Zotac GeForce GTX 660 2GB Graphics card Review

[section_title title=P5 : Overclocking]

Overclocking :


So before we look at the benchmark results, lets see how this card overclocks. In all the benchmarks, the overclocked results have been included so you can see what kind of real world gains are seen. For overclocking, I used the EVGA Precision X utility. I set the power target to 110% (max allowed on this card) and started with overclocking.

The GTX 660 is not known for huge overclocks. The Zotac GTX 660 pretty much came with some modest overclocks. This is the most stable overclock I could achieve, which I tested with some 30 mins of gaming (Farcry 3).


So that’s an overclock of 115MHz (~11%) on the core and 95MHz (~6%) on the memory. The memory overclock was particularly disappointing.  Even a slightly higher clock would lead to instability. Lets see how this overclock reflects in real world gains.

Noise and Temperatures :

The card is very silent. Even in a silent room, you can barely hear it, but thats when it runs at around 30% speed. Running at 40%+, you can start hearing it and at 100% its pretty loud. During normal gaming though, you dont hear it at all.

Here are the temperatures at various load levels :
