I see what you meant about the multiplier, it's saying 24.5 but you're running 4815. Maybe if you update CPU-z to the new version that'll fix that up. As for the rise in temps that's quite normal when increasing the speed. This is whaere you're going to have to set your voltage manually if you want a bit more speed out of it. Notice how it jumped all the way to 1.55V, Try setting it manually to 1.5v and set the CPU LLC in the digi section to ultra high. Then try again and see if it'll run without losing workers. This is the point where volts can rise very quickly. We need to control the voltage a bit more and the settings I gave you should keep it to around 1.51ish under load.
