8GB DDR3 1600 ECC UDIMM for IBM-Lenovo Servers

This 8GB module provides ECC error correction on an unbuffered DDR3 1600 platform. It suits administrators upgrading compatible IBM-Lenovo systems where registered memory is not required. The 2Rx8 organisation delivers standard density for mainstream server workloads.

Sustained load behaviour with CL11 1.50V operation

At CL11 latency and standard 1.50V the module maintains consistent throughput during extended compute tasks. ECC circuitry detects and corrects single-bit errors without halting the system. Unbuffered signalling keeps latency low for memory-bound applications running continuously.

240-pin DIMM build using major brand chips

The 240-pin DIMM fits standard DDR3 server slots and uses major brand components selected for reliability. ECC UDIMM pin-out matches the listed IBM-Lenovo part numbers for direct replacement. Buyers needing registered DIMMs or larger capacities must select different modules.

Questions about this item

Does the 1.5 V DDR3 1600 module run hotter or draw more power than lower-voltage DDR3 when the server runs all day?

It operates at the standard 1.5 V DDR3 voltage, so heat and power draw match typical DDR3 1600 ECC UDIMMs under sustained load.

What motherboard slot and memory controller features must my system provide for this 240-pin ECC UDIMM to function?

The board needs a DDR3 240-pin DIMM slot with an integrated memory controller that supports unbuffered ECC at 1600 MHz.

Can I mix this CL11 1600 MHz stick with slower DDR3 ECC UDIMMs already in the server?

Yes, the module will down-clock to the speed of the slowest installed DIMM while keeping ECC active across all channels.
