Dell Dimension 9100 memory kit

This Computer Memory Solutions kit provides 4 GB of DDR2 memory in a matched pair of 2 GB modules. It is built for the Dell Dimension 9100 series desktop and uses the 240-pin DIMM form factor. The modules run at 533 MHz with a CL4 timing of 4-4-4 at 1.8 V. They are unbuffered, non-ECC and use major-brand chips.

Owners of a Dimension 9100 needing a matched pair

The kit suits anyone upgrading a Dimension 9100 who wants a guaranteed-compatible pair of modules. It is not for systems that require ECC or registered memory, nor for platforms that use a different DDR generation or pin count. Buyers who need a larger single-module capacity should look at other options.

533 MHz DDR2 speed rating

The decisive specification is the DDR2 533 (PC2-4200) speed grade with CL4 latency. The Dimension 9100 chipset expects this exact data rate and timing; modules rated for other speeds may not train correctly. Confirm the 533 MHz rating matches the system documentation before purchase.

Questions about this item

Will the 240-pin DDR2 DIMMs fit the four memory sockets on a Dell Dimension 9100 desktop?

Yes, the kit contains two 240-pin DDR2 DIMMs designed for the four sockets in the Dimension 9100; the system supports up to 8GB total.

What is the correct way to seat the 2Rx8 modules so the system recognises both 2GB sticks?

Insert each module at a straight angle until the side clips click; the common mistake is stopping before the clips engage, which leaves the stick partly unseated.

Does the CL4 1.8 V kit require any future firmware updates or component replacements to stay compatible?

No firmware or replacement parts are needed; the memory is a passive DDR2 component with a limited lifetime warranty from the manufacturer.
