My target is to hit 4.5GHz using the lowest voltage as possible to have it stable, I've the Gigabyte Z77 D3H motherboard (F18) BIOS, The setting I've changed is LLC to Turbo and rest is default,

I used Prime95 to stress test the CPU using 'In-Place Large FFTs' test, here's the list of errors for each VCore,

4.4GHz - BIOS VCore 1.230V, CPU-Z Lowest 1.248V, Highest 1.260V
4.5GHz - BIOS VCore 1.230V, BSOD straight away
4.5GHz - BIOS VCore 1.235, Core 2 stopped after few seconds Prime95
4.5GHz - BIOS VCore 1.240V, BSOD straight away Prime95
4.5GHz - BIOS VCore, 1.245V, BSOD after few seconds Prime95
4.5GHz - BIOS VCore, 1.250V, BSOD after few seconds Prime95
4.5GHz - BIOS VCore, 1.255V, BSOD after two minutes Prime95
4.5GHz - BIOS VCore 1.260V, BSOD after four minutes Prime95
4.5GHz - BIOS VCore 1.265V, BSOD after eleven minutes Prime95
4.5GHz - BIOS VCore 1.270V, Core 2 stopped after four minutes Prime95
4.5GHz - BIOS VCore 1.275V, BSOD after two/three minutes Prime95
4.5GHz - BIOS VCore 1.280V, CPU-Z Lowest 1.284V, Highest 1.308V

4.3GHz @ 1.236V,

Those temps are good for 4.5GHz under Prime95. I get 70-75c on my D-14. If you want lower voltage try downloading Gigabyte 3D Power app, and lower the LLC a step at a time until you find it isn't stable. Then stress test.

4.5GHz 1.27V is stable for my 3570K. It's still a good voltage imo. The max VID is apparently 1.55V for these CPUs according to Intel. Just have to watch the temps and yours are great. Are they accurate? I use Coretemp.

I'll download Gigabyte 3D Power App and try lower the LLC voltage, in BIOS should I set LLC to Lowest?

Do I up the Dynamic Core LLC one step at a time until it's stable at Prime95 stress test?

I think the temps are accurate as I always use RealTemp
