Capacity 4GB

Speed DDR3 1600 (PC3 12800)

  • ECC protects data integrity in servers with single-bit error correction
  • 1600 MHz DDR3 speed accelerates workloads with PC3-12800 bandwidth
  • 5 V standard voltage ensures broad DDR3 platform compatibility
  • Single-rank 1Rx8 layout simplifies memory-channel population
  • 240-pin UDIMM form factor fits DDR3 server and workstation slots

Server memory upgrade for DDR3 ECC platforms

This 4 GB DDR3 1600 MHz module adds capacity to servers and workstations that require ECC unbuffered DIMMs. The single-rank x8 organisation works with systems qualified for PC3-12800E memory. It is not compatible with standard desktop or laptop computers.

Standard voltage operation with ECC integrity

The module runs at the JEDEC-standard 1.5 V, drawing typical power for DDR3 1600 MHz ECC UDIMMs. Error-correcting code protects data integrity during continuous workloads without generating additional heat or acoustic load beyond the platform's normal memory subsystem.

Ready-to-install single module

The 240-pin DIMM arrives tested and qualified for immediate installation in supported DDR3 ECC unbuffered slots. No extra cables, brackets or configuration utilities are included; the performance gain comes from the added capacity and ECC protection alone.

Questions about this item

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

Align the notch on the module with the slot key, press firmly until both side clips click shut, then verify the system detects the full 4 GB capacity in BIOS or the OS memory report.

What maintenance or replacement will this module need later?

No routine maintenance is required; if errors appear, run a memory diagnostic and replace the stick if it fails, otherwise it runs for the life of the server.

What limit appears first under sustained load with this CL11 1.5 V module?

The CL11 latency at 1600 MHz sets the throughput ceiling, so sustained bandwidth maxes out at the PC3-12800 rate before voltage or thermal limits are reached.
