3 Things to Know About ECC RAM and a B660 Board With an i5-12600K

ECC RAM won’t work on a B660 board with an i5-12600K Intel only supports unbuffered ECC on 12th-gen consumer CPUs with a W680 chipset, not B660.

The BIOS and memory controller on B660 boards disable ECC functions Even if you install ECC DIMMs, they will likely run in non-ECC mode or fail to boot entirely.

Rare exceptions exist but are not reliable Some manufacturers may have a B660 board that technically allows ECC, but this is uncommon. For error correction, use a W680 board or a Xeon with a C-series chipset.
