ASUS decided to equip the GeForce GTX 750 Ti Strix with a new version of their famous DirectCU II cooler. In case of this graphics card you get two heatpipes, both with six millimeter diameter. Soldered to the heatpipes is the fin stack which is being provided with fresh air via two fans. The fans on the new STRIX series are designed to spin only when GPU temprature reaches 65 degrees, which means that in 2D mode they are completeley off. Also, under low loads the fans do not start to spin. Under high-load the noise level is near silent, subjectively speaking.
The ASUS GTX 750 Ti Strix OC Edition graphics card, or to be precise our sample of
it, allowed a maximum stable overclock of 1'422 MHz
for the GPU and 1'650 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 1.21 Volts and the memory ran at stock voltages.
A closer look at the PCB shows that ASUS equipped this graphics card with
a 2+1
phase power design. The GPU gets its current from two phases and one
phase is taking care of the memory.
Checking the voltage regulation chip we find a uP1631P from uPI Semiconductor for the GPU an
EM5305 for PLL and an EM5106 controller chip for the memory.

The memory chips on the GTX 750 Ti Strix OC Edition come from Hynix and carry the model number H5GC4H24MFR. They are specified to run at 1'500 MHz (6'000 MHz effective).
