Да ну, как так? в кросе на 625W? Бред какой то!

О как...т.е. ближе к 90 уже близимся

Интересно, при повышении напряжения на сколько температура возрастет?

Wow! 1.337V on the GPUs resulted in 980 MHz Core, 1300 MHz Memory.
All that with the stock cooler, fan speed let at default (yes it gets noisy).

Не справитс она с охлаждением, а при повышении напряжения тем более

1.337V

The overclocks of our card are 780 MHz core (8% overclock) and 1310 MHz Memory (31% overclock). These clocks reflect about what I expected. Memory overclocks very well because the chips are specified to run at 1250 MHz at least. The core however seems to be held back by heat and voltage.

Temperatures look ok. Even though the idle temperature looks a bit high, I find it an acceptable tradeoff for the reduced idle fan noise. Under load the card stays within safe temperatures, unlike other dual GPU cards which can easily go far beyond 100°C.
The overclocked temperatures are only marginally higher because as temperature increases, so increases the fan speed which helps with keeping the temps in check.

Please note that "OC" here refers to the first overclock (780/1310). When I tested the voltage increase + overclock I had already disassembled the card and replaced the thermal paste when reassembling. Temps of voltage increase + oc were around 95°C in that case.
