Biostar's
V903GT52-NV1AN videocard runs at the default clock speeds, so we should be able
to overclock it by a healthy amount. For the record, the V903GT52-NV1AN's Geforce 9600GT core is clocked at
650 MHz, memory at 1800 MHz. Starting with the GeForce 9600GT GPU first, PCSTATS will
be increasing the clock speed in 25 MHz increments.
Overclocking the
Biostar V903GT52-NV1AN was accomplished with nVidia's nTune
software, and in a matter of minutes the GPU was humming at 765MHz. That
was the maximum OC speed for the Palit
Geforce 9600GT PCSTATS recently tested.
Anyway, the core clock speed was increased to 775MHz, and then 789MHz
and finally 791MHz. Once we went past 775MHz artifacts started showing up,
so that is the speed we ended up sticking with. Out of curiosity, we did try
overclocking the Biostar V903GT52-NV1AN GPU all the way to 814MHz, but it failed
the nTune internal test and crashed the system.
Next we set about
overclocking the 512MB of GDDR3 memory. Beginning at 1800 MHz, the memory was increased in 40 MHz
increments.
The memory cooperated well, so we overclocked in leaps and bounds until
the slider in nTune maxed out at 1100MHz, which left us with a maximum overclock of
2200MHz.
For mainstream
GPU like nVidia's Geforce 9600GT, the Biostar V903GT52-NV1AN videocard overclocks well - especially nice because it's not
sold with the price premium of a pre-overclocked model.
Prelude to
Benchmarks:
The details of
how the Biostar V903GT52-NV1AN test system was configured for benchmarking; the specific hardware, software
drivers, operating system and benchmark versions are indicated below. All benchmarks for
the Biostar V903GT52-NV1AN were run in Windows Vista Ultimate, the reference videocards
were tested in both Windows XP and Vista for the DX10 benchmarks.
PCSTATS is in the process of making the transition
to a Windows Vista only test platform, so keep this in mind as you scan the
benchmark results. In the second column are the general specs for the reference
platforms this nVIDIA GeForce 9600GT videocard is to be compared against. Please
take a moment to look over PCSTATS test system configurations before moving on
to the individual benchmark results on the next page.

Benchmarked results are grouped by GPU manufacturer
first (AMD/ATI or nVidia), then by GPU generation, and then by GPU
class (high end, mainstream, value). This approach provides a clearer view of how performance
can differ from generation to generation, and class
to previous generation. The product being tested is marked with the red
colour bar.
