Help with i5 650 OC

post #1 of 3
Thread Starter 
Alright, so I got my 650 at 4.0GHZ with HT on, ive been screwing around with it trying to see if I can get anything higher than 4.0, possibly like 4.5 or something.... I was wondering if anyone has got this chip around 4.5 stable. My build wont be on 24/7 just stable enough to game on. (ON AIR)

Right now im at

160x25 = 4.0005
VCore = 1.35v
QPI/VTT Voltage = 1.35v

Is there anything I should be changing other than the qpi/vtt and the vcore? I lowered my ram speeds, I know that part... but are there any other voltages I should be changing? Anytime I try and get it it above 4.0, I have problems....

I disabled that C1E ****, is there anything else I should disable?

C STATE TECH
Its a technology by intel which allows the OS to independently lower the frequency of the cores when the need be thus saving power. If it's disabled then both the cores will run at a fixed frequency. Enabling it will allow the OS to make the core's run at different frequencies thus making optimum use of power.

C1E SUPPORT
reduces your multiplier and voltage to your CPU when it's performing routine tasks that don't require much.

C state tech and C1E support are power saving features. Its best to turn these off while overclocking so your volts and frequencies don't change on you.

CPU TM FUNCTION
TM function is your temperature safety shutdown, if you go higher then the cpu thermal design it will shut down or seriously throttle down automatically

When overclocking you will exceed the thermal design so leave TM function off.

EXECUTE DISABLE BIT
Execute Disable Bit is a system feature that, if present
and enabled, allows the notebook's processor to
distinguish between bits of code that should be
executed and the ones that cannot be, as they pose a
threat to the system.

Your choice to turn Execute disable Bit on or off

LOAD LINE CALIBRATION
If you've disabled C1E and SpeedStep, then turn on Load Line Calibration. Otherwise, leave it at auto/disabled. This feature helps with VDroop.

SPEEDSTEP
that allow the clock speed of the processor to be dynamically changed by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw and heat dissipation. always keep this off

Edit: CPU Spread Spectrum --> disabled
PCIE Spread Spectrum --> disabled

alright, I disbaled all the power saving stuff, I just need help on the voltages now... I should be able to get a lot lower voltage than 1.35 for only a 4.0ghz overclock. Can anyone help me with that?
