Buyers needing a used CPU for LGA1151 boards

This unit suits builders replacing a failed processor in an existing LGA1151 system or upgrading an older platform on a budget. It is not for buyers who require a new-in-box component with original accessories and full manufacturer warranty coverage.

LGA1151 socket compatibility

The processor fits only motherboards equipped with an LGA1151 socket and a compatible chipset. Verify the board's CPU support list before purchase because not every LGA1151 board accepts this 6-core model.
