Intel i5 760 help

post #1 of 19
Thread Starter 
Hello guys, im new at OC. And i Oced a bit.. 200mhz. From 2.8ghz to 3ghz.. I know its pretty silly And i wanted to know more about voltages.. how do i know how much to change? I currently have around 1.21 or something.. But in cpu-z it shows 1.184v is that true? And is it enough? And i wanted to know about ram.. i didnt do to it anything, but it clocked from 556 to 600 i guess..
multiplayer:20
freq: 150mhz

Hope for answer.

The voltage constantly changes depending on cpu load. In the BIOS you should set the RAM to 1:1 especially if it's value RAM so you don't kill them

So this is a safe clock?

Definitely, I don't own a core i5 desktop processor but they overclock well, just read the posts on the forum

Okey, btw.. what test programs do u use to test if its stable?

And if u would like to clock it to 3.5ghz i would only need to change voltage and freq or multiplayers?
No need to do anything with that ram? Leave it default?

Welcome to oc.net. Follow this link and fill in your system specs - http://www.overclock.net/specs.php?do=addsystem it will help us offer suggestions..

Need to know things like Motherboard, Memory, CPU Cooling, power supply, etc....

Your overclock is very safe.. There is no (1:1) ratio for us, there should be 2:6 - 2:8 - 2:10, you want it to run at as close to its default speed without going over...

Voltage is fine, although I suggest setting it to a tad over its default in bios. So if its 1.17 default, set it to 1.20 - 1.22, its perfectly safe, intel max is 1.40v.
Make sure your vtt voltage is no more than .050v different than your ram. So if your ram default voltage is 1.65 make sure you vtt is at least 1.15v.

But most importantly you need to have good cooling So if you dont have a decent aftermarket cpu cooler I dont recommend overclocking..

vvt voltage is 1.100
Ram is 1.50

But i ran prime 95 in blend mode and desktop just froze! What could it be?
Umm.. i looked @ i5 760 club and saw this..
http://i623.photobucket.com/albums/t...25runs3ghz.jpg
Guy with 3ghz too, but he has QPI link
Mine:
http://oi52.tinypic.com/4rrvgk.jpg
So its 200 higher.. What is that? And should i worry about that? :d


And when i ran intel burn it didnt even test it.. just said i passed.. run time is like 0.0001 seconds or something like that.


Okey then.. I set it default and started prime95 and again it crashed.. This time @ 61c Sometime it goes to 70c and then crashes.. and i dont have cpu temp warnings on.

It could have something to do with it...

What are your bios settings? There should be something in there for QPI

I would recommend setting your cpu core voltage to 1.25v and your vtt to 1.25v and start raising your bclk 10 at a time and test.. Once it becomes unstable give each a little bump and test again.

Is your ram rated at 1.50v? You want to be sure its set to its default voltage & timings.

Keep temps below 72c under prime95..

What are you using for cooling the cpu? The stock intel barely even accommodates the stock load temps, so overclocking requires an aftermarket heatsink...

The problem is that i cant even test it.. and i dont know why.. im sure it shouldnt crash @ 61c @ default..
And yes.. i have stock cooling.. thats why i dont want more than 3 ghz.. i just wanted to learn so that i can do it later..

All i did was disabled Turbo boost and raised bclk and decreased multiplaier and set vcore to 1.2v.

Well if your just looking to learn, these are the simplest to OC from my experience...

Here is a simple guide - i5-i7-lga-1156-overclocking-guide

Here is what I do
Disable the following:
C1E - aka C-State (C1 - C2 C3)
EIST
Intel Speed Step
Turbo Boost/ Turbo Mode

Then raise bclk and adjust cpu voltage, cpu vtt voltage accordingly...


BUT! if you just load optimized, run it at stock and load prime95 small fft's for about an hour what temps do you see?

I am going to guess its in the range of 60 - 65c, so that leaves very little room to overclock....
