Galaxy GeForce GTX 275 OC 896MB Review

Manufacturer: Galaxy

A unique GTX 275 offering


The first GeForce GTX 275 graphics cards we saw came at the 11th hour in our testing of the new AMD Radeon HD 4890 card back in April; it is essentially one-half of a GeForce GTX 295 dual-GPU card with slightly increased clocks.  While that doesn't sound too exciting in does create a high performance single-GPU graphics card with a low price in comparison to the GTX 285 with the only real technical differences between the two cards being the memory bus width (448-bit vs 512-bit) and frame buffer size (896MB vs 1GB). 

Today we are looking at a new Galaxy model
that offers a custom cooler and overclocked specs to offer better than average performance, for a price.

The Galaxy GeForce GTX 275 OC

The cooler design on the Galaxy GTX 275 OC is pretty unique design with three large fans and a custom heatpipe cooler.

Clock speeds on the Galaxy GTX 275 OC run overclocked over reference specs:

  • 650 MHz core (vs. 633 MHz)
  • 1475 MHz shader (vs. 1404 MHz)
  • 1200 MHz memory (vs. 1134 MHz)

The GTX 275 GPU is a very powerful GPU as it actually matches the GTX 285 in most specifications including having 240 stream processors and very high clock speeds.  If you want to get all the technical details of this GPU and how it compares other offerings from NVIDIA and AMD, check out my combined initial review of the HD 4890 and GTX 275 from earlier this year.

You can see by looking at the back of the card that the cooler is actually longer than the card itself.

The GTX 275 reference card actually only required a pair of 6-pin power connections but this overclocked model from Galaxy requires a 6-pin and an 8-pin which should allow for some additional overclocking head room.

The GTX 275 supports adding in two more cards for 3-Way SLI if you power supply and system (and wallet) can handle it!

The external connectors on the card include a single dual-link DVI output, HDMI output and HDTV output with the included dongle.

The custom cooler on the Galaxy card uses copper heatpipes to move the heat off the GPU into the aluminum fins along either side of the card.  The memory chips are actually just cooled by a passive heatsink in this instance.


The extras included with the Galaxy card consist of a pair of PCIe power adapters, DVI-to-VGA adapter, component HDTV output dongle, S-Video cable, digital audio cable, drivers and installation instructions.
