FAQ's
Is the HP 647895-B21 compatible with all HP servers? Compatibility depends on the server model and its support for DDR3 1600MHz ECC RDIMM memory. It is designed for HP servers that accept 240-pin DDR3 ECC registered DIMMs. Verify the server specifications before installation. What does ECC RDIMM mean on this memory? ECC stands for Error-Correcting Code, which helps detect and correct common data corruption. RDIMM means Registered DIMM, a memory type with a register that improves signal stability in multi-module configurations, commonly used in servers. Can this module be used in non-server desktop computers? This module is intended for servers requiring ECC registered memory. Most standard desktop systems do not support ECC RDIMM modules, so it is not suitable for typical consumer desktops. What voltage does the HP 647895-B21 operate at? This memory module operates at 1.5 volts, which is standard for DDR3 memory modules of this type. Ensure the system supports this voltage for proper operation. How many pins does this memory module have? The HP 647895-B21 module features 240 pins, designed to fit DDR3 DIMM slots in compatible server motherboards. What memory speed does this module support? The module runs at 1600MHz, which is typical for DDR3 memory and should be supported by servers designed for this speed.
