Testing the MSI N275GTX Twin Frozer will consist of running the card through the Overclockersclub.com suite of games and synthetic benchmarks and comparing it against many popular competitors to gauge its performance. The games used are some of today's popular titles to give you an idea on how the cards perform relative to each other. The system specifications will remain the same throughout the testing. No adjustment will be made to the respective control panels during the testing with the exception of the 3DMark Vantage testing where Physx will be disabled in the nVidia control panel. I will test the N275GTX Twin Frozer at both stock speeds and then overclocked to see how much additional performance is available when you choose to overclock the card. Comparisons will be made against the performance of its contemporaries on both sides of the fence.

With the N275GTX having a little bit of a factory overclock the expectation was that the Twin Frozer cooling system would help reach an overclock that was a bit higher than the other cards I have looked at. I was not disappointed. I started out by increasing the fan speed to 100 percent using Riva Tuner 2.24 to allow the cooler to remove as much of the thermal load generated by the GPU and memory as possible. We all know that cooler running parts will in most cases deliver higher clock speeds. To bump up the clock speeds I used a tool called GPUtool. I started out with the clock speeds delivered by the ASUS ENGTX275 I recently looked at and the N275GTX passed through some preliminary testing without a hitch. Unfortunately the GPU clock and memory clock did not really move much higher and maxed out at 742MHz on the core and an even 1300MHz on the memory. Nothing to be ashamed of there on air. Now where the Twin Frozer took off was on the shader clock speeds. Just over 1500MHz was the barrier on the last 3 GTX 275's we have looked at so I was not expecting to pull 1600MHz out of this card but it kept scaling up to this level. All said and done 742/1600/1300 were the clock speeds reached for day to day operation. This level provided performance increases across the board in each benchmark and resolution tested. The final test was doing some Folding @ Home testing on the card to see if it could run at this level 24/7. This it did!
The only thing is that the noise with the fans at 100% are quite loud, but the cooling performance trade off for the noise level is worth it as long as you wear your headphones. The flip side to this is that with a slightly lower overclock and the fan speed run below the 75% mark the temperatures do not get out of hand. With the maximum overclock and 100% fan speed the N275GTX idled at 31 Celsius and loaded at 51 Celsius after looping 3dmark06 game test 3 for an hour. With the fan speed controlled by the drivers running at the stock clock speeds the card idled at 31 Celsius and loaded at 54 Celsius. Pretty decent numbers when all things are considered. The N275GTX Twin Frozer is at this time the highest overclocking GTX 275 that OCC has tested.
