Overclocking
To discover our PNY GeForce GTX 780Ti XLR8 sample’s overclocking abilities we used EVGA’s Precision X software and began raising power and thermal thresholds to the maximum allowed and then increased the voltage the maximum permitted. Then using Unigine’s Valley benchmark we began stability testing and overclocked until instability occurred. A stable overclock was not considered stable until it passed an hour long torture test using Unigine’s Valley benchmark.
After hours of testing and tweaking we were able to boost performance to a peak of 1152Mhz –a whopping 24.1% percent over the cards default boost levels of 928Mhz. The memory was also able to run at an effective 7760Mhz, which is a very decent 10.8 percent improvement over the card’s default of 7000Mhz. Needless to say we are actually impressed with the PNY GeForce GTX 780Ti XLR8’s stock cooler. Such an increase is impressive given the more conservative and value orientated nature of this particular card.
As you can see the end result was a performance boost of easily over 10% in average frames per second with multiple frames per second improvement to the all-important minimum frame rate performance results. While you will still have to turn performance down to get to a minimum playable 30 frames per second in all games, a moderately overclocked 780Ti comes awfully darn close to not needing it in BioShock and a lot closer than expected in Crysis 3! Overall, these results just reinforce our opinion that the PNY GeForce GTX 780Ti XLR8 may indeed be expensive, but it does provide surprising value for the money.
