The
R530 core is at the heart of the Connect3D X1600 XT. Since clock speeds are
the major difference between the Pro and XT cards, overclocking should also
play a huge part in testing of the X1600XT.
The
lack of an applied heatsink on the memory modules is of no concern. It is
what it is. With all the time we've spent testing, and with other 3rd party
test results, the fact has been proven. A heatsink on memory modules will
not increase your overclocking potential.
With the ATI Tool, overclocking a video card has NEVER been
easier. It has a routine which will find the highest stable core and memory
speeds by itself, or you can do it the old fashioned way. I choose to
do a mix of both. Let it find what it thought was the maximum, and then I
took it from there.

The
maximum overclock does give us nice little increase over stock speeds. This
overclock is achieved with absolutely no negative effects to image quality;
ie: tears, artifacts, or snow.
