Compatible Oracle-Sun 7082851 Replacement

This 32 GB DDR4 module replaces Oracle-Sun part 7082851 in supported servers and workstations. It delivers ECC Load Reduced DIMM operation for data integrity in mission-critical workloads. The single-module design simplifies capacity scaling in qualified platforms. Verify your system documentation before ordering.

Thermals Noise and Power Draw

Standard 1.2 V DDR4 voltage keeps power draw within typical server memory limits. Load Reduced buffering reduces electrical load on the memory bus without adding active cooling requirements. Passive operation produces no audible noise in normal chassis airflow. CAS latency CL15 aligns with DDR4 2133 timing specifications.

Upgrade Path and Value

This module upgrades systems currently populated with lower-capacity DDR4 2133 LRDIMMs that share the same rank and voltage profile. The jump is worthwhile when workloads exceed existing memory capacity and the platform supports 4Rx4 organisation. Buyers needing different speeds, ranks or non-ECC memory should look elsewhere.

Questions about this item

How do I install this 288-pin DDR4 LRDIMM and which slot population rule do people overlook?

Align the notch on the 288-pin edge connector with the key in the motherboard slot, press firmly until both retention clips click, and populate slots in the order specified by the server manual — typically one module per channel before adding a second rank to the same channel.

What maintenance or replacement will this 4Rx4 ECC module need over its service life?

No periodic maintenance is required; the module either passes POST and runs error-free or it develops correctable ECC errors that the firmware logs — if uncorrectable errors appear, replace the module.

At what point does the 1.2 V 2133 MHz CL15 rating become the limiting factor during sustained workloads?

The JEDEC-standard 1.2 V / 2133 MHz / CL15 timing ceiling is reached first; the memory controller cannot push frequency or tighten latency beyond this spec without violating DDR4 electrical limits.
