The Asus EN7900GT TOP/2DHT/256M/A comes
factory overclocked to 520 MHz core and 1.44 GHz memory. This is up from 450 MHz
core/1.3 GHz memory on stock GeForce 7900GT videocards. That is already a pretty
healthy overclock on both the core and memory, but let's see how much further it
can go....
Starting with the core first, its speed was increased in
3-5 MHz intervals. The 'G71' core didn't play well with Coolbits and often
complained about the videocard being overclocked too high. After using my
personal voodoo, and chanting "core overclock be good!" several times, the
GeForce 7900GT core settled on a top speed of 561 MHz. Anything higher and
Coolbits simply wouldn't allow it. It's a shame because the 'G71' core felt like
it had more speed in it. Oh well, next up is the 256MB of GDDR3 memory.
Like the core, the Geforce 7900GT's GDDR3 memory is
already pretty heavily overclocked running at 1.44 GHz. Going up at in 6-10 MHz
intervals, the memory was able to crack the 1.5 GHz barrier but did not go much
past that. The top speed was 1.51 GHz. Considering a stock GeForce 7900GT's
memory runs at 1.3 GHz though, and that the Asus videocard is already running
1.44 GHz, that's not a bad memory overclock either.
The GeForce 7900GT core and 256MB of GDDR3 memory did
not have any issues running at their respective maximum speeds. At stock speeds
the Asus EN7900GT TOP/2DHT/256M/A is already a pretty fast videocard but when
overclocked blows the doors off everything else except the GeForce 7900GTX. As
you're just about to see, this makes quite a nice impact in the gaming
benchmarks.

experts tip: uninstalling drivers for
coolbits |
|
for some reason, when the coolbits registry hack
is entered in to the windows registry the nvidia overclocking plane still
does not appear. if this happens to you, instead of rummaging through the
registry the best thing to do is to uninstall the drivers completely then
reinstall. please note that reinstalling drivers on top of the installed
set often does not fix this issue, drivers need to be completely removed
from the computer first. after that's done, install the Coolbits registry
hack and overclocking will be available again. |
