Dell Precision T5500 ECC RDIMM

This 8GB DDR3 module is built for the Dell Precision T5500 workstation. It delivers registered ECC memory for environments that require error correction and signal buffering. The single stick installs directly into a 240-pin DDR3 slot.

Registered ECC changes compatibility

Registered buffering and ECC make this module incompatible with standard desktop boards and with unbuffered memory. It is designed for workstation, server, NAS and router platforms that specifically support registered DIMMs. Mixing it with unbuffered sticks will prevent the system from posting.

DDR3 1333 CL9 1.5V 2Rx4

The module runs at 1333 MT/s with CAS latency 9 at 1.5 volts in a dual-rank 2Rx4 organisation. That speed, voltage and rank combination is the deciding factor for the Precision T5500 memory controller. Systems needing a different speed, voltage or rank layout cannot use this part.

Questions about this item

Will the 240-pin DDR3 RDIMM need any firmware updates or battery replacements over its service life?

No firmware or battery maintenance is required; the module is a passive DDR3 component that operates at 1.5V and has no onboard firmware or power source.

What thermal limit appears first when the registered ECC module runs at 1333 MHz continuously in a Dell Precision T5500?

The DDR3 chips are rated for 1.5 V operation; sustained full-load use will hit the JEDEC maximum case temperature before any electrical limit is reached.

How much power does the 8 GB 2Rx4 registered DIMM draw and how much heat does it add when the workstation runs all day?

At 1.5 V the module draws only a few watts, adding minimal heat; the registered buffer and ECC logic increase draw slightly over unbuffered DDR3 but remain well within the T5500 cooling capacity.
