Topic: Anybody tried to mine with 18-24 GPU's? (Read 514 times)
i prefer to keep my rigs to 4 or 5 gpu's per board. much easier to troubleshoot and to keep stable. anything more than 5 i found gave stability problems and i was constantly having to restart miners. thats my personal take on it
Do any mining sofware work with 18-24 GPU's?

The expansion kits will not work as effective as you believe. With an expansion kit there are 3-4 slots available but currently issues with it and you will only have 2 slots working. So in reality with an Asus z270-a you can put 7 expansion boards and 2 m.2 to achieve 16 GPU's but you are going to have many issues to try and save a little by doing that. Your better off getting a high PCIE board and building multiple units to not worry, especially if you are building this for a house as you would need 30 amps atleast, or a 240V plug. Best off getting 2 750W Psu an Asus z2700-a and running 9 cards on thatm, and building 2 systems for 18 GPU's.
I wouldn't say it's impossible.
I would say that it's likely not worth the trouble with a typical consumer motherboard, given current limitations of most operating systems and drivers. With the amount of time you'd put into trying to make it run, you'd probably be better off building one or more additional rigs and being able to mine during the weeks (at least) it'd probably take to get an 18-24 GPU rig fully operational. Additionally, if your motherboard/CPU/etc. were to fail, all of your eggs would be in one basket, resulting in downtime for all cards.
If you're doing research on how many GPUs you can put into one rig, keep in mind that such attempts have been made for various applications other than mining (which I assume you've already been researching). Certain big distributed computing projects (such as Folding@Home) have some users with big GPU rigs (although most users don't modify their systems just for those projects). There's also big GPU farms for other purposes, although I don't know how well the setup process for those types of things are documented.

Older thread, but it shows it was once possible to get 18 Nvidia cards running, albeit with some dual-GPU cards instead of the expansion kits that you're looking at.
