Sli corespeed

[shadowkiller64]

Do i have to have the same corespeed for it to sli?

I'm pretty sure it matches to the core speed of the slowest card automatically.

[Rorgash]

doesnt Nvidia demand it being the exact same model of card aswell?

 

so unless you OC one they should be the same

Correct. All cards will scale down to the slowest card. So if both are OCed to 1.2Ghz, no worries. But if one is 1.2Ghz and the other is 1Ghz, then the faster one will scale down to 1Ghz.

Different manufacturers have different clock speeds

;_; i have a 560ti msi hawk and a 560 ti ref ;_; the hawk gona scale down to the ref Q.Q

OC the ref. Problem solved.

OC the ref. Problem solved.

the problem is that its a ref... they kinda have poop cooling

[shadowkiller64]

OC the ref. Problem solved.

another problem i dunno how to oc graphics cards

MSI Afterburner. There are plenty of GPU overclocking guides on the forum here Not to mention countless YouTube tutorials. GPU OCing is rediculously easy.

The ref cooler should do a decent job.

the stock clock on your MSI will be really low anyhow, even factory OC'd cards tend to be incredibly low...

Um no.

 

It doesn't match itself, both cards will boost, if one is faster than the other and has a higher boost clock, it'll run faster than the other.  You can OC in precision X/ afterburner etc at seperate rates as well, and both cards will boost completely differenetly.

 

 

In this pic, card #1 1163, card #2 1150

 

 

@Rorgash you can SLI any card as long as it has the exact same GPU chip.   (780 with only 780, 770 with only 770 etc)

I thought SLI/Crossfire was the technology of having two cards run parallel. In order to do so, you need the same architecture on the card, and they run the same thing (hence why VRAM doesn't double). So shouldn't they if one is OC to a best clock, it will just match the other?

They run parallel, but they don't have to be the same speed. You can have one card at 1000 mhz and the other at 1400.

 

I'm not entirely sure how the inner-workings on the actual hardware+ software level work (not the dumbed down version that we see on tech-quickie or other variances)
