64GB Quad-Channel DDR4 Kit

This A-Tech kit provides 64GB of desktop memory across four 16GB modules. It is built for DDR4 systems that accept 288-pin UDIMMs. The quad-channel configuration suits workstations and high-capacity desktops needing large memory pools.

DDR4 2666 Standard Limits

The modules run at 2666MHz with a tested CAS latency of 19 at the standard DDR4 voltage of 1.2V. As non-ECC unbuffered DIMMs they follow the PC4-21300 specification and will operate at the highest common speed supported by the motherboard and CPU memory controller.

Pre-Installation Checks

Verify that your desktop motherboard has four available 288-pin DDR4 slots and supports 16GB per slot. Confirm the platform accepts non-ECC unbuffered memory at 1.2V. Check the qualified vendor list or manual for 2666MHz compatibility before ordering.

Questions about this item

Will this kit work in a motherboard with only two DIMM slots?

The kit contains four 16 GB modules and requires four slots; a two-slot board cannot use the full 64 GB capacity.

Does the memory need a voltage higher than the standard 1.2 V?

No, the modules run at the standard 1.2 V DDR4 voltage, so no extra voltage headroom is required.

Is this RAM compatible with a system that only supports ECC memory?

The modules are non-ECC unbuffered DIMMs, so they will not work in a platform that requires ECC memory.
