8GB Registered DDR Kit for Sun Blade

This 8GB kit from Computer Memory Solutions contains four 2GB registered DIMMs built for Sun Blade 1500, 2500, Sx1500 and Sx2500 servers. Each module uses a 184-pin DDR interface and includes ECC for data integrity. The kit is sold new and guaranteed compatible with the listed models.

Suitable for Sun Blade upgrades.

The modules match the Sun Blade 1500, 2500, Sx1500 and Sx2500 specifications, so they serve administrators restoring or expanding those systems. Builders working with any other workstation or server platform should look elsewhere because the pin layout, voltage and registration are specific to the listed Sun hardware.

184-pin DDR 266 registered ECC specification

The decisive specification is the 184-pin DDR 266 registered ECC design with 2.5V operation and CL2 timing. Only systems that accept this exact module type can use the kit, so verify the server documentation before ordering.

Questions about this item

Does the PC2100 rating limit bandwidth on a Sun Blade 2500?

The kit runs at DDR 266 (PC 2100), so the memory bus is capped at 266 MHz per module.

Will the 184-pin DIMMs fit the Sun Blade 1500 chassis?

Yes, each stick is a 184-pin DDR SDRAM DIMM, the form factor used by the Blade 1500 and 2500 series.

What is the correct order to install the four 2 GB registered DIMMs?

Populate the lowest-numbered sockets first; registered DIMMs must fill bank 0 before bank 1 to avoid a POST hang.
