We recently acquired a HP DL 585 G6, fully populated with SAS drives etc, we want to use a PCIe SSD and have brought an Asus RIADR Pcie SSD however the bios fails to recognize this, can anyone suggest things to try?

That's the official answer from OWS, now another answer if it is possible to force hp controller to up it to x2 width, that will require some more research. -)
All PCIe NVMe cards are PCI v3 (or later), although the PCI NVMe standard does allow for x1 connections the majority of M.2 are x4 connectors, in fact I'm not sure there's a physical connector defined for >x4 lanes, M.2 is a physical specification definition for a device capable of both SATA and PCI NVMe drives, some motherboards will not support NVMe at all, some will so to some extent and some explicitly support it - it depends on the system board specification, your BIOS needs to support it - just having UEFI does not ensure NVMe is supported, 'lower risk' than what exactly?
Also your statement about PCIe v3 working in any v2 slot is incorrect, I'm sure one or two may but that's the exception not the rule, the opposite is true though, v2 adapters will almost always work in v3 slots.
Best Answer
Use a supported PCIe SSD.
Your problem is likely due to the hardware not addressing the PCIe x2 interface correctly.
To verify the situation, look in the Rom-Based Setup Utility (RBSU - press
F9) bios screen and see if the card is detected. If it does show up, then your issue is at the OS level. Update your server firmware if you haven't already, just to make sure.The HP ProLiant DL585 G6 was released in 2009. It's old enough that this particular card may not negotiate speeds properly, or simply may not be usable. I would suspect that it be visible and would just drop to x1 speeds, though.
More details about your OS, any error messages and whether the card is known-good would be helpful.
