Safe temperature range for Athlon Barton 2500?

[Rand3000]

I've got an Athlon XP Barton 2500+. I overclocked the FSB to 200 so I'm getting Athlon XP 3200 speed now. What I'm wondering about is what is the safe range for the CPU and Case temperatures. I ran Prime95 overnight and the temperature in the morning was 33 C on the system and 42 C on the CPU.

those are perfect temps. go have a beer.

Temps are fine. And you got a 2500+ that did 3200+ and passed Prime?

Good work

It was pretty cool that it overclocked to 3200. All I had to do was change the FSB in the BIOS to 200. One question I have is I think my Barton is locked (it's a week 44 barton), but I was still able to overclock the FSB. What do the unlocked Bartons allow you to do different?

For Bartons like mine which can't hit that 2.2GHz speed.

I run at 200MHz x 10.5 to get 2100MHz (3000+).

It gives you a little more flexibility.

It also allows you to go 200MHz x 12 to get 2400 MHz if you have a real good chip but sucky RAM or something like that.

basically, locked means that you can't change the chip multiplier. whether or not the chip is locked, you can change the fsb (which is what you have already done). having an unlocked chip gives you greater flexibility in your OCing.. so say your memory couldn't run at 200MHz fsb but you want to reach 2.2Ghz... you could keep the fsb at 166MHz and raise the multiplier to 13.5x to get a clock of 2.241GHz, or basically any combination inbetween.

Thanks for the info. So it sounds like having an unlocked chip wouldn't change my OC performance since my RAM is PC3200 so I can keep it's speed the same as the FSB, is that right?

right

but... If you could change the multiplier you might be able to run @ say 220 x 10 instead of 200x11. Assuming of course your system can handle that, which it should. That way your memory and everything is running a bit faster, and the CPU is still stable.
