Overclocked Athlon xp 2500+ to 3200+

[Wraithwrecker]

Hi, I just upgraded my system to A7n8x (nforce2), Athlon xp 2500+, 256mb pc 2700 ram.
I overclocked it to FSB = 200mhz and Multiplier to 11* (so 2200MHz) running at teh normal core voltage (1.65V) , which is all fine, with a temp of about 46 degrees C (from 42 degrees before) . The thing is that my computer thinks it is a 3200+, when i look in System Properties!! Is this normal?
I have read about AMD labelling better processors as worse ones when they have underproduced a certain type. Did i get lucky, and get one???
If so can i overclock it further? At wHat temp do things start to get dangerous?

i think you describe the prob with the internal and external frequency...

p.e.:

I have a JIHUB Athlon (1700+) in my computer it now is an internal 2.34 Ghz but regarding the external it's a 2900 Ghz!!!!! And it's only about 46°C (not kidding) so I just made a 2,9 out of a 1,7...

So try SiSoft Sandra 2003 and see the reference CPUs in order to find out...

Dunno if you can push the crashing border further but try doing it... But if you do try doing it slowly and always make a high performance test before labelling it OK... It took me 2 days to find out my 2.9 border... if I go higher my system crashes every 2 hours... (faster with performance-eating games or stuff like that)

In any case be careful and also check the frequency your cooler supports...

Have fun then

Thanks for the reply
I used Sisoft sandra and found my performance was v similar to a 3000+, so i think i'll label it at that for the moment!
how would i check the frequency the cooler supports? It is just the boxed cooler from AMD, so is not so brilliant
By the way nice work with your pc

If you're running at 2.2G and 200fsb, then for all intents and puposes it's a 3200+. That's called overclocking. Excellent overclock for stock voltage.

Now you have to test it, to see if it's stable. If not then you increase voltages.

if you don't know the freaquency of the cooler you'll always have to watch the temperature when you run on maximum performance level in the beginning... If it stays quite cool it's still ok but if that doesn't do you'll need a new cooling system/cooler...

My PC was 100% stable, but changed setting in my bios to Aggressive, and crashed the machine, had to take it into the pc shop this morning. THought i had burnt up my processor, parents obviously mob mad!!! However they just replaced the RAM and it worked, changed settings down and everything is fine. It seems my RAM just couldnt handle the 200mhz FSB and "Aggressive"!

When you changed your BIOS setting to "Aggressive", you changed your RAM timings to a lower timing, and your RAM couldn't handle the lower timings. All you needed to do is reset the BIOS, your RAM didn't need to be replaced. Well, let me say that it shouldn't have needed to been replaced.

By the way c6ke, an Athlon XP 1700+ runs at 1.47GHZ, not 1.7. Also, what are you talking about CPU external speed??? The only external speed I know is the FrontSideBusSpeed.

Your CPU speed is measured by the FSB * Multiplier= Frequency.

How would one reset the bios?? I didnt replace the RAM, just put in a different RAM, to change the Bios back, which allowed us to put the old RAM back, and all was sorted.

Almost all motherboards have a set of jumpers to "clear CMOS." Alternatively, you can pull out the CMOS battery for several minutes (make sure your PC's power cord is unplugged, otherwise just pulling the battery may not work as most modern mobos will still be powered e.g., Wake-on-LAN type features).

Either method will clear CMOS, resetting BIOS settings to a default or safe mode. Replace the "Clear CMOS" jumpers to their normal position/re-install CMOS battery and you are ready to tweak again.

I agree, the 2.5 Barton will run quite happily as a 3.2 with default cpu voltage. Mine does as do most 2.5 Bartons - Same core as the 3.2.

The a7n8x supports dual channel ram (NOT the x-x though), stick in a couple of 3200's and watch that baby fly

If your running a boxed hsf then run 3dmark for a while and see what your temps get upto. I had to get a better cooler as under load the temps went upto 60c but dropped to 46c normal. Got a coolermaster CP5-8JD1F-0L ? hsf from EBuyer for £12 and now running at 39.5c under 100% load running FaD dc client.

Now thats what you call a cheap upgrade - 2.5 to 3.2 for 'next to nothing'.
