How to install Lenovo RAM Module

• Power down the server completely, unplug from power sources, and discharge static from your body by touching a grounded metal surface before handling memory modules.
• Open the server chassis and locate the appropriate memory slots. Verify you are working with compatible DDR5 slots designed for 288-pin DIMMs and that the board supports the registered memory you’re installing.
• If you are adding memory, depress the slot latches to expose the socket. If you are replacing an existing module, carefully release the end latches to disengage the old DIMM before inserting the new one.
• Align the notch on the Lenovo RAM Module with the keying in the socket, insert the DIMM at a slight angle, and then press down evenly until the latches click into place and the module is firmly seated.
• Power on the server and enter the BIOS or UEFI setup to confirm the new memory is detected. Run a memory assessment or system health check to verify stability and total available capacity (256 GB per module). If any issues arise, re-seat the module or test in another slot to isolate a potential compatibility or seating problem.

Frequently asked questions

• Q: What systems is the Lenovo RAM Module compatible with?
• A: This module is designed for server use with DDR5-4800 memory and a 288-pin DIMM form factor. Compatibility depends on the server chassis and motherboard memory support. Check your server’s memory compatibility list or Lenovo support resources to ensure the motherboard and BIOS/firmware support DDR5 registered memory in octal-rank configurations.
• Q: How many modules do I need to reach a certain total memory capacity?
• A: To achieve a target total memory, multiply the number of modules by 256 GB per module. For example, four modules yield 1 TB of RAM (256 GB × 4). Ensure your server supports the total number of DIMMs and that interleaving and memory channels are balanced for optimal performance.
• Q: What is TruDDR5 and why is it beneficial?
• A: TruDDR5 is Lenovo’s branding for DDR5 memory technology that delivers higher bandwidth and improved efficiency over previous generations. It enables faster data transfer rates, lower power consumption, and better performance in memory-heavy workloads such as virtualization, databases, analytics, and real-time processing.
• Q: Do I need a BIOS update to use DDR5 RAM?
• A: In some cases, server platforms require a BIOS/firmware update to recognize and fully optimize DDR5 memory. Always verify compatibility and perform any recommended BIOS updates from the server manufacturer before installing new memory modules.
• Q: How should I configure memory when using multiple Lenovo RAM Modules?
• A: For best performance, install memory modules in matched sets across memory channels to maintain balanced interleaving. Refer to your server’s memory topology documentation to maximize bandwidth and stability with the octal-rank modules.
