Soft Overclocking

[Ian]

Is it still possible to soft overclock a CPU (P4) on an Intel Chipset?

I can't change anything in my BIOS, but I wouldn't mind ramping it up a bit Its a bog standard 3.4 HT P4 - and they clock fairly well apparently.

Not going to change the motherboard for a few extra Mhz, but I wouldn't mind seeing what it can do

Yeah you can, but it depends on the motherboard...

You need to make sure you lock the AGP/PCI bus to 66/33 respectivly (at least thats what it is on mine, but yours could be PCIe?)

I would definatly reccomend using BIOS if at all possible... soft overclocking is a bit sketchy...

Give it a go

What is "soft overclocking"

 

[ChristopherP]

overclocking from windows instead of BIOS

 

[Me__2001]

you might be able to if you can find something compatible with your motherboard

Can you explain a bit more on how it is done, you have got me interested

Use Bios

 

[PotGuy]

you can overclock gfx cards by programs that run in windows, like the ati tool or whatever it is

 

[ChristopherP]

Yeah - thats the way to overclock graphics.

For CPU its best to use BIOS - its much more stable.

OCing my P4 in BIOS, fryed my motherboard (https://www.pcreview.co.uk/forums/thread-2442178.php). Probabally should have used better cooling though I think.

I'll still try it again though when i find a good board again.

heh - fried from a 115 mhz increase was it worth it?

 

[ChristopherP]

The trick is to increase by 3 or 4 steps of the fsb in BIOS, then save and exit, see if windows boots. If it does? run Prime95 for half an hour or so. If it dosent error or crash, repeat from the beginning

Thats the way to a stable overclock

Prior to that though I have had it running at 3.6GHz and 3.75GHz, which might have caused underlying damage. It would run stable up to about 3.4GHz. Still, i think it's lucky only the mobo went and not the CPU and mem too

Try Clockgen

If your chipset is supported, you can push the fsb within Windows until it chokes and either freezes or reboots.

Then go down a notch or two, and, if possible, change fsb in Bios.

If you can't change in Bios, changing fsb within Windows using Clockgen will stay at that setting until you reboot.

It's a good tool for seeing how far you can take your system, I've used it a lot.

I can only get my Socket A XP3200 to 2.4Ghz (stock speed 2.2Ghz), I think my Corsair Value Select RAM is the weak point. Good solid stable memory, but a bit crap at overclocking.
