Product identity

This OWC 4GB DDR3L module is a 240-pin non-ECC unbuffered DIMM built to JEDEC PC3L-12800 CL11 1.35 V specifications. It is made for HP ProDesk 400 G2.5 SFF systems and installs as a single 1Rx8 stick to raise total memory quickly.

Who it suits

Offices and home users who need a straightforward capacity increase for everyday multitasking, web browsing and office applications on the named ProDesk will find it a direct fit. Builders who require ECC protection, registered buffering, higher speeds, larger single-module capacities or a different form factor must choose another part.

Deciding specification

The module runs at DDR3L 1600 (PC3L-12800) with CL11 latency at 1.35 V; if the target system demands a different voltage, speed, pin count or memory generation this DIMM will not work.

Questions about this item

Will the 240-pin DDR3L DIMM need any periodic maintenance or replacement after installation?

The module has no moving parts and no heat spreader, so it requires no scheduled maintenance; it is designed to remain in place for the life of the HP ProDesk 400 G2.5 SFF.

What limit appears first when the 4GB DDR3L 1600 module runs under sustained load?

The practical limit is the 4GB capacity itself — once the operating system exhausts that space it must swap to storage, which is the first bottleneck during prolonged heavy use.

How much heat or noise does the 1.35V unbuffered DIMM produce when the system runs all day?

The low-voltage 1.35V DDR3L module generates minimal heat and has no fan, so it adds no audible noise and only a small amount of warmth to the chassis during continuous operation.
