64GB DDR4 3200 Kit for Desktop Upgrades

This A-Tech kit contains two 32GB DDR4 modules running at 3200MHz with CL22 timing. The dual-rank DIMMs operate at the standard 1.2V and use the 288-pin form factor for desktop motherboards. It is sold as a matched dual-channel pair for a total capacity of 64GB.

Suits standard desktop DDR4 systems needing high

The kit works with motherboards that accept 32GB per slot and support non-ECC unbuffered DDR4. Systems that require ECC, registered memory, or a different DDR generation will not be compatible. Always check the board specifications before ordering.

32GB per module density decides fit

Each stick is a single 32GB dual-rank module, so the motherboard must support that density in each slot. If the board limits capacity per slot to a lower figure, the memory will not function. Verify the maximum supported module size for your specific platform.

Questions about this item

Will this kit fit a motherboard that takes 288-pin DDR4 DIMMs?

Yes. Each module is a standard 288-pin DDR4 UDIMM, so it installs in any desktop board with DDR4 DIMM slots.

My board only supports up to 32 GB per slot — is that a problem?

No. Each stick is 32 GB, matching that per-slot limit, and the two-module kit gives 64 GB total when both slots are filled.

Do I need to enable anything in BIOS to run at the rated 3200 MHz?

The modules are rated for 3200 MHz at CL22 and 1.20 V. Most boards will pick that up automatically, but if XMP or DOCP is available, enabling it guarantees the rated speed.
