16GB DDR4 ECC VLP UDIMM for Supermicro MicroBlade

This 16GB DDR4 2666 CL19 module is built for the Supermicro MicroBlade 6119M-C2 and 6219G-T. It uses 2Rx8 unbuffered ECC chips on a 288-pin VLP PCB at 1.2V. The part number is 2E6V42R816GB. It targets administrators who need JEDEC-compliant, warranty-safe capacity increases for those specific blade servers.

Fits a 288-pin DDR4 slot on the listed MicroBlade

The very low profile height clears tight blade enclosures without blocking airflow. ECC protection guards data integrity in multi-node deployments. Unbuffered design keeps latency low for the supported platforms. One module adds 16GB per slot, letting you scale memory independently of CPU or storage changes.

Replaces lower-capacity DDR4 ECC VLP UDIMMs

The upgrade is worthwhile when workloads exceed the current memory ceiling and cause swapping or throttling. It does not suit systems that require registered DIMMs, non-ECC modules, or a different pin count. Buyers needing larger single-module densities or faster speeds must verify platform support before purchasing.

Questions about this item

Will the VLP height fit inside my Supermicro MicroBlade 6119M-C2?

Yes, the VLP form factor is built for the tight clearance of the Supermicro MicroBlade 6119M-C2 and 6219G-T chassis.

Does the module run hot or draw extra power in a fully populated blade?

At 1.2 V and without a heat spreader, it stays within standard DDR4 thermal limits during continuous operation.

Must the blade already have matching DDR4 ECC UDIMMs for this upgrade to work?

For best stability, populate all slots with identical 16 GB DDR4 2666 CL19 2Rx8 ECC unbuffered modules.
