FAQ's
What systems are compatible with the 820077-B21 memory? This module is compatible with HP servers and workstations that support 4GB DDR3 1600MHz ECC UDIMM memory with a 240-pin configuration and 1.5V operating voltage. What does ECC mean in this memory module? ECC stands for Error Correction Code, a technology that detects and corrects single-bit memory errors to improve data reliability and system stability. Is the 820077-B21 a registered or unbuffered DIMM? The 820077-B21 is an unbuffered DIMM (UDIMM), not a registered or buffered memory module, designed for specific HP systems that support UDIMM. What is the significance of the 240-pin specification? The 240-pin configuration refers to the physical interface and form factor of the DDR3 UDIMM, ensuring compatibility with motherboards designed for this type of memory. Does this memory module require a specific voltage? Yes, it operates at 1.5 volts, which aligns with standard DDR3 specifications for UDIMMs to ensure proper electrical compatibility. Can this memory be used in non-HP systems? Compatibility with non-HP systems depends on the motherboard’s support for 4GB DDR3 1600MHz ECC UDIMM modules with a 240-pin form factor and 1.5V operation, but this module is primarily designed for HP systems.
