Supermicro SYS-122HA-TN-LCC DDR5 RDIMM Kit

This 256GB kit supplies two 128GB DDR5 registered DIMMs built for the Supermicro SYS-122HA-TN-LCC server. Each module runs at 6400MHz with a CL52 latency and operates at 1.1V. The 2Rx4 organisation and ECC support target enterprise workloads that demand data integrity and high capacity per slot.

Upgrade Path From Lower-Capacity Registered DDR5

The kit replaces smaller RDIMM sets or mixed-capacity configurations that limit total memory on this platform. Moving to 2x128GB is worth it when applications need the full 256GB in a two-slot footprint and can benefit from the 6400MHz transfer rate. Systems already populated with slower registered DDR5 will not see a latency improvement because CL52 is fixed at this speed grade.

DDR5 RDIMM Electrical And Mechanical Limits

The 288-pin DDR5 RDIMM interface defines the key notch position, pin count and 1.1V signalling that this kit follows. Registered buffering adds a clock cycle of command latency, which is standard for server memory but prevents use in unbuffered desktop boards. The 2Rx4 rank structure fits the platform’s memory controller limits; exceeding the supported rank count per channel would prevent the system from posting.

商品問答

Will the 288-pin DDR5 RDIMM modules fit the Supermicro SYS-122HA-TN-LCC memory slots?

Yes, this kit uses the standard 288-pin DDR5 RDIMM form factor that matches the server's DIMM sockets.

What is the correct order for installing the two 128GB modules in the Supermicro SYS-122HA-TN-LCC?

Populate the slots indicated for channel A and channel B in the motherboard manual; the common mistake is placing both modules in the same channel.

When should the ECC RDIMM kit be replaced in a 24/7 Supermicro SYS-122HA-TN-LCC deployment?

Replace modules only if the system logs uncorrectable ECC errors or fails memory diagnostics during scheduled maintenance windows.
