I just got an i5 750 and ASUS P7P55D second hand. It was a good deal, and I'm pleased with with the setup so far. Many thanks to those on various forums who gave input on the build (CPU, Hyper 212+, hard drive).
I'm planning to overclock it now. It's currently sitting happily at 3.4GHz at 1.25v. I want to push it higher, of course, going for 20x200 bclk. I've read some guides on this, so I'm pretty confident about what I need to do.
However, I'd like to be able to use EIST to throttle the CPU when it's not under stress... no sense wasting power and creating extra heat when it's not necessary. I've read conflicting information about this. Some say it must be turned off to achieve a stable OC, others say it can be left on.
Currently, my CPU clocks down to 9x when idle, so that's 1440MHz (@160) and it seems fine. But it is also supposed to reduce the voltage when it does this, is it not? So as I increase bclk its idle is going to go up as high as 1800 assuming it keeps the same multi. If the chip is only being supplied with the amount of voltage it needs to be stable at 9x133, then I doubt it's going to be stable at 9x200.
Looking at hwmonitor right now, though, the motherboard doesn't seem to be decreasing the voltage when idle. It stays at 1.2488v even though the multi is at 9. But I didn't disable EIST in the BIOS and it's reporting very low wattage in the hwmonitor power section (14 watts at idle).
Perhaps this means that my mobo has figured out what I'm doing and all is well--it's still going to decrease power consumption, but it's not decreasing the voltage in order to keep the system stable?
Ergo... I can leave power saving on and OC without worry! Right?
