System-Specific DDR3 ECC Kit

This 8 GB kit contains two 4 GB unregistered DIMMs built for the Lenovo ThinkServer TS440. Each module runs at DDR3 1600 (PC3-12800) with CL11 timings at 1.5 V and includes ECC error correction for data integrity in server workloads.

Suits TS440 owners needing ECC memory

Designed for administrators upgrading a ThinkServer TS440 that requires unbuffered ECC DIMMs. Not suitable for systems that demand registered or load-reduced modules, nor for platforms limited to non-ECC consumer memory.

Check your TS440 configuration first

Verify the server has free 240-pin DIMM slots and that the installed processor supports unregistered ECC memory at 1600 MHz. The TS440 accepts up to 32 GB across four sockets, so confirm the current population before adding this two-stick kit.

Questions about this item

Does the Lenovo ThinkServer TS440 need to have ECC memory support enabled in BIOS for these 1600 MHz DDR3 modules to function?

The TS440 supports ECC unregistered DIMMs natively; the 2Rx8 modules operate at 1.5 V with CL11 timing once installed in any of the four DIMM sockets.

Can I keep my existing 4 GB DDR3 sticks and add this 2 x 4 GB kit to reach 32 GB total in the TS440?

Yes, the server has four sockets and a 32 GB maximum; mixing ranks is supported so the 2Rx8 kit works alongside single-rank modules.

How do I confirm the kit is running at 1600 MHz with ECC active after installation?

Check the BIOS memory information screen — it will show 1600 MT/s, ECC enabled, and 8 GB total across the two new DIMMs.
