4GB DDR3 1333 ECC UDIMM for HP Servers

This 4GB DDR3 1333 (PC3-10600) module is an unbuffered ECC UDIMM built with a 2Rx8 organisation. It runs at the standard 1.5V and carries a CL9 latency rating. The 240-pin DIMM is designed as a direct replacement for HP part numbers 500210-071 and 500210-571 in compatible server and workstation platforms.

Sustained load behaviour with ECC protection

Error-correcting code detects and corrects single-bit errors during continuous operation, helping to prevent data corruption under heavy, long-running workloads. Unbuffered architecture keeps latency low for each access while the 2Rx8 rank layout allows the memory controller to interleave across ranks. The 1.5V supply remains within standard DDR3 limits, so thermal output stays consistent during extended use.

Verify platform support before ordering

Confirm that your system accepts DDR3 1333 ECC UDIMM modules in a 240-pin slot and that the firmware enables ECC on unbuffered DIMMs. Check the maximum supported capacity per slot and the total number of populated channels allowed by the memory controller. Ensure the motherboard or server board is qualified for 2Rx8 rank configurations at this speed and voltage.

Questions about this item

Does this 1.50 V DDR3 1333 module draw much power or generate extra heat when the server runs all day?

It operates at standard 1.50 V DDR3 voltage, so power draw and heat output are typical for a 4 GB DDR3 1333 ECC UDIMM under continuous load.

What must the motherboard provide for this 240-pin DDR3 ECC UDIMM to work?

A DDR3 DIMM slot that accepts unbuffered ECC modules at 1.5 V and supports 2Rx8 organisation.

Will this DDR3 1333 CL9 stick work in a system that currently runs slower DDR3 modules?

The module runs at DDR3 1333 (PC3-10600) CL9; the motherboard will set the common speed for all installed DIMMs.
