4GB DDR3L Desktop Module

This 4GB DDR3L module upgrades desktop computers that accept 240-pin unbuffered memory. It operates at 1.35 volts and suits owners of systems specifying PC3L-12800 speed who need a direct replacement for Samsung M378B5173CB0-YK0, M378B5173DB0-YK0, M378B5173EB0-YK0 or M378B5173QH0-YK0 modules. Builders requiring ECC or registered DIMMs cannot use this part.

Sustained Load Behaviour

The module runs at a tested frequency of 1600 MHz under continuous workloads without raising voltage above the rated 1.35 V. Non-ECC unbuffered organisation means data moves directly to the memory controller, keeping latency stable during extended multitasking sessions. Quality-assurance testing verifies reliable operation at the specified DDR3L 1600 speed over time.

DDR3L 1.35V Voltage Key

The single specification that decides fitment is the 1.35 V DDR3L voltage; systems that only support standard 1.5 V DDR3 will not recognise this module. Matching the PC3L-12800 designation and 240-pin DIMM form factor to the motherboard memory list confirms compatibility. No other voltage or generation will work in its place.

Questions about this item

Will this 240-pin DDR3L module fit a desktop board that specifies 1.5 V DDR3?

The module runs at 1.35 V and is backward-compatible with 1.5 V slots; it will operate at the lower voltage automatically.

Can I mix this stick with existing 1600 MHz DDR3 memory?

Yes — matching the 1600 speed and unbuffered, non-ECC design allows it to run alongside identical-spec modules.

Is this the correct replacement for Samsung part M378B5173CB0-YK0?

The product is listed as a compatible replacement for that Samsung part number and the three related variants.
