1. Memory Speeds
Some confusion has been created due to the difference in the listings for speed ("MHz"), and the way memory is described from a sales standpoint ("personal computer XXXXXX"). The listings below should resolve any confusion.
| PC3-6400 | 800 MHz |
| PC3-8500 | 1066 MHz |
| PC3-10666 | 1333 MHz |
| PC3-12800 | 1600 MHz |
| PC3-14900 | 1866 MHz |
| PC3-17000 | 2133 MHz |
Only showing 4 GB?
To fully use 4 GB or more of memory, require a 64-bit enabled processor and 64-bit operating system. With 32-bit operating system, the total amount of available memory will be less than 4 GB. The amount less depends on the computer configuration. See the following Microsoft article: Memory Limits for Windows Releases 
2. Model Compatibility Matrix
Below memory compatibility will be DDR3 unless stated otherwise. (example: DDR3L)
DDR3 is not backward-compatible with DDR2.
DDR3 and DDR3L are socket compatible, however, It is NOT compatible with computers using 4th Generation Intel (Haswell) processors, which exclusively support 1.35 V operation for memory.
Example:
System will shut down early in POST with a specific error code or beep code. Technical Support must verify that the right memory is used on these computers to prevent unnecessary dispatches.
For older legacy computers not listed below, check your computer manual for more information about hardware compatibility. https://www.dell.com/support/manuals/
