I ordered an i5-760 yesterday for £120 to go with my current mobo (H55M-UD2H) and Nero V2 CPU Cooler. People have said i should be able to reach 3.8-4GHz
Its my first time overclocking and would like to know if there is anything i should do before installing the cpu (i brought some Arctic Silver 5) and any good guides on how to overclock an 760?

Thanks.
 
The 760 overclocks using the BCLK and multi so for a 4GHz overclock you could use any combination of multiplier and BCLK that gives you the magic 4000MHz. The most common would be 20 x 200. Your board should manage but please understand that it is not a benching system. The board will do the overclock no problem. But ten minutes or an hour to benchmark is one thing, 24/7 is another. At the end of the day temps will be your limiting factor. Keep an eye on them and all should be good.

As to guides the guide which is a sticky in this section is a good place to start. The principle for a X58 system and the P55 chipset are basically the same.
 
Well from your sig, I can see that you've already got an i3 530 @ 4GHz. OCing the i5 760 would basically use the same logic as your i3 but with different volts.
 
Sounds like the i3 is a overclocked bundle if this will be his first time clocking.

The 760 is easy to clock. My first attempt was 200x20 @ 1.275v and it was Linx/Prime stable first go.

it'll be relatively easy for you to achieve a decent overclock mate. there's no guarantee that you'll reach 3.8 or 4, but you should get pretty close with out any problems. i'd be surprised if you couldn't get to 3.2-3.4 just on stock volts. i'm using a gigabyte board too so if you need any help with the bios just give me a shout and i'd be glad to help you if i can
 
Yeah i was wondering if i could use my current OC (which was bought OC'ed) to get an estimate of a starting point, knowing its ok with i3-530 at 4GHz.

CPU-Z shows on my 530 as below.

Multiplier: x 21.0
Bus speed: 191.0 MHz
QPI Link: 4202 MHz
Core Voltage: 1.376 V
 
Ideally, you'd be better to start off below 4GHz and make your way up.

Probably like:

Multiplier: x 18
Bus Speed: 200
Core Voltage: 1.4

From the try increasing the multiplier by a 1. Then if you're still stable once you reach somewhere like 4GHz try lowering the voltage and find your sweet spot.

as lelouch says, you'd be better starting with a lower oc and working up til you become unstable.
you do not wanna start off simply jumping in at the deep end
 
Yeah sorry what i meant was as i know it handled the 530 at 4GHz then i shouldnt be testing from 2.8GHz stock should i? would starting at 3.4GHz be safe?
 
yea 3.4 should be grand to start from. just remember to have at least a temperature monitoring programme running once you begin stress testing the oc. i'd also disable all intel's speedstep malarkey to begin with.
 
Ok so disable EIST/C1E etc and im guessing its not as easy as just changing the 3 settings that lelouch said is it?
 
yup disable them and speedstep, does your ram run at it's stated 1600Mhz with XMP enabled?

it's not actually much more difficult than that. it only becomes 'difficult' when you reach an unstable oc on stock volts
 
CPU-Z is showing:-

DRAM Frequency: 760 MHz
FSB DRAM: 4:16
9 - 9 - 9 - 28 - 86 - 2T

not sure about XMP though.
 
ok hold on, let me have a check on you're ram to see if it supports XMP, be surprised if it didn't tho. can you take a screen shot of what you see when you go into Advanced M.I.T.
 
My i5-760
3.8ghz (19x200)
1.264v in cpuz probably a bit more in the bios.
I did have it 4Ghz stable, but needed a lot more vcore, and I fold on it (maxed out 24/7) so I toned it down because of the temps.
 
Ok think i enabled it, also i was looking in M.I.T but which advanced did you wanna see freq/mem/voltage? also XMP was disabled.
