I recently picked up a 7700k from a friend of mine, flashed the bios to the latest release, threw in (very gently) the 7700k. OS booted perfectly and recognised the cpu, idle temps ~30c and on load didn’t go past 70. Great, time to overclock.
This is where I ran into problems, I set the ratio at e.g 47 on all cores. The rest left on auto. Boots fine but in hwmonitor the freq won’t go past 4400 and single core of 4500. CPU-z shows 44x (8-47). Things I’ve tried:
- Older 3401 bios - Older 3201 bios - Gamers OC Profile preset - performance and balanced plans - cleared cmos and reconfigured - uninstalled AI Suite 3 and AI Cleaned - used configurations other users have used with a 7700k and z170 - clear cmos and only change ratio - disabled all power saving in UEFI - Completely reinstalled Windows on a new drive.
I’m running out of ideas, others have had success with Kaby Lake.
I was running a 6600k at 4.4 before upgrading.

1) Reset the bios to defaults (F5) 2) Set the AI Overclock Tuner to Manual 3) Sync All Cores 4) CPU Core Ratio 47 5) CPU Core/Cache voltage 1.25v - 1.30v 6) DiGi+ LLC level 6 7) F10 and Enter to save and exit
