4800MHz Operating Frequency

The 4800MHz data rate represents a substantial increase over DDR4's maximum JEDEC specification of 3200MHz. This 50% improvement in base clock speed translates directly to higher bandwidth for data-intensive applications. For servers processing large datasets or running multiple virtual machines, this increased bandwidth ensures that the CPU remains fed with data, reducing bottlenecks and improving overall system responsiveness.

PC5-38400 Bandwidth Explained

The PC5-38400 designation indicates the module's peak transfer rate of 38,400 MB/s per module. This calculation derives from the data rate (4800 MT/s) multiplied by the bus width (64 bits) divided by 8 (bits to bytes conversion). In practical terms, this means each Dell 370-BCRS module can transfer approximately 38.4 gigabytes of data every second, making it ideal for memory-bandwidth-intensive workloads.

Critical Server Memory Features: ECC and Registered Design

Error Correcting Code (ECC) Technology

Enterprise servers cannot tolerate data corruption, which makes ECC (Error Correcting Code) memory essential for business-critical applications. The Dell 370-BCRS incorporates advanced ECC capabilities that can detect and correct single-bit errors automatically, while detecting multi-bit errors. This proactive error management prevents data corruption, system crashes, and silent data errors that could compromise business operations or analytical results.

ECC Protects Your Data

ECC memory adds extra bits to each word stored in memory, creating a checksum that validates data integrity during read operations. When the memory controller writes data, it calculates and stores the ECC code. Upon reading, it recalculates the code and compares it to the stored value. If a single-bit error is detected, it is corrected transparently without impacting system performance or requiring administrator intervention.

Registered DIMM (RDIMM) Architecture

The Dell 370-BCRS utilizes a Registered Dual In-Line Memory Module (RDIMM) design, which incorporates memory registers between the memory controller and DRAM chips. These registers buffer command and address signals, reducing electrical load on the memory controller and enabling support for higher memory capacities per channel and more DIMMs per system compared to unbuffered designs.

Benefits of Registered Memory in Servers

Registered memory provides several critical advantages for server environments: improved signal integrity, greater reliability at high capacities, and support for more memory modules per channel. This makes RDIMMs like the Dell 370-BCRS essential for servers requiring large memory configurations, such as database servers, virtualization hosts, and in-memory computing platforms that may utilize terabytes of RAM.
