The board has 6 power phases for the CPU. But most importantly it has 18 PCI-E x1 slots and 1 PCI-E x16 slot. It also has 3 PSU slots. But can it support 19 GPUs?<\/p>\n<p>Let\u2019s read the user\u2019s manual first. The manufacturer recommends installing graphics cards as follows.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-415\" src=\"https:\/\/2miners.com\/blog\/wp-content\/uploads\/2018\/04\/image3.jpg\" alt=\"\" width=\"500\" height=\"451\" data-wp-pid=\"415\" srcset=\"https:\/\/2miners.com\/blog\/wp-content\/uploads\/2018\/04\/image3.jpg 500w, https:\/\/2miners.com\/blog\/wp-content\/uploads\/2018\/04\/image3-300x271.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/p>\n<p>As you see, 19 GPUs for mining can be installed only with the use of P106 cards \u2013 other options won\u2019t do.

The best result was by installing two Nvidia cards, but it was far from perfect \u2013 the RX570 hashrate dropped to 27 MH\/s, while on the other rig its hash rate was always 29. Our further experiments got us nowhere. Besides, the board doesn\u2019t like overclocking at all \u2013 when we modified frequency for one card, the hash rate of the others went down.

But we know for a fact that on its own Asus motherboard cannot support even 10 cards, let alone 19. I am sure that it\u2019s possible to install more cards on one rig with this motherboard, in fact, user reviews demonstrate that \u2013 some managed to install 13+ cards successfully, but still, it was just the result of their thorough and extra work.<\/p>\n<p>It is also possible that we were unlucky to buy a motherboard of poor quality. But for $300 we expected smooth operation and the payback of every PCI-E \u2013 instead, we just wasted our time searching for the functional combination. We don\u2019t think changing Linux to Windows would have changed anything, not with our poorly made board for sure.<\/p>\n<p>So isn\u2019t it better to have two rigs with 12-14 GPUs instead? This way you can easily install, update and overclock a good number of cards without any problem. Besides, the setup is so easy that it takes less time than assembling the rig case. Even financially 2 motherboards with CPUs kind of cover the cost of DDR4. It is more expensive than DDR3 nowadays, plus the CPU for the 1151 socket costs more.<\/p>\n<p>So if you like playing around with hardware and have lots of patience, you can buy Asus B250 Mining Expert. But if you want a smooth operation and easy setup, our advice is to look for less questionable boards.<\/p>\n<p>Which motherboards do you use for mining?
