EVGA GTX 660 Superclocked 2GB reviewed - A closer look at GTX 660 SC

Review: 1920x1080 gamers' heaven

EVGA GTX 660 Superclocked (SC) uses dual slot cooling that looks much like the GTX 660 Ti’s cooler, well the GTX 670’s to be exact. You won’t see any difference between the coolers until you take the cooler apart. It’s a blower style cooler that is two slots wide.

One glance at the power and SLI connectors will in fact confirm that we’re looking at two different cards. The GTX 660 comes with one of each while the GTX 660 Ti has two of each.

The fan was is limited to 74% RPM in order to keep noise down. No need to invent hot water - the cooler handled the card quite well. The Base clock on the Superclocked card is higher than reference, i.e. up from 980MHz to 1046MHz, but this didn’t prove too troublesome for the cooler and it ran quiet even under load.

The PCB is 17.3cm long while the card is 24.3cm, which is clear once you look at the card from the back.

Power circuitry on GTX 660 Superclocked cards is towards the end of the PCB, exactly the opposite of how it was implemented on GTX 670 and GTX 660 Ti cards. This change required a redesign of the cooler as well.

The card has a metal heatsink that cools low profile components and holds the fan as well. GTX 670/660Ti cards have a plastic extension on the card, as you can see from the picture below. The new design improved stability.

The cooler uses a single heatpipe.

Almost all the cards we’ve tested so far used Hynix memory, but this time around it’s Samsung. The memory is model number K4G20325FD-FC03, meaning it’s GDDR5 specified to run at 1500MHz (6000MHz GDDR5 effectively). EVGA’s GTX 660 Superclocked packs a total of 2GB of GDDR5, in eight memory modules. Four of the modules are placed on the back.

The GTX 660 has a single SLI connector, which is usual for this price segment. So, it’s possible to boost performance and use two cards in SLI mode, but not more than that.

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.
