Hi,
I have couple of questions and it will be nice if someone can answer.
Does anybody use PCI-e Express 1X to 3 Port 1X card?
Does it has any effect on mining speed?
How many gpu we can have on Win10? Win7 and Win8 have limitation on number of gpu.
Does Claymore miner or OpenCL have some limitation on nuber of gpu?
I use it with ASrock H81 Pro BTC board, it has 6 PCI-e slots, one of which uses this splitter, and two cards are connected via it. So 7 cards in total. All 7 are Sapphire RX470 Nitro+ 4GB Hynix memory, and all 7 mine at exactly same ~212 Sol/s. This rig uses Windows 10. I've heard Win10 can use up to 10 cards, I do not know. I had issues with RX470 cards with Win7, no patch helped, 5 cards were maximum, the rest did not work at all (even 6th). Now I use Win10 To Go booted from USB flash, and it works perfect. It also works great with Linux. No drivers were installed by hand, Win10 found the PCI-e bridge automatically and installed GPU drivers.
