Capacity and compatibility

This 64 GB kit contains four 16 GB DDR4 SODIMM modules rated at 2133 MHz with CL15 timings. It is built specifically for the Lenovo ThinkPad P50 and uses the 260-pin SO-DIMM form factor. The unbuffered, non-ECC design matches the notebook's memory controller requirements. Voltage is set at 1.2 V for standard mobile operation.

Sustained workload behaviour

The CL15 15-15-15 timing set delivers consistent latency during extended multitasking or rendering sessions. Dual-rank 2Rx8 organisation helps maintain bandwidth when all four slots are populated. Because the modules have no heat spreaders, they rely on the chassis airflow of the ThinkPad P50 to stay within thermal limits under continuous load.

Installation notes

Each stick inserts into the standard 260-pin SODIMM slots accessible under the service panel. Align the notch with the key and press firmly until the side clips engage. The most common issue is incomplete seating, which causes the system to recognise less than the full 64 GB or fail to boot. Verify the total in BIOS after installation.

商品問答

How much power does the 1.2V DDR4 kit draw when the ThinkPad P50 runs all day?

Each 16 GB module operates at 1.2 V, the standard DDR4 voltage, so total draw stays within the laptop's normal memory power budget during sustained workloads.

What must the ThinkPad P50 already have for this 4 x 16 GB kit to work?

The notebook needs four free 260-pin SODIMM slots and a BIOS that supports 64 GB of unbuffered non-ECC DDR4 2133 memory.

Will the CL15 2133 MHz modules run correctly alongside any original 2133 MHz sticks I keep in the P50?

Yes, matching speed and CAS latency lets the new 2Rx8 modules operate in sync with existing DDR4 2133 CL15 SODIMMs without timing conflicts.
