System-specific DDR3 kit for Lenovo ThinkStation

This 16 GB kit contains two 8 GB DDR3-1600 unbuffered DIMMs built to CL11 timings at 1.5 V. It is designed for the ThinkStation P300 Tower and SFF workstations listed in the compatible manufacturing numbers.

Sustained-load behaviour with standard DDR3 timings

The modules run at 1600 MHz with 11-11-11 latency and operate at the standard 1.5 V DDR3 voltage. Unbuffered non-ECC construction means the memory controller handles refresh directly, giving predictable throughput during long rendering or compute sessions.

Pre-order checklist for your ThinkStation P300

Verify the system uses a desktop processor if you need the 32 GB non-ECC UDIMM limit, or a Xeon processor for the 32 GB ECC UDIMM limit. Confirm the board has four DIMM sockets free for this 2 x 8 GB kit and that existing memory matches DDR3-1600 non-ECC unbuffered specifications.

Questions about this item

How much heat and power will the 1.5 V DDR3-1600 kit draw when the ThinkStation P300 runs all day?

Each module runs at 1.5 V without a heat spreader; typical DDR3-1600 power is low enough that the P300's standard tower or SFF airflow handles continuous load without extra cooling.

What must the workstation already have so these two 240-pin DIMMs install and boot?

The P300 needs a desktop or Xeon processor, four free DDR3 UDIMM slots and a BIOS that accepts non-ECC 1600 MHz memory up to the 32 GB non-ECC limit.

Will the CL11 2Rx8 sticks work beside any original Lenovo DDR3 modules I keep in the other slots?

Yes — they are unbuffered non-ECC DDR3-1600 1.5 V DIMMs, matching the P300's supported spec, so mixing with identical-speed Lenovo modules is supported up to the 32 GB total.
