Server ECC RDIMM Upgrade

This 16GB DDR3L 1600 ECC Registered RDIMM is built for Supermicro A+ Server series 2022TC 2022TG 4022G and 4042G. It targets administrators who need registered error-correcting memory for workloads that demand data integrity. The module runs at 1.35V with CL11 latency and a 2Rx4 organisation. It will not work in standard desktop computers or alongside unbuffered DIMMs.

Simple DIMM Installation

Installation follows the usual 240-pin DDR3 DIMM procedure: power down the server, open the chassis, align the keyed notch and press firmly until the retention clips lock. No heat spreader is fitted, so clearance is minimal. The most common issue is mixing registered and unbuffered modules, which prevents the system from posting. Verify that every slot uses registered ECC RDIMMs before powering on.

Confirm Server Model First

Check that your chassis is one of the listed Supermicro A+ Server models before ordering. The motherboard must support DDR3L 1600 registered ECC memory and accept 2Rx4 modules at 1.35V. Do not assume compatibility with other Supermicro lines or with workstations that require unbuffered memory. If the system manual specifies a different rank or voltage, this module will not be suitable.
