Yes, that's what I did, one by one until 7. Then at 8 it starts to freak out, and going to 5 cards
Hoping to see if anyone else succeeded. Cryptomined on Youtube did a video on
8 gpus on Z270-P with RX 580 but he's using some 1 to 3 pci splitters, which I never got working in my case.
Not sure exactly which version of the splitter he has, only that he only uses 2 risers in each 3-way splitter. I saw someone with a 4-way splitter using all cards. Is Cryptomined here on bitcointtalk maybe?
But none of the cards really have any brands so it's hard to find the exact right one, and even if you do, it might be DOA
Dunno mate, never used the splitters as success seemed to rely solely on luck lol. I did not see many miners using them. This is why I went with the Prime A and not the P because I knew it would natively accept 8 GPUs with an M2 adapter. It was really a no fuss install.
I think you can reach cryptomined on the zcash forums pretty easily per PM (I was actually reading a thread on the zcash forums where he was talking about being reachable through there).
I would either stick with 7 GPUs on the P and mine away or return the board and pay the few extra $$$ for the A. I know how frustrating it is sometimes to want something to work, but you end up wasting so much fucking time trying that in the end, it's just not worth it. I had such an issue with an asrock board once, I think it was a z97 anniversary or whatever. It had a total of 6 pcie slots and I got it working with 6 GPUs after a lot of trial and error (and luck probably). Then I wanted to upgrade the drivers and it just fucked it all up. Never got 6 cards working on it again. As I knew it was a pain the first time, I spent maybe 30mins trying but eventually just replaced it with a spare pro btc which worked immediately.
Your own time is money too you know :p
