Once upon a time, while digging in his piles of old and very old computer
hardware, the author has spotted a Sapphire Radeon 9600XT 128Mb AGP video card.
Well, there is nothing really special about it, just a fast mainstream hardware
of not so far past. It hasn't accommodated even a Rage Theater chip for video
input capabilities. Furthemore, eight Samsung K4D261638F 128Mbit 3.3ns GDDR SDRAM
memory chips (
PDF datasheet, 168Kb) of TSOP-II
packaging haven't seemed to be as promising as BGA packaged ones which can be
found on many other Radeon 9600XT cards. Finally, the cooling hasn't looked
attractive either.

Hell knows why the author has decided to try this card for overclocking, but
the results have appeared to be quite interesting. RV360, the graphprocessor,
has been able to reach 553.50MHz from default 499.50MHz without any sign of
overheating. The memory has been pushed even better — from default
297.00MHz (594.00MHz effective) to 371.25MHz (742.50MHz effective). Things
become even more interesting if to take a look at the datasheet and to find out
that the fastest memory of this type is labelled to run at 350MHz (700MHz
effective) with increased from 2.5V to 2.8V power supply. So, this card has
shown to be worth of further actions. That's right, it's time for advanced
overclocking!
