201694-B21 HP 1GB 133MHz ECC Registered 168-Pin DIMM Memory

The 201694-B21 HP 1GB 133MHz ECC Registered DIMM is a memory module designed to provide system memory for servers and workstations. It uses error-correcting code (ECC) to detect and correct common types of internal data corruption, which is important in environments where data integrity is critical.

This memory module fits into systems that accept 168-pin DIMMs and operates at a clock speed of 133MHz with a 3.3V power requirement. It is registered, meaning it includes a register between the DRAM modules and the system's memory controller to improve stability in multi-memory configurations.

• 1GB DDR memory capacity
• 133MHz operating frequency
• Error-Correcting Code (ECC) support
• Registered DIMM design for stability
• 168-pin DIMM form factor with 3.3V power rating

This memory module is typically used to expand or replace system memory in compatible HP servers that require ECC registered modules at this specification. Its design helps maintain system stability and data integrity in critical computing environments.
