Gigabyte GTX 660 Overclock 2GB Graphics Card Review

Taking a quick glance at the front of the card, its looks very similar to the 660Ti that we looked at not too long ago, and in many ways it is very much the same with twin 100mm fans and heastink cover to go alongside, overall offering 3.5% better cooling performance over NVIDIA’s reference cooler design.

Turning to the side, we can see that this cooler is a whole lot more than what we found on the Ti, with it extending nearly 2″ off the end of the PCB. Poking out the base we can see the ends of the four heatpipes that run from the GPU core transferring heat away to the heasink for dissipation.

As we saw in the introduction, the card as a lower power factor of ~140W and consequently we find a single 6-pin power connector nestled at the top of the PCB.

Even on the entry level scale, there is always the scope for gaining performance by scaling multiple cards into a system and so we find a single SLI connector on the PCB.

On the back of the card, we find a standardised set of out put connectors, with two DVI, a single HDMI and a full sized DisplyPort.

As mentioned, the GTX 660 comes with a reference core clock of 980MHz, boosting to 1033MHz with 2GB of GDDR5 memory running at 1500MHz. With this being a overclocked model, we can see that Gigabyte have raised the core clock to the former boost speed of 1033MHz with a new boost speed of 1098MHz and also the slightest of overclocks on the memory bringing it up to 1502MHz (6008MHz effective).
