I've been upgrading my 2010 Mac Pro 5.1 this year, thanks to all the guides and experience sharing on this here forum. ?
Last month I bought an IO Crest to run 2 x 1tb Sabrent NVMEs, however, despite eventually getting it to run stably in slot 4, I couldn't ever get it to boot in Slot 1 so have now sent it back to Amazon (phew, thanks for their easy returns!)
Upgraded to a Sonnet M.2 this week, figuring the Mac support worth it. It is running stable in slot 1, however only One of my Sabrents is visible?!
Reinstalled the IO to check both SSDs worked - yep, one AND two visible and accessible. Erased both back to APFS.
Re-installed to the Sonnet (quite a pain to install, requires moving fan each time) and SSD Two still nowhere to be seen. 3 days on. Multiple PRAM resets... speaking to Sonnet but they are being pretty slow in their responses.
Recent side development (yesterday), hopefully unrelated, is that PCH Diode / Northbridge is /was running hot eg 80C. I heard a strange ping and suspect a rivet has gone. I Now have Mac Fan Control monitoring and keeping the temp between 55 and 70C. Replacing thermal paste and rivets next week - should have done it when I did the CPUs last month!
Any suggestions gratefully received....
