A-Tech 8GB DDR4 2666MHz PC4-21300 DIMM 1Rx8 desktop RAM

8GB DDR4 2666MHz Desktop DIMM

This 8GB DDR4 module runs at 2666MHz with a PC4-21300 rating. It uses the standard 1.20V voltage and an unbuffered non-ECC design. The 288-pin DIMM fits desktop motherboards that support DDR4 memory.

Suits standard desktop upgrades.

Builders replacing a Hynix HMA81GU6CJR8N-VK, HMA81GU6DJR8N-VK or HMA81GU6JJR8N-VK module can use this as a direct replacement. It works with AMD and Intel platforms that accept unbuffered non-ECC DDR4. Systems requiring ECC error correction or registered buffered memory cannot use this module.

1Rx8 single-rank organisation

The memory is organised as 1Rx8, meaning a single rank of eight-bit wide chips. This rank structure affects how the memory controller addresses the module and can influence maximum capacity per channel on some platforms. Check your motherboard documentation to confirm 1Rx8 support before purchasing.
