is CPU ratio all i need to change?

[MasFBailey]

Hi im using an i5 3570k and i wish to overclock it for better gaming performance.

im using the Asrock axtu software, am i right in thinking changing the CPU Ratio to 40 will give me a 4ghz cpu?, the reason i ask is that windows and speed fan still show it as being 3.4 ghz.... thanks in advance

Here is an in depth guide for you:

Oops that isn't haswell! Here is a better guide for your chipset, its even for Asrock MBs!

You also will need to change the voltage to stabelize the higher clock frequency. If youre using a stock cooler don't do this. for that cpu id try 1.18 voltage for that frequency should be stable if not bump it up another notch. Use prime95 to test the stability of the overclock once you manage to overclock it stabily

thankyou ill have a look!

ahh i dont have a cooler as of yet, however it never exceeds 50C when set at 40 even with 2 770's sat right next to it at 70C

thats idle did you ever test the cpu at 100% usage chances are with a stock cooler at 4.0ghz it will hit crazy high temps

Sorry but by voltage what do you mean, under the voltage tab there are 7 options

Thats while running heaven engine on ultimate settings

 

[firo40]

What settings are provided under voltage?

 

[MasFBailey]

What settings are provided under voltage?

They are :
CPU voltage offset +0v
DRAM voltage 1.585v
PCH voltage 1.059v
VTT voltage 1.076v
cpu pll voltage 1.832v
vccsa voltage 0.925v
igpu voltage offset +0mv

btw thankyou for the help

Does it state what the current voltage is at? If you can find that out set the cpu voltage offset higher to reach 1.18v

all i can find is cpu vcore voltage which hovers between 1.082 and 1.110, also my clock speed sporadically drops from 4000 to 1600

 

[firo40]

when you go to change the cpu offset voltage what options are you givin. The vcore is the cpu's voltage which seems kinda low for a 4.0ghz overclock, probably why all this issues are happening

 

[firo40]

also have you disabled turbo core?

 

[MasFBailey]

also have you disabled turbo core?

i havent seen any options for turbo core also the options are either + or - 0.005 v

 

[firo40]

try to increase it .100 if you can

 

[MasFBailey]

try to increase it .100 if you can

ok it is now +0.100v however ever 20 seconds or so it still changes from 4000 to 1600
