Product Description
The HP 664688-001B is a 4GB Registered Dual In-line Memory Module (RDIMM) designed for use in HP servers and high-performance workstations. It utilizes DDR3 SDRAM technology, operating at a speed of 1333MHz, which corresponds to a PC3-10600 designation. This module is engineered to provide reliable and efficient memory performance for demanding enterprise workloads. The RDIMM form factor includes an onboard register that buffers data signals between the memory controller and the DRAM chips. This buffering reduces electrical load on the memory controller, allowing for more memory modules to be installed in a system and improving overall stability, especially in systems with a large number of memory slots. The CAS Latency (CL) of 9 indicates the number of clock cycles it takes for the memory module to respond to a column address strobe command. With a 1Rx4 configuration, this module consists of a single rank of memory chips, with each chip organized as x4 (four data bits wide). This configuration is common in server memory and is optimized for performance and density. The HP 664688-001B is a crucial component for upgrading or maintaining the memory capacity and performance of compatible HP ProLiant servers and other enterprise-grade systems.
