Hi
@GideonBlack. I've no problems with F7. I'm running at 4.9GHz on my i7-8700K. I found just using the basic overclocking setting, that if I tried for 5GHz it would crash doing heavy duty stuff like running Prime95, etc.
I also had my system crash at 4.9GHz running under Arch Linux yesterday whilst compiling code for around 20 or so minutes using all of the 12 cores. It wasn't a temperature thing as I have water cooling, and it didn't get past 76C, well under the 100C limit. I re-ran and it compiled flawlessly! Go figure!
I wonder if the F7 BIOS is changing the CPU voltage levels a little different to the previous F6 BIOS, and your CPU is on the edge. I'm not experienced in OC issues, so maybe have a look at some other websites to do with overclocking.
I also am using the 'DMAR' setting in the Drop Tables along with the PluginType enabled (ticked) in the ACPI section of my config.plist. This gives me better (native) control of the CPU power management.
- What overclocking frequency are you setting your CPU too?
- What are your system logs saying (if any) regarding the crashes?
- Also, are you overclocking your RAM? I leave mine at the Profile 1 setting... I have 3600 RAM.
- Is it crashing whilst only under heavy load?
