8GB DDR4 ECC RDIMM for IBM-Lenovo

This 8GB DDR4 module is built for servers and workstations that require registered ECC memory. It delivers 2666MHz speed with CL19 latency at the standard 1.2V voltage. The 2Rx8 dual-rank organisation suits systems needing higher density per slot. It is a direct replacement for the IBM-Lenovo SBB7A01184 part number.

Registered ECC with 2Rx8 organisation

The single specification that decides fit is the registered ECC RDIMM format combined with a 2Rx8 rank structure. Unbuffered or single-rank modules will not work in platforms expecting this exact configuration. The 288-pin DDR4 DIMM form factor matches the physical slot, while the PC4-21300 rating confirms the 2666MHz data rate.

Steady throughput under sustained load

Registered buffering reduces electrical load on the memory controller, allowing stable operation when all slots are populated. ECC corrects single-bit errors in real time, preventing data corruption during long compute runs. The 1.20V standard voltage keeps power draw predictable across extended workloads. Quality testing ensures each module meets the stated timing and reliability targets.

Questions sur cet article

What does 2666MHz mean for my server's actual memory speed?

The module runs at 2666MHz, but the final operating speed is set by the platform's memory controller and the number of DIMMs populated per channel.

How does the PC4-21300 rating affect real-world throughput?

PC4-21300 is the JEDEC standard name for DDR4-2666; the memory controller and channel configuration determine the bandwidth you actually see.

Will this 288-pin DIMM fit my IBM-Lenovo server?

It uses the standard 288-pin DDR4 RDIMM form factor; verify your system's qualified vendor list for SBB7A01184 compatibility before installing.
