ASUS Prime Z390-P LGA1151 (Intel 8th and 9th Gen) ATX Motherboard for Cryptocurrency Mining(BTC) with Above 4G Decoding, 6xPCIe Slot and USB 3.1 Gen2

It does indeed utilize 6 GPUs as some others have stated. You do need to disable things like HD audio, and enable 4g encoding. (I did not need to update my bios to do this.) It also does appear to be that the GPUs DO need to be the exact same make/model/etc. In fact, yesterday I bios modded my cards, and now it only sees 4 and will not even post with more than 4 installed. Each card works great solo.I will be testing today once home from work if I flash them all with the exact same bios if the mobo will then boot with all 6. Up until this point though, the motherboard has worked great out of the box, looks good, and has been exceptionally adequate for my needs. Especially for the price at which I purchased it.UPDATE: I actually added in 2 other cards via a PCI-e 4 way splitter so now I am running 8 gpus on this board. In addition to this, 2 of them are different models from the other 6. I am running 6 rx 580 4 gb, 1 rx 480 4 gb, and 1 rx 570 4gb. They do NOT have to all be the same card.

Used to replace the A version in a more simplified application. It’s pretty nice but not that easy to install. Some of the pin locations are too different from the A motherboard which makes no sense, since it’s supposed to be the same board with a few less features. Regardless it works just as well as the A board it replaced.

Wanted to provide a recent review for those who are considering this Motherboard for mining. I can confirm that mix manufactured cards (Nvidia and AMD) in the same rig will not work. Otherwise Same card models will. I have 6 x AMD 6700XT running Pretty close to 47/MHs. Still messing with settings. I am running my mining setup on Windows w/Team Red miner. Like previous review, Update BIOS to latest version (3004). In bios, just reset everything to default after update (F5). Use F9 for search, type 4G -> Enable both. Change all PCIE speeds to GEN2, Disable Audio, Serial and SATA ports not in use (I am using #1). Lastly, make sure CPU is being used as default graphics display, not auto and disable fastboot. You May need to do a TdrDelay Mod of 8 to 10 in windows with 5 Video Cards Plugged in. My Tdr setting is 8. PCIx1_1 should be the last slot for your last video card. 5 Video Cards works with no prob, once you add TdrDelay w/bios settings, Windows Boot might take 30sec-45 with that 6th card, so just wait for the display to turn on. The video driver didn't fail. 46.6-47.5 MHs is norm for 6700xt on this build. Hope this helps any future folks. Can't comment on HiveOS, I just avoid it, so can't speak to 6 cards with Linux, only windows.

Good Motherboard for 6 gpu mining rig. It will accept 6 but you have to do certain things to pull it off. 1) before you connect any riser or peripheral (just ram/cpu/disk connected), hook it up to monitor (hdmi) and update the bios. 2) after you update the bios to latest, enable "Above 4g decoding" in the advanced section (it's under "system agent (SA) configuration" of the bios (please note if you do this first, then update your bios, it will fall back to 4g encoding = disabled after the bios update). Once you get those options set, go ahead and load up your OS (Windows10) and set it all up. Then you can connect your riser cards to the motherboard, with one important detail, all 6 cards have to be identical (same manufacturer, model, etc). It will not work with mixed manufacturer cards or different models (using the 3/16/21 v2080 bios). As an example 2 gigabyte nvidia 2080's and 4 asus nvidia 3070's will not work, locks up and no video. However if you use 6 MSI AMD 5700 xt's, it will load like a champ (or 6 of any identical card). Another thing to point out, if you have trouble with AMD cards loading the amd adrenaline driver (blue screen's or fails to load it), you have to add a windows 10 registry key to lengthen the wait time for windows to find the card on the riser (google how to add TdrDelay to registry) that will solve the blue screen's. Good luck! and yes I spent about 2 days of trial and error to figure all this out. :) I have 4 (6gpu) mining rigs using this mainboard so it is possible.

Had everything I needed and it all works. I love the M.2 CNVi compatible wireless card slot. I bought an Intel AC-9560 wireless card (requires CNVi) and it works extremely well in this board.Be aware that older BIOS (0605/0805) will not display any video if trying to boot with a Samsung 970 EVOPlus NVMe SSD. I had to remove it to be able to see BIOS/UEFI on boot. After updating to BIOS 1002 the card was recognized and I had video.Also note that this board only has four (4) SATA III ports. It was all I needed but has caught others by surprise.

If you get a black screen upon first boot be sure to remove cmos battery for a while 10+ minutes to reset everything. It should then be able to boot into bios. I knew my first board was faulty though because my cpu fan wouldn't even spin, replacement came in quick within 1 day. Enjoy, it's a good board for the price, you can't blame the manufacturer for wear that could happen through shipping, especially with delicate components.

Wanted to pick up a cheaper board when upgrading my CPU, read the reviews and this matched what I needed. However when it arrived I was disappointed in the quality, even as a cheap board. Mine shipped with 3 total screws; so while other made a point of saying it only has 6 fasteners opposed to the 8 that are normal, mine had three tiny screws to keep it attached to the case. With that being said, I wasn't able to mount the board properly and had to find previous hardware. While mounting I noticed the heatsink (I believe CPU heatsink) was very, very wobbly. I have yet to turn my rig on as I'm waiting for the CPU to arrive, but I am not holding onto hope that this will work well. Might update review if things work out, won't update if the thing doesn't work properly.

Got this board used - like new, and it looked brand new. No problems installingThe board itself is very good. Room for 4 RAM sticks, 2 M.2s, and 2 GPUs. Can’t really ask for more
