yeah, but i still want to try and see how far i can go with what i have right now.

it would be great if someone could get back to me about the right clock generator setting because I don't see the chip on the setfsb website

Why don't you return the board and get something that is actually compatible with that CPU?

I have to agree. Don't waste your time. I mean, I'm all for tinkering for the sake of it, but you're still going to have a 1.xGHz (!) underclocked Pentium 4. That's no solution. Even if you raise the FSB, you're not getting close to stock, let alone overclocking (because it is far underclocked right now). I doubt that Northbridge chipset is going much higher, and it probably has no voltage control and no fan on it. You might get 100MHz-200Mhz give or take, but who knows? Those Pentium 4s were bandwidth starved. At 100MHz FSB, it's going to be terrible.

because i bought it used on ebay and its unrefundable.
and im okay with it having 1.x ghz currently its running fluidly on winxp.
as long as i can get about 200 MHz more out of it i am fully pleased. i dont want to oc it to stock speed or something.

It not overclocking atm, it's underclocked.

But it it's for browsing, it'll be be at about 1.6Ghz... Even tho that's 1Ghz below stock.
I'm not sure since I've only worked with a few Intel setups, there is a tool from Intel which allows FSB control... Depending on the chipset you're using...

Well, the chipset does support 533MHz FSB, and is running at 400MHz FSB now. The CPU is a 2.6GHz CPU running at 1.3GHz.

This is happening because, as was said, it's an 800MHz FSB CPU in a board that doesn't support it. When this happens, Intel has it clock down to 400MHz FSB. Your board/chipset can do 533MHz FSB though, so theoretically, you can raise it to that and be done with it. This would give you a 1.73GHz clock speed.

What you need to do, exactly, I wouldn't know unfortunately.

should be good.. as long as your RAM can handle the OC.. with no RAM divider to change, your gonna be pushing memory to try to make 200FSB.. 

 

**really wont help much anyway, as the mobo is defaulting to a lower CPU multi [which will not change].. so your stuck with x13.. regardless of how much FSB you add. You have to get to 200FSB to be at stock.. as said, the mobo and CPU should be fine to run that... RAM is different story though, as you will be relying on what the mobo chooses to run timings at what ever speed....

 

*I run a 2.66 P4 mobile in a desktop rig.. does pretty much the exact thing, as the mobo is not made for mobile CPU's.. but does support 800FSB... it defaults my CPU multi to 12x as well..

 

 Heres an OC to stock clocks.. with all stock voltage. Only FSB and mem increased.
