The PCI-E slots in something like an 1U R630 or R640 are x8 or x16, the problem is more with the cooling and size/shape of the cards and how they cool themselves. The slots are meant to be used with things like 10 or 100 Gbps network cards or SAS/SATA host adapters which are considerably lower wattage than even a video card that's much weaker than an intel 770.
Commonly you will also find configuration with two or three 'low profile' pci-express slots which have a different card height than the 'standard' height that most GPUs are built at.
- genewitch 2y agono, i mean like this https://www.youtube.com/shorts/rTCInAXSzKA https://www.youtube.com/shorts/rTCInAXSzKA that works for crypto because all the CPU sends to the card is the target ledger sha256sum (simplified) and the GPU generates nonces until the `sha256sum(sha256sum(nonce += ledger sum)` has however many zeros in the front. So until a card finds the correct nonce, or the server sends "new work" - a new ledger shasum, there's no traffic, really, between the GPU and the CPU. housekeeping, whatever, but not like 1GB/s!
