Tie vypnute pamatove kanaly to nijak neovplyvnili (preto mi aj nie je jasne preco to AMD vobec robilo a zbytocne si ten test devalvovalo).Na HardOCP to pretestovali:

Also, in notes that were shared by AMD on the Intel system being used, it notes that it is running 2400MHz dual-channel memory with a 16GB footprint. A bit odd since the system supports quad-channel RAM, however in the testing I have done in the last couple of days here, it seems that this particular Blender scene is not tremendously sensitive to memory bandwidth. I have run tests with RAM up to 3400MHz with etc. Toggling back and forth between dual and quad channel memories at cited 2400MHz seems to make no difference at all in this particular test, so if you see someone complaining about that, their point is moot for this discussion.
