Ok so here are some pictures from my BIOS , all i want you to do is tell me what settings to change a reply would be greatly appreciated!

All i want to do is to overclock my system to 4GHz.
I was told to set my max turbo core speeds to x40
But im not sure what settings to change to do this.

On the first screen you put up select Turbo 4.0GHz and that's it, Test to check it's stable.

ImTooSimple · 30 Jul 2013 at 17:09

Ok how do i test if its stable or not?
Like how do i run prime95? Im not very smart when it comes to this type of PC.

nlel1975 · 30 Jul 2013 at 17:15

Run Prime95 overnight.

I used to run my i5-2500k at 4.6ghz with a voltage of 1.35v due to the hot weather my temps went up by about 10C

So I then tried to find a stable 4.3ghz at a lower voltage, both reducing the voltage and lowering the speed contribute to lower temps.

So I tried 1.31v @ 4.3ghz Prime95 froze instantly, then tried 1.32v @ 4.3ghz Prime95 went for about half an hour then froze.

Finally tried 1.33v @ 4.3ghz Prime95 ran all night at a max temp of 74C which was where I wanted to be temperature wise as I was getting over 80C at 4.6ghz

Ok, but how do i run Prime 95? Like a step by step guide in easy words.

Install it then run the SmallFFT test which will get your temps to rise up the quickest, just leave it running until it freezes, blue screens or continues to run for several hours after which you can be fairly certain its stable. If any of the individual threads stop its a fail.

Some say then to run the Blend mode just to make sure but I have never found this necessary.

ImTooSimple · 30 Jul 2013 at 17:33

Can someone please show me to run a test?

ImTooSimple · 30 Jul 2013 at 17:35

Ok i think ive found out what to do.
1. Open Prim95
2. Run a torture test
3. Use these settings http://gyazo.com/197c890589ef088c2450e1523bb83aa7
4. Leave for 8 hours

Would i be right?
Last question how do i know if its completed succesfully or if it has failed?

well small fft only tests one part of the machine. not the ram or anything else.

nlel1975 · 30 Jul 2013 at 17:39

I only suggest running SmallFFT first so you can quickly see how high your temps might go, otherwise many people say Blend is better as it tests CPU and RAM.

If all the threads are still running after 8 hours or so (ie they are still green not red) then you can be fairly certain you have achieved stability. Good Luck!

weird that you need 1.33v to 4.3 and only 1.35v to 4.6... are you sure that is nothing else holding your overclock?

ImTooSimple · 30 Jul 2013 at 17:43

What do you mean by "they are still green not red"? Like where abouts do i see that?

When you run it you will see what I mean, each thread has its own window and if you have a dual core CPU you will have two of them, if you have a Quad core CPU without hyperthreading there will be four, and if you have an i7 with hyperthreading there will be eight.

Don't worry as soon as you fire it up the first time all will become clear, its a piece of cake.

I am not 100% certain that 4.6ghz wasn't stable at 1.33v I am not sure I ever tried it. I may give it another go when things cool down to see if it was stable at 1.33v if not I know 1.35v definitely was.

Ok, also last thing is my i5 2500k temps with the stock cooler too high?

Idle http://gyazo.com/8767536d7cad0a7107ce3d3868c50b21
Load http://gyazo.com/b18f596114e687f436b1d027554abab5
Are these normal for a stock cooler?

ImTooSimple · 30 Jul 2013 at 17:53

Wait its averaging 90 DEGREES!

They seem a bit high especially the load voltages, are you running things at stock and getting those temperatures? Seem a bit high if not overclocking the CPU but this weather is having an affect on temps I have noticed.

Put it this way with my i5-2500k @ 4.3ghz with a core voltage of 1.33v I am getting as high as 74C under Prime95 smallfft you are getting those sort of temps too and if you are not overclocking anything that is quite high.

I have an Akasa Venom CPU cooler on mine.

Seems like you are trying to overclock with a stock cooler, never a good idea!

wazza300 · 30 Jul 2013 at 17:56

get a better cooler before you do any overclocking,stock coolers are useless
