So I have two 670s in SLI and have them overclocked using EVGA Precision X. I have the sync option on, but the clocks are different on each card. I have k-boost on so both cards are at their "boost" all of the time. GPU 1 is at 1162MHz and GPU 2 is at 1201 MHz.
When I run Heaven benchmark, GPU 1 sits at 1298 and GPU 2 sits at 1328. Neither card ever goes above 70C at any point.
Also is it normal that the max GPU clock offset I can get is +35? I've seen people say the can go above 50+. I don't overheat at 40 but I start getting driver crashes.
Is it just one card really doesn't like overclocking and the other likes it and that doesn't work well when using SLI?
