Overclocking i7-4790k help

[JBVector]

Hello
I'm trying to overclock my i7-4790k using throttlestop, but the "set multiplier" doesn't go higher than 44 T, and neither does the Turbo Ratio Limits. The hyper-threaded cores are greyed out. I've tried disabling Turbo and SpeedStep, but it doesn't work. My windows power setting is on High Performance. How do I get higher overclock?

Also, what does the non-turbo ratio do?

What motherboard are you using? My 4790K does 4.7 easily in an ASRock Z87 Extreme6 and all OC adjustments are made in BIOS.

You'll need a Z87 or Z97 mobo to get maximum performance out of your 4790K. Your Dell has a workstation board not designed for overclocking. I just looked up the specs on it.

Ok thx. So it's completely impossible with this motherboard?

You're locked to whatever the turbo limits to. If you want 4.6 to 4.7 you'll need an unlocked board.

Ok. Thanks for the help guys.
