The card is based on the ATI Radeon X600XT graphics processor, which allows it to bridge the gap between PC and home entertainment with a little thing we like to call 'HDTV.'

Overclocking the EAX600XT

As you'll soon see, at stock speeds the Asus eXtreme EAX600XT videocard does deliver decent frame rates. Of course, that's not good enough for us, so a little overclocking in due. ;-)

As usual, we began with the core at 500 MHz by default, and raised its speed a few MHz at a time. With good cooling on the Radeon VPU, we easily passed the 550 MHz mark, and blew past 560, 570 and 580 MHz as well. Continuing the adventure, passing 600 MHz core speed was also a breeze. The Asus EAX600XT seemed to hit a wall after passing 610 MHz; sometimes the card would run, sometimes it wouldn't.

As to what was holding it back I'm not sure of. The core was not artifacting, or giving us any problems before that point. Still, a 110 MHz core overclock is nothing to scoff at, and as you'll see it does boost performance nicely in the benchmarks to follow.

Asus equip the eXtreme EAX600XT with 2.2ns Hynix BGA DDR DRAM (370 MHz default speed), so we had high hopes in terms of overclocking the memory equally as well. Going up in 2-3 MHz intervals, we easily broke the 400 MHz plateau and everything was looking good. Unfortunately, the card ran into weird problems at 421 MHz, where the system would lock up when running 3DMark test. Heat from the memory DRAM on the rear of the card did not appear to be a problem...

ATi based videocards typically do not have problems running both core and memory at maximum overclocked speeds, and the Asus eXtreme EAX600XT was no different.
