System-Specific DDR3 Module

This 4 GB stick is built for Dell OptiPlex 990 desktop and tower configurations. It carries the CMS CM5126410600DIMM part number and is tested for direct compatibility with DT, MT, SFF and Ultra chassis. The module installs in a standard 240-pin DDR3 slot without extra configuration.

Compatibility Focus

The part suits owners who need a single 4 GB upgrade for a supported OptiPlex 990. It will not work in systems that require ECC, registered memory, a different pin count, or a voltage other than 1.5 V. Buyers with other Dell models or non-DDR3 platforms should verify their motherboard specifications first.

Decisive Specification

The 240-pin DDR3 interface running at 1333 MHz (PC3-10600) with CL9 timing and 1.5 V unbuffered operation determines whether the module fits and functions. If the target system calls for a different speed, latency, voltage or form factor, this stick is not the correct match.

Perguntas sobre este artigo

Does the DDR3 1333 MHz rating cap the memory bus at PC3-10600 speeds on the Dell OptiPlex 990?

Yes, the module is rated DDR3 1333 (PC3 10600) and will run at that data rate on the OptiPlex 990 platform.

Will the 240-pin DIMM fit the DT, MT and SFF chassis of the OptiPlex 990?

The 240-pin DDR3 DIMM form factor matches the memory slots used across the OptiPlex 990 DT, MT and SFF models.

Do I need to configure anything in BIOS after installing this unbuffered non-ECC stick, or is it plug-and-play?

The module is unbuffered, non-ECC and runs at standard 1.5 V, so the OptiPlex 990 detects it automatically with no BIOS changes required.
