Anyone know where to get WORKING M.2 NVMe to USB-socket PCI riser stubs?
I bought a bunch off of Amazon, $1.78 shipped ea., bought a qty., tried two, one in each M.2 NVMe slot on a Asus ROG STRIX B450-F ATX AM4 mobo, neither one worked, but the riser worked fine with a normal stub in a regular slot.
I just built this this morning, using a 6-GPU server case (came with an additional 8-GPU plate). What makes this server case unique, is that the mobo has the standard I/O and slots available, as well as the GPU mounting plate(s).
So, because I'm using an AM4 mobo, and you need to use a Ryzen CPU with that to get all of the PCI-E lanes, and Ryzen CPUs, don't have iGPUs, I'm using a Zotac 2GB GDDR5 card on the mobo's primary PCI-E slot, on the mobo expansion slots in the chassis, and then using GPU risers on everything else. But that limits me to 5 additional GPU risers, unless I use both NVMe slots, with USB risers, then I could potentially utilize 7 cards, in addition to the Zotac.
Maybe I should have put in my Gaming X GTX 1660 ti card, that would have been a better choice for a mining rig, probably. But the Zotac card is short, and that helps with the wiring. I took out the middle fan plate that normally sits at the edge of the mobo area.
I've got 2x Asus and 2x XFX Raw II RX 5700XT cards in there now, and in a pair of other PCs, I've got some refurb RX 5600XT cards that I want to put into the server, to max out the six card slots.
