A-Tech 128GB (8x16GB) DDR5-5600 ECC UDIMM Server RAM Kit

SKU CH-PNXY-RXCR9

128 GB ECC UDIMM kit of eight 16 GB DDR5-5600 modules for servers and workstations

  • Total capacity128 GB (8 × 16 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor Brand Chipset
  • CAS latency40
  • Rated voltage1.1 V
  • Buffer typeUnbuffered

Capacity 128GB (8 x 16GB)

  • 128GB total capacity with eight 16GB modules
  • DDR5-5600 speed rated at PC5-44800 bandwidth
  • ECC unbuffered design detects and corrects data errors
  • Single-rank 1Rx8 layout for broad server compatibility
  • Standard 1.10V DDR5 voltage for efficient operation

Kit Configuration

This 128 GB kit contains eight 16 GB DDR5-5600 ECC UDIMM modules built for servers and workstations that accept unbuffered DDR5 memory. Each module runs at 1.1 V with CAS latency 40 and uses a 1Rx8 single-rank layout on 288-pin DIMMs.

Compatibility Guidance

The kit suits administrators upgrading DDR5 servers or workstations that require ECC unbuffered DIMMs and have eight available slots. It is not for desktop or laptop platforms, nor for systems that only accept registered or load-reduced memory.

Deciding Specification

The memory operates at DDR5-5600 (PC5-44800) with ECC unbuffered signalling, so the host platform must support that exact speed and UDIMM ECC type for the kit to function.

Questions about this item

Should I buy the 128GB kit or individual 16GB modules?

The kit provides eight matched 16GB modules totalling 128GB, ensuring identical timings and rank configuration across all slots for multi-channel server platforms.

What does the DDR5-5600 speed deliver in a live server?

The modules run at 5600 MT/s with CAS latency 40 at 1.1V, giving peak bandwidth of PC5-44800 while ECC corrects single-bit errors on the fly.

Will the PC5-44800 rating work on any DDR5 motherboard?

These are ECC unbuffered UDIMMs (EC4) with 288 pins; they only function in server or workstation boards that explicitly support DDR5 ECC UDIMM memory.
