8GB DDR4-2133 Registered ECC Module

This 8GB DDR4-2133 registered ECC module targets server and workstation builds that require error correction and signal buffering. The 1Rx4 organisation and 1.20V operation suit density-optimised platforms. It is not for desktop boards that lack registered DIMM support or for users who need non-ECC memory.

Supermicro Certified Validation

Supermicro certification confirms the module passes the vendor’s qualification suite for compatible platforms. The RoHS declaration covers restricted-substance compliance. No extra software, heat spreaders or cables are bundled with the memory.

288-Pin LP Form Factor Install

The low-profile 288-pin DIMM fits standard DDR4 registered slots without height clearance issues. Alignment keys prevent mis-insertion. The most common issue is populating slots in an order the motherboard manual does not support for registered DIMMs.

Questions about this item

Will the 1Rx4 registered ECC module need any firmware updates or preventive replacement over its service life?

The 1Rx4 registered ECC module has no moving parts and requires no firmware updates or scheduled replacement under normal server operation.

What thermal limit appears first when the 8 GB DDR4-2133 DIMM runs at 1.20 V continuously?

The 1.20 V DDR4-2133 DIMM stays within JEDEC thermal limits; the first constraint is the server chassis airflow keeping the module below its maximum case temperature.

How much power does the 288-pin DDR4-2133 module draw and how much heat does it add when the system runs all day?

At 1.20 V the 8 GB registered module typically draws a few watts, adding minimal heat that standard server cooling handles without extra fan noise.
