for normal gaming just leave XFR to do its things, some boards allowed you to increase the limits that hold XFR back like the Performance enhancer settings on Asus boards.
For benchmarking or rendering it would be better to try and get your all core clocks up but not many will do 4.3 all core, mine does at 1.5volts but thats for a quick 3dmark run before i switch it off. Last time i won the silicon lottery was about 2001
Interesting. I’ll give that a go later and see how it effects GPU benching, if at all.
