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.

Perguntas sobre este artigo

How do I install the 240-pin DDR3 DIMM and what step is often missed?

Align the notch on the module with the key in the slot, press down firmly until both side clips snap shut, then verify the system reports the full 4GB at 1600MHz in BIOS.

What maintenance or replacement will this 1.5V non-ECC UDIMM need later?

No scheduled maintenance is required; if errors appear, run a memory test and replace the module if it fails, otherwise it runs for the system's life.

What limit appears first when the CL11 2Rx8 module runs under sustained load?

The DDR3 1600 bandwidth ceiling of PC3-12800 is reached before thermal throttling, since the module has no heat spreader and operates at standard JEDEC voltage.
