Target system

This is a 2 GB kit of DDR2 400 memory built for Dell Dimension 4700 and 4700C desktops. The kit contains two 1 GB unbuffered DIMMs that run at 1.8 V with CL3 timing. Each module uses a 240-pin DDR2 interface and a 2Rx8 chip organisation.

Who it suits

It suits owners of the listed Dell models who need to add or replace memory and want a matched pair that is guaranteed compatible. Builders working on other platforms, or anyone who requires ECC, registered modules, or a different DDR generation, should look elsewhere.

Deciding specification

The memory operates at DDR2 400 (PC2 3200) with a CAS latency of CL3. If the target system requires this exact speed and timing combination the kit will work; if the board needs a different DDR2 speed, a different latency or a newer DDR generation the modules will not be compatible.

Perguntas sobre este artigo

Does the 240-pin DDR2 DIMM fit the Dell Dimension 4700 and 4700C motherboard slots?

Yes, the 240-pin DDR2 DIMMs are designed for the four memory sockets in the Dell Dimension 4700 and 4700C series.

What is the correct way to install the two 1 GB modules so the system recognises the full 2 GB kit?

Insert each module firmly into a slot until the retaining clips click; the common mistake is not pressing hard enough to seat both ends.

Will the non-ECC unbuffered 1.8 V modules need any firmware updates or voltage adjustments later?

No, the CL3 400 MHz modules run at standard 1.8 V without ECC or buffering, so no firmware or voltage changes are required.
