Targeted Dell Optiplex 390 upgrade

This 4GB DDR3 module is built for the Dell Optiplex 390 desktop. It installs as a single 240-pin DIMM running at 1333 MHz with a CL9 latency. The stick operates at the standard 1.5 V and uses unbuffered, non-ECC chips.

Suits owners of the named system.

Buyers repairing or expanding a Dell Optiplex 390 will find guaranteed compatibility. The part is not ECC registered, so it will not meet the needs of servers or workstations that require error-correcting memory. It also does not fit laptops or systems that use a different pin count or voltage.

Single decisive specification: DDR3 1333 MHz

The memory must be a 240-pin DDR3 DIMM rated for PC3-10600 at 1333 MHz. If the target computer demands a different speed, pin layout or voltage, this module will not seat or function. Match this exact specification before ordering.
