Combine memory modules together for better performance.
You can remove the RAM in your old system, even though it uses ECC-registered DDR3. The compatibility depends on the motherboard and chipset, not just the RAM type. Since you're replacing it with a different module, ensure the new RAM matches the specifications for your hardware.
ECC registration needs particular assistance to function properly, which isn't available at the consumer level.
Find boards advertising ECC support and ensure the CPU matches that requirement. Regular consumer devices typically lack this capability.
