Hey, thanks, can you please post all the other algorithms as well?

It sound's more like advert than a benchmark.

Just curious. It's the first time that I see this riser setup. Where do you connect the other end of the wire with the molex connector?

It connect's on opposite side of USB port

Thanks. Looks more reliable than the ribbon ones.

interested to know if a USB hub can be used to run multiple GPUs while connected to a single pcie x1 slot

was it a question or some sarcasm?

no sarcasm.
my guess is no but ya never know. doesn't hurt to ask

actually i don't think there's any technical reason it shouldn't work as long as your motherboard supports PCIe MR-IOV. from a technical standpoint, i don't think this would be much different from using a passive pci splitter or pci expander. or even any different from a dual gpu card for that matter.

if for some reason it didn't work though, you could just use this with a pci splitter. the usb cables are much more flexible than pci extenders, so you could get a lot more creative with it.
