NVIDIA Titan X (Pascal) Review

As noted earlier, the NVIDIA Titan X graphics card features a reference design cooler. What you get is a radial fan (blower-type) pushing warm are over a dense heat sink out of a case. The heat is being removed from the GPU and carried to the fin stack thanks to a vapor chamber, which is basically a very wide heat pipe. Apart from the GPU, the memory chips, as well as all other critical parts, such as the power design has been integrated into the cooling loop as well. Checking the connector cables, we see that there are two of them, whereas the black 4-pin cable connects the fan and the one with the white 2-pin plug is there to provide power to the backlight GEFORCE GTX logo on top of the card. Flipping the card around there is a nice looking back plate, which has also been equipped with thermal padding to help dissipating heat from the power design more evenly.
The NVIDIA Titan X graphics card, or to be precise our sample of it, allowed a maximum stable overclock to 2050 MHz for the GPU and 1425.6 MHz on the memory side. With these clocks we had to feed the GPU with 1.062 Volts and the memory ran at stock voltages.
A closer look at the PCB shows that MSI equipped this card with a 7+2+1 phase digital power design. The GPU gets its current from seven phases, two phases take good care of the 12GB of GDDR5X memory and one additional phase is in charge of PLL.
The memory chips used are made by Micron and carry the model number 6LA77-D9TXS. They are specified to run at 1250 MHz (10000 MHz effective).
