8GB DDR3 Module for ThinkStation P300

This 8GB DDR3 1600 CL11 UDIMM is built specifically for the Lenovo ThinkStation P300 workstation. It installs as a single 240-pin DIMM to increase system memory capacity. The module follows JEDEC-standard PC3-12800 timing at 1.5V. Buyers who need ECC error correction or registered buffering cannot use this non-ECC unbuffered part.

Thermals and Power at Standard Speed

The module operates at the standard 1.5V DDR3 voltage without a heat spreader. Power draw stays within JEDEC limits for PC3-12800 during typical workloads. Passive cooling relies on chassis airflow inside the ThinkStation P300. No fan or active cooling is required or included with this memory upgrade.

Compliance and Installation Support

JEDEC and RoHS compliance make the upgrade warranty-safe for the supported workstation. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme. An online installation video guides the DIY fitting process. No extra software, cables or mounting hardware are bundled with the memory module.

Questions about this item

How is the 240-pin DDR3 module installed in the ThinkStation P300, and what step is often missed?

Power off the workstation, open the case, align the notch on the 240-pin DDR3 module with the slot key, press firmly until both retention clips click shut, then verify the 8 GB appears in BIOS before closing the chassis.

What maintenance or replacement will the 8 GB DDR3 1600 CL11 module need later?

The unbuffered non-ECC UDIMM has no heat spreader and no moving parts, so only occasional dust removal from the slot contacts is needed; the module itself requires no scheduled replacement.

What limit appears first when the 2Rx8 1.5 V DIMM runs sustained workloads?

The CL11 latency at DDR3 1600 (PC3-12800) sets the bandwidth ceiling, so memory throughput saturates before the 1.5 V voltage or thermal envelope becomes a constraint.
