Hello i am new to the forum,

I am not a big overclocker nor have i been doing it for very long. With my last system i overclocked it just a tiny bit to get a bit extra out of it but with my new system i thought i would go a bit thurther.

Here is a screen of how far i have got so far:

My first few questions:

Have i got anything completely wrong here?

Is my Core voltage too high?

Should i put my multiplier upto x 10.5? i get very OCD over things and i wanted to get everything in ince numbers =/

I have my ram overclocked at 500Mhz each which is 100Mhz over what they are ment to be and this is stable but they run at 1.8v and thats what they are ment to be at. not 2.2v but i put them up 0.2v. would this be fine?

I know i am new here but i will try to offer support to other people around here so that you will do the same for me.

Thank you

Have you ran Prime95, LinX or IBT to check whether this is stable or not?

I'd suggest that you only o/c one thing at a time, drop your RAM multi back so that your running at or below your RAM's spec, and then test your CPU overclock with LinX/IBT or Prime95 (at least 20 passes of IBT/LinX using all available RAM, and for Prime most folk say 8 hours is needed), then once you're sure the CPU overclock is stable, then you can knock the RAM multi back up and test for stability again.
 
If you want to quickly test your O/C I personally recommend LinX or Intel Burn Test, as these are much quicker than Prime, however, there's been times where my system has successfully passed LinX, but it fails Prime after 2 hours..

However, these stability tests tend to put a hell of a lot more stress onto your components than pretty much anything you would do if you're only a casual PC user, so you could just bypass the stress testing completely, and then use your day to day PC usage as a means of testing your o/c to see whether it is stable or not, it's your call at the end of the day.

Regarding settings, I'm not familiar with Core 2 overclocking, but if you are aiming for a specific overclock, then you use any means necessary to get there..

I hope that helps.
 
Use the max multi, so u don't need so much fsb, also try where possible to run your memory at stock speeds, you should only have to run the memory overclocked when using high FSB's (which 400 is'nt).

Id also suggest turning intel speed step off as well, as u should be able to get that clock on a much lower vcore then its currently at too.
 
Ok i ran IBT and it got a bluescreen after a few seconds. i put all the settings back to default and IBT ran fine.

Yeah i am going to keep my ram at stock speeds. How much bus speed should i put it at with standard voltages? the default is 266.

Thanks

each cpu is different, your best thing to do is to up the fsb by 5 each time, do a quick ibt run, each time and once it fails you know thats to much, so knock it back abit.

sadly overclocking is a pain stacking thing to do, well to be done properly that is.

Just try and keep ur memory divider, so that the memory is running @800mhz.
 
Ok thanks.

I installed my motherboard software from gigabyte called easy tune and i can change the FSB in the OS without rebooting. I am going to put it up every 5mhz then run IBT again.

I underclocked my ram as you can only change that in the BIOS so it wont go over 800Mhz.

Thanks for the advice. its been great.

yup, once it won't do anything over a certain point, that is when u up the vcore a notch or 2.

Then its testing again, untill it becomes unstable, and so on and on, untill u reach ur goal, or heat becomes an issue.
 
That all depends on what increments ur mobo allows, by notches i mean by very little each time.

Not say from 1.2, to 1.3 or 1.4.

Like this 1.25, then try 1.275 and so on if you know what i mean, add vcore little by little.

Hery Dannylivi,

looks good to me, get some stability testing done (Gaming, Prime95, IBT etc) and keep pushing it . . . 1.472vCore should be enough to max the chips MHz!:D



The really nice thing about these newer 2MB Wolfdales is they don't seem to have any FSB limitation, got one running at 500MHz-FSB which is respectable for a budget chip, didn't get enough tweaking time though before I sold the board and chip so not sure if I could have got it 24 hour prime 95 stable or not, failed after 20 hours! :p

 
Thank you guys, this fourm really is amazing and you have been very helpful.

I shall wack the vcore back up to 1.472 and then gradually up the FSB untill it get unstable on IBT.

Just keep an eye on your temps though, thats the main issue when running that high a vcore, i know my e8400 gets rather toasty running 4.5ghz @ 1.5v lmao..

But yeh keep going and let us know how it goes.
 
How high is the maximun recomended temp because my mobo sets an alarm when the CPU goes over 70c and it goes at 71c when i set IBT to max.

Too cool it i need to drop my vcore right?

Thanks

~Danny
 
If you look here http://ark.intel.com/Product.aspx?id=41493 the Tcase max is 74.1 for the cpu temp. Thats tha max overall cpu temp, the cores can and will go a lot higher.

So your still under safe limits, Nothing and i mean absolutly nothing will push your cpu to the extent that IBT does, both stress wise and heat wise.

And yeh lowering the vcore will reduce the heat output.

You should be able to adjust that value in the BIOS . . .

I aim for 55°C Prime Load - 65°C IBT Load because I'm an overcooler but if push comes to shove and extra vCore is needed to get the clock right then 65°C Prime Load and 75°C IBT load . . . :)

Remembering that IBT is a Worst-Case-Scenario Diagnostic so the temps is produces are not likely possible in actual real world usage although I still like it to pass a 50 loop run without errors. I find Prime95 quite realistic in terms of load temps with encoding and some gaming loading the cores to a similar degree . . . :cool:
 
Yeah i will up the value in the BIOS now. So how do you find out the CPU overall temp? When doing the IBT the cores reached about 75C max.

Ok well i only want to push it so IBT does it fine i wouldnt want to push it any further.

For overal Cpu temp i use Hwmonitor http://www.cpuid.com/hwmonitor.php

If that 75 was ur cores, then no probs, still head room to go.

As wayne said, day to day u will never hit these temps ever, my gaming temps are 40c, prime 95 temps 45-50, ibt 55-60c, these are all overal cpu temps.

Cores well gaming never go above 38 (can't actully tell what it is as stuck idle sensor on cores), prime max they hit are 45c and ibt shoots that upto like 60c on cores.

So as u can see, ibt really really heats things up.
