OWC 4GB DDR3 1600 PC3-12800 CL11 2Rx8 240-pin 1.5V Non-ECC UDIMM desktop RAM

4GB DDR3 1600 UDIMM for desktop upgrades

This OWC module provides four gigabytes of DDR3 memory rated at 1600 MT/s with a CAS latency of 11. It uses the standard 240-pin UDIMM form factor and operates at 1.5 volts without ECC or registered buffering. The stick is intended for desktop and workstation systems that accept PC3-12800 memory.

Thermals and power in daily use

Running at the JEDEC-standard 1.5 volts keeps power draw low and heat output modest for a DDR3 DIMM. No heat spreader is fitted, so the bare PCB relies on normal case airflow to stay within safe temperatures. The module produces no audible noise because it has no moving parts.

Build integration and slot considerations

The 240-pin keying matches desktop DDR3 slots, and the unbuffered design works with consumer motherboards that support non-ECC memory. A single 4GB rank leaves additional DIMM slots free for further expansion up to the platform limit. JEDEC and RoHS compliance ensures the module meets industry specifications for a warranty-safe upgrade.
