4GB DDR2 Kit for Dell OptiPlex 745

This 4GB kit contains two 2GB DDR2 667 PC2-5300 DIMMs built for the Dell OptiPlex 745 desktop. Each module runs at 1.8V with CL5 5-5-5 timings and uses unbuffered, non-ECC 240-pin DDR2 SDRAM. The 2Rx8 rank configuration and major-brand chipset deliver reliable operation for this specific system.

Ideal for OptiPlex 745 upgrades.

Owners of a Dell OptiPlex 745, 745c or 745 ultra small form factor desktop can install these two sticks to reach 4GB across the board's two or four sockets. Machines that require ECC, registered modules, or a different DDR generation cannot use this kit, and boards limited to lower densities will not recognise the full capacity.

DDR2 667 PC2-5300 speed rating

The decisive specification is the DDR2 667 (PC2-5300) speed grade matched to the OptiPlex 745 memory controller. Installing modules rated for a different speed or voltage will prevent the system from posting, so this exact rating confirms the kit is the correct part for the target desktop.

商品問答

Does the Dell OptiPlex 745 need to support DDR2 667 unbuffered non-ECC memory for this kit to work?

Yes, the kit is DDR2 667 PC2-5300 unbuffered non-ECC; the OptiPlex 745 must accept that specification.

Can I keep existing DDR2 modules and add this 2x2GB kit to the remaining slots?

You can mix it with other DDR2 DIMMs, but all sticks will run at the speed and timings of the slowest module installed.

How can I confirm the kit is running at DDR2 667 with CL5 timings after installation?

Open Task Manager’s Performance tab or a tool like CPU-Z; the memory tab should show 667 MHz and 5-5-5 timings at 1.8 V.
