Dell System Upgrade

This 512MB DDR2 533 module targets owners of compatible Dell systems needing a direct memory replacement. The 240-pin unbuffered design matches original specifications for straightforward installation. It addresses capacity limits in older workstations or desktops where larger modules are not supported.

Replaces Original Dell Parts

The module cross-references Dell part numbers A0375067, A0375070, A0498619 and A0498621 for exact compatibility. Upgrading is worthwhile when the system currently runs with less memory or exhibits slowdowns during typical multitasking. It restores intended performance without requiring BIOS changes.

Sustained Operation Stability

Unbuffered DDR2 533 (PC2 4200) timing delivers consistent data throughput during extended workloads. The non-ECC design suits standard desktop environments where error correction is not required. Thermal characteristics remain stable within the original system cooling envelope.

Questions about this item

Will the 240-pin DDR2 stick fit my Dell system that uses part numbers A0375067, A0375070, A0498619 or A0498621?

Yes. This 512 MB module is built to match those exact Dell part numbers, so it seats in the same 240-pin DDR2 slots.

What is the correct way to seat the module, and what step do people often miss?

Align the notch on the module with the key in the 240-pin slot, press down firmly until both side clips snap shut, then verify the system shows the full 512 MB at DDR2 533 speed.

When will this DDR2 memory need to be replaced?

DDR2 modules have no moving parts and require no scheduled replacement; they remain in service until a hardware fault appears or the platform is upgraded.
