Trying to find the "right" memory for one's PC is a difficult task, what with all the different brands and speeds to choose from for both Intel and AMD platforms. On the test block today is a 1GB set of dual channel DDR from Crucial. Sold under the Crucial Ballistix name, this pair of 512MB PC4000 DDR modules have been well received by the enthusiast community. The 184 pin (unbuffered, non ECC) DDR DIMMs are dual channel compatible and have a default rated speed of 250 MHz, or PC4000. Default timings are very conservative at 3-4-4-8. To reach an overclocked speed of 250 MHz, the memory is rated for use with voltages as high as 2.8V.
