Lenovo IdeaCentre DDR4 upgrade

This 8 GB DDR4 module is built for the Lenovo IdeaCentre 300s, Ideacentre 720-18IKL and Kai Tian M4650. It arrives as a single unbuffered DIMM using major-brand chips and runs at the standard 1.2 V. Buyers needing ECC protection or registered memory should look elsewhere.

Steady 2400 MHz operation

Rated at DDR4-2400 with CL17 timings of 17-17-17, the stick maintains its rated frequency during extended workloads without relying on short bursts. The 2Rx8 organisation helps keep bandwidth consistent across the two available slots. No heat spreader is fitted, so case airflow handles thermal management.

Two-slot 32 GB ceiling

The platform caps total memory at 32 GB across two sockets, so this 8 GB kit fills one slot and leaves room for a matching module. Installing a single stick runs in single-channel mode; adding a second identical unit enables dual-channel throughput. Systems already populated to the limit cannot accept this part.

Questions about this item

How much power does the 1.2V DDR4 module draw when the Lenovo IdeaCentre 300s runs all day?

The module operates at 1.2V, the standard DDR4 voltage, so power draw stays low during continuous operation.

What must the Lenovo IdeaCentre 720-18IKL already have for this 288-pin DIMM to work?

The desktop needs a free 288-pin DDR4 slot and a BIOS that supports 2400 MHz non-ECC memory.

Will this 2Rx8 stick run at 2400 MHz alongside the original DDR4 memory in a Kai Tian M4650?

Yes, it matches the 2400 MHz speed and 1.2V voltage, so it will sync with existing DDR4 modules at that frequency.
