Palit GeForce GTX 660 Ti Jetstream 2GB Review

Software and Overclocking

The included ThunderMaster OC utility is similar in layout and functionality to MSI's Afterburner and EVGA's Precision X, offering clock/voltage monitoring and adjustments and the ability to load/save profiles. The utility interfaces with the Nvidia driver API which does not allow voltage adjustments (the Core Voltage setting in the illustration below only locks the 3D voltage at 1.175v, which hinders any meaningful overclocking). Power limit on this board is restricted to 128%, which translates to 192W (base is 150W).

  Reference GTX 660Ti Palit GTX 660 Ti Jetstream Palit GTX 660 Ti Jetstream with OC
Core Clock 915 MHz 1006 MHz (+10%) 1076MHz (+7%)
Boost Clock 980 MHz 1085 MHz  (+11%) 1155 MHz  (+6.5%)
Memory Clock 1502 MHz 1527MHz (+2%) 1827 MHz (+20%)

As with any overclocking, your mileage will vary.


Temperature Testing

The point of this test is to determine the dexterity of the cooling solution (leaving the fan speed at AUTO will just mean the fans will ramp it when temperatures hit 70, which doesn't provide a controlled environment for science)

On the highly demanding Furmark 1.9 burn-in test, 100% fan speed (makes a huge ruckus but pushing a lot of air) kept the card cool at 50 degrees celcius. Typical temperatures in games should be around 40-50 degrees, which is an excellent result.



When overclocked and with the power limit raised, temperatures rise to 58 degrees, which is still way under the throttling threshold.
