System-specific DDR3 upgrade

This 16 GB kit contains two 8 GB registered ECC DIMMs built for the Dell Precision T5500 workstation. The modules run at DDR3 1333 (PC3-10600) with CL9 latency at 1.5 V. They are validated replacements for Dell part numbers A2984886, A2984887, A3198153, A3721483, A3858996, A4051416, A4051431, A4105734, A4188260, A4188265, A4188276, A6199968, A6996808, SNPP9RN2C/8G and SNPX3R5MC/8G.

Registered ECC 240-pin fit

The 240-pin RDIMM form factor requires a motherboard that supports registered ECC memory; standard desktop boards will not accept them. The kit cannot be mixed with unbuffered modules. Two slots are populated, leaving remaining slots available for further registered ECC expansion up to the platform limit.

Sustained workload stability

Registered buffering and ECC correction maintain data integrity during continuous multi-threaded tasks such as rendering, virtualization or database serving. The JEDEC-compliant 1.5 V operation keeps power draw predictable under long-duration load without voltage scaling.

Questions about this item

Does the registered ECC design limit the maximum capacity I can install in my Precision T5500?

The kit provides 16 GB as two 8 GB registered DIMMs; the T5500's chipset and CPU determine the actual ceiling, so consult the system manual for the supported total.

How much heat and power should I expect from these 1.5 V modules during continuous operation?

Each DIMM runs at the standard 1.5 V DDR3 voltage with no heat spreader, so thermal output matches typical registered DDR3 1333 modules under sustained load.

What must my Dell Precision T5500 already have for this 240-pin DDR3 kit to work?

The workstation must support DDR3 1333 registered ECC memory and provide free 240-pin DIMM slots; it cannot accept unbuffered or non-ECC modules alongside this kit.
