Among the numerous DDR memory modules with 1GB capacity available today on the market, modules on Infineon's revision C chips seem to be the best. Such modules can work with 2-3-2 timings at frequencies near 200MHz (400MHz DDR), with 3-3-2 timings at 250MHz (500MHz DDR) frequency, and with "bad" timings at 280MHz (560MHz DDR) and higher.

Among the products we have reviewed today, the pair of OCZ PC4000 EB Dual Channel Platinum Edition modules features such chips. And it is this memory kit that has shown the best overclockability and maximum performance in our tests.

We'd want to draw your attention to the Corsair TWINX2048-3500LLPRO kit, too. Although the overclocking potential of these modules is lower than of the OCZ PC4000 EB Dual Channel Platinum Edition, they boast better stability with the aggressive 2-3-2 timings at frequencies over 220MHz (440MHz DDR). Moreover, these modules look cute and have a LED indicator on the top edge. On the other hand, don't forget about the possible problems that may arise due to their really huge size.
