FAQ
What is the capacity and technology of this memory module?
This is a 4GB DDR3 SDRAM module operating at 1333 MHz speed. It uses DDR3 memory technology with a PC3-10664 memory standard, providing 4 gigabytes of memory capacity in a single module configuration suitable for server memory expansion.
Does this memory support ECC and what are the benefits?
Yes, this module features Error-Correcting Code (ECC) functionality. ECC detects and corrects single-bit memory errors that can occur during data storage and retrieval, preventing data corruption and system crashes in server environments where memory reliability is critical for continuous operation.
What does 'Registered' mean in this memory specification?
Registered memory includes a register between the memory modules and the memory controller. This register buffers address and command signals, reducing electrical load on the memory controller and enabling support for more memory modules per channel. This design enhances signal integrity and stability in server configurations with multiple memory modules.
What form factor and pin configuration does this module use?
This module uses a 240-pin DIMM (Dual In-line Memory Module) form factor, which is the standard physical configuration for server memory. The 240-pin design ensures proper electrical contact and mechanical compatibility with server memory slots designed for DDR3 memory technology.
What is the CAS latency and how does it affect performance?
This memory module has a CAS latency of CL9, which represents the number of clock cycles between a read command and data availability. Lower CAS latency values generally provide faster response times for memory access operations. The CL9 rating balances performance with the reliability requirements of server-grade memory operating at 1333 MHz.
Is this memory compatible with specific server systems?
This module is manufactured as a compatible factory-original replacement for HP servers requiring 652491-171 compatible memory. It maintains the exact specifications including 4GB capacity, DDR3-1333MHz speed, 240-pin DIMM form factor, 1.5V operation, and registered ECC architecture required for seamless integration with compatible HP server systems.
