Capacity and fit

This 16 GB kit contains four 4 GB DDR2 registered ECC DIMMs built for the Dell PowerEdge R300. It targets administrators upgrading that specific server to its 48 GB maximum across six sockets.

Registered ECC benefit

Registered buffering reduces electrical load on the memory controller, allowing the platform to populate more slots reliably. ECC detects and corrects single-bit errors, protecting data integrity in continuous server workloads.

240-pin DDR2 module

Each stick uses the 240-pin DDR2 form factor keyed for 1.8 V operation at 667 MHz. The registered design and 2Rx4 organisation mean the modules install only in platforms that support registered ECC memory.

Questions about this item

Will the 240-pin DDR2 ECC registered modules need any firmware updates or periodic reseating during their service life?

No firmware is involved and reseating is not required under normal operation; the modules are designed for continuous server use.

What thermal or electrical limit is reached first when the 1.8 V registered DIMMs run at 667 MHz continuously?

The 1.8 V supply and registered buffering keep signal integrity within spec, so thermal limits are reached before electrical ones.

How much heat and power do the four 4 GB DDR2 sticks produce when the server runs all day?

Each module draws a modest 1.8 V current; combined heat output is low enough for standard server airflow without extra cooling.
