Hey guys!

As the title says im planning on overclocking my cpu, never done it before so not sure what to do exactly, tried reading up online but it's rather confusing.

Is it a case of going into bios and upping the cpu ratio a little? or is there more to that?

Also a bit confusing when it comes to the boost feature.

Any help will be greatly appreciated!

Cheers.
 
it is very simple, only took about an hour to learn how and then try to oc my old i5.

what cooling do you have for the cpu?

also that guy --^ wazza helped me a lot with the more advanced speeds.
 
what did you want to clock to?

for 4.5ghz you can try setting

cpu/pci clock to 100
cpu multi to 45x
loadline calibration to medium
cpu voltage to normal then set dvid to +0.015v
set vcore voltage response to fast and pwm phase control to extreme performance

all else can be left on auto,enable xmp profile 1 for your memory then stress the cpu in prime95 and look in cpu-z to see what the load cpu voltage is

also download coretemp to monitor cpu temps at load

ideally you want to be around the 1.35v cpu mark and under 80c but it depends on each cpu

id be happy even getting 4ghz.

Finish work at 1pm so will have a fiddle when i get in then.
 
for 4ghz

cpu/pci clock to 100
cpu multi to 40x
vcore voltage response to fast
pwm phase control to extreme performance

shouldn't need to touch voltages but can lower them if they are too high you would need to check while stressing the cpu

Cheers mate, thanks for the help, would i even need to stress test it with such a low change? or is it a must?
 
only to see what the load cpu voltage is,if too high you can lower it with a negative dvid or a lower level loadline calibration
 
with the same board and chip and a cheap £23 air cooler my old i5 was very happy at 4.4ghz. only changed the turbo multipliers to x44, llc to extreme, voltage response to fast and lowered the vtt to 1.650v.

ran like that for 2 years with no trouble and was clocking right down when just web browsing. there was a topic i started about a year ago for it, should be easy to find.

4.5ghz was too much for the air cooler.
 
Before OC I prefer to disable all the energy saving options (C1E, EIST etc.), set a fixed voltage such as 1.25V or 1.3V then start to tweak the CPU ratio. If you've got a standard 3570K you may go to 4.3GHz (CPU ratio 43 while the bus set to 100MHz) on 1.25V or 4.5GHz on 1.3V. Good luck :)

4ghz is easy leave all settings stock (or reset to default) go into advanced frequency settings then advanced cpu core features and change the turbo clocks from auto to 40. Then change the xmp profile to 1. That's all i did even have mine set to 4.1 and has been since i built the system.
