Can I run mini gtx 670 with a normal gtx 670 (680 pcb)?

post #1 of 8
Thread Starter 
I have a gtx 670 KFA2 thats has a gtx 680 PCB. I am looking to go sli and I am looking at potentially running my 670 with a gtx 670 that has a mini pcb. WIll I encounter any issues in doing this?

My 670 runs at 1306mhz, so I figure im gonna need to downclock that core speed if the new 670 doesnt run that high, apart from this will I encounter any more issues? Ive never been SLI before and im looking ti improve my minimum frame rates im getting on BF4 at 1440p.

thanks all

there should not be any issues.

also i would think you do not need to down clock any of the cards

Well as long as the smaller 670 has all the SLI capability etc. I don't see why not. You would need to have the cards running at the same frequencies though.

I thought as much. Im planning on buying a second gtx 670 since my minimum frame rates in BF4 at 1440p dip low sometimes, I dont plan on having AA on so im guessing the fact the cards are only 2GB wont make a difference.

Yep two different GTX 670 models should work fine together, haven't ever heard of a problem between different models crossfiring in modern series cards. (Fermi, Kepler, Maxwell, 7xxx, R9 series)

No not really. You might hit the roof very occasionally but that's nothing to worry about. Honestly, at higher resolutions AA has less of an impact.

I tried AA on and to be it made little to no difference, but when theres a lot of stuff happening my frames drop right down.
