I picked up a Dell R720 recently and have been pretty stoked about its performance with dual 2670's. I upgraded to the NVMe hot-swap option that consists of a 4-port card that splits the PCI-E x16 slot 4x ways and connects to a hotswap bay in the front for 4x NVMe drives. Pretty freaking cool! Except when I benched my new P3700 it maxes out completely at 1719mb/s read and write. Not that that's slow or anything but I expected more. Come to find out that 4x breakout card seems to be limited to PCI-E Gen2. I would LOVE to be proved wrong but this sucks and I can't find any options in the BIOS to force things to negotiate at PCI-E Gen3 speeds. The Dell card part number is 0YPNRC.
Does anyone else here have a Dell R720 with the NVMe hotswap bay option that could verify that this card is indeed limited to PCI-E Gen2?
