How Hot Is Hot ???

[UnseenMenace]

After a little pushing I obtained an official remark from AMD referring to CPU temperatures.
AMD seem to consider that anything up to 90 c is acceptable when running a CPU rated up to 1000 mhz and that anything up to 95 c is acceptable when running a CPU rated higher than 1000 mhz.
They also stated that if you can boot into the OS and the mouse pointer does not stick or judder then any heat related problems are not related to the CPU.

I personally consider this information to be 'suspect' to say the least as from my experience I find that my AMD becomes unstable around 60 c and displays this by random GPF's in Windows. I also believe that the heat pushed out by some processors can effect surrounding cards however would you view personally this as a CPU heat problem or a problem with the respective card if it suffers from this heat.

What do you make of this these claims by AMD ?
Please provide as much information as you can as I now have a contact on this situation and would like to make AMD aware of our opinions.

I think they are hog wash. I am sure they can take the high temps for a few brief seconds and so forth and come out unscathed *if* you are lucky. 60c is the extreme top end in my book for any AMD CPU. Others will prob contradict me. Just sharing my thoughts and opinions :)

My CPU gets shaky around 55 C (read: 65 C with asus probe). If I try to do any heavy duty work or games it either locks up or becomes unstable to the point of a BSOD.

Do some more probing and see why it is that certain CPUs (mine is AYHJA K) only go to <60 C before they cause problems.

My AJFA gets unstable at 53'C while at 1200. I think AMD is doing some wishful thinkin on this one.

Hogwash is right. My duron becomes unstable at 60c no mater what speed its running. AMD is probably just trying to pass the blame to someone else like motherboard and card manufacturers. I don't even think many heatsinks rated up to 1.5 ghz should be approved by AMD.

Common guys and girls let me have more of your views I would like to get back to AMD with more opinions than four !!!

BUMP

Well there has been much talk about CPU's running in the mid-50's and that is acceptable. I do not share this view. ANYTHING over 53c, you are risking your stability and/or your presious CPU. I have spent great a deal of time and money to NEVER let my chip see 50c+. These guys with their coolmaster (stock) heatsink and fan running at 50c to start and then wanna O/C. That is just asking the overclocking gods to crap on you!! I think I may be following in Hoot's footsteps in being almost religous about my temps. If I reach 40c (idle) on the hottest day I am not happy. I truley think temps have a great deal to do with some people not O/Cin' well. Especialy those 1.4's.
I will get down off my soapbox now.

My 1GHz TBird run rock stable at 57c idle and 58-59c under load. And when I say rock stable i mean it...seti, IRC, ftp server, and UTournament, i have left it on for days before without a single crash, hasnt crashed since i got it, and when i installed a new screensaver? I run win98SE

[TranceBear]

Very nice Cronos. That was just my views. I have seen these chips run good at high temps, but with all that is out there to keep the temps down, I wonder why run so high?

[diehrd]

Funny but on my AXIA at 53c she gets unstable.

I had the alpha pla 6035 switched to the SK6 and run stable at 9x150 at a max of 45c.

Now for the amd specs,I think these boards we use are way off in actual temp readings and the higher it reads I think the bigger the margin of error.

At 53c on my ABIT KT7a I would bet actual PROCESSOR core temp is in the hi sixties,And if this is even close to true than AMD is full of crap tha 90c is max operating temp.

[lemmingboy]

I agree completely about getting over 55C or so causes instability, but maybe this isn't because the processor is to hot maybe its other components. The CPU at these temps is dumping tons of heat into the case, maybe the chipset is crapping out from second hand smoke.

Just an Idea!

[quegyboe]

Well for me, anything above about 60C on my Duron is too hot. Not that I know that well, because my chip never passes 45C with the Volcano 2 I use.

[JuDgE_DrEaD]

Money is the limiting factor, the almighty dollar, im out of work right now so nothing better than my Coolermaster :(...for now

[Cowtown]

I am not sure what you guys are doing, but any of the AMD processors I have seen clear 60^'s have worked fine. In fact, my system which typically sits around 48 with my FOP32 can hit mid to high 50's, and even 60-62 on occasion when playing games on a very hot day with complete stability. Perhaps it's something else in your system? No...

Do you really think that is air you are breathing?

i get various anomolies and lockups over 55 or so, since i put the watercooler on its nowhere near there now, 90c is rediculous, and it concerns me that amd states they would run ok there, even in their technical docs it say that 90-95c is the max rating meaning failure and damage above and beyound, we can all attest to that fact

[Paiynn]

I dont think it is the temps that are making your machines unstable, I think it is the MHZ at which you are pushing them to. And people are just assuming it is the temperature. Maybe as a test try something like this: Run your machine at its rated MHZ and intentionally get the temperatures in that 60c range either by removing your HSF, or taking off the fan. Might be risky to do it without getting REALLY high temps but I believe you arent going to have problems at those temps if its at its rated MHZ.

Dats what I think!

[PDL]

This new 1 gig AVIA runs at 49c/1.7 Vcore @1.31GHz...but I think that is too hot.
Not because anyone has told me it is too hot, or that I have a manual that says so, it is because that is what I think.
There is so much info out there and so much good and maybe not so good advise that it is not difficut to come up with a range of temps that you feel your system is best at. It is different for each system and each OCer.
AMD on the other hand is not interested in overclocking from a business standpoint. Consider their information based on STOCK everything and it makes a little more sense, but I too think they are 'reaching' with those temps.

[Wega!]

My Duron has never been above 57C, Í always get an error when I hit 55C. That's when I run @978MHz When I'm @1007MHz I get error's at 53C.
But when is it a processor error and when is it an OS error?
