Just been playing around a little, managed to get 4GHz on my i5 with 1.265v.
Anyway, now I'm done proving it can reach that value, so I'm planning on seeing how far I can get on stock volts (I hate upping the voltage). Current max speed I've managed on stock is 3.5 (17 x 205), however there are a couple of settings in the BIOS which I don't understand, so if someone could elaborate on them maybe I could squeeze 3.6 out.
CPU Differential Amplitude. 'Different AMP might enhance BCLK overclking ablitiy.' I guess this lessens the effect of increased noise? Range 700mv - 1000mv, 100mv increments.
CPU Clock Skew. 'Adjusting this item may help enhancing BCLK overclocking ability. You may need to adjust NB Clock Skew item at the same time.' Great, if only I knew what effects adjusting it will have. Range is 100ps - 1500ps, 100ps increments.
Now on to voltages:
IMC
CPU PLL
PCH
Also, the CPU has 2 types of voltage, fixed and offset, what's the difference? Does offset allow the CPU to pull a range of voltages where fixed is, well, fixed?
One final thing, my temps at 3.8 are 40ish idle, 75ish load, which seems a bit high in my opinion, my heatsink is getting warm to the touch, and as soon as I stop stressing the temps drop down to almost 1-2c above idle. I had a few issues fitting the cooler, would it be worth my time removing it, cleaning it up and refitting it?
Probably all noob questions, but if I don't ask I'll never learn!
