Posted March 30, 201213 yr Hello, everyone! Yesterday i received MSI HD 7970 Lightning and today i am ready to show some info: Setup: - Intel Core i7-3930K; - Corsair Dominator GTX8 2400 MHz 4х 2 Gb; - ASUS Rampage IV Extreme (bios 0018); - Corsair Force 3 128 Gb; - Corsair AX 1200, 1200 W. -120 degress and 1,6v GPU = 1600/1850 Mhz. Need more time for better clocks, i think it is possible. More photos here: http://oclab.ru/topic/ekstremalnyiy-razgon-videokartyi-msi-hd-7970-lightning
March 30, 201213 yr Nice one Slamm...seem like GPU Reactor helping on your Core..I run 1600 1900 without GPU Reactor I get 1600 1900 but not stable yet..Will testing again later with GPU Reactor
March 30, 201213 yr Author sofos1990, i am not sure, because i have troubles with black screen under low temperatures.
March 30, 201213 yr still black screens?! .. had that issue on reference card. Really hated it, it's so unpredictable.. But nice benching. Im sure you'll hit 1700 soon
March 30, 201213 yr Author Yes, maybe it is depends from monitor or ports? Did you try hdmi or display ports?
March 30, 201213 yr slamms: what did you do to insulate on the back with the add-on card? It seems that could take some special consideration with all the frost that normally forms back there... Seems more complicated with that add-on card right where the frost mounds up typically.
