If nvidia-smi doesn't see it, then msieve won't. Perhaps you need to reinstall the CUDA driver with the M40 installed?

Reinstalled driver and CUDA in different variations and no joy. The computer says it's there, but CUDA says it isn't. I put the K20Xm back in and it sees it every time. Both are PCIEx16 v3.0.

Giving up for now. . .

ETA: Msieve compiled with 5.2, but couldn't find the cqard, as expected.

Thanks for the help.

I guess I have found my answer for the M40:
Code:
[ 1562.849818] NVRM: This PCI I/O region assigned to your NVIDIA device is invalid:
               NVRM: BAR1 is 0M @ 0x0 (PCI:0000:01:00.0)
[ 1562.849819] NVRM: The system BIOS may have misconfigured your GPU.
[ 1562.849824] nvidia: probe of 0000:01:00.0 failed with error -1
[ 1562.849839] NVRM: The NVIDIA probe routine failed for 1 device(s).
[ 1562.849840] NVRM: None of the NVIDIA devices were initialized.
And, no newer BIOS updates addressing any PCI issues.

That's a BIOS issue. Google says to look for options deep in the BIOS menus like PCI Express 64-bit BAR Support, large BARs, or above 4G decoding.

Thank you for all the help with everythig. I do appreciate it, but I'm going to leave it sit for now. I did search the BIOS and all I found were two things: a Robust Graphics Booster with Auto/Fast/Turbo setting, for which there is a red message (for all three settings), "Warning: VGA Graphics card is not guaranteed to operate normally," and a PCIE frequency adjustment with a warning about setting it above 100MHz. The messages are displayed for the K20Xm as well. I guess I should consider myself lucky that one works.

Thank you, again, for all your help.
