512 MB DDR PC2100 desktop module

This 512 MB desktop DIMM uses DDR memory rated at PC2100 (266) with a CAS latency of 2. It operates at 2.5 V and follows the 184-pin unbuffered standard. The module is suited for legacy systems that require this specific density and speed.

Thermals noise and power draw

The module runs at the standard 2.5 V for DDR PC2100 memory. As a passive component without active cooling, it produces no audible noise. Power consumption is determined by the memory controller and the 2.5 V supply rail during normal operation.

Build quality and connectors

The stick uses a 184-pin gold-finger edge connector that keys into a desktop DDR DIMM slot. It is organised as 2RX8 with 64M×64 density built from 32M×8 chips. The unbuffered design means it connects directly to the memory bus without a register.

Questions about this item

How do I install this 184-pin DDR DIMM and what step is often missed?

Align the notch on the module with the key in the 184-pin slot, press down firmly until both side clips snap shut, and verify the 2.5 V requirement matches your motherboard before powering on.

What maintenance or replacement will this 512 MB DDR module need over time?

No scheduled maintenance is required; if errors appear, test with a memory diagnostic and replace the module if it fails, as the chips are not serviceable.

What limit appears first when this CL2 266 MHz memory runs under sustained load?

The CAS latency of 2 cycles at 266 MHz sets the timing floor, so bandwidth and latency cannot improve beyond the rated PC2100 specification during extended use.
