Exactly as you described. Increasing the vcore and multiplier and booting up and running stability tests. I didn't fiddle with anything else. I did find, however, that stability issues have started to creep in over the past few weeks so I've had to up my vcore to 1.20. I get around 35-40c temps and at full load nothing more 80c.
I've since looked in better cooling options and another case, so I'm thinking of seeing if I can push it further and increase the vcore a tad.
I should receive my Be Quiet! Dark Rock Pro today so will slap that in tonight and see what the temps are. I can post the data if it helps.
