Frequently Asked Questions

What is Dual Rank x4 and why does it matter?

Dual Rank x4 means the DIMM has two ranks of x4-width DRAM chips. x4 chips support SDDC (Single Device Data Correction) for enhanced RAS, making them preferred for mission-critical server deployments over x8 chips.

Is this compatible with non-Lenovo servers?

This is an OEM Lenovo ThinkSystem RDIMM validated for ThinkSystem servers. Compatibility with non-Lenovo servers is not guaranteed.

Can DDR4-2933 RDIMMs run in DDR4-3200 servers?

Yes, DDR4-2933 modules can run in DDR4-3200 servers but will operate at DDR4-2933 speed. For maximum performance, use DDR4-3200 RDIMMs in DDR4-3200 platforms.

The Lenovo 01KR355 delivers 32GB of DDR4-2933 ECC Registered server memory in a dual rank x4 configuration — validated for Lenovo ThinkSystem servers requiring reliable RDIMM for DDR4-2933 enterprise deployments.
