Hey guys,

I have an i5 3570K and MSI Z77A GD65. I’m currently clocked at x42 with the voltage set to “Auto”. The system appears to be stable (two hours Prime95 and 71C max temps).

However this new MSI board has a lot of setting that I’m not familiar with. I’m hoping someone can educate me before I take the OC any higher.

EIST = Enabled
Intel Turbo Boost = Enabled
Intel C-State = Disabled
C1E = Disabled
OverSpeed Protection = Enabled
vdroop Offset Control = Auto
CPU OCP Expander = Default
CPU Core Engine Speed = Auto

Are these settings correct / optimal for a 24x7 overclock?

Cheers,

Matt.
 
overclocking MSI doesnt require a degree in electronics thankfully. The default settings will allow you to clock quite freely.

If you are hoping to push a little further then I'd disable the turbo.

Overspeed Protection changes a CPU register flag - no-one knows what this does (it may be a throwback to early engineering samples) what we can tell you is it makes no difference to the current retail processors

CPU OCP (OverCurrent Protection) Expander increases the current limits of the board, HOWEVER, these limits are already more than the CPU could handle in all but the most extreme OC attempts.

The CPU Core Engine Speed controls the PWM IC operating speed and again, should have no effect on normal overclocking

If you want to push the CPU to its limits then:

1. Set “Internal PLL Overvoltage” to “Enabled”
2. Set “HPET” to “Disabled” (this item is under MSI Mainbord settings -> Advanced -> Integrated Peripherals -> HPET Configuration)
3. Set “EuP 2013” to Disabled. After complete the setting, please power off the system and then power on again. (you can find this item under ECO-> EuP2013)

just be careful because Ivy Bridge is much more voltage sensitive than older gen CPU's, a little extra voltage creates more heat than before.

I'd keep some of the power settings (c-state and c1e) enabled for lower power consumption when idle.

Cool, thanks for the information. This helps a lot :-)
 
ScottiB, could you explain, why to do steps 1-3, please ? I'd do exactly the opposite for "optimal 24/7 o.c" (and not pushing to the limits). Especially I'm interested in EuP 2013 which doesn't work like it supposed to do.
