So I've read that 13 GPU's are max on one Rig. And that this is because this mining motherboard from AsRock has 13 PCI-E 1x slots. But now I've come across this:
Windows has limited max 8 GPUs on the system, and Linux (13 maybe). But with a few trick, we can add more than 8 GPUs on Windows.
This (as I understood it) allows you to put 4 GPU's per 1x slot. Wont I be able to user 4x13=52 GPU's per rig then?
People out there even try so hard to set up 10-13 GPUs. And stability issue will be the main problems for broke the limit.
Actually Windows 10 can add upto 12-13 GPUs, just update to 1709 version. To check Windows version Run>winver
