So it begins! (3960x + custom liquid cooling)

The system doesn't detect the card at all. In the bios, the PCIE slot registers as empty.

This sounds to me like you are booting with another card in the primary PCIe slot with the 1080 in a secondary PCIe slot? I wouldn't be surprised if it doesn't register in the BIOS. But if you can get into the BIOS, try disable CSM (compatibility support module). And after doing that, put hte 1080 back into the primary slot to see if anything changes.

Actually it was in the primary slot, but I had a second GPU (the rx550) in the other x16 slot with the display attached.

I think I remember seeing something like that. I also tried a few different settings (like forcing pcie gen 3) etc without luck. I'll give this a go.

Nope, same outcome.

 

Edit* I found an evga card within tube distance in london on ebay for £230. I'm picking it up this evening.

The evga card works.

 

I have seen many reports of 10 series cards not posting in various motherboards and a disproportionate number of those issues seem to be with MSI cards. I pretty sure they just guffed up the bios on these cards somehow. Oh well, I suppose I'll just include a note and a return postage label with the card when I sell it.

 

Here's the system now:

Not without some more issues though (why not?).

One of the things I wanted was fan control via coolant temperature. Fortunately the board supports this with a couple of headers for 10k thermistors. For reasons that defy all logic and sense though, certain fans can only be controlled by certain sensors. The sensor that suited my needs however, was sandwiched between the edge of a usb2 header and the bottom-most PCIe slot.

I ended up having to solder some new leads on that would fit in the gap:

Can't say I was thrilled about soldering this close to by far the most valuable computer I have ever owned, but hey ho. It had to be done. I'm sure the cardboard will protect it from the 250 centigrade molten metal 😆.

Time to get an OS installed 😉:
