What P4 do you have?

I'm using a P4 2.0GA and my mobo is d845GEBV2.

Yeah, the said motherboard doesn't allow changes in FSB frequency - as you have observed. So, sadly it is not possible to overclock.

Oh..... so as to say i can't overclock at all ?
any other ways ?
and lastly can anyone suggest a clockable mobo for my P4?

If the mobo doesn't allow FSB changes there is no way to overclock a P4.

How much do you want to spend? List your computer's specs. Escecially, the memory.

hmm.... i'm currently using 1 x 256MB and 1 x 512 MB kingston 266Mhz DDRam.
abt the buget ... i'm using the singapore currency ... so
i will settle with anything that is within $150-200.
But if the mobo is really gd ... i dun mind spending abit more :) 
thanx alot !!!!!

OK, I'm going to assume that means it's a P4 2.0 with 512k cache (aka, the Northwood core). Now, we know your board supports 133MHz bus clock (aka 533MHz FSB). So you CAN try overclocking it to 2666MHz on your board buy raising the bus speed ON THE CPU from 100MHz (400) to 133MHz (533). If you have an address for me to send "Crashman's Hardware Overclocking Guide", PM me and I'll send it to you. This type of overclocking requires the minipulation of pins.

It is possible, because he has a 400 bus CPU. All he needs to do is break off pin BSEL0 from the CPU to make the motherboard detect it as a P4 2.66/533. Also, shorting pins VID3 to VSS will raise his core voltage from 1.50v to 1.70v.

Hey, here's some news for you: I'm thinking of writing an article on adding a 8-switch microswitch to one of these boards so you can do those settings and reverse them easily on any Intel board with many 400-bus processors. If you wanted to send me a board I'd do the mods for free. This could be my chance to break into journalism.

Well, now that is some valuable information. I say: go for it.:D

I suggest that anyone who wants to attempt CPU modification varify that CPU's ability to run at the higher bus speed first (on a board that allows overclocking) As for modifying the board to use DIP switches instead of CPU bus speed/vcore detection pins, well at least you can set the CPU back to stock.

haha .. it will be great if u r 2 do it 4 free ... but i cann't live without my comp running !!!! Think of getting another board to save all the trouble.Any boards to reccomend for my P4 2.0AGhz?

Abit BH7 is gaining praise as an excellent overclocking board. Cost under $100.
April 21, 2003 1:53:14 PM

Thanx for the info .... btw .. ur $100+ is in wat currency ?
Any other choices ???
April 21, 2003 2:01:07 PM

- US dollars.

- I can't think of any other motherboards in that class and price range that would cause me to look past BH7.

Looks like if i want to overclock i have to open up my casing and do the job.I'm very much interested in the guide.Pls mail it to me.

My e-mail is midnightblues79@hotmail.com
Thanx alot !!!

Thanx alot. I receive it the mail.But i think i will not overclock it now as i will have nothing to fall back on if I fail! Think i will experiment it when i get another mobo.
Other than the mobo from abit,is there any other good and stable mobo?

Right. It would be reversable of course if you modified the board to turn that socket pin on and off with a switch.

Right now the fastest boards have the Intel 875P chipset which was introduced about a week ago. These use Dual Channel DDR and new memory tricks to make the thing far faster than previous boards. Abit even advertises that theirs will always be stable to at least "1 gigahertz bus speed", which is 250MHz, aka QDR1000. Compared to your QDR400 bus of course, it's 250% higher.
