4GB DDR3L ECC UDIMM for IBM-Lenovo servers

This 4GB DDR3L 1333MHz ECC UDIMM module is built for IBM-Lenovo systems that require part numbers 03T8431, 47J0143, 49Y1404, or 49Y1422. It suits administrators expanding memory in compatible servers or workstations that support unbuffered ECC memory. The single 240-pin DIMM provides a direct replacement for qualified configurations.

Unbuffered ECC with low-voltage operation

The module operates at 1.35V as DDR3L, reducing power draw compared with standard DDR3 while maintaining 1333MHz speed and CL9 latency. Major-brand chips and 2Rx8 organisation deliver error-correcting code protection without registered buffering. This combination helps preserve data integrity in supported platforms that accept unbuffered ECC DIMMs.

240-pin DDR3L form factor decides fit

The 240-pin DDR3L DIMM form factor is the single specification that determines whether this module fits a given system. Only platforms designed for DDR3L 1333 unbuffered ECC UDIMMs can use it; systems requiring registered, fully buffered, or non-ECC memory will not accept this part.

Questions about this item

Will the ECC UDIMM chips or 240-pin contacts need periodic replacement?

The module uses major-brand chips on a standard 240-pin DIMM; no user-replaceable parts or scheduled maintenance are required.

What limits continuous throughput at DDR3L 1333 CL9?

Sustained bandwidth is capped by the 1333 MT/s data rate and CL9 latency of the PC3L-10600 specification.

How much heat and power does the 1.35 V DDR3L module draw under all-day load?

At 1.35 V the low-voltage DDR3L runs cooler and draws less power than standard 1.5 V DDR3 during extended operation.
