OWC 4GB DDR3 for ThinkStation P300

This module is a 4GB DDR3 1600 CL11 UDIMM built to JEDEC standards for the Lenovo ThinkStation P300. It runs at 1.5V and uses a 240-pin unbuffered non-ECC design. The single rank 1Rx8 layout fits the workstation's memory slots directly.

Suits P300 owners adding 4GB DDR3.

It suits ThinkStation P300 owners who need a straightforward 4GB DDR3 upgrade. Builders working with any other desktop or server platform cannot use this module because the compatibility is limited to the P300. Systems that require ECC or registered memory should look elsewhere.

240-pin DDR3 1600 CL11 1.5V non-ECC UDIMM

The deciding specification is the 240-pin DDR3 1600 CL11 1.5V non-ECC UDIMM form factor. Only motherboards that accept this exact DDR3 UDIMM type will recognise the module. Verify the slot and voltage before ordering.
