Friend needs help with Asus MAXIMUS VII RANGER. He lost the silicon lottery, 4790K doesn't even do 4,6Ghz fully stable. Now he would be okay with stock Turbo speed of 4,4GHz but ASUS multicore enhancement is not working. There is only two options: auto and disabled. Results is the same with both, clocks drop to 4,2GHz when all 4 cores are in use. Is there supposed to be third option? Latest bios is installed.
