Oc P4

[MaxLG]

Hello, I would like to OC a pentium 4, which with a little bit of effort would go super well.
First problem, it's locked, ok no problem, I lower the PLL to OC the FSB.
It's CY2484100 I think, and it's not in the PLL list of SetFSB or in Clockgen.

I've seen that setfsb has a creator mode, is it very complicated?

What ideas do you have so that I can increase a few Mhz more?

A Pentium 4 won't give you much if you overclock it, and depending on the model, you'll have to invest in a good heatsink, plus they're real ovens and more so now in summer, the issue of clockgen or setfsb not working. I never use software to perform OC, what I look at first is the board that lets me modify those values that as I say you won't notice a very high performance difference when it comes to that old architecture, I put a Pentium4 at 3ghz up to 3.5ghz and I didn't notice much improvement. If you tell us at least what model of board, and Pentium 4 you have and it itches, show them here so we can help you.

I don't want much difference, just that it goes a little better. And I'm not going to spend on a disipdor when I'm going to buy a much better PC soon and it already costs me a fortune.
The processor is a P4 630, and the motherboard is a 0yc523, from DELL, with an i945P chipset.

From the BIOS it doesn't give me any.opción.
It's to squeeze out the last days of vacation that I will be with this PC

If the motherboard came from a PC assembled by a major brand, it is likely that the BIOS does not have the menus to modify the base clock or other options for overclocking.

I already know that, that's why I use the setfsb that worked well for me until I found out that this pc has a pll that doesn't show up in the setfsb, the question was if there is any way with any program or trick to increase it by a few Mhz.

It's useless, the difference you'll notice is minimal and more so now in the summer, if you don't improve the cooling and that board, you won't be able to scrape many more Mhz and if you're going to get 100-200mhz just to say something, you won't notice it just like that.

It is a difficult and unprofitable endeavor. If it is for the luxury of seeing it rise, the disappointment will be greater for the impossibility. If it is for utility, above you have the steps to follow, and you will still achieve very little improvement.

Best regards

@Sylver:

If it's because of the luxury of seeing it go up, the disappointment will be greater because of the impossibility.

So is it impossible with this PLL?

You can try selecting another PLL from the list to see if it has the same parameters and increases what it should, there is no danger as long as you look carefully at what it really serves and try to increase one or two units as a check, but I only tell you this to clear up any doubts so don't rub your hands yet.

Then from what I see you can do pinmod to the PLL chip which is delicate and also may only work for some fixed values.
There is also something about a modified bios, but I don't know if there will be something done for you and doing it yourself is a lot of work.
And creating a profile by hand for your PLL in clockgen/setcpu will not be easy either and will require a lot of research.

If you are looking for oc for practical reasons and you will have a new machine in "soon" I don't see the point in getting into such tasks, it would only make sense to do it for hobby and to learn new things, and with plenty of time to dedicate to it.

I don't know how "soon" you are missing for the new pc but in your place I wouldn't get my head so hot if I were missing a few months.

[Sylver]

Impossible no… I would say, improbable. A lot of effort to get just a few mhz. Besides, I have one of those beasts and with the stock frequency at idle it touches 70º with a custom cooler... There's not much you can do about it.
