OWC

OWC 4GB DDR3 1600 CL11 1.5V UDIMM desktop RAM

SKU CH-7J7E-15MCQ

A 4 GB DDR3 desktop module running at 1600 MHz with CL11 latency and 1.5 V operation

  • Capacity4GB
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.5V
  • ECCNo
  • Buffered/RegisteredUnbuffered

Capacity 4GB

  • 4GB capacity adds room for more open apps and files
  • DDR3 1600 speed at CL11 latency keeps data flowing to the processor
  • 5V JEDEC-standard voltage works with stock desktop motherboards
  • Single 240-pin unbuffered module installs in a free DIMM slot
  • ROHS-compliant build meets industry environmental and safety specs

Single 4GB DDR3-1600 UDIMM module

This OWC module is a single 4GB DDR3 UDIMM rated at 1600MHz with CL11 latency and 1.5V operation. It uses a 240-pin 1Rx8 unbuffered non-ECC design and carries JEDEC and RoHS compliance. The black PCB has no heat spreader or LEDs. It is built for desktop and workstation memory slots.

Suits DDR3 desktop or workstation upgrades

This module fits systems that accept DDR3 UDIMMs at 1600MHz and 1.5V without ECC or registered buffering. It works for straightforward capacity increases in compatible desktops and workstations. Systems requiring ECC, registered DIMMs, or speeds above 1600MHz need a different module. Laptops and small-form-factor boards using SO-DIMMs cannot use this 240-pin part.

240-pin DDR3 UDIMM form factor

The 240-pin DDR3 UDIMM form factor is the single specification that decides fit. If the motherboard takes 240-pin DDR3 unbuffered non-ECC DIMMs at 1.5V this module will install; otherwise it will not seat or function.

Questions about this item

Does the OWC 4GB DDR3 1600 module ship as a single stick or a kit, and is any extra hardware needed?

The package contains one 4GB DDR3 1600 CL11 1.5V UDIMM module; no additional brackets, cables or tools are required for installation.

How do I decide between this 4GB CL11 stick and a higher-capacity or lower-latency DDR3 option?

Choose this 4GB CL11 module when your board has a free 240-pin slot and you need a straightforward capacity boost; select a larger or tighter-timing kit only if your workload and motherboard specifications justify the extra cost.

What does the 1600 MHz rating actually deliver once the DIMM is seated in a desktop?

The module runs at DDR3 1600 (PC3-12800) with CL11 timing at the standard 1.5V, giving the rated bandwidth and latency provided your motherboard supports that speed and the BIOS is set to the correct profile.
