HIS Radeon X600XT Review
Posted on by LSDsmurf
To put it simply, this card is an overclocking monster. Pushing the core speed to 567MHz, we were also able to reach 452Mhz (x2) on the memory. I ran the card at these settings from more than four hours playing both Far Cry and UT2004 and no artifacts or lock ups. That is almost a 20 percent increase in memory speed and 13 percent in core speed, and the FPS showed it in the benchmarks.
