SLI question ...Two differnet 1080 Ti

[brighttail]

So i have an MSI 1080 TI FE... I'm looking to get a second and found a good price on the EVGA GeForce GTX 1080 TI SC Black Edition.  Now if I'm reading correctly what I'm researching, this EVGA does use the same reference PCB as the Founders Edition and should accept an EKWB the same as my FE card.  There shouldn't be any issue of running them in SLI is there?

as far as i know, no. I dont think you would have any problems.

Its the same with ram (this is a bad example but its the same principle) it doesnt matter which brand of ram you buy, as long as it is both ddr3 or 4 or what ever. or the same ram speed

SLI works on different cards of the same processing chip...

That is what I figured but for example the same EVGA card that is the SC2 Black, I believe has a different PCB, and probably a different type of chip and I was seeing people say THAT card wouldn't work.  The weird thing is both the EVGA cards can use the EK-FC waterblock it seem.

No every 1080 Ti card uses the nVidia GP102 processing chip, if it has a different chip it is not a 1080 Ti and this is the only thing that matters for the SLI bridge to work that it's the same chip... PCB and cooler aren't needed to be matching... then again I am against having an open air cooling card because its thermals might interfere with the other card and make all hotter... I'd prefer having 2 blower style cards so all the hot is pushed away from the case.

I watercool them anyway so I'd be taking the fans off anyway. BTW finding blower type GPUs is difficult as they are 2x more expensive in many cases than cards with multiple fans, due to the cryptocurrency mania.

If what you say is true I might consider another 1080ti that is cheaper but one that I can still get a EK waterblock for, they won't be exactly alike but close enough from the exterior... hmmm decisions.

Personally speaking considering you'll go all in with the water blocks I'd just buy the cheapest possible that's compatible indeed, truth be though the one thing that matters most with Pascal architecture cards is good thermals due to how GPU Boost 3.0 works, "overclocking" is more of a matter to have the card as cold as possible.

 

Better VRMs, Capacitors and what not you find in cards like the Hall of Fame might help you squeeze additional 50~75mhz but in real world this is negligible performance gains.

As I'm using it in SLI on a 4k monitor all i care about is rock solid 60 FPS   Also we'll see what happens in the future with the new 4ks but I think that is a year down the road before they have the 144Hz up that will not be stupidly expensive.

[brighttail]

heh nm... many problems with that card.

Yes it will work just fine! Until the SC2 burns it's VRM's up, the card dies and you wait a month for a replacement, because they haven't been produced in five months, and you're waiting on EVGA to send you back another 1080Ti SC/SC2 that'll have the same problem because it's a repaired refirb card.

LuL! sad but true...
