Server Memory Kit

This 512GB kit contains four 128GB DDR5 4800 RDIMM modules built for Supermicro servers. ECC and registered operation provide the error correction and signal integrity required by mission-critical workloads. The kit is validated for the SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R platforms.

DDR5 4800 Interface Limits

DDR5 4800 sets the maximum transfer rate at PC5-38400 with a CL40 latency at 1.10V. Registered DIMMs add a clock cycle for buffering, so the memory controller must support registered ECC operation. Systems limited to lower speeds or unbuffered DIMMs cannot use this kit.

4Rx4 Rank Configuration

Each 128GB module uses a 4Rx4 organisation that increases density but places higher electrical load on the memory bus. The server motherboard must explicitly support 4Rx4 registered DIMMs at this capacity. Boards qualified only for 1Rx4 or 2Rx4 ranks will not recognise the full 512GB.

Questions sur cet article

Should I choose the 512GB kit or look for a smaller capacity?

The kit provides 512GB total across four 128GB modules. Choose it if your Supermicro server needs maximum registered ECC capacity; otherwise select a smaller kit that matches your workload.

What does the DDR5 4800 CL40 rating deliver in a live server?

It runs at 4800 MT/s with CAS latency 40 at 1.1V, giving registered ECC bandwidth suited for heavy multi-threaded workloads on compatible Supermicro platforms.

How does the 288-pin RDIMM interface limit speed or capacity?

The 288-pin DDR5 RDIMM form factor supports the 4800 MT/s spec and 4Rx4 organisation; registered buffering allows the 512GB kit capacity on qualified Supermicro motherboards.
