Overclocking the quick Asus Videocard
The ASUS ENGTS250 DK videocard comes from the factory
with its nVidia G92 core clocked at 740 MHz and 512MB of GDDR3 memory running at
1100 MHz. PCSTATS has generally had great luck overclocking nVidia videocards, so our expectations where pretty
high for the Geforce GTS 250. As usual, overclocking was done through nVidia's
nTune utility which unlocks GPU and memory clock speed. PCSTATS started with the
GPU first, pausing to test the results with a quick 3D benchmark before
Starting with the GeForce GTS 250 core first, the clock
speed was increased in small 5 MHz increments, and in no time it hit 770MHz,
then 809... and artifacts. The ASUS ENGTS250 was pushed to 828MHz GPU, and while
it would complete the benchmark there were artifacts all over the screen. In the
end we had to dial back the overclock speed to a less exciting 809MHz GPU.
Still, that's 809MHz up from 740MHz, so I guess it's not too bad.
Next up was the 512MB of GDDR3 memory. Starting at 1100
MHz the memory was increased in 10 MHz steps. The RAM overclocked a little
easier, allowing us to push the ASUS ENGTS250 DK videocard's memory from 1100MHz
to 1145...1200...1240.. and finally 1320MHz - the limit for the memory slider in
Together the nVidia GTS250 GPU and GDDR3 memory ran
comfortably overclocked at 809MHz GPU / 1320MHz memory without crashing or any
obvious signs of artifacts in the 3D benchmarks.
With the baseline overclock of 809MHz GPU / 1320MHz
memory established, the second ASUS ENGTS250 DK videocard was dropped into the
MSI X48 Platinum motherboard and the system configured
to run in SLI mode. SLI systems tend to be limited by the slowest overclocking
videocard, and true enough we had a hard time getting the pair of ASUS GTS 250
videocards to run well at anything beyond 809MHz GPU / 1320MHz memory.
For the record, we were able to push the SLI'd ASUS
ENGTS250 DK videocards to 818MHz GPU / 1320MHz memory, but there were plenty of
artifacts so in the end we settled on the exact same overclocking result that
PCSTATS witnessed for the single ASUS GTS 250 videocard.
The details of how the Asus ENGTS250 DK HTDI/512MD3/AR/A
test system was configured for benchmarking; the specific hardware, software
drivers, operating system and benchmark versions are indicated below. In the
second column are the general specs for the reference platforms this nVidia
GeForce GTS 250 512MB based 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.
|PCSTATS Test System Configurations|
Benchmark results are organized 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.
