Hello everyone,
Just got a C_Payne PCIe 4.0 X4 Riser card that goes SlimSAS(SFF-8654) to MiniSAS HD(SFF-8643) to convert one of my U.2(MiniSAS HD) ports to a PCIe X4 Card slot. I am not detecting a device in lspci using both a 7800GT GPU and a TP-Link wifi card for testing.
The motherboard used is an Asus WS X299 Sage with i9-7980XE.
So far my troubleshooting consists of…
- Seating and reseating the PCIe 6-pin power connector for the riser card
- Reseating both ends of the SAS cable
- Trying both of the motherboards U.2 ports
- Trying multiple different PCIe cards including a slot powered 7800GT and TP-Link Wifi Card
- Attempted setting PCIe bus speed to 1.0 to see if it was a weak signal over the SAS Cable
I’m at a loss, don’t know where to go from here. I think I need to order a second SAS cable to see if I just got a bad one but the strange thing is wouldn’t the GPU at least get warm to the touch from being powered up? It’s not, does it not turn on without a link state? It’s fanless so I don’t know how to check if it’s got power.
Anyways here’s some pics and links of the parts used.
Any help is appreciated,
Thanks!
