System-Specific DDR4 Upgrade

This 32GB DDR4 2666 module is built for Supermicro SuperBlade 4119MG-X and listed X11 motherboards. It targets administrators who need ECC protection in a very-low-profile form factor. The single DIMM delivers 32GB of unbuffered memory at 1.2V.

JEDEC Standard Limits

The module follows JEDEC DDR4 2666 PC4-21300 specifications with CL19 latency and 2Rx8 organisation. Maximum throughput is defined by the 2666 MT/s rating; the platform cannot exceed this speed. ECC function operates only on motherboards that support unbuffered ECC DIMMs.

2Rx8 Rank Configuration

The dual-rank 2Rx8 layout is the specification that determines compatibility with the target Supermicro boards. Systems requiring single-rank modules or registered DIMMs will not accept this part. Verify the motherboard qualification list before purchase.

Questions about this item

Should I pick the 32 GB module or add smaller DIMMs to reach the same total?

The module is a single 32 GB DDR4 2666 CL19 2Rx8 VLP ECC unbuffered DIMM; matching capacity, speed, rank and voltage across all slots gives the most stable operation.

What does the 2666 MT/s rating deliver in a Supermicro X11SCM-F or SuperBlade 4119MG-X?

The memory runs at the JEDEC-standard 2666 MT/s with CL19 latency at 1.2 V, providing the rated throughput for those platforms without overclocking.

How does the 288-pin DDR4 2666 interface limit performance in these systems?

The 288-pin DDR4 2666 interface operates at the standard 2666 MT/s data rate; actual throughput depends on the memory controller and channel population of the specific Supermicro board.
