PC2-5300 is a type of DDR2 SDRAM, which is also known as DDR2-667. Its technical specifications are as follow:

Memory clock: 166 MHz

I/O bus clock: 333 MHz

Data transfers per second: 667 million

Peak transfer rate: 5333 MB/s

Cycle time: 6 ns

Memory timings: 4-4-4 or 5-5-5

Common chip capacity in PC2-5300 is either 1GB or 2GB. Combining two PC2-5300 chips, memory amounts of 3GB and 4GB are also frequently seen. 512MB chips are also available, however, they are not as common due to greater RAM usage in modern computer applications.

One side issue to consider is that technical limits do not allow the full 4GB to be used unless the operating system on the machine has 64-bit technology.

At times, the classification of PC2-5400 is used as a replacement term by certain manufacturers. In some cases, they claim above-standard transfer speeds, while others simply note that it is a rounded-up number.
