ALSO small mistake i did on my post.
For the context i have the binary version of unreal downloaded from the launcher and it works just fine with every big sample project, until this morning when while opening i had an “access denied when trying to read from adress 0xffffffff”, plus sometimes the iCue software (for managing the ram lights) can’t connect to the ram and i remembered that i did NOT stresstest my ram.
So I will try it now with MemTest86, they say i need a flash drive for boot, but i only have an external 4Tb ssd with 1Tb of data, can i use it instead? (i don’t think so but maybe??)
