A-Tech 128GB (4x32GB) DDR5 4800 ECC UDIMM 2Rx8 CL40 1.10V server RAM

SKU CH-Y43Y-RT1QV

128 GB quad-channel DDR5 ECC UDIMM kit with four 32 GB dual-rank modules at 4800 MT/s CL40 1.10 V

  • Capacity128GB (4 x 32GB)
  • Type288-Pin DDR5 SDRAM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS LatencyCL40
  • Voltage1.10V
  • ECCYes

Capacity 128GB (4 x 32GB)

  • ECC protection prevents data corruption in critical workloads
  • 128GB quad-channel kit with four 32GB modules
  • DDR5 4800 speed delivers high memory bandwidth
  • 10V standard voltage reduces power consumption
  • 2Rx8 dual-rank organisation increases memory density

Kit Configuration

This A-Tech kit provides 128GB of DDR5 server memory across four 32GB unbuffered ECC UDIMMs. Each module runs at 4800 MHz with CL40 latency at the standard 1.10V. The dual-rank 2Rx8 organisation and 288-pin form factor are built for quad-channel server and workstation platforms.

Target Systems

Suited for administrators upgrading compatible DDR5 servers or workstations that specifically require ECC unbuffered DIMMs. Not intended for desktop or laptop computers, nor for systems that need registered or load-reduced memory. Buyers who need a different capacity, speed, or rank configuration should verify their platform documentation before purchasing.

Deciding Specification

The modules are ECC unbuffered DDR5 UDIMMs, not registered or LRDIMMs, so they will only work in platforms that explicitly support this memory type. Confirm that your server or workstation accepts 2Rx8 EC4 UDIMMs at 4800 MHz before ordering.

Preguntas sobre este artículo

How do I install this 288-pin DDR5 UDIMM kit in a quad-channel server, and which step is most often missed?

Insert each 32 GB module into the correct colour-coded slot per channel, press down until both retention clips click, then verify in BIOS that all 128 GB appear at 4800 MHz — the step most often missed is populating all four channels in the motherboard's prescribed order.

What maintenance or replacement will this ECC UDIMM kit need over its service life?

No scheduled maintenance is required; the modules have no heat spreaders and run at standard 1.10 V, so only a failed DIMM would need replacement, which is covered by the manufacturer's lifetime warranty.

What limit appears first when this 2Rx8 DDR5 4800 kit runs sustained workloads?

The CAS latency of CL40 at 4800 MHz sets the timing ceiling; under continuous heavy load the memory controller will hit this latency bound before voltage or thermal limits become a factor.
