3 Things to Know About ECC Memory and Intel CPUs

Consumer Intel CPUs like the i7-9700K do not support ECC memory Intel locks ECC support to Xeon processors on consumer platforms. The memory controller in a Core i7 lacks the circuitry to use the extra bits, so ECC DIMMs will run as non-ECC.

You need a Xeon E-2200 series CPU for ECC on that board For actual error correction, use a Xeon E-2288G or similar. That is the only way to get ECC working on a board that claims support.

Always check the CPU’s official specs before buying ECC support is listed separately in the CPU specifications. Do not assume it is included.
