Turn off all power-saving options and Turbo Boost. Simply boost the VCORE to its default level. Begin at 1.25V and execute a Prime95 Small FFTs test (avoid the blend test). After 10 minutes, if the system remains stable, reduce the VCORE slightly and rerun the test. Continue this process until the PC begins to fail or threads stop working. After identifying the optimal VCORE, perform another Prime95 test matching the usual duration for full stability. Maintain close monitoring of temperature, aiming for a maximum of 70°C.
Just tweak the CPU multiplier and VCORE; everything else can be left out. Restore your BIOS to its standard configuration before proceeding. Turn off any power-saving options—they’ll automatically change voltage and clock speed, which conflicts with overclocking. If you’re worried about saving power, don’t overclock.
Will restart the Bios settings and attempt once more using EIST with Turbo disabled.
Maybe remove the cooler and reapply thermal paste (just in case). I'll check if this helps.
Don't stress about reapplying thermal paste, it seems like the issue is related to voltage instead of heat.
Please verify if disabling both EIST and Turbo is correct. Are there additional power-saving options you're aware of? Consider adjusting the core multiplier to "all cores" and changing x40 to x44. Set Vcore to Override mode 1.2 to 1.3. You can either keep Vcore at auto or set it to 0, as it's already in Override. All other mainboard settings should remain unchanged.

Ohh, it looks like I misread the temperatures in the first post. The correct range is 65-70°C just before the BSD when I tested above 4GHz. With my stable 4GHz and vcore at 1.275, the Prime95 blend test reaches a max of 88-91°C and an average of about 60-70°C.
the evo could face difficulties in managing heat at temperatures between 1.26 and 1.28 on the i5 and around 1.25 on the i7
