The card
As noted earlier, the GTX 980 Ti Gaming 6G graphics card features MSI's famous Twin Frozr V cooler with a total of four heatpipes, where three measure 8mm and one comes with a diameter of 6mm. Apart from that, there are two 100mm fans which cool the large heatsink connected to the nickel-plated copper base plate. As a part of the MSI Gaming series, the this particular cooler comes with a red on black color scheme and the overall build quality of the cooler is just great.
The MSI GTX 980 Ti Gaming 6G graphics card, or to be precise our sample of
it, allowed a maximum stable overclock of 1'480 MHz
for the GPU and 1'800 MHz on the memory side. We used Furemark V1.11.0 Geeks3D
benchmark with 15 minutes duration. With these clocks we had to feed the GPU
with 1.193 Volts and the memory ran at stock voltages.
A closer look at the PCB shows that MSI equipped this card with a
8+2+1 phase digital power design. The GPU gets its current from eight phases, two phases take good care of the 6GB of GDDR5 memory and two additional phase are in charge of PLL. Once more, MSI is using high quality chokes.
Checking the voltage regulation chip, we find a digital multi-phase buck
controller NCP8114.
The memory chips used are made by SKHynix and carry the model number
H5GQ4H24MFR. They are specified to run at 1'750 MHz (7'000 MHz
effective).
