A-Tech 64GB (2x32GB) DDR4 2933 ECC UDIMM 2Rx8 CL21 1.2V server RAM

SKU CH-X27K-EP4AN

A 64 GB dual-channel kit of DDR4 2933 ECC UDIMM modules with CL21 latency, dual-rank 2Rx8 organisation and standard 1.2 V operation for servers and workstations

  • CAS latencyCL21
  • Memory rank2Rx8
  • 64 GB kit expands server capacity for heavy workloads
  • Dual-rank 2Rx8 organisation increases memory density per channel
  • 2933 MHz DDR4 speed accelerates data throughput
  • ECC unbuffered design detects and corrects single-bit errors
  • 2 V standard voltage maintains efficient power draw

64 GB DDR4 2933 ECC UDIMM Kit

This A-Tech kit delivers 64 GB of DDR4 memory as two 32 GB ECC unbuffered DIMMs rated at 2933 MHz with CL21 latency. It is built for servers and workstations that require error-correcting code memory to maintain data integrity under continuous workloads.

For servers and workstations needing ECC UDIMM

The modules use a 2Rx8 dual-rank organisation at the standard 1.2 V DDR4 voltage and fit 288-pin DDR4 slots. Systems that accept only non-ECC memory, registered DIMMs, laptop SO-DIMMs or lower-density modules cannot use this kit.

ECC unbuffered UDIMM requirement

The single specification that determines compatibility is that the platform must support DDR4 ECC unbuffered UDIMM modules in a 288-pin form factor. Without that explicit support the memory will not function.

Questions about this item

Will the 288-pin DDR4 DIMMs fit my server's UDIMM slots?

Yes, these are standard 288-pin DDR4 UDIMMs designed for server and workstation boards that accept ECC unbuffered memory.

Do I need to install the two 32 GB modules in specific channel slots?

Install each module in the correct channel pair shown in your system manual; the common mistake is placing both sticks in the same channel instead of splitting them across channels.

Will the ECC function continue working if a single bit error occurs years later?

ECC UDIMM hardware corrects single-bit errors on the fly throughout the module's life; no user maintenance or replacement is required for that function.
