Hey guys, I just noticed a couple of things:
1. With regard to power profiles, there are a few things at work here. The bios has EPU controls, AI Suite II has EPU controls, and Windows has its own power management settings. All have the effective capability to reduce/increase the voltage on the processor, and kick into turbo when needed. I leave EPU disabled in the bios. From a little fiddling around, the AI Suite II EPU power settings seem wonky (I don't like how little customization I get, and the interface doesn't seem to work as it should), so I've decided to just set that to High Performance (i.e., no vCore V downgrades, no chipset V downgrades, keep bios setting fan controls) with the idea that that effectively turns it off, and manage the power settings via Windows 7 power management. Setting to balanced in Win 7 seems to be working out fine, enabling the voltage to fluctuate and turbo to kick in as needed. In the advanced settings for my Balanced profile, I've got minimum processor state set to 5%, max set to 100%, and system cooling set to passive.
2. I'm finding the ability to manipulate CPU voltage in the TurboV app inside AI Suite II interesting. I'm just running my i5 2500k at the stock multiplier right now, testing stuff out. In AI Suite, I've got my CPU voltage set to 1.000 volt, which causes the core voltage (as reported by CPU-Z) to fluctuate between .840 (idle) and 1.184 (under load in LinX 0.6.4), a range of .344. I tried setting the cpu voltage at .950, 1.050, 1.100, and 1.200, and in each case the the range from idle to loaded volts measured in CPU-Z was either .344 or .352 V. Does anyone know what controls how far the CPU is willing to throttle down or crank up the CPU voltage setting? In the bios, I have internal PLL overvoltage disabled, speedstep enabled, CPU offset is at .005, and LLC is enabled.
