Product identity and purpose

This 4 GB DDR3 1333 MHz registered ECC module is built for servers and workstations that require error-correcting registered memory. It uses a single 1Rx4 rank, runs at the standard 1.5 V DDR3 voltage, and fits 240-pin DIMM slots.

Who should consider this and who should not

It suits administrators replacing or expanding memory in systems qualified for PC3-10600 registered ECC DIMMs. It is not for desktops or laptops that accept only unbuffered non-ECC modules, nor for platforms limited to lower densities or different pin counts.

The specification that decides fit

The registered ECC design with 1Rx4 organisation and DDR3 1333 speed determines compatibility; the motherboard and CPU must support registered error-correcting DDR3 at this data rate.

Questions about this item

What comes in the box and is anything else needed to install it?

The box contains one 4GB DDR3 1333MHz ECC RDIMM module. No extra parts are required if your server has a free 240-pin DIMM slot and supports registered ECC memory.

Should I choose this 4GB 1Rx4 module or a different capacity for my server?

Choose this 4GB 1Rx4 module when your system needs a single registered ECC DIMM at 1333MHz. Add multiple identical modules to reach the total capacity your workload requires.

What does the PC3-10600 rating mean once the module is installed in a server?

PC3-10600 indicates a DDR3 1333MHz module with a peak data rate of 10600 MT/s, CL9 latency and 1.5V operation, giving your server registered ECC bandwidth at that speed.
