Helpful Notes:
1. This memory module is compatible with servers and workstations that support DDR-266MHz PC2100 ECC registered memory.
2. ECC (Error Correcting Code) memory is designed to detect and correct single-bit errors, making it more reliable than non-ECC memory.
3. The dual rank feature of this memory module allows for better performance and more efficient memory usage in compatible systems.
