The card
As noted earlier, the MSI Twin Frozr Gaming GTX 780 OC Edition graphics card
features MSI's quite famous Twin Frozr IV cooler with a total of five heatpipes,
three 6mm and two 8mm ones. It has two 100mm fans which cool the large heatsink
connected to the nickel-plated copper base plate via aforementioned heatpipes.
As a part of the MSI Gaming series, the Twin Frozr Gaming GTX 780 OC Edition
uses red on black color scheme and the overall build quality of the cooler is
quite good.
Like most of MSI' recent high-end cards the PCB has been completely reworked
and the power design beefed-up. The custom PCB features 6+2-phase design (there
are five on the reference card) with six phases for the GPU and two
phases for memory. It is an analog power design with NCP4206 voltage regulation
chip for the GPU, APL7142 PLL voltage regulator chip, APL3516A memory voltage regulator chip
and SiC780 MOSFETs.
The memory chips used are made by Hynix and carry the model number
H5GQ2H24AFR. They are specified to run at 1'502 MHz (6'008 MHz effective).
