"soft o'clocking" (temperature guidlines)

Would need some temperature guidelines for my 8600m GT. runs around 52C standard. up to what temp. can i safely tune the card up? where does it become critical?
Cheers

this doesn't do much good for your specific model, but I had my 6800go overclocked, and it ran at about 55C, i think anywhere around 60c is tolerable, but above 65 you should be worrying.

If I'm wrong, please correct me.

 

I was told that you should start to worry if it goes above 80c. mine is OC'ed to 580/445 and reaches 72c max.

 

wow, that's pretty high temps. mine is O/C to 610/500 and i get max temps up to around 58-59 degrees, playing COD4 at 1650x1050 maxed out.

 

What are you reading the temperature with? I was told that you are suppose to add 13 degrees to the readings, with I8kfan, otherwise, I would of have 58-59 temperature readings as well if I used rivatuner. On the other hand, it is better to be safe than sorry, so I used the higher temperature as my guide line. =P

 

yeah thats pretty low. I have downloaded rivatuner, ATItool, and Ntune to see if there was any difference in temp. the Ntune monitor reported temps that here almost 10c lower than atitool and rivatuner.

 

Most of the graphics cards these days are safe into the 80+ range. I beleive most nvidia's will start throttling at about 90c.

 

it was risky but i guess the max core to clock it up to is 640,
above that will result in the computer crash and requires reboot
but just to be safe, 600 is big enough...
i don;t know the max mem speed Yet...

 

Stock 8600m GT GDDR3 - idles at 70, up to 90's while gaming. And that's not just mine.

 

Throttle is actually 130C I believe. Anything over 90C, however is start for cause for concern, but really anything over 100C is where you should start thinking about downclocking or added cooling or undervolting your CPU or something.

 

im easily gonna second lithus's post....55c...i envy you...in fact....60c i envy you...

im pretty sure my gpu goes well above 90c during gaming...
my cpu along goes to 65c+

both cpu and gpu can handle temps pretty well...OC'ing your gpu will knock some life out of it..but as long as you dont go too mad, it should be fine.

and yes. temp programs tend to be less accurate at judging temps mainly because of temps emitted by cpu and other components...so alwasy add a few degrees to initial temperature output. but i wouldn't worry too much unless you hear your fan nearly flying out or glitches while gaming.

 

Mine idle at mid 60'sC, and when pushed will run into the low 80's, and with an overclock they'll pass 90C. This is an SLI 8600mGT with 2 gpu's.

 

do you think that it is just a GDDR3 card that has high temps like that? I've noticed that most GDDR2 cards are claimed to have a mid 50s to mid 70s range. thats also what mine has. BTW, after switching from 169.04 I now get artifacting in ATItools where I didn't used to get any.

 

yeah, i think it might be GDDR 3 cards...

anyway...youre OC'n right? ATItools did that to me too.....try powerstrip or atiTRAYtools.

at the moment...powerstrip is my fave. TOO many options to even look at.

 

No, it's not that GDDR3 cards are hotter, it's that the cooling in the G1s sucks ass. The GDDR3 cards are cooler than their DDR2 counterparts, at least when idling.

 

really? i cant really say much since mine runs kinda hot. my cooling is noisy but effective (one giant fan)...but the gpu i got (x1900) emits ALOT of heat...but ever since i got it a cooler, during gaming my cpu reaches 62c MAX.

whats the cooling in the G1 like?

 

hmm, now im wondering how much i can push this 8600gt ddr2...

its stock clock is 475 for core, and 400 memory. for some reason or another, the gpu driver crashes when i take the memory above 570, but ive got my core clocked at 600 w/no problem.

I usually see ~78 degrees when gaming at stock clocks, and around 81-82 when oc'd

 

570 is extremely high for DDR2 memory. It's crashing simply because the memory is not stable at those speeds. I'd downclock it to 550 or 545 and push the core up as high as you can.

