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.

商品問答

What bandwidth does the DDR4 2666 PC4-21300 interface cap at in practice?

The PC4-21300 rating means the module transfers up to 21 300 MB/s at its tested 2 666 MHz speed.

Will the 288-pin DIMM fit my desktop motherboard slot?

Yes, the stick uses the standard 288-pin DDR4 DIMM form factor found on virtually all current desktop boards.

How do I install the module, and what step do people often miss?

Align the notch with the slot key, press straight down until both side clips snap shut — the click is the step many forget.
