i just overclocked my i7 to 4.00ghz, and i get around 45-50c at idle!, and after running prime 95 for a few minutes to he cpu was at around 72c!.

is this right, i have a megahalems with 1 120mm fan, but the fan is only running at 1200rpm, this fan says it can go to 1400rpm, how can i make it spin faster?

thanks
 
You need to let it run for more than a few minutes for those load temps to level out, they will probably get a little higher than that yet, these chips are generally good right up to 88c, though lower temps are better of course.

I'd guess that with 1 fan on the Megahalems your load temps will sit around 76 to 80c..

If you stick another fan on there that will help shave an extra few c off the temps as well..
 
It all depends on your chip mate, some chips will do 4GHz with as little as 1.18v, where others need as much as 1.35v.

::edit::

1.3v isn't the max amount of vCore these chips can take, 1.55v is the max according to the Intel spec sheet:

Though, generally speaking, most 920's will do 4GHz with 1.3v, so this is a good starting point for overclocking, but it's definitely not the maximum that you can push..

LoL!! :D

Start at 1.3v, then test for stability, if it passes 20 runs of Intel Burn Test, or LinX (I prefer to use LinX) using all available RAM, then you can try lowering vCore by 1 increment in the BIOS, and then test again, if it's still stable, repeat this process, and keep doing so until the system becomes unstable. Once it starts becoming unstable, just go back into the BIOS, and then put the vCore back up to the last known stable setting..

Though there are other voltages that you might need to play with in order to get your system stable, QPI/Vtt is the other main voltage that usually needs to be tweaked, but there is no harm in leaving the other voltages on auto (except vDIMM, set this to 1.64v), and seeing whether your rig is stable just by altering the vCore.

Which Bclk are you going for anyway?

Are you aiming for 200x20, or 191x21?

191x21 is considerably easier to get stable than 200x20, so it's probably best if you aim for that first, remember that Turbo Boost Tech needs to be enabled on these Gigabyte boards to enable to 21x multiplier.

im am using 200x20
 
i have a new problem, my ram runs default at 1600mhz, i clocked it to 1200mhz, because of this article, he said that the ram could stop windows from booting. but no when i put it back up to 1600mhz, the PC doesn't boot. i don't know what the problem is?
 
The problem is that you've set a bsck of 200 without bothering to find out anything whatsoever about what you're doing. So you have no idea what the other settings should be, and no idea how to work out what they should be. So it's not stable.

can you stop abusing all of my threads, thanks
 
Your last thread had exactly the same issue as this one. If you are unwilling to do any research you will not understand anything, and will evidently continue asking unanswerable questions.

Your fan will run at full speed if you connect it to the psu instead of to the motherboard, or if you turn off speed control in the motherboard. That you asked how to speed up the fan to counter high temperatures when running 1.5V vcore does not suggest you know what you're doing.

As I said in the last thread, if you are unwilling to read anything your results will be poor.

i look on the internet and ask questions here, this is an overclocking forum isnt it, or am i mistaken..
 
As mentioned, if you do a bit of research on overclocking the particular components you have it really helps, the i7 is a pretty easy setup to overclock to 4ghz once you get your head round the various settings. Id suggest starting with the 21x multi as its easier to get stable using this, start from a low clock, say 3.0-3.2ghz and work from there, test with linx for stability and use this as a stable base to push higher, also write down a list of settings and changes you make in bios along the way.

ok thanks
 
It is indeed, and I would be thrilled to help you in your endeavours. However it is not practical, or even possible, to do so if you will not take the time to learn the basics yourself. At the very least you should find someone with similar hardware to you and look at the numbers they've set. Not one of them will be using anything like 1.5V for 4ghz, for reasons that should be obvious to anyone who has read a faq.

The lazy approach is to copy the settings from someone who has done the hard work for their system, then tweak them to get it stable for your hardware. However for this to work you still need to spend the time googling the various words found in the bios, and reading a thread on stability testing.

Perhaps you are correct that I could be more helpful, or at least more tolerent of your reluctance to use Google. As an apology. these are the settings I use for 4.0ghz using a ud5, 920, 6gb of 1600mhz ram. These are unlikely to be stable for you, you *will* need to stability test and tweak the settings.

The source is the thread found here which is a reasonably detailed record of how I am attempting to overclock my system. I hope you read through it, as it is intended to be helpful. I apologise for the erratic formatting, I can't turn it into a guide until I've worked out some freezing which I think is turbo related.

thanks a lot for that, i am a newb with computers, i have only really become intersted in the past year. i will try to use google more.
