Kit contents and fit

This 16 GB kit contains two 8 GB DDR3 ECC unregistered DIMMs rated at 1600 MHz CL11. It is built for the Lenovo ThinkServer TS140U and matches the 240-pin DDR3 slots in that chassis.

ECC and voltage notes

The modules run at 1.5 V and provide error-correcting code without registration, a combination the TS140U expects. The supplier notes the sticks may ship as 1.35 V DDR3L parts depending on inventory, but both voltages are accepted by the platform.

What to verify first

Confirm your TS140U has free 240-pin DDR3 slots and that the current BIOS recognises ECC unregistered memory. The server supports a maximum of 32 GB across four sockets, so this kit fills half that capacity. Buyers needing registered DIMMs or a different DDR generation cannot use this kit.

Questions about this item

Does the 2Rx8 ECC unregistered DIMM design require any periodic maintenance or replacement?

No, the kit has no moving parts or consumable components and carries a limited lifetime warranty from Computer Memory Solutions.

Will the four-slot 32 GB maximum on the ThinkServer TS140 be reached before CPU or thermal limits appear?

Yes, this 16 GB kit occupies two of the four slots, leaving room for another 16 GB before the platform's 32 GB ceiling is hit.

How much heat and power do the 1.5 V DDR3 and 1.35 V DDR3L modules produce during continuous operation?

Both voltages are standard low-power DDR3 levels; the modules run cool enough for 24/7 server use without active cooling on the DIMMs themselves.
