Technical data / Specifications
With the TGT GeForce GTX 660 Ti Ultra Charged Low Leakage Selection you get a factory overclocked card with a
reference PCB design
cooled by a dual fan cooler. Furthermore you get an hand picked GPU core which
has high ASIC quality. The ASIC quality of our sample is as good as the quality
of our
DirectCU II Top from ASUS.
About ASIC quality:
Looking at clock speeds we see that the GPU runs at 1'033 MHz with a
typical boost of 1'111 MHz. The stock designed GTX 660 Ti runs at 915 MHz with a
typical boost of 980 MHz. No factory overclocking has
been made regarding
the GDDR5 memory with stays clocked at 1'500 MHz (6'000 MHz effective) following nVidia's
recommendations. Too bad we would have loved to have.

As for the physical specifications, the Ultra Charged LLS' PCB is
according to the
reference design and has been manufactured by Point of View. There are
two
different versions of this graphics card, there is also one with the stock design cooler. The one we are reviewing here is the dual fan version.
I don't know if the whole cooler is manufactured by Colorful but I know that the
two 80mm sleeve bearing fans are. The model number of the fans is CF-12815S. The
heatsink has been well manufactured. The base as well as the two 6mm heatpipes
are made of nickel plated copper. The fins are made of aluminium.
TGT's graphics card also features a metal plate which is not present on
POV's card. This sort of a thermal shield which is there to spread the heat
in a more efficient way. The metal sheet covers the memory chips as well as the
power design area.
The memory chips used, have been made by Samsung and carry the model number
K4G20325FD-FC03. They are specified to run at 1500 MHz (6'000 MHz effective).
