Asus B250 Mining Expert Motherboard with 19 PCI-E Slots

20 Aug

It seems that the race for a mining motherboard with the most PCI Express slots is far from over with the AsRock H110 Pro BTC+ and Biostar TB250-BTC PRO probably being only the start. Asus is planning on joining the party with not just 12 or 13 PCI-E slots, but with 19, though you might be limited to actually using only 16 of them. We already know that you are limited up to 8 GPUs from a kind (AMD or Nvidia) under Windows, so 16 max if you mix them. With Linux though more GPUs from a kind that what Windows allows are usable, but then again more than 16 at this point might not be possible. This is probably why Asus are talking about this product as supporting 16 GPUs even though it does come with 19 slots…

For now Asus is just teasing us with this motherboard and there are no full details about it, including info on pricing and availability. Still it shows that the company has interest in the mining market, especially after also releasing mining oriented GPUs. Unlike some other manufacturers however Asus is showing that they are designing their mining products with miners in mind and not just pushing something that is not worth buying like some others. Their Asus B250 Mining Expert mining motherboard comes with three 24-pin ATX power connectors for directly connecting up to three power supplies without the need to use external means to synchronize the PSUs. There are also three 4-pin Molex power connectors on board for powering GPUs, though you probably will use powered risers and won’t be needing these.

We are yet to see more information emerging, but things are definitely looking interesting already. What you need to be prepared with motherboards for mining supporting so many GPUs is that there will be some unexpected challenges when building the mining rig. Cable lengths, connector spacing, enough space for proper cooling and so on. Design challenges emerge and the more video cards you use, the harder it gets to make things work as expected. Though once you clear the design for let us say 16 GPUs, then the next mining rig should be much easier and problem free to assemble… hopefully.

Probably just me, but I couldn’t understand the first sentence in this article. Any chance someone can clear this part up?

@Kol Tregaskes, teaser means it’s not a product available yet just a prototype or proof of concept or whatever you won’t find it on market.

It would be really nice is this product came with 19 risers that were NOT powered risers but would get their power from the motherboard. Not THAT would be a huge improvement to cabling.

This Asus teaser looks amazing.
Being a miner for over four years, using your mining rig for STORJ or any other similar platform is great to stake up on more cryptos. This teaser should have at least four ram slots, and if possible one more cpu so user could mine with the second cpu, that would be the ultimate board.

This motherboard should have 4 RAM slots.

16 GPU limit is not true! Most old soho mainboards were not able to handle more lanes.
New PLX chipsets can handle up to 104 lanes.
You will be able to riser 18x pcie to another 4x plx switch. That makes 18×4=72 cards

The BIOS is already setup to spin it, like with Biostar or AsRock Mining Boards.

Well – you need to find out a bit more on your own and the driver will make you insane – it is possible.
Dont lose your head in a “headless mode” could destroy your OpenCL ;) — have fun.

Anyways this blog is amazing and nobody is able to know all the news or technical specs.
But I get 10% of my needed informations and sources from here.

Thank you! And keep it rollin´

I have Asus B250 Mining Expert
i’m run with 13x1080ti
I’m put another 1080 ti on the board it was not boot.

We have this board and got as far as 3 VEGA before problems. Windows 10 device manager would show 4 VEGA but one with an error. It would be random which one had the error. Error 46 means not enough PCIe lanes. Using an i3 7100 CPU.

Putting a 4 way riser in one PCIe and running 4 GPU off that solved the problem. This begs the question why buy a board with so many PCIe if a normal board using 4 way risers will get you what you want?

Have two of this boards on two rigs – running 19 GPU’s on each. 11x MSI RX 580 8GB + 8 P106-100 (6GB). The secret is you need at least 8x NVIDIA P106-90 (3GB) or 8x P106-100 MINING CARDS in your rig setup. Without them you can run MAX 13x GPU’s on this board.

Hi I am having a problem getting my screen to work. It keeps going from analogue, to HDMI, but I plugged in a HDMI screen with HDMI cable. Can you tell me why it wont show the screen.

I have a ASUS B250 Mining Expert Motherboard, on my rig. With 6x RX570 cards on the rig, and 3 1070’s. Screen is messing me around everything is coming on except for the screen. Please help…….