 

I keep hearing that OC'ing the GPU will knock life off of it... How serious is this? And it is only when it's overheating? Or will OC'ing in general wear the part down substantially faster? Obviously, common sense dictates that the faster you push a hardware, the faster it'll wear down. I just want to know how substantial the difference is.

I don't really care if the difference was something like:
Stock clock: Lasts 10 years.
OC: Lasts 9 years.

But if it's actually substantial (like Stock lasting 5 years and OC lasting only 3 years), then I might think about not overclocking my GPU until absolutely necessary (this laptop better carry me through 4 years of university! Obviously not gaming wise, but I'm hoping I'd be able to use it to take notes and whatnot when it's on its last legs).

Right now, my clock (DDR2) is at 550/525. I didn't dare push the core up any higher since the temp is already hitting 66C while playing GeOW (this is reported using SpeedFan. nTune reports 7C lower temp...).

 

OC'ing will bring out any manufacturing defects in the card quicker. This may or may not matter, depending on well your card was made. It's really luck of the draw.

 

Ah, thanks.

Seeing as I'm not much of a gambling man, I think I'll stay on the safe side of things .

 

However, the flip side to that is that in my (pretty extensive) experience, as long as the OC doesn't significantly affect your temperatures, your laptop's life-length won't be affected noticeably.

 

Ah, that's also good to know.

 

I overclocked my 8600 GT DDR 2 to 633/520 and running 3d mark 2k6 the temperature of the GPU never got above 59C. I am using Everest to monitor the temperature, how accurate is that? I don't want to fry it by thinking the temperature is lower than it actually is.

 

good. I won't be worried anyway because I'm going to replace it with a better card in the future if I ever can.

 

My max. temperature i get when i OC my 8600M GT GDDR3 in my Asus G1S is like 95°C (MAX !!)
My OC clocks are 600/720 (But yesterday i turned it down to 575/720 )
At stock clocks i get like 87 °C i think (475/700)

 

It's not so much overclocking as it is the heat. That's really the killer. As long as it is witihin spec it should last the "normal" lifespan. Of course something running 10c hotter than a similar GPU will shorten it's lifespan considering everything else is equal.

I'm not sure what the "normal" temps are but I'm sure anything below 80C is more than safe, probably below 90C. Considering gaming will probably only be a fraction of the time time (at least less than 50%, probably much less I am assuming), the rest of the time it is running much cooler, so it shouldn't be an issue.

With your example: Stock clocked 10 years, O/C 9 years is probably about it. Maybe 10% less lifespan at worse case scenario.

 

Some of these temps seem INSANE to me. I have an 8600m GT ddr 2

I idle at 40-45C and the highest I've ever hit I think was 66 C after like 4 hours of CoD 4 at high/max settings. I have mine OCed at 625/525. It does me well .

 

I idle close to 45-50C depending on how long it's been on and what I just got done playing. I've hit 55C playing BF2 maxed out.

Just started trying to OC(630/550), and my 3dmark06 score shot up 1000 points. Still only hit 55C. Could be due in part to my cold climate (Toronto, Canada).

 

I overclocked my QuadroFX 570M from 475/350 to 650/500. Temp went from 84 to 91°C under heavy load (tested with crysis and UT3). It's DDR2.

 

wow, thats a good temp. i see youre notebook is going to last you a while.

i think alot of it depends on the type of cooling you have too...and how well designed a notebooks cooling system is. i guess you can OC more if its well made.

hmm. then again...BF2 doesn't stress my notebook that much. play the CRYSIS demo then see how well youre notebook keeps cool.

 

Much appreciations. I was wondering why it would do that.

SO... is the gpu temp is more dependent on the core clock? ive been up to 630 before and got up to 85c

 

It depends on how exactly your laptop's cooling system is set up, and where the measurement is being taken.

 

My Gateway T-1616 runs at about 70 C just surfing net and watching some online videos.

 

my card ideals around 55-60 and in gaming goes from 60-73 max (that's with 13 degrees added to the original temperature reading I'm getting).

520/475/1040

with 169.01 drivers, I think I need to update but don't know what ones..bleh..to many mixed results to decide.
