Leaving LLC on Auto?
Leaving LLC on Auto?
I own an 8700k + Aorus Gaming 5. What I needed from this build was a stable 4.7GHz across all cores. My current configuration gives me mid 70s in Cinebench and mid 80s in AIDA with CPU/FPU/MEM stats, while HWMonitor shows a max voltage of 1.308. One thing to keep in mind is my LLC is set to AUTO and I’m not keen on testing it with lower voltage and higher LLC. Given that my temperatures and voltages are within normal ranges, should I just keep things as they are?
Your temperature is quite high for a 4.7 Ghz overclock. I don't think you'll need 1.308 Vcore for this speed. Although each chip varies slightly, 4.7 Ghz usually operates at around 1.25 Vcore or less. It's unlikely any 8700k model needs more than 1.3 Vcore (my 8700k is stable at 1.17 Vcore for 4.7 Ghz across all cores). I recommend gradually reducing the Vcore by about 0.05 each time and running prime95 version 26.6 with a small FFT test for two hours after each adjustment. If it handles it, continue lowering the Vcore and repeat the process. For LLC, check your motherboard's documentation to see available modes—consider sticking with the standard setting if possible.

I recommend gradually reducing the Vcore by about 0.05 each time and using prime95 version 26.6 with a small FFT test for two hours after each adjustment. If it performs well, continue lowering the Vcore further. For LLC settings, check your motherboard's documentation to see available modes; opting for the flat horizontal line can help maintain consistent voltage during full CPU load.
