Default Overclocking an Athlon XP 2500+

BTW good article on Sempron vs. Athlon XP. So your saying in general the Athlon XP should be faster than the Sempron and if I understand correctly these CPUs can be OC by adjusting the FSB to a higher value but resulting in a higher operating temperature, but still well within normal operating temps? Also for the most part the operation voltage of the CPU is not effected that much. This means I can still use my stock power supply? I have to read up on this procedure can you recommend any posts? Many thanks...

Increasing the FSB is the way to overclock these babies, but it will of course also increase the memory and NB speed, so any of these components can be the limiting factor to how high you can go.

Default First timer OC'ing an Athlon XP 2500

Olle P thanks for the tip. Currently I'm reading this guide... http://www.overclock.net/amd-general...ml#post3559197 I have to read up more on this subject can you recommend any posts especially relating to Socket A (462)? In general I dont want to burn up my PC so basically I want to tweak it so it will be a little more efficient. To use an analogy its like when you buy tires for a SUV too big no go, but just one size bigger your golden. But I still need more info on this subject on how-to OC my AMD chip. Many thanks...

There's little risk of that, since that CPU can handle close to 90C. The cooling probably is the limiting factor though.

Overclocking the FSB by a few MHz should be no sweat, provided you've cleaned the heatsinks from dust and have a fair amount of ventilation in the case.
If you want to overclock enough to notice the difference you'll need considerably better than the stock cooling. Problem is that unless you already have good cooling it will cost about as much to prepare the computer for overclocking as it cost to replace the motherboard, CPU and RAM with something considerably faster!

The athlon if it hits 60 it throttles. So keep it under 60 otherwise your oc will be reduced to nothing with a cpu in thermal throttle

Are you really sure about that?
I know my Palomino would automatically shut down (completely) at 85C, but it would certainly run at full speed up to that temperature.
And I don't think there's any thermal throttling involved with any other of the CPUs for sockets A, 754 or 939 either.

Cheers

I'm pretty certain there was some sort of thermal throttling in the Athlon 64 generation- no clue about the XP generation.

It's been quite some time since I ran anything on my old Athlon 64 3200, but I do remember the temperature hitting some sort of cap around 50-60C.

If your board supports an XP 3200+ 2.2 that would be the easiest change. XP-M preferred.
Prices tend to be rediculous however,
There are also aftermarket Socket A coolers floating around, new and used, how to tell good from bad, shrug, I find the reviews from back when, if available, contradictory.
