System-Specific Upgrade Kit

This 12 GB kit contains three 4 GB DDR3 ECC Registered DIMMs built for the Dell Precision Workstation T5500. It targets administrators maintaining legacy Xeon servers that require registered memory with error correction.

Registered ECC at 1333 MHz

Each module runs at PC3-10600 speed with CL9 9-9-9 timings at 1.5 V. The 2Rx4 organisation and registered buffer mean the memory controller must support registered ECC; unbuffered ECC modules cannot be mixed in the same system.

Six-Slot Triple-Channel Platform

The T5500 provides six DIMM sockets per processor, expandable to nine with the optional riser card. Registered ECC allows up to 48 GB per CPU, but 1333 MHz operation is only guaranteed with one DIMM per channel on Xeon X5550 or higher processors; slower Xeons or fuller banks will downclock to 1066 MHz or 800 MHz.

Preguntas sobre este artículo

What does the 1333 MHz speed mean once this kit is installed in a Dell Precision Workstation T5500?

The kit runs at 1333 MHz when one DIMM per channel is used with a Xeon X5550 or higher processor. Adding more modules or using a lower-grade Xeon will drop the speed to 1066 MHz or 800 MHz.

How does the DDR3 1333 (PC3 10600) registered ECC interface affect usable performance in this system?

Registered ECC modules are required for capacities above 24 GB. The T5500 accepts both registered and unbuffered ECC, but they cannot be mixed. Registered DIMMs allow up to 48 GB, or 72 GB with the optional riser card.

What physical requirements must the T5500 meet to accept these 240-pin DIMMs?

The workstation has six DIMM sockets, or nine with the optional riser card. This three-stick kit occupies one triple-channel bank. Modules must be installed in matched sets per channel for full 1333 MHz operation.
