[quotemsg=14754328,0,1837469]"Since the hose side of the bridge only operates in x16 or x8 mode, total bandwidth drops to x8. Those eight lanes are still repeated to four slots, but “x16” mode for two or fewer cards only exists on the device side of the bridge whenever Ultra M.2 is utilized in PCIe mode."
What does this mean? On the Asrock mobo if I run a x4 m.2 ssd in the ultra slot how many lanes will my 2 GPUs run 'at'? 16/16, 16/8, 8/8, or other? And if I only run one gpu will it run at 16 or 8?[/quotemsg]Should be "host" side.
Anyway, if you install an x4 SSD the slots will get x8 bandwidth, x8/x8 bandwidth, and x8/x8/x8 bandwidth because the bridge is a repeater. That's the short story.
The long story is that two of your cards will be detected as having x16 connections because that's how they'd connect to the bridge.Its as if you lived on a 2-lane street that opened up to two more turning lanes where it crossed a main road, then the google van drove by and took a snapshot of those four lanes and registered it as a 4-lane road.
