Description

The ThinkSystem TruDDR5 32GB RDIMM is DDR5 registered ECC server memory running at 4800MHz, built for AMD processor-based ThinkSystem servers (RDIMM-A). It uses a single-rank 1Rx4 organisation with a 9x4 (EC4) design, giving a 72-bit module made up of two 36-bit subchannels.

Lenovo TruDDR5 memory is tested and tuned in partnership with leading memory suppliers for ThinkSystem servers, and each module carries a unique Lenovo signature that the system can use to verify it. DDR5 bounded fault correction is supported to correct the most common DRAM failures. The 9x4 design does not support Single Device Data Correction (SDDC), so it offers lower fault tolerance than standard 10x4 RDIMMs.

Features

- Tested and tuned with leading memory suppliers for ThinkSystem servers
- Unique Lenovo signature programmed into the DIMM so the system can verify it
- DDR5 bounded fault correction to correct the most common DRAM failures
- 9x4 RDIMM design with lower fault tolerance than standard 10x4 RDIMMs (no SDDC)

FAQs

Q: Which servers is this memory designed for?
A: It is an RDIMM-A module for AMD processor-based ThinkSystem servers.

Q: What speed and capacity is this DIMM?
A: It is a 32GB DDR5 RDIMM running at 4800MHz.

Q: Does it support ECC?
A: Yes. It is a registered ECC DIMM with a 72-bit 9x4 design and supports DDR5 bounded fault correction.

Q: Does it support Single Device Data Correction (SDDC)?
A: No. SDDC is not supported on 9x4 RDIMMs, so fault tolerance is lower than on standard 10x4 RDIMMs.

Q: What does 1Rx4 mean?
A: It describes a single-rank module built with x4 DRAM devices.

Q: What is the Lenovo feature code for this module?
A: The feature code is BQ3E.
