System-specific memory kit

This 16GB kit contains two 8GB registered DDR3L DIMMs built for the Lenovo ThinkServer RD340 series. It runs at 1600 MHz with CL11 timing at 1.35V and includes ECC error correction for server workloads.

Check your server before ordering

Verify that your RD340 uses part numbers 70A9xxx, 70AAxxx or 70ABxxx and has free 240-pin DIMM slots. The system accepts up to 192GB across six sockets per CPU, so confirm available slots and current population before adding this kit.

Upgrade from base configuration

The RD340 ships with 4GB removable memory; this kit quadruples that starting capacity in a single step. The jump is worth it when you need ECC registered reliability for virtualization or database tasks and have matching slots ready.

Questions about this item

Does the 16GB (2 x 8GB) kit include anything other than the two memory sticks?

The package content lists only the two 240-pin DDR3L registered ECC modules; no extra cables, brackets or tools are supplied.

Should I choose this 1600 MHz CL11 1.35 V kit or a different speed for my ThinkServer RD340?

The server’s qualified memory runs at DDR3L 1600 (PC3L 12800) with CL11 timing and 1.35 V, so this matched kit is the correct version.

What does the registered ECC 2Rx4 design mean once the modules are installed in the RD340?

Registered buffering and ECC let each CPU address up to 192 GB across its six sockets while detecting and correcting single-bit errors in real time.
