HP Pavilion DDR2 upgrade

This 1 GB DDR2 533 module is built for HP Pavilion desktops such as the A1025C, A1030N, A1032C, A1034N, A1035C and A1040N. It installs in a single 240-pin DIMM slot and runs at 1.8 V with CL4 timing. The stick is unbuffered, non-ECC and uses a 2Rx8 rank configuration.

Owners of listed Pavilion models

Owners of the listed Pavilion models can add 1 GB of matched memory without guesswork. Systems that require ECC, registered modules, higher densities or a different DDR generation will not accept this stick.

240-pin DDR2 533 interface

The 240-pin DDR2 533 interface is the sole fit criterion; the module must match the motherboard slot and voltage exactly. If the board uses a different pin count, speed or voltage, the DIMM will not seat or function.

Questions about this item

How do I install the 240-pin DDR2 DIMM in my HP Pavilion a1030n, and what step is often missed?

Align the notch on the module with the key in the slot, press down firmly until both side clips snap shut automatically; the step often missed is verifying both clips have fully engaged before closing the case.

What maintenance or replacement will this 1 GB PC2-4200 module need later?

No routine maintenance is required; if a memory error appears, run a diagnostic such as MemTest86 and replace the stick only if errors persist.

What limit shows up first under sustained use with this CL4 1.8 V unbuffered memory?

The 533 MHz DDR2 bus bandwidth and CAS 4 latency become the bottleneck before thermal or voltage limits are reached.
