Hey all!
I'm new to this forum so be gentle :)
I've been tearing my hair out the last few days trying to work this out and I have no idea what is going on. I'm by no means an expert overclocker but I wouldn't call myself a novice either. I've managed to overclock my 4770K to a modest 4.3GHz at a fixed voltage of 1.19v and temperatures under load in OCCT are acceptable (just under 80 degrees on my aging H50 cooler). When the CPU downclocks to 800MHz in Windows, the voltage doesn't drop, just stays at 1.19v so I've enabled adaptive mode in the UEFI hoping to use the power saving features that Haswell offers, and while it does lower the voltage when idle to around 0.72v, the voltage jumps up to a whopping 1.27v in OCCT which causes the CPU to overheat very quickly and the test to fail. I've tried manually setting up an adaptive voltage but no matter what I set it to, it makes no difference.
Has anyone had any issues with this? I'm wondering if I'm doing anything wrong or if the UEFI is just broken?
Thanks all
