MSI N275GTX

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!
