Technical data / Specifications


With the MSI GeForce GTX 680 Twin Frozr III OC you get a factory overclocked card with a reference PCB design cooled by a dual fan cooler. The ASIC quality measured on our sample was 79.5 %. It's higher than the average you can get but nothing really special.
About ASIC quality:



Looking at clock speeds we see that the GPU runs at 1'059 MHz with a typical boost of 1'124 MHz. In comparison, the stock designed GTX 680 runs at 1'006 MHz with a typical boost of 1'058 MHz. Like most of the GTX 680 out there no factory overclocking has been made regarding the GDDR5 memory which stays clocked at 1'500 MHz (6'000 MHz effective) following nVidia's recommendations.

As for the physical specifications, the Twin Forzr OC's PCB follows the reference design. MSI didn't bother adding the full number of power components like EVGA did on the SuperClocked Signature 2 for exemple. Therefore you get four phases for the GPU and two for the memory.


MSI's graphics card also features a metal plate. The metal sheet covers the memory chips as well as the power design area to spread the heat in a more efficient way.



The cooler that keeps this card at adequate temperatures is the so called "Twin Frozr" rev.3. The cooler consits of a nickel-plated copper base and heatpipes with a metal shield and two 80 millimeter fans. It features two 8mm heatpipes plus three 6mm ones, all made of nickel-plated copper. The rest of the heatsink is made of aluminium. I have to say that I have seen way better looking base, this one is not polished at all.



The memory chips used are made by Hynix and carry the model number H5GQ2H24MFR-R0C. They are specified to run at 1'500 MHz (6'000 MHz effective).
