- DDR4-2666 / PC4-21300 data rate
- ECC memory for error detection and correction
- DIMM form factor
- Samsung-manufactured server memory module
- CL15 latency
- Compatible with enterprise server memory slots
- Increase server headroom with 16 GB capacity for active workloads
Keep critical workloads moving with 16 GB of DDR4-2666 server memory designed for systems that need consistent throughput and error-aware operation. This Samsung module pairs ECC protection with PC4-21300 bandwidth, helping infrastructure teams add capacity without compromising stability under sustained load.
For virtualization hosts, application servers, and general-purpose enterprise systems, the value is in the balance: enough speed to support active workloads, enough reliability to reduce avoidable interruptions, and a capacity point that fits practical upgrade plans. DDR4-2666 is a strong fit for environments where memory pressure affects response times, but overprovisioning would add cost without clear return.
Use this module when you need a clean, standards-based upgrade path for compatible server platforms. It is a straightforward choice for extending service life, improving headroom for concurrent processes, and keeping procurement aligned with proven hardware rather than speculative performance claims.
Ideal For
- Upgrade HPE server memory for virtualization hosts
- Add capacity to application servers under sustained load
- Replace aging DIMMs in enterprise infrastructure refreshes
- Expand memory headroom in general-purpose rack servers
Why This Product
- 1ECC support adds protection not found in basic desktop memory
- 2DDR4-2666 offers stronger bandwidth than slower 2133 MHz modules
- 316 GB capacity suits targeted server upgrades without overspending
- 4DIMM server memory is built for infrastructure use, not consumer PCs
