Server DDR3 32GB ECC RDIMM

This 32GB DDR3 module runs at 1066MHz (PC3-8500) with a CL3 latency and 1.5V operation. It is a registered ECC DIMM built with a 4Rx4 organisation for server and workstation platforms. The 240-pin form factor fits DDR3 DIMM slots in compatible systems. It serves as a direct replacement for the Hynix HMT84GR7MMR4C-G7 part.

4Rx4 registered design impact

The 4Rx4 rank structure increases memory density per slot, allowing higher total capacity in systems with limited DIMM sockets. Registered buffering reduces electrical load on the memory controller, which helps stability when multiple modules are populated. ECC capability detects and corrects single-bit errors to protect data integrity in critical workloads.

DDR3 slot and platform check

Verify that your motherboard or server chassis supports DDR3 RDIMM modules at 1066MHz with 4Rx4 ranking and 1.5V voltage. Confirm the maximum supported capacity per slot and total system limit in the vendor documentation. Ensure the BIOS or firmware is current enough to recognise high-density registered ECC DIMMs before installation.

Questions sur cet article

Will the registered ECC module require any periodic maintenance or component replacement during its service life?

The module has no moving parts or user-serviceable components, so no scheduled maintenance or replacement is needed under normal operation.

What electrical or thermal limit is reached first when the DIMM runs continuously at 1.5 V and 1066 MHz?

The 1.5 V supply rail and the registered buffer's current rating set the primary electrical ceiling; thermal limits follow the system's airflow design.

How much heat and acoustic output should I expect from this 32 GB DDR3 RDIMM in a 24-hour server workload?

The module itself is silent and its power draw at 1.5 V is modest; total heat and noise depend on the chassis cooling and other installed components.
