Review: An overclocked card with two bundled games

Nvidia Geforce GTX 275 is a very interesting graphics card positioned somewhere between GTX 260 and GTX 285. It packs all 240 shader processors just like the GTX 285 but it comes with 896MB of memory like the GTX 260. Thanks to GT200’s high operating speeds and the fact that it has been built in 55nm, the GTX 275 is considerably faster than the GTX 260. This card will compete with Radeon HD 4890 1GB and while it beats it performance-wise, it is a bit pricier. If you’re looking for a gaming card at an affordable price, then stay with us and see what Inno3D has in store for you.

Inno3D GTX 275 Overclock graphics card has been pre-overclocked and runs at 700MHz core, compared to the reference design speed of 633MHz. Of course, higher clocks mean higher pricing but Inno3D made sure to compensate for that with two games – Company of Heroes (Opposing Fronts) and Warmonger (Operation: Downtown Destruction). Shaders have been overclocked from reference 1404MHz to 1500MHz and the memory got a boost from reference 1134MHz to 1210MHz.


The GTX 275 Overclock follows the P897 design and comes with reference cooling which is inaudible when in 2D and while it gets louder in 3D it’s still not too loud. The following photo shows Inno3D GF-GTX275-DUAL-DVI-HDTV-HDMI-GDDR3-896MB N276-1DDD-H3IYX PCI-Express card.

The card is dual slot and a good thing about the cooling is that it pushes hot air outside of the case. The fan is at the end of the card and it proudly bears the name Inno3D Overclock.


The GTX 275’s core packs serious potential, and Inno3D harnessed it well and pushed the clocks way above the GTX 285’s. Additional overclocking is of course possible, but we’d advise against it due to the warranty. Core temperatures have risen significantly during our testing and some intensive gaming pushed it to 90°C whereas idle mode resulted in only 38°C.

When the graphics card is idle, the card downclocks to 300MHz core, 601MHz shader s and 100MHz for the memory. Such operation mode enables power saving – our test system consumed less than 100W in idle and up to 376W during gaming. Thanks to the GT200 55nm chip on the GTX 275, consumption stays in acceptable limits, even lower than on the GTX 280. Maximum idle TDP goes up to 219W as the card has two 6-pin power connectors.

Power connectors are located on the usual spot towards the end of the card next to the white audio-in connector, which you’ll use to bring sound to the card via the provided SPDIF audio cable. Such a move will enable routing both audio and video to your HDTV via a single cable, otherwise you’d be stuck with video only.


The opposite side of the card features two dual-link DVI connectors with support for monitors with resolutions up to 2560x1600. The connectors are gold plated and if you happen to need a DVI-to-VGA or HDMI adapters, Inno3D included them in the box. The company also opted to use HDTV out on their card, which is something not found on the reference design.


In case you’re craving serious juice, Inno3D GTX 275 Overclock can be chained with another two GTX 275 cards and the SLI connectors are placed on their standard locations.


The graphics card’s PCB is green and all the Hynix H5RS5223CFR-N2C memory modules are located on the front side of the card, around the GPU. The card we tested has 896MB of GDDR3 memory, but if that doesn’t strike your chord Inno3D offers the GTX 275 with 1792MB of GDDR3 as well.

Apart from the two gift games, the packaging contains:


- The Graphics card
- Documentation + driver CD
- DVI Adapter + HDMI Adapter
- PCI-Express power cable
- TV out cables
- SPDIF cable
- Company of Heroes + Warmonger
- Nvidia’s 20% off voucher for Mirror's Edge
