Mushkin PC2-5300 DDR2 Memory
 

Quote: The maximum attainable speed we able to achieve with the PC2-5300 was a very respectable 321 MHz or a 642 DDR, slightly less than the 667 MHz Mushkin rates this memory to perform at. With the recent findings from the X-Bit Labs about DDR2 and low latencies it may turn out that DDR2 memory is not the black sheep of the family after all.
