2 GB DDR2 SODIMM for HP notebooks

This 2 GB DDR2 533 MHz SO-DIMM upgrades HP and Compaq Business Notebook NC8430, NX6310 and NX6320 models. It uses a 200-pin unbuffered non-ECC design with CL4 4-4-4 timing at 1.8 V. The single module contains sixteen memory chips in a 2Rx8 rank configuration.

Straightforward notebook installation

Power off the notebook, remove the battery and open the memory access panel. Insert the module at the correct angle until the retention clips snap into place. The only common issue is seating the stick fully; if the system does not recognise the memory, reseat it and verify the slot is clean.

Verify the exact model and slot availability

Confirm your notebook is one of the three listed models before ordering. Check that a 200-pin DDR2 SO-DIMM slot is free, as these systems do not accept other DDR generations or pin counts. The module is sold as a single stick, so total capacity depends on how many slots your chassis provides.

Questions about this item

How can I confirm the CM256644200SO module is running at the correct 533 MHz speed after installation?

Enter the system BIOS or use a utility such as CPU-Z; the memory tab should report DDR2-533 (PC2-4200) with 4-4-4 timings at 1.8 V.

What comes in the package and is anything else required to complete the upgrade?

The box contains one 2 GB 200-pin DDR2 SO-DIMM stick; no additional parts are needed if the notebook has a free slot.

Which capacity should I choose for an HP nc8430, nx6310 or nx6320?

This 2 GB module is the listed capacity for those models; add a second identical stick only if the specific notebook supports dual-channel and has a second slot.
