System-specific DDR3L kit for Lenovo ThinkServer

This 32GB kit contains four 8GB DDR3L 1600 registered DIMMs built for the Lenovo ThinkServer RD440. Each module runs at 1.35V with CL11 timing and ECC error correction. The 240-pin form factor fits the server's 12 DIMM slots across two CPUs.

Steady throughput under continuous server workloads

Registered buffering and ECC keep data integrity intact during sustained read and write cycles. The modules operate at DDR3L 1600 (PC3L 12800) and will clock down automatically if the installed processor or population rules require a lower speed. Low voltage reduces heat during 24/7 operation.

240-pin registered DIMMs without heat spreaders

The bare green PCB allows tight side-by-side population in all six channels per CPU. Major-brand DRAM chips are used throughout the 2Rx4 rank layout. Compatibility is validated for the RD440 platform supporting up to 192GB total capacity.

Questions about this item

How much heat or power draw should I expect from the 1.35 V DDR3L modules running continuously in a ThinkServer RD440?

The low-voltage DDR3L design operates at 1.35 V instead of the standard 1.5 V, reducing power consumption and heat output during all-day server workloads.

Does my ThinkServer RD440 need any specific CPU configuration or BIOS version to recognise all four 8 GB registered DIMMs?

The RD440 supports up to 192 GB across 12 slots with two CPUs; populate the six slots per CPU in the order shown in the system manual for full 32 GB recognition.

Will these CL11 2Rx4 registered sticks work alongside any older DDR3 ECC modules I already have installed in the same server?

Faster memory clocks down to the optimal speed and voltage for the installed processor and module count, so mixed kits will run at the lowest common timing.
