Mobile Athlon XP's FSB

[Markolc1]

Reading AMD's website it shows that their Athlon XP Mobile series is available at 200 or 266MHZ FSB. Now does that mean they have specific 200fsb and 266fsb versions, or does the chip just work with with either FSB is available. I want to possibly upgrade my HP Pavilion XH485 Notebook with an Athlon 4 1ghz processor and add possibly a new Athlon XP mobile processor to the notebook. Does anyone know If i'd need a BIOS upgrade or if the laptop will take the upgrade without anything special done to it? I use 512MB of PC133 SDRAM in the lappy, so it is definately 200 FSB. But please clear up the 200/266 thing. Thanks

Hmm you might be able to actually upgrade your Athlon. Almost all notebooks use the standard socket A and you just need to dissasemble your notebook and then pop in another chip. I do believe all AthlonXP mobiles .13micron run a 266 fsb. I dont think you're laptop BIOS would support the 266fsb.

On AMDs website it states the Mobile Athlon XPs run 266 or 200. I just wanna know if ther're specific chips that run only 266 or only 200.

the early ones used the 200fsb because of the platform / power consumption these were usually the athlon4, which were 0.18micron chips. Once the move to 0.13 occured the 266mhz fsb started to become more used - but some older 0.18 chips were used on the newer platform.

So do you think I can take a desktop Athlon XP like a XP1900+ .18 and use it since it supports 200mhz? I know it won't run at the advertised speed, but at 200 MHZ it should be around 1353MHZ right? The Difference between the Athlon Mobile and Desktop is just the Powernow, right?

I would suggest going for a tbred rather than an athlon xp, amd used their fastest chips but underclocked for the laptop. a 2200xp would be good, or any low grade tbred b revision

The problem now is I don't know if the laptop MB or BIOS will support the voltage or multiplier.

 

[Mingon]

the if you get an 1800 tbred it uses a 11.5 multiplier and 1.5vcore - the athlon 4 uses 1.3vcore iirc

Let's say I have a laptop with an Mobile AMD Athlon XP 1500 processor, and let's say I'll want to put in a faster Tbred in the future. I would be able to do that without a problem, right?
