I5 2500K wont go past 4.4 Ghz

[ruthless_villain]

Hi, title says it all cant push my 2500k past 4.4 ghz i tried different volts, even let the motherboard decide all the voltages but cant go past 4.4 its a msi p67a-g45 motherboard and 4gb xms3 corsair ram, is there any option i should be looking out for in the bios just really confused as i am new to p67 so thanks alot

sorry just realised this was in the graphics section, sorry people

4.4Ghz isn't exactly slow y'know. Disable cpu spread spectrum if your mobo has it - that MIGHT help. You will likely just have to accept this individual chip is only capable of 4.4

I've used that board. Capable of 4.80GHz stable OCs. What settings have you used?

 

[ruthless_villain]

thanks for suggestions, everything i could think of is below

44x100

Cpu base freq, 10khz

Internal PLL disabled

Eist disabled

Dram auto

EMP disabled

Spread Spec enabled

Low vdroop

1.3 Vcore

Dram v 1.64

All cores active

Limit cpuid max disabled

Execute disable bit enabled

Intel virtualisation tech enabled

Power technology custom

C1E support enabled

Overspeed protection disabled

Intel C-State disabled.

As i said, disable spread spectrum.

 

[ruthless_villain]

nope, no difference one thing i cant understand is that it will boot, post, and let me use bios but will not even attempt to load windows??

 

[SmoulderingCircuits]

My 1090 did the exact same thing, coincidentily at 4.4

 

[ruthless_villain]

i blame windows

The settings on the MSI boards are different to the Asus ones, PLL should be enabled though. If it's not booting into Windows you need to up the volts, for 4.4 try 1.32v and if that does not work try 1.325 then 1.33, 1.335, 1.34 and so on until you can boot into Windows. If you have a load line calibration setting set it to ultra high and disable speedstep and turbo boost as well.

getting a very pleasing overclock to brag about is one thing. using it is another.

if you had a sports car, and 'screwed' it every day, it wouldn't last very long.

i suggest overclocking, then throttling back a little bit for general use.

i can get 4.12GHZ from my 1055T, but long-term use at that clock would slowly kill it, so i throttled it back to 3.81GHZ.

remember, 1055T's base at 2.8GHZ and turbo at 3.4GHz(ish). so, having an extra permanent 1GHz on a hexacore with a locked x14 multiplier isn't too bad. and, i won't be killing it!!!

this should apply to any overclock

 

[MSIRawZ]

PLL should be enabled.

Disable power tech and spread spec. Disable turbo boost.

Up vcore to 1.37v, up multi to 47x.

Thanks alot Rawz, tried everything and it works

one thing though when under full load the cpu volts changed automatically and its very close 1.4 and im not liking it tbh, how can i stop it from changing auto

 

[MSIRawZ]

Awesome

Yeah its an issue with MSI boards that. Low vdroop enabled?

Only other suggestion is drop vcore to 1.36v though it may not be stable at 4.70GHz. So if not, drop the multi to 46x.

managed to get 4.7 stable on 1.355v so goes up to 1.376 max and wont go over 73 degrees witta mighty NH-D14 so im a happy man

GJ mate.

 

[ruthless_villain]

GJ mate.

thanks, i actually clocked it back to 4.4 as 4.7 is the max i can go and it seems to reset the overclock sometimes, and then it wont boot into windows and i got to do it all again, too much trouble and im to paranoid and lazy to stay at 4.7 so thanks for the help Rawz and the rest of you but will be @ 4.4 for now maybe if i go water cooling, or switch motherboards i will try to go back to 4.7 i dunno, so thanks alot.

 

[dugdiamond]

nice one

 

[NoKz]

Congrats on a nice overclock.

turn loadline calibration (vdroop) up and see if it helps stablise it at 4.7
