With more memory, the faster that data and instructions can be read, written, and performed by the server.

There are three types of memory DIMMS for servers available. These DIMM types cannot be mixed in a single system, you must select the type of DIMM appropriate for your workload at the type of purchase.

• Unbuffered DIMM: UDIMM, an unbuffered, low density, low-latency DIMM that doesn’t include a register or buffer chip. UDIMMs are generally used in applications requiring the lowest possible latency.
• Registered DIMM: RDIMM, a registered DIMM that provides high signal integrity — performing parity checking to detect improper addresses or commands — and increased performance for heavy workloads.
• Load reduced DIMMs: LRDIMM, uses a buffer to reduce memory loading to a single load on all DDR signals, allowing for greater density.

• Burn-in: Powered stress testing (i.e. increased temperature) to remove weak components.
• Component Test: Memory vendor-specific diagnostic tests performed at DRAM component level to ensure functionality.
• Module Test: Memory vendor-specific diagnostic tests performed at DIMM level to ensure functionality (with all DRAM components already mounted on DIMM PCB).
