CNET editors' buying advice
We have not reviewed this product but here is CNET's buying advice on RAM (Random Access Memory). This content was chosen based on the features included with this model of ram (random access memory).
DDR2 RAM
DDR (Double Data Rate) 2 memory is the current standard type for home computers and laptops. Desktops use 240-pin DIMMs and laptops use 200-pin SO DIMMs. While the DIMMs are the same size and shape as DIMMs for other types of memory, the number of pins is different, and the "keying notch" is in a different position, preventing accidental installation in an incompatible system. DDR2 memory comes in a number of different speeds, and a system will run at the speed of the slowest DIMM installed. The general specifications of each type are as follows:
| Standard name | Module name | Memory clock | I/O bus clock | Peak transfer rate |
| DDR2-400 | PC2-3200 | 100 | 200 | 3200 MB/s |
| DDR2-533 | PC2-4200/4300 | 133 | 266 | 4266 MB/s |
| DDR2-667 | PC2-5300/5400 | 166 | 333 | 5333 MB/s |
| DDR2-800 | PC2-6400 | 200 | 400 | 6400 MB/s |
| DDR2-1066 | PC2-8500/8600 | 266 | 533 | 8533 MB/s |
Technically, the first column of the table lists the name used to describe individual RAM chips, and the second column is the name used to describe a complete DIMM. However, the two types of terminology are often used in confusing ways, and it best to keep both terms in mind when looking for a particular type. Additionally, some types have two different numbers that the DIMMs will appear under because of the manufacturers rounding the transfer rate numbers differently.
