I read the page about the AMD RYZEN 51400, it only support a memory with maximum frecuency around 2667MHz. I install a memory , it has the next characteristic:
CORSAIR DDR4 8 GB 2666 MHZ
it is the page https://www.amd.com/es/products/cpu/amd-ryzen-5-1400
My question is the next:
The maximum frequency that my pc supports is 2667MHz for each memory or the summation total cant pass the 2667MHz 's limit
I would look at the support page for your motherboard and see what your motherboard supports and whether or not the model number of your ram is on it's QVL support list.
