4GB DDR3 1333 ECC UDIMM Server Memory

This 4GB DDR3 1333 ECC UDIMM module is built as a compatible replacement for the Nanya NT4GC72B8PB0NF-CG part. It runs at 1333 MHz (PC3-10600) with CL9 latency and standard 1.5V operation. The 240-pin DIMM uses a 2Rx8 organisation and major-brand chips. It targets servers and workstations that require error-correcting unbuffered memory.

Who this suits and who should look elsewhere

This module fits systems that accept DDR3 1333 ECC UDIMM memory in a 240-pin slot. It is not for platforms that require registered or load-reduced DIMMs, nor for boards limited to non-ECC memory. Buyers needing capacities beyond 4GB per slot or speeds above 1333 MHz must select a different part.

The specification that decides fit

The decisive specification is the DDR3 1333 ECC UDIMM 240-pin form factor with 2Rx8 organisation at 1.5V. Only systems that explicitly support this exact combination will recognise and operate the module correctly.

Questions about this item

How do I install this 240-pin DDR3 ECC UDIMM, and what step do people often get wrong?

Align the notch on the module with the key in the 240-pin slot, press straight down until both retention clips click, and verify the system detects 4 GB at 1333 MHz; the common error is inserting the stick at an angle, which can bend pins or leave one clip unlatched.

What maintenance or replacement will this 4 GB 1.50 V DDR3 module need later?

No routine maintenance is required; if errors appear, run a memory diagnostic and replace the module if it fails — ECC corrects single-bit errors but cannot fix a failing chip.

What limit appears first when this 2Rx8 PC3-10600 stick runs under sustained load?

The 1333 MHz data rate and CL9 latency set the bandwidth ceiling; thermal throttling is rare at 1.50 V, so the speed rating is the first bottleneck you will hit.
