What servers support the SM37B27362 memory module?

Compatible with Lenovo ThinkSystem ST250 V3 tower and SR250 V3 1U rack servers featuring Intel Xeon/Pentium processors and Rocket Lake/Raptor Lake PCH-S C266 chipsets. Supports up to 128GB total using 4x32GB modules with processor-limited 4400MHz operation.

Does this module support ECC error correction?

Yes, the SM37B27362 features full ECC with registered buffer and on-die correction, protecting against single-bit errors essential for enterprise reliability in virtualization and database environments. Meets ThinkSystem server RAS requirements.

What is the maximum speed this DIMM achieves?

Rated at DDR5-4800MHz (PC5-38400) with CL40 latency, but limited to 4400MHz by compatible server processors. Provides DDR5 bandwidth advantages over DDR4 in memory-intensive workloads.

What are the electrical specifications?

Operates at 1.1V low voltage in 288-pin RDIMM form factor with 2Rx8 dual-rank configuration using 16Gb DRAM dies. Reduces power consumption compared to 1.2V DDR4 while maintaining enterprise performance.

Can this memory be mixed with other DIMMs?

Yes, intermixable with other Lenovo TruDDR5 ECC UDIMMs/RDIMMs in supported ThinkSystem V3 servers, up to 128GB total capacity across four DIMM slots. Follow server memory population guidelines for optimal performance.

What workloads benefit most from this memory?

Ideal for virtualization hosts (vSphere/Hyper-V), database servers (SQL/Oracle), and edge computing nodes requiring high-capacity ECC RAM. Dual-rank design balances capacity and speed for sustained enterprise workloads.
