Gigabyte GA-H110-D3A 6x PCI-E GPU Mining Motherboard

8 Sep

The chances are not many of you have heard about the Gigabyte GA-H110-D3A motherboard that is intended for 6x GPU mining rigs and the reason for that is probably the fact that Gigabyte hasn’t been promoting this product much as a mining motherboard. Gigabyte is a bit late on the GPU mining front with a motherboard designed for mining rigs with the GA-H110-D3A, even though the motherboard comes with up to date specs. That however does not mean that the company hasn’t been offering other higher-end products that are good to go for use for crypto mining, there are quite a few of these already and we have been using some of the models ourselves. The GA-H110-D3A however is still new for us and we are going to be giving it a try and sharing our experience with the motherboard pretty soon anyway.

The key thing about the Gigabyte GA-H110-D3A is that it comes at an attractive price and has all the features you need in order to build a regular GPU mining rig with 6x video cards. It is a basic motherboard with 6x PCI-E slots (single x16 and five x1 slots) that needs to be durable and reliable and be cost effective, so no shiny extras that you won’t be needing anyway for mining. The motherboard comes with a M.2 slot allowing you to use SSD in that format and save some extra space and cabling, especially power cables as they may be a problem in some situations. There are also a couple of things to make the product more attractive marketing wise, though you probably won’t benefit much from them such as USB 3.1 Gen1 support, high quality onboard audio design or a Realtek Gigabit LAN with cFosSpeed internet accelerator software. Some of the extra features might be actually helpful however such as Humidity Protection Glass Fabric PCB, High ESD Ethernet & USB Port Protection or High Temperature Protection Lower RDS(on) MOSFETs Design as often mining rigs are not working in the best possible conditions.

Gigabyte has an interesting microsite for mining that is centered on the H110-D3A motherboard, but also has some more useful information for other of the company’s products that can be used for mining. The most interesting part is probably the table listing 12 different Gigabyte motherboards with information on what BIOS version to use for mining and how many GPUs can be used on the specific model. Do note that there are some motherboards that do require the use of additional M.2 to PCI-E adapter in order to reach the listed number of GPUs. For example the Z170-Gaming K3 is one of the board that we have used a lot for 6x GPU mining that did not have support for more than six video cards up until BIOS F22, but now Gigabyte seems to be saying that it will work with F23a using an additional M.2 to PCI-E adapter (something we need to test). There are even some motherboards for up to 9x GPUs with dual M.2 adapters like the Z170X-Gaming 5 and Z170X-Gaming 6, though you might actually have a problem using all 9 under Windows for example.

Here is the Gigabyte microsite with some information and tips regarding mining motherboards…

This looks like one powerful MF. Nice, I like that it has 6xpci, I have too many things to plug into my current board.

Looks like a great board.

Im really excited to hear what the feedback will be.
I am looking at purchasing one of these boards to build up a 1070 mining system.

All the help and guidance i can find is appreciated

We like the board but we have issues getting the 6th GPU to work in windows.

We have quite a few but none are running 6 GPU.
The one i’m working on right now is 6x MSI GTX1070
I can get 5 to work with the new mining bios.

If i turn on mining mode I get a bios loop.
If i turn off mining mode and turn on 4G Decoding i get a black screen.
If i turn both off I get 5 GPUs in windows but the 6th is short on resources.

I’ve tried turning off just about all the other peripherals in the bios hoping to free them up, but no dice.

What is the BIOS version of the motherboard, what Windows are you using? Is the OS installed in UEFI mode or in Legacy, make sure you use Windows 10 in UEFI mode.

DEEGAN POPE i had the same issue. enable IGFX and use as default, after enabled 4G and using pcie in gen2 mode it should work fine! :)

Can anybody confirm a working 6GPU rig with this MB?


October 19th, 2017 at 14:54

Yes, we have built a couple of mining rigs without problems with this boards. The key is to update the BIOS and use a UEFI installation for the Windows 10.

Thank god for this thread. I also had a lot of difficulties making the 6th card working (Zotac GTX1070) while the first 5 worked easily. The key for me was to enabling IGFX in the bios from the advanced startup menu.

I have the right configuration for the gigabyte H110 -D3h motherboard to identify 6 gpus but you have to follow my steps
assuming you have windows 10 and 8 gigs of ram

1-Upgrade to bios f 22 ( upload it onto a USB stick and flash the new bios… it will re flash the bios within 3 to 4 minutes max )
BIOS Download Link:

2-After successful new bios installation please enter bios & enable the Mining mode …

3- Enable the internal graphic cards on the board…. and disable the sound card …make sure that you enable the max link speed to gen 2 under M.I.T / Miscellaneous Settings / Max Link Speed

and you are good to go

4- your board should be ready for a 6 vga card verification now… if id didn’t boot for any reason… restart the computer… enter bios and enable the csm option ( it worked for me but didn’t figure out why till now )

happy mining every 1

bought one of these a month ago. works great! 6th card does require gen2 settings, but also works great. Too bad about the m.2 slot not supporting an additional pcie. pcie splitter cards do work on this board so you can go above 6 cards no problem. Currently running 8 amd cards. hope this helps someone.

Bought m.2 pcie riser’s, tried two and it does not see the card, so this mobo can not be a 7 rig?


March 5th, 2018 at 10:19

Yes, this motherboard works only with 6 GPUs, you cannot use the M.2 slot for an extra one.
