Symptômes

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/

OptiPlex 7020 (MT and SFF)	4	16 Gb	1600 MHz (DDR3/DDR3L Non-ECC)
OptiPlex 9030 All-In-One	2	16 Gb	1600 MHz
OptiPlex 7040 (Micro)	2	16 Gb	2133 MHz (DDR4 Synch DRAM))
OptiPlex 7040 (SFF, MT)	4	64 Gb	2133 MHz (DDR4)
OptiPlex 5040 (MT)	4	16 Gb	1600 MHz (DDR3L memory only)
OptiPlex 5040 (SFF)	4	32 Gb	1600 MHz (DDR3L)
OptiPlex 3040 SFF, MT, and Micro	2	16 Gb	1600 MHz (DDR3L memory only)
OptiPlex 7440 All-In-One	2	16 Gb	1600 MHz (DDR4 Non-ECC)

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.
