- Expand server capacity with 128 GB DDR5 memory for demanding workloads
Scale memory capacity without compromising platform stability. Samsung’s 128 GB DDR5-4800 RDIMM is built for servers that need more room for virtual machines, database caches, and large application sets. The registered design helps maintain signal integrity in populated memory channels, while ECC support adds another layer of protection against data errors that can disrupt critical workloads.
Running at 4,800 MT/s and 1.1 V, this module balances throughput and efficiency for modern DDR5 platforms. The 4Rx4 organization is suited to high-capacity deployments where memory density matters as much as performance. For infrastructure teams, that means fewer compromises when consolidating workloads or expanding capacity in systems already under pressure.
Choose this module when the cost of downtime, latency, or memory contention is higher than the price of premium server-grade RAM. It is a strong fit for environments that need predictable behavior under load, not consumer-grade shortcuts.
Ideal For
- Virtualization hosts requiring higher VM density
- Database servers needing larger in-memory working sets
- Enterprise application servers with sustained memory pressure
- Rack-mounted systems standardizing on DDR5 RDIMM upgrades
Why This Product
- 1Higher capacity than 64 GB modules for VM consolidation
- 2DDR5-4800 speed supports modern server platforms
- 3Registered ECC design suits mission-critical systems
- 44Rx4 density targets enterprise memory expansion
