- Expand server memory capacity with 128 GB per module
Increase server capacity where it matters most: in the memory layer. This Samsung 128 GB DDR4 registered module is designed for platforms that need high-density expansion without compromising stability. Running at 2,400 MHz with ECC protection, it supports demanding workloads such as virtualization hosts, database servers, and application platforms that benefit from large, reliable memory pools.
The registered DIMM design helps maintain signal integrity in systems built for larger memory footprints, making it a strong fit for enterprise deployments that need predictable behavior under load. With 128 GB on a single module, it reduces the number of slots required to reach higher capacities, preserving upgrade paths for future growth.
For infrastructure teams, that means fewer compromises. You get the capacity to keep more data active in memory, the error correction needed for uptime-sensitive environments, and the Samsung manufacturing pedigree expected in long-life server deployments. This is the kind of memory upgrade that pays off in fewer bottlenecks, cleaner scaling, and more room for critical workloads to run without constant tuning.
Ideal For
- Virtualization hosts needing larger memory pools
- Database servers running memory-intensive queries
- Application servers supporting concurrent enterprise workloads
- Rack servers where slot efficiency matters
Why This Product
- 1Higher capacity than standard 32 GB and 64 GB modules
- 2ECC registered design for server stability
- 32,400 MHz speed for balanced enterprise performance
- 4Single 128 GB module reduces slot usage
