Hey everyone! This is my first time posting on tom's hardware, I was hoping I'd be able to avoid doing it but after A LOT of trouble-shooting I simply cannot find the answer I'm looking for.
Yesterday I jumped onboard the overclocking-train with my i7 4790k with 2 goals in mind:
1. Increase clock-speed (duh)
2. Lower the core-voltage to reduce temperatures (I wasn't satisfied with the stock voltage & temperature)
(Worth noting - Also enabled XMP for my 1600mhz DDR3 Corsair Vengeance sticks 2x4gb aswell as setting up a custom curve for my H80i liquid cooler to keep the temps down)
Once I achieved a stable overclock at 4.5ghz with 1.250 Core Voltage, I started lowering the voltage by 0.025 at a time to find a stable and low voltage, I managed to reach a stable voltage at 1.170 with my 4.5ghz clock-speed.
Now here's the issue. While tuning my 4790k I obviously used manual voltage while stress-testing it (AIDA64 and Prime95) and it worked perfectly, temps didn't exceed 70c at full load and I was satisfied.
As I then changed to adaptive voltage in my z97-a ASUS UEFI (To make use of the power-saving settings while the CPU is idle and whatnot) and set the maximum turbo voltage to 1.175v and booted, the core-voltage ramped up to 1.233 under full load (Cinebench R15).
No matter how many pages of forum-posts I've scrolled through, I still haven't found the answer to my issue.
Why on earth does my cpu insist on squeezing out 1.233v in adaptive mode, when it's stable at 1.175 in manual? How can I arrange so that adaptive mode doesn't exceed my intended voltage?
Thanks in advance
