Hey,
I upgraded my PC two days ago with i7-6700k, Asus Maximus VIII Ranger and 32GB of HyperX Fury 2666MHz.
I used my old PSU (Chieftec 750W 80%+) and CPU cooler (Hyper 212 EVO, not the best I know).
I first used updated BIOS and then used "Load Optimized Defaults" settings from the MB and after monitoring temps I was shocked to see them go up to 90 Celsius and the Core Voltage in the Asus AI 3 was hitting slightly above 1.4 Volts, and this is at 4GHz!!. I shutdown the Prime95 immediately, kept looking and a bit later I got a BSOD.
So, I tried to start "overclocking" it manually, trying to get to 4.2GHz with minimum voltages, but I could not get it stable even with 1.4 Volt core voltage.
I managed to boot few times to Windows at like 1.395 core with LLC level 5, started Prime and BSODed in few minutes. Other than that, it always BSODs on Windows boot screen or before.
I managed to get it stable at 40 multiplier, 100MHz BCLK, 1.31 core voltage and the temps are around 60 under max load but anything over 40 multiplier seems to be impossible in the safe range.
I tried with only one RAM stick, tried with 2133 MHz, 2400 MHz and the XMP 2666MHz speeds and even ran a memtest86 overnight to try to make sure it's not the RAM and it found nothing.
So, the to the question itself. What do I have left to try? I don't necessarily want to overclock it, just to get the temps and voltage down while keeping the 4.2 GHz, as that's the least I think I paid for...
It's been a quite long time since I last played around with these, my i5-2500k was stable at 4.6GHz for 5 years now. I hope I'm just really really badly derping here and not realizing I'm doing something wrong.
To sum up what I've done so far:
- Update BIOS
- Reinstalled CPU cooler
- Ran memory checks, tried different speeds and rotated DIMMs
