In Search of True DDR2 Bleeding Edge Memory

GeIL's DDR2-533 Fails To Impress

GeIL's modules registered the worst performance in our default test series - in particular on the Wstream test - for the entire test field. But things looked different in the overclocking test: this DDR2-533 module continued stable operation even at a speed of 952 (476 MHz). This leads us to suspect that the vendor may have shipped us hand-picked modules with especially good performance characteristics - something that would-be buyers can't necessarily expect when buying these units through normal retail. We'll test this hypothesis further in our upcoming THG DDR2 live test.
