No NVLINK option in NVidia Control Panel ?

[JezUK]

I've just installed a 2nd RTX 3090 into my workstation, along with the NVLINK connector to bridge both GPUs - and both RTX's are installed in x16 PCI slots.

However, when I go to my NVidia Control Panel, I don't see any options to enable SLI/NVLINK etc.

Yet, my mobo, apparently supports it (Asus Sage X299).

My test render times look reasonable (this 2nd card has reduced render times from over 13mins down to 6mins 30s) - so I'm wondering/expecting if NVLINK were connected, I'd see better results ?

....probably because there needs to be a monitor connected to the 2nd gpu.....

Yup, look for one of those Dummy Display ports, it will do the trick for you

[francomanko]

you need to attach a dummy display to get it working?

How did you get your hands on two RTX 3090? Everywhere I look they have been sold out. Worth the $?

Or you can stick the 2nd monitor (or 3rd) into the 2nd GPU.

Very lucky I guess....

they are going for obscene prices on eBay.... £1400 to purchase, selling on eBay for £2500..... crazy...
