4GB DDR3 1333 ECC RDIMM

This 4GB DDR3 1333 registered ECC module is built for HP server and workstation systems that require registered memory. It suits administrators maintaining legacy platforms where registered DIMMs are mandatory for stability.

Major brand chips with 240-pin DIMM form factor

The module uses major brand chips on a standard 240-pin DIMM PCB and operates at the standard 1.50V DDR3 voltage. Registered buffering reduces electrical load on the memory controller, supporting reliable operation in multi-DIMM configurations.

Verify DDR3 registered ECC support

Confirm your system accepts DDR3 registered ECC DIMMs before ordering, as unbuffered or non-ECC modules are not interchangeable. Check that a free 240-pin slot exists and that the platform supports 1Rx4 organisation at the required speed.

Questions about this item

Does the DDR3 1333 interface cap real-world throughput at PC3-10600?

Yes, the module runs at DDR3 1333 MHz with a PC3-10600 data-rate ceiling, so peak bandwidth is limited to that standard.

What physical slot and pin count does this 240-pin RDIMM require?

It fits a standard DDR3 DIMM socket with 240 pins; the registered design adds a buffer chip but does not change the slot keying.

How is the module installed and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the system detects the full 4 GB and ECC status in BIOS.
