Server-ready DDR5 kit

This 64 GB kit contains four 16 GB DDR5-4800 registered ECC RDIMMs built for the Supermicro H13SRH motherboard. Each module runs at 1.10 V with CL40 latency and a 1Rx8 organisation. The registered design lets the board run every slot fully populated at rated speed.

Replaces mismatched or slower DIMMs

Swapping mixed-capacity or lower-speed modules for this matched quad-channel set restores the bandwidth and error-correction the platform expects. The upgrade is worthwhile when the current configuration limits total memory or forces the controller to down-clock.

Tool-free press-in install

Align the 288-pin key notch with the slot and press evenly until the retention clips lock. Common issues are seating modules in the wrong population order or mixing registered and unbuffered DIMMs, both of which prevent the system from posting.
