Memory in question is Kingston fury beast KF560C40-16 (32GB total)
I used memory test program memtest to boot and run memory test, it showed no errors on 6000. However, when I tested memory using Testmem5 with Extreme1@anta777 configuration it did show some errors. Those error were not present when memory is set to 5600. Ram is placed in correct slots, otherwise system won’t boot at all (I did have them in wrong slots initially). This is clearly something with BIOS. Just to make it clear, DOCP profile with memory speed set at 5600 I am experiencing no issues. Obviously something is not tested thoroughly with this memory. I am running 0805 bios. Did someone manage to get 6000 memory 100% stable without games randomly crashing?
