System-specific DDR2 kit for Dell Optiplex 745

This 8 GB kit contains four 2 GB unbuffered DIMMs built to the DDR2 800 standard. It targets owners of Dell Optiplex 745 or 745C desktops who need to reach the platform's maximum memory capacity.

Four-module pack fills every slot at once

The kit supplies four matched sticks so all available sockets can be populated in a single upgrade. Each module runs at 1.8 V with CL6 6-6-6 timing and uses major-brand chips without heat spreaders.

DDR2 800 (PC2 6400) speed rating

The modules operate at 800 MHz with a PC2 6400 data rate. Buyers whose systems require a different DDR generation or a higher speed grade will not be able to use this kit.

أسئلة حول هذا المنتج

Will the four 2 GB DDR2 800 modules need any maintenance or replacement later?

The kit uses unbuffered non-ECC DDR2 DIMMs with no heat spreaders; under normal desktop use they are solid-state components with no moving parts, so no scheduled maintenance is required and replacement is only needed if a module fails.

What limit appears first when the memory runs at 800 MHz continuously?

Sustained operation at DDR2 800 (PC2 6400) with CL6 6-6-6 timings is constrained by the 1.8 V supply and the motherboard's memory controller thermal envelope, which typically reaches its thermal throttle point before any electrical limit.

How much noise, heat or power does the 8 GB kit produce when the system runs all day?

Four 240-pin DDR2 sticks at 1.8 V draw modest power and generate low heat; with no onboard fans or spreaders they add negligible acoustic noise, and total module power stays well within the Dell Optiplex 745 chassis cooling capacity.
