EVGA Employee, a talented engineer and overclocker in one person, Ilya Tsemenko (TiN) recently shared his achievements in the overclocking of GeForce GTX 690 EVGA production under liquid nitrogen.
For obvious reasons, the author of experiment did not experience a lack of experimental graphics cards EVGA.
At each of the two GPUs installed a glass of liquid nitrogen with a copper base KingpinCooling production. Increasing the core voltage to 1.385 V at a temperature of from 40 to 50 degrees Celsius below zero allowed to keep the frequency of GPU at 1450-1500 MHz in the test 3DMark'11 Performance.
There was no significant modification to the power system supply, the core voltage was increased to 1.45 V. At minus 70 degrees Celsius GPU frequency has reached 1600 MHz, but the stable operation in this mode was not achieved.
A single card was eventually overclocked to 1547 MHz on the core, in conjunction with working at a frequency of 4.5 GHz processor, Core i7-3960X provided result in a score of P20962 3DMark'11. The combination of two GeForce GTX 690 was overclocked to 1458 MHz on the core, at a frequency of 4.9 GHz processor has been achieved the result P28812 3DMark'11. Related Products :
