The MSi N275GTX Twin Frozr OC is a DirectX-10 desktop graphics card based on the high-end Nvidia GeForce GTX 275. Like the N275GTX Lightning variation, the Twin Frozr OC makes significant adjustments to the base model's specs, boosting the core clock to 666 MHz and the memory clock to 2322 MHz. But the Twin Frozr OC features half the GDDR3 memory – 896 MB – of the Lightning, and lacks its built-in HDMI support – a DVI-to-HDMI adapter is optional. The GPU also lacks the Lightning's advanced cooling and overclocking, but still improves on the power design of the GTX 275, with two fans and five heatpipes enabling performance boosts via the included Afterburner utility. Unlike the higher-end model, the Twin Frozr OC supports TV output via optional S-video to composite connectivity.
