So, I'm fine with 4,0 GHz. Anyway I have strange proccessor batch. For 3,6 GHz it needs 1.232V under load, for 3,8 GHz it needs 1,304V under load, and for 4,0 GHz needs 1,376V under load... it has big gaps for little change in speeds...

Mine VID is 1,225V and batch Q816A678. Although it doesn't heat a lot. At 1.376V max temperatures 64 C with air cooling. So lot guys here with earlier batches that need less voltage for 4,0 GHz but their temperatures go like wild...
