Change CPU multiplier in windows?

November 1, 2010 at 21:22:40
Specs: Windows XP, Pentium 4 631
I have purchased a pentium 4 631 and wish to overclock it. I have used set fsb but i cannot get it past a certain point without crashing. I need a windows program that allows me to change the cpu multiplier or underclock the ram. I have tried overclocking in the bios but there are no settings, even in advanced mode. My motherboard is gigabyte GA-8S661FXM-775 (rev. 1.x) and I have tried to update the bios with no luck. I get the "BIOS size error please download the 4MB BIOS" error when I try to update with flash879 bundled with the update. There is no setting in the bios protecting the bios from being, no jumpers and no inbuilt bios update software on the bios despite what gigabyte says. I think this might be because I took the motherboard out of a lenovo 3000 j - series.
Any help would be greatly appreciated.

the board isn't good? And why did u purchase pentium 4 cpu? Did u try to check cpu support list? If not then it's your problem, the motherboad u have support core 2 quad/duo. U should buy a cheap pentium dual core e2220. If u can't overclock in bios don't bother overclock in windows. u must have ddr1 400 pc3200 installed.

The motherboard supports the cpu and it runs, i just want to overclock it. It will not run any multi core processors and i only bought the pentium 4 as a short term solution as i plan to buy another motherboard in the near future. And yes i have ddr 400 ram.

The SiS Chipset is very low end and overclocking with software is not recommended, but GigaByte do offer EasyTune5:

The board does have some options for changing settings:

The BIOS Updates appear only to update CPU Support

The dual and quad core cpus are listed as not compatible.

My bios is lenovo 40kt22a if it makes a difference.

I bought the cpu to overclock because of the success stories i have heard with the 631. Someone got it to 8 ghz, however I won't go nearly that far. I plan to get about 4/4.5 ghz as my current running temperature is 17 degrees celcius.

"My bios is lenovo 40kt22a if it makes a difference"

Missed that when I responded earlier. Game over! You cannot overclock that setup.

BTW, 8GHz was accomplished with liquid nitrogen cooling & a highly modified motherboard. It was not a functional system, it was just a "let's see if we can do it" thing.

Therefore if you have a Lenova it is not a retail GigaByte Board, it is customised by Lenova and the BIOS is usually locked down on OEM PC's to stop overclocking.

Research before jumping.....

Ok thanks. I am just surprised i can overclock with set fsb. And yes I know the 8 ghz was obtained with liquid nitrogen and was not planning to go that far.

Or do you know how to underclock ddr, agp and pci without the fsb so i can overclock more?

even with overclocking options available, u won't reach very far (less than 3.5ghz) because of ddr1 400.

I can reach 3.4 ghz. I just need to underclock the ram so i can increase the fsb more.

Is there any way you know of that i could run the ddr 400 at 333 so I have room to overclock?

The P4 architecture is highly inefficient. Ideally, the RAM frequency should be clocked higher than the CPU frequency to help make up for the inefficiency. With an 800MHz FSB CPU, you should be running a 3:4 ratio. In other words, CPU at 200MHz, RAM at 266MHz. You currently have a 1:1 ratio, so your setup is already out of whack. If you lower the RAM to 166MHz (DDR333), the ratio becomes 6:5. That's even worse!

So there is no good way to overclock on this motherboard?

YES you are right it is an OEM Locked Board, if you want to O/C build yourself a PC !
