Just because we go out and buy a reasonably expensive video card doesn't mean we don't want to tweak it, does it? Of course not!
Default speeds of the X850XT board is 540MHz core and 590MHz memory; effectively 1190MHz with the DDR factor figure in. Since this isn't all the board can do I decided to put it through its paces a bit to see how far we could go. Though I was able to crank the core up over 600MHz, I ended up with artifacts, so I backed it off to 586MHz. At this core setting I was able to easily complete all benchmarking tests and none showed any sign of glitches.
The memory, on the other hand, didn't do nearly as well. It is speed rated at 600MHz and that was the limit I could maintain without artifacts. It would operate at around 610MHz before crashing the system but the display was not free from errors.
To show some of the more recent tests, I'll include a few charts that give you the results from default to overclocked performance.
All tests run showed a marked improvement, and we all know that faster is better!
How much does it cost?
