Heh. I, too, did that for a while, using a flat-head screwdriver, until
I bridged something I shouldn't have. I then found these [7], they cost
nothing, and I don't have to remember which pins are which when I'm
tired.
Your setup looks really cool! I wasn't aware of Open Benchtable, but it
was kind of what I was looking for. If would be wicked cool if they are
somehow stackable.
I wanted to attach more than one card to one host, but that's impossible
in a case, cooling is out of the question. So I got myself a mining rig,
and some ASUS Pro WS X570-Ace motherboards. These have three PCIe 4.0 x8
ports. My main compute cards (3x3090, 3x3080, from a previous time) are
attached via PCIe 4.0 x16 risers, and this all works fine.
I'm selling off the 3080s to make room. That means on that one board, I
could attach three different models. And with QEMU isolation, I should
be able to test them individually, without swapping -- simply by online
passing one card into the VM. Problem is, I'm looking into 3x 7900 XTX,
as I really do need them for compute.
I've also been looking into what could be done with a 19" 4U, because
I'm simply running out of room here. With some hacking, it should be
possible to get at least two cards into a 4U. The hosting providers I've
been looking into wouldn't allow more anyway, as there is a cooling
budget per 4U.
Best,
Christian
