Just need a bit of help, as im new to overclocking and i was wondering , what i would need to change in the bios to get my i7 to 3.0ghz. What needs to be enabled at disabled.Would someone be able to post a rough screenshot of what settings would have to be used thanks.

Btw , will 3.0ghz be ok with a stock cooler and 6 120mm case fans.?Or can i go further?

Cheers
 
Have you got your pc specs so people can look and give answers quickly for you, also my gigabyte motherboard has a windows utility that does overclocking .

I easily run mine at 3.1 ghz in the past.

To get to 3ghz you would change very little.

You haven't said what MB you have, so cant give you specific settings.

In any case all you need to do is raise BCLK to 150mhz.
It will be set to auto, change to manual and set 150.
Leave all the settings unchanged except the BCLK.
Save and exit bios.

You may also reduce the vcore to get the temps under control but this will need to be done gradually testing that you are still stable.

20x150 =3000
21x150 3150 if you have turbo enabled.

Test with prime95 or linx and see what temps you get up to.
Suggest you get a larger heatsink before going for 4ghz :)

You will have speedstep enabled as default so dont be alarmed if you see the CPU speed reported low, it will go to full speed when you put some load on the CPU.

Use coretemp or realtemp, they will monitor the temps obviously, but also will show you speedstep altering the CPU clock as you run the testing programs prime95 or similar.

If you are talking about Easytune its not that great. I was advised to always use the BIOS when overclocking as easytune is common resulting in blue screens or so I'm told.
 
Always use the bios for any overclocking and never software as it can really mess things up. For a 3.1GHz overclock you'd hardly have to change anything apart from up the bclk a touch. Although i would still be tempted to input my own volts and multis, etc as most motherboard's auto function can uneccessarily over volt the cpu (and other components) causing higher temps.
 
Thanks guys, your ever so helpfull. Very speedy reply.

The spec of my new pc will be as follows:
intel i7 920 2.66ghz D0.(Stock Heatsink)
Asus P6T SE Intel X58
Ocz 6GB 1600mhz DDR3 Triple channel
XFX Ati 5850.
NZXT Gamma Budget case(with 6 120mm Fans).

So with this setup what would i have to alter in the bios for a stable cool temp oc to 3.0Ghz?
Thanks.






Btw whats
 
You will probably need to set voltages manually because left on auto even at 3ghz it will probably raise the voltages, you shouldnt need to raise any voltages for 3ghz though.
 
oh sorry never noticed question BCLK which stands for base clock can be raised to 150mhz with outneeding to worry about raising voltages (make sure the bios doesent raise them on its own accord set them to manual but keep them at the same figure) etc
thats about it really you only need to worry about changing the RAM's clock and raising voltages when you are raising it hight but 3ghz is vey safe and simple
NOTE: just noticed PCZ has a beautiful explanation higher up in the thread

You should really buy a better cooler, the stock cooler will limit your temps and overclock.

If 3ghz is all you want then try the following settings:

AI overclock - manual

CPU ratio - 15x
BCLK frequency - 200
PCIE frequency - 100
DRAM frequency - 1600 (you may need to set your ram timings, e.g. 8-8-8-24)
UCLK frequency - 3200
QPI frequency - 7200

Load-line calibration - enabled

CPU Voltage - 1.0-1.2v
DRAM voltage - 1.65v
QPI/DRAM core voltage- 1.2-1.35V
CPU PLL voltage - 1.8v
(NB)IOH voltage - 1.13V
IOH PCIE voltage - 1.5v
(SB)ICH voltage- 1.11V
ICH PCIE voltage - 1.5v

CPU spread spectrum - disabled
PCIE spectrum - disabled

I usually just keep speedstep etc.. all enabled, but if you have problems you can disable them.

Test with Prime95 (keep temps under 85) and use Realtemp and CPU-Z.
 
Thnaks for the Info matey:)
Ive acually overclocked it now to 3.1ghz and 1600mhz on the memory:)
Now heres the thing, would 1.1v be enough, becuase on prime 95 100% load i get temps of 76 degress after 2hrs?Thats runing at 1.2v.


so will lowering the voltage give lower temps?


also if i use speedstep it becomes instable. Will i lose a lot of performance with this setting turned off in the bios??

also what is the maxiumum temp u would suggest for a stock heatsink on a 920.

wil 80degreess ruin the chip?
 
speedstep only offers a power scale, when under light use it ramps the cpu down, when the cpu is under normal or heavy load it ramps it back up, disabling it wont effect you to be honest so leave it off.
80 degrees wont ruin it on load but the cooler the better, and always try and get the vcore down as low as possible to reduce heat and prolong the life of the chip.

Every CPU is different and you can't tell how much voltage it will need at a certain overclock, but you could probably run the voltage lower. You just need to try and find the lowest possible voltage for your chosen overclock.

so will lowering the voltage give lower temps? Not always, but it usually helps.

also if i use speedstep it becomes instable. Will i lose a lot of performance with this setting turned off in the bios?? Speedstep is an energey saving feature, so you won't lose any performance.

also what is the maxiumum temp u would suggest for a stock heatsink on a 920. Try and keep temps under 85 while stress testing and you should be fine, but personally i would buy a better cooler.

wil 80degreess ruin the chip? No, not for load. If you're getting that with Prime95, then under normal usage the temps should never come near that.

You really need to get rid of the stock cooler and get an aftermarket one, The Coggage TRUE Spirit is a great cooler, I have one myself.
 
For a 3.0 GHtz OC, stock cooler is fine. In fact, up to 3.2 GHtz, it's fine even on auto settings. Anything beyond that, the OP will need a good aftermarket CPU cooler.
