Hi to all the Pimps and Pimpetts.Im new to overclocking . And dont really want to learn the Hardway. My Question is , does anybody know what temps the Amd xp cpu fries at?>>Mike

You probably won't really ever want to OC near that point ( unless it is a really old CPU).. I think a Pentium4 fries at 75-90C or so.. But an AthlonXP will probably go a bit past the boiling point for a small amount of time ( before complete failure).

AMD rates them for 70c max, in practice, 50c is about it when you start to overclock them.

And I have never seen anyone fry a chip yet that was using common sense

AMD Xp cpus die ponit is 85c. And like Necro said i would not push it past 50C when overclocking

Just for reference it would be DAMN hard to fry a P4 as it will thermal throttle - I read a review where they actually ran one without the heatsink in place and it did NO damage.

Intel - the newb processor

I ran my 2500+ @ 70-75c for a couple of weeks overclocked with stock cooling...didnt blow up.

I think the way it is with the AMD's is 85*C under power and 100*C unpowered.

I had a time when my P4 1.4 hit 102*C because the heatsink wasn't secured correctly, I later found out it wasn't even on the heatspreader, and I just fired it up and it works fine still. That's the only thing I like about the P4.

No but you where probably generating errors all over the place, and that shortens the lifespan alot.

.....can you exsplain a bit how errors shorton the life span of the cpu , i have never heard of this b4?

The errors don't, they're just an effect of the high heat.. What will shorten the life is the heat though.

It's called electromigration..basically, the integrity of the CPU will start to deterorate over time (They do this normally anyway)

Adding heat and/or voltage accelerates this.

look at this explination for the theory behind it.

>> thx for all the great imput .Mike

Keep in mind that the readings you get from the motherboard are usually not totally accurate. With my motherboard it sopposably reads 7-10C higher than what it actually is. I haven't had a chance to test this because I don't have a probe but thats what I have read.

i would say 65 degrees sure the cpu will run at 70 or 75 but heat kills the processor if u run it for longer at 70 the quicker it will die

forget about temps if it is stable your ok..if it gets to hot yo won't be stable

Im not disagreeing with you here but to what degree. For instance instead of lasting 30 years it will only last 15 - I dont think a few degree (10 or so) will significantly impact how long it will last. Does anyone use a 15 year old processor in their main rig today........dont worry about it wearing out.

Agreed. If you up the fsb or voltage don't worry about the damage as long as you are in control of your temps. In theory you double your lifespan by lowering temps by 10◦c , take the average life expectancy of an example amd cpu at stock (remembering how hot they run at stock) then apply whatever non stock cooling it is your using and your more than likely canceling out any negative effects of your overclock providing your stable.

I remember reading some AMD documentation saying "they" can run error free at up to 65◦c , has anyone else heard this?

I have not, but then again I havn't read everything

No, seriously, her is the issue with an AMD cpu.

The cpu generates an amount of heat dependant on what is demanded of it, both your system settings, and the wokload you put it under.

The cpu does not normally live in it's own environment uneffected by outside forces. Instead, it is effected by the heat other components in the case are generating as well as the ambient(room) temperature and other things like the amount of dust that has built up on the HSF slowly degrading it's performance.

So, you can have it set up and clocked well initially and be at a nice safe temp, but given time and changing circumstances it will probably be placed under increasing daily stress. And it will degrade slowly over time also effecting it's ability to function properly, and even it's ability to shed heat.

So shed a tear, a cpu lives a doomed life, but you can have alot of fun with it while it's still kick'n

Cool it well for whatever you intend to do with it. Maintain your equipment, clean it and check it. And if you can afford to play with it, and replace it if it goes boom, then knock yourself out and learn how all this works in the process.

Error free up to 65? My 2400+ run 48-65 all the time for about 10months, never had a crash yet. I have it set to shut off at 70, but its never gotten that high.

BTW, whats your superpi with the 2400MHz Sempron?

EDIT: what time does the thermal throtling kick in on my AMD system? Its a NF7-S, I ser the CPU Warning temp to 65c is that when it starts to happen? Or is they when my pc will start to beep

I'll let you know when I'm home from work. I just state 65 as something I remember reading from AMD, I mean they have to be able to specify some sort of temp don't they, even if user experience is fine.
