Overclocking: Dual- vs. Quad-Core CPUs

GEIL Memory - An Overclocking Natural

We equipped our test systems with 2 GB of memory, with our budget set at a maximum of $95. Memory maker GEIL offers some excellent products in this price range. We finally settled on the DDR2-800 modules of the Black Dragon Edition with the designation GB22 GB6400C4DC, which are sold as a 2 GB set (2 x 1 GB).

Don't take those two red LEDs the wrong way - they aren't meant as a warning; they're more of a fashion statement. In our test, we were able to overclock GEIL's modules to remarkable heights.

Although the label on the modules states an operating voltage of 2.0 Volts, we reduced the voltage to 1.95 V for our overclocking tests. Despite this reduction, our stress test tool Prime95 ran completely stably.

In our test, we were able to push the memory as high as DDR2-900 without having to change the latencies from their stock settings of CL 4.0-4-4-12 or raising the voltage above 1.95 V. Despite this high frequency, it still didn't get warm enough to require any cooling.
