Servers that require RDIMMs will not POST with it.- ECC operation needs a platform that supports ECC UDIMMs (e.g. Xeon E, many AMD Ryzen/EPYC boards, workstation/server boards). On most consumer desktop boards it runs as standard non-ECC RAM if it runs at all — check your board's QVL/manual first.WHAT'S INCLUDED- One KSM32ED8/16HD stick per unit purchased (quantity 2 available), shipped in an anti-static bag inside a padded, rigid mailer. Photos show a representative stick.SHIPPING & RETURNS- Free USPS shipping, within 2 business days of cleared payment.- No returns — please verify UDIMM/ECC compatibility before buying.
