System-specific DDR2 upgrade for Dell Latitude D830

This 4GB SODIMM module is built to the exact pin-out and timing the Latitude D830 expects. It installs in one of the notebook’s two memory sockets and runs at the platform’s native DDR2 800 speed. The stick is unbuffered, non-ECC and operates at the standard 1.8V for this generation.

Suits owners keeping a Latitude D830 running.

The module is validated only for the Dell Latitude D830 notebook. Systems that require a different pin count, voltage, DDR generation or ECC support will not accept it. Buyers who need more than 4GB per slot, a dual-channel kit or a newer memory standard should look at a different upgrade path.

Single stick with lifetime exchange warranty

The package contains one 4GB SODIMM rated at PC2-6400 CL6 with 2Rx8 organisation. Computer Memory Solutions backs the part with a limited lifetime warranty for exchange when purchased directly. No heat spreader, software utilities or additional accessories are included.

Questions about this item

Does the 200-pin DDR2 SO-DIMM slot directly into the Latitude D830 without an adapter?

Yes, the 200-pin DDR2 SO-DIMM form factor matches the Latitude D830 memory slots exactly, so it installs directly without any adapter.

Will this PC2-6400 800 MHz module run stably alongside an existing PC2-5300 667 MHz stick in the second slot?

The system will clock both modules to the slower 667 MHz speed, so the 800 MHz stick will operate reliably at the lower frequency alongside the older module.

How can I confirm the full 4 GB capacity is recognised after installing the CM512646400SO module?

Boot the notebook and check the installed memory in the BIOS or Windows System Information; it should report 4 GB (or 8 GB total if both slots are populated).
