FAQ's
What type of memory modules are included in the 408853-B21 kit? The kit includes two 2GB DDR2 ECC Registered DIMMs designed for server use, totaling 4GB of memory. What is the significance of ECC in this memory kit? ECC stands for Error-Correcting Code, which detects and corrects common types of internal data corruption, improving system reliability. Which servers are compatible with 240-pin DDR2 RDIMM modules? Servers that support DDR2 memory technology with 240-pin DIMM slots and registered ECC functionality can typically use these modules. Can this memory be installed in non-HP systems? Compatibility depends on motherboard support for 240-pin DDR2 ECC Registered DIMMs; it is primarily intended for HP servers. Does the 667MHz speed affect compatibility with existing memory? Memory speed must be supported by the server motherboard; mixing speeds can cause the system to default to the slowest module's speed. Is any special configuration needed to install this memory kit? Installation typically requires placing the modules into appropriate DIMM slots; BIOS settings may need checking to ensure correct recognition.
