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 SLN152123_en_US__1iC_External_Link_BD_v1

2. Model Compatibility Matrix

NOTE: Best practice is to install memory in pairs of matched memory Size, Speed, and Technology. If the memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance.

 

NOTE: DDR3 and DDR3L

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/

NOTE: Voltage

DDR4 improved power efficiency over DDR3 and DDR3L memory technologies. Reducing DDR3L DRAM I/O voltage from 1.35 V used to 1.2 V.
