Overclocking the EAH3850 TOP
Although the EAH3850 TOP is already overclocked, we took some time to see how much more we could squeeze out of this card. Recall that the EAH3850 TOP's core comes clocked at 730 MHz while the memory runs at 950 MHz (1.9 GHz DDR), and a reference HD 3850 runs at 670 MHz and 830 MHz (1.66 GHz DDR), respectively. Using Overdrive and some trial and error, we were able to push the EAH3850 TOP to 775 MHz for the core and 1050 MHz (2.1 GHz DDR) for the memory. As usual, we have to state that your mileage may vary.
Our overclock didn't result in much of a performance gain in many of the tests, but the second chart below shows a nice gain of 4 FPS in Half-Life 2: Episode 2 at a resolution of 1600x1200 with AA and AF disabled.
