About the Samsung 64GB DDR4 RDIMM - DDR4 (M393A8K43DB3-CTD)
CL21 timing at 1.2V — this Samsung DDR4 RDIMM delivers the low-latency performance critical for high-frequency trading platforms, in-memory databases, and real-time analytics workloads. The M393A8K43DB3-CTD is a 64GB registered DIMM module running at 2933 MT/s (PC4-23400), engineered for mission-critical enterprise servers where reliability and speed converge. Built by Samsung, this 288-pin module features dual-rank (2Rx4) architecture and full ECC support, ensuring data integrity across demanding infrastructure deployments.
Designed for storage architects, database administrators, and IT infrastructure teams, this Samsung memory module scales to 3TB+ per server in multi-socket systems. The 31.25mm form factor fits standard rack configurations, while the 0–85°C operating envelope supports both climate-controlled datacenters and edge deployments. The 72-bit data path (64-bit + 8-bit ECC) and registered design reduce signal noise in dense memory configurations, making the M393A8K43DB3-CTD ideal for hyperscale deployments, virtualization hosts, and enterprise applications requiring sub-microsecond response times. Low power consumption at 1.2V minimizes thermal load in high-density server builds.
Enterprise Deployment Scenarios
- In-memory databases (Redis, Memcached) requiring predictable sub-100ns latency
- High-frequency trading systems and quantitative finance infrastructure
- Virtualization platforms (VMware, Hyper-V) with 100+ concurrent workloads
- Data warehousing and columnar analytics (Vertica, SAP HANA)
- Machine learning model inference clusters with strict throughput SLAs
