Questions & Answers
What are the key specifications of Lenovo ThinkSystem 16GB TruDDR4 2666 MHz RDIMM?
The Lenovo ThinkSystem TruDDR4 RDIMM offers 16 GB capacity, 2666 MHz clock speed, 1.2 V operating voltage, 2Rx8 rank configuration, and full ECC support.
Which Lenovo servers are compatible with part number 7X77A01303?
Part number 7X77A01303 is validated for Lenovo ThinkSystem SR650, SR630, SR590 and select Flex System compute nodes.
How does TruDDR4 technology improve system performance?
TruDDR4 optimizes memory trace routing and power delivery, delivering higher bandwidth, reduced latency, and improved signal integrity.
Is the 16GB TruDDR4 2666 MHz RDIMM ECC-protected?
Yes. It features full ECC (Error-Correcting Code) to detect and correct single-bit memory errors in real time.
Can I mix this RDIMM with UDIMM or LRDIMM modules?
No. Lenovo requires using identical RDIMMs across all memory slots. Mixing RDIMM with UDIMM or LRDIMM is not supported.
What is the difference between registered and unbuffered DIMMs?
Registered DIMMs (RDIMMs) include a register to buffer and stabilize command/address signals for higher capacity and reliability, unlike unbuffered DIMMs (UDIMMs).
How many modules of this memory can I install per server?
Server support varies by model. For dual-processor servers, you can typically install up to 24 modules per node, populated according to the server’s memory population rules.
What is the operating voltage of Lenovo ThinkSystem 16GB TruDDR4 2666 MHz RDIMM?
The operating voltage is 1.2 volts, ensuring energy efficiency and reduced heat generation.
Does Lenovo offer a warranty for this 16GB RDIMM?
Yes. It carries Lenovo’s standard three-year limited warranty with global service and support options.
How do I install the 16GB TruDDR4 2666 MHz RDIMM?
Power off the server, open the chassis, align the notch to the DIMM slot, press until the latches click, then close the chassis and power on.
What temperature range does this memory support?
It operates reliably between 0 °C and 85 °C (32 °F to 185 °F) under standard server environmental conditions.
Can I overclock the 2666 MHz speed on Lenovo servers?
No. Lenovo server BIOS enforces JEDEC specifications and does not support memory overclocking beyond 2666 MHz.
How does the 2Rx8 rank configuration affect performance?
The 2Rx8 dual-rank design improves parallelism and overall bandwidth versus single-rank modules, boosting multitasking workloads.
What is the part number for ordering a single 16GB TruDDR4 RDIMM?
Order part number 7X77A01303 for a single 16 GB TruDDR4 2666 MHz 2Rx8 RDIMM module.
Are firmware updates required for this memory module?
Memory firmware updates are managed through Lenovo XClarity Controller or IMM; ensure the server BIOS is up to date for best compatibility.
How can I verify that my server recognizes the new RDIMM?
Enter the server BIOS or use Lenovo XClarity Administrator to view installed memory modules and confirm capacity, speed, and ECC status.
