Four green DDR4 ECC UDIMM sticks in a kit

A-Tech

A-Tech 32GB (4x8GB) DDR4 2400 MHz ECC UDIMM 1Rx8 CL17 Server RAM

SKU CH-T40Q-VDDXZ

A 32 GB kit of four 8 GB DDR4 ECC unbuffered DIMMs running at 2400 MHz with CL17 latency for servers and workstations

  • CAS latencyCL17
  • Memory rank1Rx8
  • 32 GB total capacity in a 4-module kit
  • DDR4 2400 MHz speed for fast data throughput
  • ECC UDIMM with single-rank 1Rx8 organisation
  • CL17 latency at standard 1.2 V operation
  • 288-pin DIMM form factor for server and workstation slots

Server-grade DDR4 kit

This 32 GB kit contains four 8 GB DDR4 ECC unbuffered DIMMs rated at 2400 MHz with CL17 latency. It is built for servers and workstations that require error-correcting memory and will not function in standard desktop or laptop platforms.

288-pin single-rank modules

Each module uses a 1Rx8 organisation and operates at the standard 1.2 V DDR4 voltage. The unbuffered design connects directly to the memory controller, so the motherboard must support ECC UDIMM population rules and channel guidelines for stable operation.

Replaces non-ECC or lower-capacity DDR4

The upgrade adds error correction and doubles typical entry-level server memory, improving data integrity for virtualisation, databases and long-running workloads. The jump is worthwhile when your workload exceeds current capacity or when the platform mandates ECC for qualification.

Questions about this item

What DDR4 standard and speed does this 32 GB kit use, and what peak transfer rate does PC4-19200 represent?

The kit runs at DDR4 2400 MHz under the PC4-19200 designation.

What physical slot and pin count do these four 8 GB modules require?

Each module is a 288-pin UDIMM that fits standard DDR4 DIMM sockets.

How do I install the four sticks correctly, and what channel mistake should I avoid?

Populate matching-colour slots per the motherboard manual to activate quad-channel mode; skipping a slot breaks the channel.
