Overclocking the GXT 650 Ti Boost followed the natural progression
of most other Kepler-based cards. This involves increasing the Boost Offset, Memory Offset and Power Target within EVGA's Precision software. For those wondering, the maximum Power Target on this card is currently 110%, though certain "unlocked" software will likely push it beyond that.
In order to dial in the clock speeds, we used a combination of Precision and EVGA's OC Scanner. However the actual core voltage wasn't touched, even though Precision allows for up to 1.15V, up from the reference 962mV while the fan speed was set to a constant 50%.
With the settings detailed above, the Boost achieved decent clock speeds of 1205MHz and 6544MHz on the core and memory respectively. The core value actually represents the AVERAGE core frequency in-game, measured across our entire testing suite. We actually saw it climb to 1265MHz at some points but they were few and far between.
Naturally, the increased clock speeds all but guarantee the GTX 650 Ti Boost will nearly catch up to a stock GTX 660 2GB.
