Capacity and kit layout
This kit provides 64GB of DDR4 memory in a matched pair of two 32GB modules. It is built for owners of the listed ASUS Prime Z390 and Z490 motherboards who need the full 64GB capacity in a dual-channel configuration. The unbuffered, non-ECC design suits standard desktop workloads and gaming rigs.
Physical build and daily use
Each stick is a 288-pin DIMM without a heat spreader, so it fits into tight slots and under large CPU coolers without clearance issues. The modules operate at the standard 1.2V, keeping power draw low and installation straightforward on the four supported motherboard sockets. Mixing with other kits will force all memory to run at the slowest installed speed.
Deciding specification
The rated speed is DDR4 2666 (PC4 21300) with CL19 19-19-19 timings at 1.2V. If your CPU or motherboard cannot run at 2666MT/s, the kit will downclock automatically, but it will not reach higher data rates. Buyers who need faster JEDEC speeds or lower latencies should look elsewhere.

이 상품에 대한 질문
What speed does the DDR4 2666MHz interface actually deliver in practice?
The modules run at DDR4 2666 (PC4 21300) with CL19 19-19-19 timings at 1.2V; all installed memory will operate at the slowest module or CPU capability.
What physical clearance and slot layout does this 288-pin DIMM kit require?
Two unbuffered 288-pin DIMMs, each 32GB 2Rx8 without heat spreaders, fit the four slots on the listed ASUS PRIME Z390 and Z490 boards.
How do I install the pair correctly and which step is commonly missed?
Insert both sticks into matching-coloured slots for dual-channel operation; a 64-bit OS is needed to address more than 4GB.
