Wouldn't it still work without the bridge? I realise it'd be awful performance wise but souldn't both cards show up anyway? Are they both in device manager, sorry if you've already mentioned it.

HI Guys i do a lot of video editing as a hobby, After years of using Gtx 670 i upgraded to what i am assuming it the top notch for what i can fit in the case.. So got two pny Geforce RTX 2080 Ti's blower (due to space restrictions ie m/b layout and additional card in there) with the idea of sli'ing them together... So got me self a Nvidia geforce RTX 4 slot bridge, It came today, so i put on the bridge turned on the machine and Wham Bam no way option to sli. Them, What the chuff have i just wasted nearly £100 quid on this or am i missing something. Is the bridge not compatable or ???. Any insite would be very welcome..

Thanks

update your bios, what CPU and MB are you running ?

also check GPUZ to see how many PCI lanes each card is using as you need at least 8x on each card for SLI support.

Its an asus p9 x79 pro (its at least 5 years old) with a Xeron E5-2680v2 All the Pcie are v3 with 16X slots as to the manual instruction.. BTW thanks i realy appreciate peoples help on this i am coming to the conclusion the boards too old.. :(
 
So, board has 2 x 16 PCI-E slots and supports SLI, it's also previously run SLI with old 6 series cards.

PSU is plenty.

Both cards recognised.

Whats left? Another bridge/try different slots/reinstall windows?

That motherboard supports SLI. I wonder, though, if you need the GPUs in the two top-most x16 slots?

The cards are in the 1st and 5th slot

Is the other add in card in slot 3? going by the manual slot four would be better as 3 would knock the lower slot down to x8. SLI would still work in that case though.

I'd update the bios of the board if it's not the latest.
Ideally try the cards on a different board.

It could well just be the bridge. I had problems in the past with the old crossfire bridges.
 
@John73

The bridge should light up like the one in the pic below.

Also try removing and refitting your cards as they don't always seat properly.

Make sure you have the latest bios for you motherboard as these cards are not using ordinary old fashioned SLI, NVLink is different.

Install the latest drivers and SLI should be enabled by default. If is not set by default choose 'Maximise 3D Performance' in the NVidia control panel.

Also check both cards are working by moving the output cable from one to the other.

You can't really put the cards into the wrong slots with that board as you use both blue slots for Sli and his cards are in them.

I think Kaapstad has nailed it and the Sli bridge is faulty as it should light up.
 
That's gonna have 1 hell of a cpu bottle neck might be better of selling a 2080ti and upgrading the core system
 
Logo does normally light up have you removed and reattached the bridge from the photo the bottom card and bridge don't look properly aligned? If it is attached properly and both cards are in x16 or at least x8 PCIE slots then it should be working as you know.

No, you get a warning to attach a bridge or at least I do. Never seen SLI work without a bridge.
 
Thanks guys for the many people who are helping me its very much appreciated, I have been maxed out on the number of posts that i can put on... by the forum. I have ordered another bridge by EVGA this time that says it's compatable with rtx 2080ti .. so waiting for that.. So hope the one i have is faulty. As many said it should be lit up and its not even doing that..
 
A few hours after that i got my other bridge and fitted in and again northing. So i took out the cards and reseted them, Still nothing then i thought its like no power so of the top of my head i just thought i would swapped the two power connectors from left to right sockets in each card and a bingo it lit up... Shame i have a spare one now so if anybody want it for £50 quid let me know. LOL. But really do appriecate all and everones advice.. Nice to know how helpful allot of you are.. Thanks guys... BTW I think it runs better with SLI disable LOL .. :D
