Sun Blade Workstation Memory

This 4 GB DDR266 registered ECC module uses a 184-pin form factor and operates at 266 MHz. It is built for Sun Blade 1500, Blade 1500 Silver, Blade 2500 Silver workstations and the Netra 440 server.

Registered ECC Reliability

Registered signal processing and error-correcting code protect data integrity in continuous workloads. The dual 2 GB stick configuration fills two slots to reach the rated capacity.

Legacy DDR Upgrade Path

It replaces earlier DDR modules in the listed Sun systems when ECC and registered buffering are required. The jump is worth it only for those specific workstations and the Netra 440 server.

Questions about this item

Does the DDR266 standard cap the module at 266 MHz?

Yes, the DDR266 rating fixes the operating frequency at 266 MHz.

What slot and pin count does this 184-pin module require?

It fits a standard 184-pin DDR DIMM socket on the supported Sun workstations.

How do I install the two 2 GB sticks in a Blade 1500, and what step is often missed?

Populate the paired DIMM slots in matched banks and ensure both latches click fully; partial seating is the common error.
