EXACT-MATCH UPGRADE — 64GB (4X16GB) kit DDR4-2666 (PC4-21300), 1Rx4 Registered ECC, 1.2V, CL19, 288-pin. The precise rank, voltage, and timing your server's memory controller expects, so it's recognized at full capacity and runs at its rated speed.
VERIFIED FITMENT — Compatible with Xeon Scalable, PowerEdge, ProLiant, ThinkSystem, Supermicro. Spec-matched to your board's memory-population rules.
ENTERPRISE STABILITY — Registered (buffered) architecture offloads the memory controller so every slot runs fully populated at full capacity, while ECC catches and corrects single-bit errors on the fly — stopping silent data corruption and unplanned reboots before they reach production.
CHECK YOUR CONFIG — Server and motherboard memory support varies by model. Consult your system or motherboard manual for supported capacities, approved DIMM population order, and installation steps before purchase.
LIFETIME SUPPORT — Backed by a lifetime replacement warranty and free US-based technical support.
