EVGA GTX 660 Ti Superclocked (SC) graphics card has dual slot air cooling that is very similar to Nvidia’s reference design. The Base clock on the Superclocked card is higher than reference, i.e. up from 915MHz to 980MHz. Still, this didn’t prove too troublesome for the cooler which ran quiet even under load.
Although the GTX 670 is 24.3cm long, the PCB is only 17.3cm, which is clear once you look at the card from the back.
Nvidia moved the power circuitry from its usual spot at the end of the card towards the I/O panel. This left empty space at the end of the PCB, so the company simply cut it off and saved on materials.
GTX 660 Ti SC 2GB is powered via two 6-pin power connectors, just like the reference GTX 660 Ti or GTX 670 card. The reference GTX 660 Ti’s TDP is at 150W.
The blower style fan stands on the plastic bracket that’s mounted on the PCB.
The heatsink is made of one piece of aluminum. Since there are no heatpipes, the copper base was made pretty wide in order to boost dissipation.
EVGA’s GTX 660 TI SC packs a total of 2GB of GDDR5, in eight memory modules. Two of the modules are placed on the back.
You should know that EVGA plans for a version of the GTX 660 Ti with 3GB of memory in a few weeks time.
The memory chips in question come from Hynix (model No: H5GQ2H24AFR-R0C). They’re specified to run at 1500MHz (6000MHz GDDR5 effectively).
Video outs include two dual-link DVIs (only one is VGA capable) and standard HDMI and DisplayPort connectors. Note that all four outs can be used simultaneously.
The GTX 670 comes with two SLI connectors usually found only on Nvidia’s high end cards. This means that users can daisy chain more cards in a Quad GTX 660 Ti system. We're actualy not sure whether Quad SLI is possible, since Nvidia officially supports only 3-way SLI, however, we're talking about driver restrictions, so anything is possible. If you remember the 301.42 driver adds Quad SLI support for GTX 670.
