64GB DDR4-2666 Kit for Desktop Upgrades

This 2x32GB kit provides 64GB of total capacity using two 288-pin DIMM modules. Each module operates at 2666MHz with a CAS latency of 19 and a voltage of 1.2V. The memory is unbuffered, non-ECC and organised as 2Rx8 for broad desktop compatibility.

Suits standard desktop DIMM slots.

Builders adding memory to a desktop with four 288-pin slots will find this kit matches the DDR4 form factor and speed. Systems that require ECC, registered modules or SO-DIMM modules cannot use these DIMMs. Buyers needing ECC error correction or registered buffering should look at a different product type.

Dual-rank 2Rx8 organisation on each 32GB module

Each 32GB module uses a 2Rx8 configuration, which determines how the memory controller addresses the chips. If your platform requires single-rank modules or a different rank structure, this kit will not be compatible. Verify the motherboard documentation for supported rank configurations before purchase.

商品問答

Does this DDR4-2666 kit run at the full 2666 MHz on my motherboard, or is it capped by the CPU's memory controller?

The modules are rated for DDR4-2666 (PC4-21300), but the system will run all memory at the slowest speed of the installed modules or the CPU's maximum supported frequency.

Will these 288-pin DIMMs physically fit in my desktop's memory slots?

Yes, they use the standard 288-pin DDR4 DIMM form factor for desktop systems; ensure your motherboard has DDR4 slots and enough clearance around the socket.

How do I install the two 32 GB sticks correctly for dual-channel operation?

Insert both modules into the matched pair slots — typically the same-coloured sockets — so the memory controller activates dual-channel mode; a common mistake is populating adjacent slots instead of the paired ones.
