Title: narrow height 1080ti or 1080 cards (1 to 1.5x vs 2x height)?
Post by: mindsignals on January 04, 2018, 02:34:07 PM
Are there any 1080ti or 1080 cards that have narrower heights (single to 1.5x rather than the typical double-slot height)?  I have a ROG V Extreme with 4 slots and currently run two 1080ti cards with sniffdogminer in slots 1 and 3 for heat dissipation. I'd like to run cards in slots 2 and 4, but used to have 780ti in slots 1 through 3 and that second doubleslot would overheat as there was literally no space between those cards.  Thus, I'm looking for two with lower height for slots 2 and 4.

Also, can I run sniffdogminer for cards on slots 1 and 3 and another multiminer for cards on slots 2 and 4 simultaneously if those other two slots run just 1080 cards or do I need to run 1080ti cards in all four slots and use just the one miner?

Finally, am I able to use the m.2 slot for a graphics card (either in addition to or in place of one of the pci express slots)?

You can set the gpu groups in mining software. At least it's true for Nemos-miner and Megaminer, I haven't tried Sniffodgminer recently.
There is really no way to dissipate ~1 kW heat from 4 1080ti cards in such close space. And I don't think there exist any single or 1.5 slot 1080 cards unless you buy an aftermarket fullcover water cooling.
Just use pci-e risers and build/buy a frame for your rig.

they do not need the room

I am assuming you have an open case  not a closed case.

Currently, I have it closed, but assuming I go to 4 cards, I plan to leave it open...I didn't know about pci-e risers...I'll definitely look that up. This rig won't have water cooling, but I hope to add another rig expressly for mining this spring or summer. For now, I'm looking to make this a 4-card system. On my son's 1080, I run nemosminer...that's what I'd plan to run on slots 2 and 4 if I add 1080 vs 1080ti.

Thanks!

For the 1080 or 1080 ti, about your only options to run 4 cards on the MB on that MB is to use hybrid or water-cooled cards, if you want decent cooling.

Even a 1080 running at "efficient" settings around 105 watt ballpark with AIR cooling is going to have heat issues when the cards are crammed in that close.


 You also need a case specifically designed to have "8 slots" in the back for GPU slots, or you won't be able to run any sort of a double-slot card in your Slot 4 at all.
