Overclocking ASUS GTX 770 SLI

[Leifaklard]

Hi.

Yesterday i overclocked one of my GTX 770 using ASUS GPU Tweak. I disabled the SLI and tested the new settings and the results were awesome! But, when i try those settings with SLI, the PC just froze...

The settings i tried solo were:

GPU Boost Clock: 1250
Max GPU Voltage: 1212
Memory Clock: 7900
Power Target: 110%
GPU Temp Target: 94º (The card didn't reached 75)
Fan Speed (80%)

Its the first time i tried to o.c. this cards, and its just for the fun of it, but i really want to try the two o.c. in SLI.

What am i doing wrong?

The reason that it froze when you tried the settings in sli is that the other card can't get those clocks speeds (over clock ability all depends on luck of the draw) and one of the cards can't get those speeds

The other card can't get those speeds? They are identical...
I've tried other configs and it freezes all the time.
SLI and overclock don't combine, is that it?

the cards are not identical each has a different die on them and no two dies are the same every die overclocks different than any other die.
SLI and overclocking do work together but if one card cant run at a certain speed it will be very unstable.
