Target System Compatibility

This 8GB DDR3 module is built specifically for the Dell Precision R5500 workstation. It uses a 240-pin RDIMM form factor with ECC registered architecture required by that platform. The part will not function in standard desktop motherboards or systems that require unbuffered memory.

Sustained Workload Stability

ECC registered design detects and corrects single-bit errors during continuous operation, protecting data integrity in server and workstation environments. Registered buffering reduces electrical load on the memory controller, allowing stable performance when the system runs at full capacity for extended periods.

Registered ECC Requirement

This module only works in systems that support DDR3 1333 registered ECC memory; it cannot be mixed with unbuffered DIMMs. Buyers whose platforms need standard desktop memory must choose a different type.

Questions about this item

How much power does the 1.5V DDR3 module draw when the Precision R5500 runs continuously?

The module operates at 1.5V; actual power draw depends on the R5500 workload and memory controller configuration.

What must the Dell Precision R5500 already have to accept this 240-pin ECC registered DIMM?

The R5500 must support DDR3 1333 registered ECC memory and provide free 240-pin DIMM slots.

Can this CL9 2Rx4 registered stick run alongside older unbuffered DDR3 modules in the R5500?

No, registered ECC memory cannot be mixed with unbuffered modules in the same system.
