Compatible Dell OptiPlex upgrade
This 2GB DDR2 module is built for Dell OptiPlex 210L 320 330 740 745 755 desktops. It targets owners who need a single stick to fill an empty slot or replace a failed one. Systems requiring ECC or registered memory cannot use it.
DDR2 667 PC2-5300 ceiling
The DDR2 interface tops out at 667 MHz with CL5 timing and 1.8V operation. Bandwidth is limited to the PC2-5300 standard so heavier workloads will hit that ceiling quickly. A 64-bit operating system is required to address more than 4GB in total.
Simple DIMM installation
The 240-pin unbuffered DIMM drops into any free slot without tools. Modules may be installed one at a time but must be added in like pairs to enable dual-channel mode. If 4GB is installed the system may recognise only 3.5GB or less depending on configuration.

Preguntas sobre este artículo
Should I buy one 2 GB stick or add a second to reach 4 GB?
The Dell OptiPlex models listed accept 4 GB or 8 GB maximum. Install modules in matched pairs to enable dual-channel mode; a single 2 GB stick works but leaves bandwidth on the table.
What does the 667 MHz rating deliver inside an OptiPlex 755?
The module runs at PC2-5300 DDR2-667 with CL5 5-5-5 timing at 1.8 V, giving the rated throughput the platform’s chipset and memory controller can use.
Will this 240-pin DDR2 DIMM fit the OptiPlex 320’s memory slots?
Yes — it is a 240-pin unbuffered non-ECC DDR2 DIMM, the exact form factor and electrical spec those systems require.
