I was just woundering how hot can a processor get b4 it starts to mess up. The highest my pc has gotten was 37c. If i overclock to 3200 from a 2500 how much will my temp get effected??
-
Ive heard Barton's run hot as it is. Not sure about overclocking. Im sure someone who actually knows somethingabout this will post soon.
-
You can over clock it. Just keep an eye on temp to make sure it's not over heating to the point of "melt down". Not sure what actual temperature it would be, but a day over clocking would tell you easily what the average is.

Im have decided to overclock it to a 2800. Now im just reading about the multiplyer to set it at. I f any \body knows plaese tell me

Since you are running PC3200 memory (DDR400) you can increase the front side bus speed on that 2500+ from the stock 166 MHz (333 MHz effective) up to 200 MHz (400 MHz effective). At a 200 MHz FSB clockrate the 2500+ will be running at 2.2GHz true clockspeed, which is the same as the 3200+. (The 3200+ Athlon XP runs at 2.2 GHz on a 200 MHz DDR bus.) Just about every newer production 2500+ out there can do this without a problem.
Unless you have to increase the CPU voltage, your overclocked CPU will dissipate the same amount of power as a normal 3200+ would. Your current temp of 37C is not high for a 2500+. I would expect to see that temperature increase to around 42C - 45C at a 2.2GHz clockspeed. I normally look for a CPU temperature of no more than 55C under full load with Athlon XPs. I have seen systems with CPU temperatures slightly above 60C run without problems, but I would not be comfortable with that. (CPU temperatures also tend to climb with time due to dust build up etc.) Barton core Athlon XPs actually run cooler than Throughbred core Athlon XPs did. The die surface area is significantly larger on the Barton, which seems to make a difference in getting the heat away from the CPU faster. They certainly dissipate much less power than Prescott core P4s. The exact power consumption specs for the 2500+ would be 53.7W (watts) typical and 68.3W max at the stock voltage of 1.65V. The 3200+ is 60.4W typical and 76.8W max, also at 1.65V. (For reference the max power consumption for a 3.2 GHz Prescott P4 is 103W, the 3.6 GHz part is over 110W!)

The 2800+ part runs at 2.083 GHz on a 166 MHz DDR (333 MHz effective) FSB. That means it uses a 12.5 multiplier.
-
u are so smart. i was thinking what about a 3000+
-
There are two different versions of 3000+. The original version is a 166 MHz bus 2167 MHz part. That would mean it's using a 13X multiplier. The newer version is a 2100 MHz 200 MHz bus part. That equals a 10.5X multiplier.
-
Is the fist one faster or the one with the 400mhz fsb faster? Where did u get all this information from??? THanks alot .
-
It would depend on the application, but overall the 2100 MHz version with 200 MHz bus would probably be a little bit faster.
Honestly, since you have the DDR400 memory already, I'd just try setting the FSB frequency to 200 MHz (up from 166 MHz) and try it. You can reset the CMOS if your system fails to boot. Also, many newer Athlon XP chips are multiplier locked. This means you may not be able to change the multiplier, only the FSB frequency.
Where did I get the information from? It's what I do for a living... ;)

I did this and it now says my computer is a 3200. how come it does not say 3000???
-
Sounds like you have the multiplier set at 11 and FSB at 200 which is the stock setting for the 3200+.
-
Well i have just decided to overclock it to a 3200+. Now that I have done this do i need to do any thing else??
I have it set as 200fsb and 11.0x multiplyer

its fine now. i had it at 10.5x and it still showed up as 3200 so i just have decided to go with 11.0x
-
Jay, the bios identifies the processor model rating by a table. You will often see Athlon XP motherboards without the very newest bios revision identify any Athlon XP running at a 200 MHz FSB frequency as a 3200+, as up until recently it was the only Athlon XP that used a 200 MHz bus.
-
THanks for all the help bloom. im playing america army now to see how hot my processor gets. It was at 44c at 10.5x now its at 42c at 11.0x.

I just fliped one of my fans and my temp went down to 30c with my computer overclocked to 3200:)
