System-Specific DDR1 Upgrade

This 1GB DDR1 DIMM operates at 400MHz with CL3 timings and 2.6V voltage. It uses an unbuffered, non-ECC design with 2Rx8 organisation across 184 pins. The module is built with major-brand components and carries a lifetime warranty against manufacturing defects from Computer Memory Solutions.

Legacy Desktop Maintenance

Suited for technicians repairing or upgrading period-correct desktops that require DDR 400 (PC 3200) memory in a single 1GB stick. Not suited for systems needing ECC or registered modules, for builds requiring capacities beyond 1GB per slot, or for any platform that does not accept 184-pin DDR1 DIMMs.

Single-Stick Capacity Constraint

The decisive specification is the 1GB capacity on a single 184-pin unbuffered DIMM. If the target machine only supports smaller modules per slot or demands registered memory, this part will not function.

Questions about this item

Will the 184-pin DIMM fit my DDR1 motherboard slot?

Yes, this module uses the standard 184-pin DDR1 DIMM form factor designed for compatible desktop motherboard slots.

What voltage setting is required in BIOS when installing this 2.6V module?

Ensure the motherboard BIOS sets the memory voltage to 2.6V; incorrect voltage is a common cause of boot failure with DDR1 modules.

Does the 2Rx8 rank configuration affect future upgrades if I add another stick?

Mixing ranks can work but all memory will run at the slowest module's speed; matched pairs are recommended for best performance.
