Question about SLI overclocking.

[quiffghtyu]

Say I have two 1070's in SLI, and I decide to overclock both cards. As we know, the chances of both these cards being able to overclock to the same standard as each other is very low/impossible. So hypothetically I get +100 core on one card and +200 on the other, would this cause any sort of performance issues? This may have a very simple answer, making me look rather stupid. But I have just been wondering about it.

 

Thanks

i think they have to be at the same speed for sli to work at all. might have changed however

Seems to make sense. I know very little about SLI and have never had an SLI setup.

From my understanding, it won't cause any problem at all, but it also won't perform any better than if you had both at the same clock (+100/+100).

I would've thought that if one is working faster than the other, then one might fall behind? Causing crashes and frame drops etc etc?

The cards will operate at the speed of the slowest card.

 

Say one 1070 does 2000 core and the other 2100 core, both cards will run at the lowest clock (2000 core).

For best performance you should keep the clocked the same, you can overclock them to different levels but one GPU will just sit there waiting on the other and you could see lower/less consistent performance

Right ok, makes sense. Thankyou!

I can run my cards with a 300 MHz difference. Won't matter. Will never crash. May have slight stutter but I never noticed it. Did it for months actually. My cards are now hard clocked, so they have to clock together, no way not to.
