Okay cool, thanks dude! I get what you mean. I just was a little unaware of how one recognizes that need for more juice or not.the xmp profile should do whatever is needed to set it to 3600. you should not have to do anything manually.
no one can tell you for sure if you'll need any voltage bump, that's the trial and error part of it. set it to 3600 and if it runs stable, then it does not need a bump. if it does not, try the smallest bump you can and see if that helps.
overclocking is a trial and error effort no matter what part you are working on. there is no shortcut to the process.
