How hot can my AMD Barton 2500+ get (safely) when oc'd to 3200+?


What is the safe limit? right now it is about 41 degrees c constant. This is a retail cpu and thus I am using the retail fan. How good are those fans? Also is there any free software I can use to do a full test on it?

Not sure, 50 degress C is my absolute "chip limit" - but I watercool, so heat isn't really a problem (average of 20 C under load ;P ).

These guys probably know, search the forums or read a guide or two: www.hardocp.com

you definitely can do better than the retail cooler and fan. look into thermalright heatsinks, they are a great value. SLK-800 and 900 are excellent, and there are just too many good fans to list. thermaltake smartfan II is often recommended with those HS.

i have an older thermalright AX-7 with a ys-tech ~40-45cfm fan, and my temperatures at 3200 speeds average in the mid 30s. an 800 or 900 w/smartfan II would probably kick that down another 3-5C, at least. make sure you're using some good thermal compound, too -- i.e., the latest arctic silver, or i hear their new ceramique is awesome.

I got 49 degrees on a regular basis w/o overclocking.
According to the AMD data sheet for 333 Mhz front side bus XP's the maximum die temperature is 85 degrees.I wouldn't try to do that for long though.

Retail is only good for one thing. Warranty. You get a three year warranty with a retail processor compared to one year for an OEM processor. The retail HSF is the very least that AMD will allow, and still hold true to the warranty. However they don't honor a warranty if you don't use the recommended HSF. This is so that they know you have an adequate fan for your processor.
According to AMD you are good, as far as temps go, up to 85c.

Yes. I forgot to mention that, crashmeister. I figured he was well below that anyways.

part of the chip code on the sticker will reveal the maxium temp for
that chip, but you'll have to look it up on some site that "decodes" that
info for you.

Mine runs 36C at idle with a 78F room temp. It will run up to 42 to 45C when running at 100% or so. I have a Thermaltake Volcano 11 with the auto temp control thingy attached to the CPU. The hotter the CPU gets the faster the fan goes.

Better keep that thing . Don't forget about the other stuff. Video card and memory etc. Might cook one of those. They do make coolers for those you know?

Later. No smoking please or you will

Well it was fine at 41-42 until windows update finished and I started to install. Then when the processor was at about 40%, it shot up to 50 degrees in a minute and a half. So that's not good. I put it back to my auto (11 i guess)*166 (2500+, for the 3200+ 1*2000) and booted up redhat 9. I had taken the leave to boot it up as a 3200+ and time it then too. I got exactly the same time (81 sec). So does overclocking really help? The usual voltage is about 1.65 v and I had to put it to 1.775 for stability in windows, so that could make a difference. The fact that i had to do that shows that it seemed to have been overclocked, but now i don't know. Should I go ahead and but a better fan (have about 30 bucks) or forget it cause it didn't seem to do anything for me?

Another thing: does overclocking really speed up your cpu? How can it be told to "go faster"? So why doesn't AMD just oc their Barton 2500+s and put in a better fan?

I understand how TO overclock but I don't understand WHY it works. anyone know the core changes made to the cpu that make it operate differently? Just interested.

Thanks for all the help.

Well if it were possible to overclock the old 8088 to say 1GHz that old DOS would be smoking. Overclocking does speed up the system but at the price of the life of the CPU and stability sometimes.

Imagine this. You go to a auction and the guy talks slow like we normally do. We may understand him better but he won't sell as much stuff. Takes to long. So he talk faster, much faster, so that he can move the stuff through faster and sell more. Make sense?

If you are going to overclock, get a bigger cooler or go to water cooling. It may save you $100.00 on that CPU, at least once anyway.

I have been running a process at 100% since last post and my CPU is at 39.1C and the room temp is 28C. Pretty good I think. Case temp is 31C.

Later

Booting up as in loading kde or gnome with all the fixin's depends a lot on the disk and less on the CPU.If you want to check for any speed gains try to compile something or encode a movie and see if that goes any faster.

I don't really know a whole lot about what exactly OC does, but I do know to some extent. My Q is if ur CPU is running @ ok temps overclocked like around 50 C, can ur CPU still get damaged somehow? Some guy @ CompUSA said it could, but I really didn't get the impression he knew what he was talking about. Could someone tell me exactly how bad OC is for my CPU?

I have never overclocked one before so this is what I have read and such.

As long as you keep those temps down you are most likely OK. You can however have a hotspot inside the CPU and cause a failure. If you really want to overclock then you need a really good heatsink or watercooling.

I don't really think overclocking helps that much anymore. The bottleneck are elsewhere if you have a 2200 or higher, give or take, CPU. The IDE is one limit but there are many more. Even the space shuttle can only go so fast. Mine spends most of it's time waiting on the hard drive.

Get a really good hard drive that is fast and a good mobo that supports it. That will help more than anything. Get fast memory and help even more.

There is a lot of things that will speed up your system, but you only need one bottleneck to slow it all down. A fast CPU is just one of them.

My two cents worth.

Later.

In short - the hotter a CPU gets the shorter livespan you can expect.It probably wont make much difference if it isn't under constant heavy load although getting it to 3200 is unrealistic.Have alook here http://www.hothardware.com/hh_files/CCAM/amd_axp_2600(2).shtml
