Folding Forum

I've got two gpu's folding in a Z390 board. As I understand it, Z390 should allow each card to run at x8. But instead I've got one card running at x16 and the other running at x4, I'm guessing off the PCH. I'd expect this on an H chipset, but not on Z. So two questions:

1) Does it matter?
2) Is it fixable?

Also, on another topic, is the RTX2060 still the best value folding card?

Thanks.

1- Maybe, x4 on pcie 3 can probably run most maybe even all cards without bottlenecking, or at least very little.
2- There is likely an option in the bios somewhere to choose, depends on your particular board, might be stuck at x4.

there should be three PCIE slots. the top one is x16 if used alone
the second one down is x4
the bottom one is x8

which slots are you using and which exact board.

There are only 2 x16 slots on mine. It's an Asrock Z390 Pro4. After doing some research, I'm starting to think my board may be incapable of splitting the pci-e lanes into x8/x8. I thought that all Z390 boards could do this, but I found a post on another forum where someone was trying to do SLI on the same board, but getting x16/x4 for their gpu's, and then discovering the board is incapable of SLI. I'm assuming that means it's incapable of x8/x8 for any reason.

2 x PCI Express 3.0 x16 Slots (PCIE2/PCIE4: single at x16 (PCIE2); dual at x16 (PCIE2) / x4 (PCIE4))
