  • 64GB total capacity from four 16GB modules for heavy multitasking
  • DDR5 5200MHz speed with PC5-41600 bandwidth for fast data throughput
  • CL42 CAS latency at standard 1.1V DDR5 voltage for efficient operation
  • 288-pin unbuffered DIMM form factor fits compatible desktop motherboards
  • Major-brand DRAM IC chips tested for reliable long-term performance

Kit configuration

This A-Tech kit provides 64GB of DDR5 desktop memory in a matched set of four 16GB modules. It is built for systems that support DDR5 5200 DIMMs and can run a quad-channel layout.

Fit and alternatives

The kit suits desktops accepting non-ECC unbuffered DDR5 at the standard 1.1V voltage. Builds needing ECC or registered DIMMs, or boards with fewer than four DIMM slots, should choose a different configuration.

Deciding specification

The tested speed is DDR5 5200 with a CAS latency of CL42, delivering PC5-41600 bandwidth. Verify that your motherboard and CPU officially support this frequency and timing before purchase.

Questions about this item

Is this 288-pin DDR5 kit compatible with a motherboard that has only four DIMM slots?

The kit contains four 16 GB modules, so it will fill all four slots on a standard four-slot board; verify your motherboard supports DDR5-5200 and quad-channel operation before installing.

Does the memory run at the standard 1.1 V without manual BIOS changes?

Yes, the modules are rated at 1.10 V, which is the DDR5 default voltage, so they should operate at 5200 MHz CL42 on any compatible platform without voltage adjustments.

Can I use this non-ECC unbuffered kit in a workstation board that requires registered ECC DIMMs?

No, this kit is non-ECC and unbuffered; it is intended for consumer desktop platforms and will not function in systems that mandate registered ECC memory.
