Hi,

I recently bought PCIE 1 to 4 expansion cards from below.

However, on my old system with chipset X58 and also on new H97 chipset, only maximum 6 GPUs working. I tried every possible settings in BIOS but no luck getting more than 6 GPUs working on any of these chipset.
I am now thinking to move towards newer chipset like B250. If I purchase lower end mobo. with 1x PCIE 16 and 1x PCIE1x slot , will it work? Do newer chipset support 8 GPUs? I am not talking about special mining motherboard, just a regular one.
