Hello. Lowered pCore to -125mV, pCache to -75mV, everything else 0. Getting 19k CB r23 multi core with e cores disabled in the bios. Constant. Consistent. TVB is on.You are welcome.
Most people find that at a certain point, increasing the core offset does not accomplish anything. When running Cinebench, what sort of improvements to temperatures or performance do you see when going from
-85 mV for core and cache to
-85 mV cache and -100 mV core or -150 mV core or -200 mV or finally -250 mV core?
I am just curious. Is there any improvement that you can clearly prove when Cinebench testing?
With some previous gen CPUs, there was no real improvement after a difference of about 50 mV. You could set the core offset request to the max, up to -1000 mV, and the CPU would simply ignore the majority of that request. The cache voltage was the main limiting factor.
I'll try lowering pCore to -75mV as well to be in sync, and for any potential stability gains (I was stable at -80mV pCache but just lowered to -75 to be safe).
Previously no undervolt yields throttling thus 14-17k score w e cores disabled.
Edit. Lowering both to -75mV yields 16k CB r23. -150mV pCore, -75mV pCache = 19 CB r23.
Edit 2. IDK how much lower on pCore will do anything. I jumped straight to -150mV because someone told me pCore can be 2x the undervolt of pCache.
