I noticied that when i turned on expo i had alot of blue screens, ran memtest and i got 10k errors in 7 minutes. My pc builder says

You'll notice that the EXPO/XMP profile isn't enabled in the BIOS settings as it is an overclocking feature. As much as we'd like to use this feature to set speeds higher, anytime overclocking is involved there is a risk of instability. Every use case is vastly different and we'd prioritise stability over overclocked RAM. There are endless amount of combintations available for PCs which makes it near impossible to manually adjust frequency, voltages and timings to be stable. Rest assured, the memory kit you've received is the advertised speed and can be compatible to operate at those speeds with manual trial and error.

what the hell manual trial and error am i supposed to do???

edit:
RAM: Lexar THOR 32GB (2x16GB) 6000Mhz CL32 DDR5, they are placed in the the two slots furthest away with a gap in between
