64 GB DDR5 ECC RDIMM kit

This 64 GB kit contains two 32 GB DDR5 6400 MHz registered DIMMs built for the Supermicro SYS-122HA-TN-LCC server. Each module runs at 1.1 V with CL52 latency and 2Rx8 organisation. ECC and registered buffering protect data integrity in mission-critical workloads. No heat spreader is fitted.

Suited for capacity-bound server upgrades.

The kit targets administrators expanding memory in the named Supermicro Hyper SuperServer where registered ECC DDR5 is required. Systems that accept only unbuffered non-ECC modules cannot use this memory. Builders needing consumer SO-DIMMs or desktop UDIMMs should look elsewhere.

Registered ECC DDR5 at 6400 MHz CL52

The decisive specification is the registered ECC DDR5 6400 MHz CL52 288-pin RDIMM form factor at 1.1 V. Only motherboards qualified for this exact registered ECC DDR5 standard will POST with the kit. Verify the server memory QVL before purchase.

Questions about this item

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

Yes, the 288-pin DDR5 RDIMM form factor matches the registered DIMM slots on the Supermicro SYS-122HA-TN-LCC.

What BIOS setting or seating step is commonly missed when installing this 2Rx8 ECC RDIMM kit?

The modules must be fully seated until the retention clips click; then enable ECC in BIOS so the 2Rx8 registered chips can correct errors.

How do I know when a 32GB module in this 64GB kit needs replacement?

The server will log corrected ECC errors; rising uncorrectable counts or memory-test failures mean that specific 32GB module should be swapped.
