1GB DDR400 Desktop DIMM

This 1GB unbuffered DIMM uses the DDR400 standard at PC3200U speed. It fits 184-pin desktop slots and is organised as 128Mx64 non-ECC memory. The module is new and intended for legacy desktop upgrades.

Who this suits

It suits owners of older desktops that require DDR400 184-pin memory for maintenance or modest capacity increases. It does not suit systems that need ECC error correction, registered modules, or capacities larger than 1GB per slot.

Capacity and headroom

The single 1GB rank handles basic office applications and light multitasking on period-correct platforms. It runs out when modern operating systems or memory-intensive workloads demand several gigabytes of addressable space.

Questions about this item

What type of motherboard slot is required for this 184-pin DIMM?

This module fits a standard DDR 184-pin DIMM socket on a desktop motherboard that supports DDR400 memory.

Can this non-ECC unbuffered stick run with registered ECC modules already installed?

No, mixing non-ECC unbuffered memory with registered ECC modules is not supported and will prevent the system from booting.

How can I confirm the module is running at DDR400 after installation?

Enter the BIOS or use a system information tool and verify the memory frequency reads 400 MHz (PC3200).
