ASUS B650PLUS Unable to detect 2nd GEN4 M2 stick

If it isn't showing up in the BIOS at all then there isn't a lot you can do. It seems you've already ruled out the board by moving the OS drive to the other slots which prove they work so it all points to the new M.2 drive being the issue. Either both are DOA (not impossible but unlikely) or they have some sort of compatibility issue with your specific combination of hardware.

I don't think your board has M.2 slots that share bandwidth with anything else so there shouldn't be any settings to tweak. It should just work really.

Honestly at this stage just get a different brand / model of SSD from a reputatable source and see if that works. That will be the simpliest solution and then if that works just return the SK Hynix drive.

Yeah I think you are right. I've not got a lot of options at this point. I'll get a Kingston M2 as that's what the OS is running on.
Thanks for all the help and happy new year.
 
I have now replaced the Hynix M2 SSD with a Crucial T500. It's now being detected in BIOS and OS when I 1st place the card in a M2 slot. I can install games on the drive no problem. However when I reboot the M2 SSD is no longer being detected in BIOS and therefore OS. If I change the slot that the M2 SSD is located it will detect it in BIOS and OS upon 1st boot. If I then reboot the machine it isn't detected in BIOS and OS? WFT??

Are you back on a stable BIOS version?

Some Asus boards got a BIOS update a few days ago so might pay to check if there is one for yours.

Thanks, just checked and there is a 2214 new version out. I'll get that installed and see if that fixes it!
 
Ok so updated the BIOS to 2214 booted up and no additional M2 SSD detected. shutdown, swap M2 slot and reboot. The drive is detected in OS etc. Same pattern as per pre BIOS update.?
 
From what I understand two of the slots use CPU PCIe lanes and one uses the chipset PCIe lanes. The two CPU ones are the top and the bottom left. So if you are swapping between the bottom two slots that kinda suggests a board issue rather than a CPU problem as logically if it was the CPU the bottom right would be unaffected.

Assuming a BIOS reset with the battery out and power cord disconnected from the PSU for 5 minutes doesn't help I'm kinda out of ideas. I would suggest contacting Asus support to see if they have anymore suggestions or RMA / replace the board.

I am not entirely sure how the lanes are configured on my mobo. Not sure this diagram tells you either. But I agree I think its deffo a mobo issue and I'll be forced to RMA (although I think the board is over a year old so not sure if I'll get a free replacement?)

I was talking specifically about your board. If you scroll down from that diagram to page 1-4 it explains how they are divided.

Asus boards should come with 3 years warranty so you'll be covered. Might be quicker to go through the retailer but see if Asus support have any other suggestions first or maybe make a thread on the Asus forums as some staff / very knowledgeable people lurk there.

oh right I see. Thats good about the warranty (I bought via Amazon so I guess they'll be ok?) thanks for the advice

If that is the case and if you get no useful suggestions from Asus support etc I'd live chat with the retailer and say it's faulty, say you've contacted Asus support and they say its faulty. That way you should be able to return it for a replacement / refund without much messing about.
