64GB Quad Channel DDR4 Kit

This A-Tech kit provides 64GB of DDR4 memory across four 16GB unbuffered DIMMs. It runs at 2133MHz with a tested timing of CL15 and standard 1.2V operation. The modules use major brand chips and are validated for AMD and Intel desktop platforms.

Desktop builds needing 64GB at standard JEDEC speed

The 288-pin non-ECC design suits mainstream desktop motherboards that support quad channel DDR4 at 2133MHz. Systems requiring ECC, registered DIMMs, or higher factory clock speeds should select a different kit.

CL15 timing at 2133MHz

The tested latency of 15 cycles at 2133MHz determines responsiveness in latency sensitive workloads. Verify that your motherboard and CPU memory controller support this speed and timing before purchase.

Questions about this item

Will the 288-pin DIMM modules fit my desktop motherboard?

The kit uses standard 288-pin DDR4 DIMMs that install in any desktop board with DDR4 slots.

What is the correct way to seat all four 16GB sticks, and what step do people miss?

Open the slot clips, align the notch on each module, press down firmly until both clips click shut, then verify the BIOS shows 64GB at 2133MHz.

Do these non-ECC unbuffered modules need any maintenance or replacement over time?

No routine maintenance is required; the modules run at 1.2V standard voltage and are covered by a lifetime warranty if a fault ever develops.
