Frequently Asked Questions
What servers is this DDR3 ECC memory compatible with?
The Hynix HMT84GR7MMR4A-G7 is designed for HP ProLiant servers that support PC3L-8500R DDR3 registered ECC memory. Compatibility includes ProLiant DL360, DL380, DL560, and DL580 series. Always verify your specific server model's memory support documentation before purchasing.
Why choose registered ECC memory for servers?
Registered ECC memory provides two critical advantages: error correction code (ECC) detects and corrects single-bit memory errors automatically, preventing data corruption, and registered buffering reduces electrical load on the memory controller, enabling larger memory configurations and improving system stability in enterprise environments.
What does PC3L-8500R mean?
PC3L-8500R indicates DDR3 memory with 8500 MB/s bandwidth (1066MHz speed) and low voltage (1.35V) operation. The 'R' denotes registered memory with buffering. This specification ensures compatibility with HP ProLiant servers designed for this memory standard.
Can I mix this 32GB module with other memory sizes?
Yes, you can mix different capacity DDR3 ECC modules in ProLiant servers, but for optimal performance, HP recommends using matched memory configurations. Ensure all modules are the same speed (1066MHz), voltage (1.35V), and type (registered ECC) for best results.
