Hello everyone! I have the Mac Pro Late 2013 model, I've upgraded my RAM sticks manually few months ago with RAM purchased from the Apple Online Store to 64GB. I've discovered that when the Mac Pro is running at full load (CPU+GPU) for rendering, the system will crash and the beeping sound will occur, it tone's pattern indicates that the RAM does not pass a data integrity check according to Apple's support page (https://support.apple.com/en-hk/HT202768). This has happened to me twice, the second time happened just now. The Mac Pro would be able to boot normally after the crash, I've checked the system through Apple Diagnostics and it has not detected any apparent problem. But I do believe this is a discrete problem that is occurring. The system is able to detect all RAM sticks after the initial installation few months ago. Do I have to reseat my RAM in order to fix it or reseating is just a temporary fix? May anyone help troubleshoot this problem or error? Thanks!
