Server memory upgrade

This 4GB DDR3L ECC UDIMM module is built for servers and workstations that require error-correcting unbuffered memory. It operates at 1333 MHz with a CAS latency of CL9 and runs at 1.35V low voltage. The dual-rank 2Rx8 organisation uses major-brand chips on a 240-pin DIMM form factor.

Replaces non-ECC or slower DDR3

The module upgrades systems currently running non-ECC memory or lower-speed DDR3 by adding error correction and 1333 MHz bandwidth. The jump is worth it when your workload demands data integrity and the motherboard supports DDR3L ECC unbuffered DIMMs. It is not for desktop or laptop computers that cannot accept server-class ECC UDIMMs.

Sustained load behaviour

Under continuous operation the low 1.35V voltage reduces thermal output compared to standard 1.5V DDR3 while maintaining CL9 timing stability. The ECC circuitry corrects single-bit errors in real time without buffering delays, keeping throughput consistent during extended workloads. Major-brand chipsets ensure reliable signal integrity across all ranks during prolonged use.

Questions about this item

Does this 240-pin DDR3L module fit a standard server DIMM slot?

Yes, the 240-pin DDR3L DIMM matches the standard unbuffered ECC slot used in compatible DDR3 servers and workstations.

What is the correct way to seat this dual-rank ECC UDIMM?

Align the notch with the slot key, press firmly until both retention clips click, and follow the system manual for channel population order.

Will this 1.35 V module need any voltage adjustment later?

It operates at 1.35 V or 1.5 V automatically; no manual adjustment is required during its service life.
