x8) I’m running out of them fairly quickly.

The motherboard that is being sent out is still on a very early revision of bios and the current bios R06 adds a lot of functions and fixes, so do that update asap. Make sure you take note of the IPMI password which is printed on a sticker below the serial number on the motherboard before you install it.
You can update the bios either through the IPMI or from a usb thumb drive directly from the bios.

Wendell did a video on the board but it has been a bit quiet on the Internet regarding this board as it is a all for functionality which perhaps makes it a less popular choice for a lot of folks. Wendell described it as a “get stuff done board” - check out his video here;

Here is an easy link to the motherboard’s user manual if you would like to have a bit of a flip through it;

The motherboard’s fit inside a Fractal Define 7XL in storage layout is good with enough room for cable routing and the like.

However, if you are going to run long cards like this quad U.2 card pictured below, be warned that the clearance is very tight over the m.2 NVMEs and a large heat sink like this full-copper one does foul on it. I have had to replace the copper one and go to a slim heat-spreader style.

Well as the bits & pieces start coming together on the MC62-G40 build, I have actually run out of slots and space in the Fractal 7XL.
Anyway, the journey continues …

I still see space :slight_smile:

How is the cooling situation with the all the HDD drives and PCIe NVMe drives?

I’ve placed some additional fans between the HDD disks and the motherboard on my system, because it ran hot during summer with room temperatures around 35° C

Teehee, yes that’s the X16 slot that runs at X8 on the board, it’s the only slot that does that because some of the lanes have been given to the slim SAS ports (I think it was them). I’ll try and find the info on it.

The spinning rusts have 4x 120mm fans in front of them and I’m getting a 3d printed spacer made up to bring them closer to the drive trays. The U.2 carrier cards do pose an issue with heat and I am about to change the layout of it all again to work more efficiently.

I’m going to remove the 3x Optane 905P out of the carrier cards and rehome them on to the side of the case frame and redo the layout of all the cards to allow for more airflow. I had the Dremel out today and opened up the carrier cards a bit to expose more of the back of the Intel P4510(s) to the airflow.

I made an account just to ask you this!

How do the iommu groups look for this board? Virtualizing GPUs for vms is my hope.

The price point is the best I’ve seen so far, and the support for the 5000 series pro threadripper is a nice upgrade option for later.

If you’re able to let me know, I’d really appreciate it. Thank you!

Hi rowr, can you be more specific with what you’re after and the best format to answer with? I can tree out a listing for you easily enough if that’s what you want.

While you get back to me I’ll give you a “bulk answer” reply :wink: HTH.

Thanks so much!

This, combined with the price point of the combo, is good enough for me to give it a go! It’s nearly a free motherboard so… I’m into it.

Cool! Make sure to come back and post here on level1techs with your setup. :smiley:

Oh by the way, it’s worth paying for the express shipping if buying from newegg as I had problems with my first one where I waited 13 days and they still hadn’t sent it despite me chasing them.
In the end they said they lost it in between the warehouse picking it and posting it. They gave me a refund after another 10 days of waiting. Since then I paid for express shipping and both orders went through perfectly.

Cut it out, it’s just hard to move with 16 spinning rust in there!

Now that you’ve said that, looking at it again, they do look a bit like they should don’t they. LoL

Does the system feel tippy/top heavy with all the drives?

No not at all. In that mode that Fractal call “storage layout” for obvious reasons, there are 12 drives down the front and another 4 in the bottom, so I guess you could say there is more weight below the midline than above the midline.

Those funny looking castors are a solid silicone dual wheel castors that are designed to carry extra weight and the dual wheel nature adds to stability. They slot in to the base of the adjustable Ikea computer case trolley replacing the cheap castors it comes with. The adjustable base frame of the trolley is opened a little wider than the case making it a slightly larger base footprint.

The other threadripper pro is in a 4U located elsewhere, but I needed something tall and thin for this location.

Very nice! That’s exactly what I’ve been looking for my future Fractal Define 7 XL build.

Where did you get those castors and what are the measurements of the castor plates?
As far as I could gather from the IKEA assembly manual (and a video), the plates are not screwed in, but held in place by a bent metal piece. That sounds a bit fragile. How sturdy does the whole thing feel? Do you think it’ll break if you ever need to replace the castors?

This is the link to the case trolley (don’t know what it really is).

The width is adjustable and you tighten it up from underneath, it does not move.

This is the style of castor and you just buy the variant for the weight you have.

The mounting plate is a direct swap for what the Ikea ones come with mounting plate wise, both are 42mm just swap out the whole castor, easy peasy.

So long as the mounting plate is the same size, you could go with something more industrial if you’re on concrete. I had to think of my hard floors.

Maybe buy the Ikea thingy first and have a look and go from there.

HTH. :slight_smile:
