Dumb Question here

[KingNothing36]

Hey all, new computer builder here, sorry for asking a dumb question. But...i wam going to be using a Barton 2500 CPU with an nForce2 mobo in my upcoming computer, and I was wondering...what exaclt do you have to do to overclock? I know you change a few settings, I think one is like the FSB, which is sort of a multiplier...but where do you change that?

I may have more stupid questions, sorry to bother you more experienced people.

Buy the mobile barton 2400+, and the multiplier on most nforce2 mobos are adjusted through bios.

Why? Sorry, but I've gotten a thousand opinions on what processor to use...i mean, i would consider everything but right now the barton 2500 jsut seems to be way out there. could you tell me why i should get the 2400+ instead?

Also, could you give me some tips on using both of them? I am using stock heatsink, with 4 fans and a thermal monitor/fan control.

notice he said <b>M</b>
because Mobile Barton 2400+ can be easily overclock to a much higher speed, which a normal barton 2500+ can't reach

Sorry...but why is one called mobile and one not called mobile?

Mobile chips run at 1.45Vcore instead of the default 1.65V on desktop chips, they overclock better than desktop chips.

With the Barton core xp2500+ the multiplier is locked at 11. In order to overclock you have to raise the front-side bus from 166x2 to 200x2 if possible. That means using PC3200 or DDR-400 ram instead of the standard PC2700 or DDR-333. If you can get your FSB to 200, you will raise the chip speed to 2.2ghz or an effective XP3200+ speed. The XP Mobile chips have an unlocked multiplier. Now in addition to raising your FSB, you can jump your multiplier up to 12.5 or so. 12.5x200=2.5ghz, or XP3600+. The Mobile XP's also run cooler and take less CPU core voltage to get there. It's kind of a no-brainer since not all socket A motherboards will guarantee a stable 200mhz FSB. The Mobile is the way to go!

Are there any downsides to using a mobile rather than desktop?

 

[scottchen]

except for the slight higher cost, they're a much better overclockers.

Well, on NewEgg the 2400 M is cheaper than the 2500, so that's pretty good. Does the mobile have a heatsink or anything? Does it need one? Howabout installation..is it different from a normal processor?

 

[scottchen]

I believe they're OEM so buy yourself a Vantec Aeroflow, it's exactly the same as the desktop processor, except it's running at lower vcore and capable of handling higher temperatures.

I read somewhere that the VID pin definitions are different for mobile and desktop processors, resulting in slightly higher the stock voltage when you put the mobile on a desktop board. All the better for overclocking!
