MSI N465GTX Twin Frozr II
Overclocking using the MSI is simplicity itself thanks to the excellent Afterburner program. As always at OC3D we locked the fan speed to 50%. The stock speeds of the N465GTX are as seen below, 607MHz on the core, 1215 MHz on the Shaders and 3206 MHz Memory speed.
If MSIs 15% overclock is to be believed then we should see 698 MHz on the core and 1397 MHz on the Shaders. Given that memory never overclocks well on graphics cards we certainly don't expect any great gains there. What is basically 700/1400 seems rather ambitious, but let's see how close we got.
Strictly speaking, we didn't get close to that, we absolutely SMASHED it. Considering the reference cooler was so poor we couldn't overclock the stock card at all we weren't expecting much overhead. Giving a little leeway to the manufacturer to make lofty claims we hoped for about 650/1300.
So when we topped out at 826/1652, a staggering 36% increase, we were left nearly speechless. Just as impressive is the extra 80 MHz on the memory.
With a good voltage tweak we wouldn't be at all surprised if 850/1700 was possible. This is an absolute BEAST.
Of course all this extra performance is just potential if the Twin Frozr II can't keep those temperatures tamed.
MSI claim 16°C cooler than the reference design. Our testing, and before anyone leaps in with the "open bench rig" thing these are in a CoolerMaster case so it's exactly as you'll find them, we got 22°C cooler at idle and 25°C cooler at load using stock speeds. Once again MSI are seriously selling themselves short, which is a good thing compared to how often we've come across lofty manufacturer claims that are totally unsubstantiated in testing.
If that isn't impressive enough with our immense 36% overclock we were still 21°C and 20°C cooler at idle and load respectively.
220 MHz increase in core speed and still not breaking past 72°C after 30 minutes of Furmark anybody?
