SLI Crystal Link Question

R-TYPE · 4 Apr 2015 at 22:40

Am trying to connect two 980gtx hydrocopper cards from EVGA (they come with ekwb blocks), on a Gigabyte Z97X-SOC Force motherboard in SLI. Motherboard manual states to use PCI slot x16 and slot x8. These slots are separated by slot x4. I plan to use Crystal Link to connect them.

Face to face of cards is 60mm approx. I think I therefore need Crystal link 4-slot, however the Crystal Link 4 slot contains a 55mm tube, whereas the 3-slot contains a 47mm tube. Link to 4 slot below:

i think i'm crossing 3 slots from a card in pci slot 1 (16x pci), passing over pci slot 2 (4x pci) and connects to the second card in pci slot 3 (8x pci).

am confused by the crystal link packaging diagrams in relation to 3 and 4 slots. the question: is this considered 3 or 4 slot spacing for the crystal link?

photo of the cards installed with two bitspower c47 multi link adapters installed , shown on the spoiler link below. card on the right is in pci slot 1, card on left is in 3.

Can anyone advise?

Many thanks

To answer my own question, have found this diagram from hardware asylum:

I think I've been confusing the definition of slots. I actually need the 4 slot tubes, as the cards are in Slot 1 and 5, not 1 and 3 as I incorrectly posted above. I had not counted the smaller intermediate PCI slots.

For 2x EVGA 980 Hydrocopper cards on this Gigabyte Z97X-SOC Force motherboard, with c47 Bitspower G1/4 multi link fittings, I needed the 55mm tube for the connection, from the Cross 4-Slot pack of tubes (actually have two as am going for a parallel connection between the cards)

Thanks Harry, got these to work at 55mm

Is this wrong? Only done the fitting so far, have not competed the loop as of yet or filled with water for leak tests.

yeah def got the 24 pin adaptor before I do the leak test! Just waiting on the lastest of the last fittings to come through in the post before I start the loop phase.... frustrating waiting. They're like the last 0.5% of the job.... and they're out there somewhere in the postalsphere....
