Overclocking my 2500k

post #1 of 20
Thread Starter 
Alright so i got my 2500k and Sabertooth P67.

Following Sins overclocking guide he said to set the multiplier for the cores between 40-45 and then go up by one and to pay attention to the vcore.

So i begin to do this and im at 4.6ghz and the vcore was auto set at 1.52v is this normal for it to do this and all i have to do is lower it within the bios?

Here is a picture of the cpuz screen while its in idle:



Whenever the cpu goes underload:

No that vcore is not normal, way to high for those clocks. With a 4.6 ghz OC you should prob set vcore to about 1.33. Also make sure you have PLL overvoltage enabled.

reduce the vcore to around 1.4v and hit prime blend for a few mintues to see whther or not it bsods, if it doesn't lower until it becomes unstable. 1.52 is considered very high for that overclock. Majority of the chips I have seen can do 4.5 with less than 1.4v.

Yeah they should be able to, my chip will do 4.5 @1.28 vcore

im guessing on my board its called Internal PLL Overvoltage? I figured they were not normal, from what i was reading is that D2's revisions were supposed to clock better Ill go ahead and change it to 1.33 and see what happens.

Try these settings:

VCCSA Voltage: Auto it's advised not to touch that one
VCCIO Voltage: Auto for now
CPU PLL Voltage: 1.75v
PLL Overvoltage: Enabled
PCH Voltage: Auto
VRM Frequency: 350
Duty Control: Extreme
Phase Control: Extreme
Digi + VRM Current Capability: Auto - 100%
CPU Multi 45 by each core
CPU BCLK: 100 sb doesn't like changes in bclk
CPU voltage: 1.3v Manual
DDR Voltage: Rated stock volts
Spread Spectrum: Disabled
LLC: High or Ultra High (check which one works better for vdroop)

Test those with an hour of blend each time and reduce or up vcore when bsod.

Also keep the power saving featues on ie c1e etc (doesnt effect overclock)

The OverClockers BSOD code list
BSOD codes for overclocking
0x101 = increase vcore
0x124 = increase/decrease vcore or QPI/VTT...have to test to see which one it is
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore
0x3B = increase vcore
0x3D = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary, can also be unstable Ram, raise Ram voltage
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

and for all of you with GB mobos you should read this;

Thanks I wanted to try for 5ghz so what increments do I start taking to see if I can even get there?

exactly the same but depending on stability change vcore to 1.4v and work your way down or up.
