My video card idle temperature varies. For example; few days ago it was 49, now 54. Its 22c right now in the room.
my cpu idle varies alot too because the room is non heatable, so in winter time its mad cold and cpu idles at 10c :) right now idles at 30c.
I have antec 900 case and 120 tuniq tower, and video card stock cooler. Case and cpu coolers set to max, video card to 85%.
It really depends on conditions around and inside your machine.]]> http://www.dslreports.com/forum/remark,20569437 Sat, 31 May 2008 15:16:09 EDT Re: [OC] EVGA 640-P2-N821-AR GeForce 8800GTS 640MB 320-bit GDDR http://www.dslreports.com/forum/remark,20547125 Keizer :

Man, you need better cooling. I have never seen 71C ever, even when over clocking, and running modern games on my 8800 GTS.
I'm using the stock cooling solution provided by EVGA on the card. Even at stock speeds, this card idled in the high 60's. I'm sure if this was excessively high, EVGA would have done a better job on the design. The card has been running fine for over a year. No problems. For me... If it ain't broke don't fix it. :)
I'm assuming that I have extremely good case cooling then. I have a huge Lian Li server case with really good case fans.

I still can't believe the other posters card only goes up 1C during game play. ]]> http://www.dslreports.com/forum/remark,20547125 Tue, 27 May 2008 16:49:23 EDT Re: [OC] EVGA 640-P2-N821-AR GeForce 8800GTS 640MB 320-bit GDDR http://www.dslreports.com/forum/remark,20545860 jsimmons :

Mine idles at 48C, and goes up to about 62C during COD 4, and BF 2142. Temps reported from Everest, and Riva tuner.

Are you saying your card only goes up 1C during game play?
Yes. And that's using Everest to monitor the temps.

While we tend to panic when system CPUs hit 60C, the video CPUs are very happy at 80C+. My 8800 GTS idles at 71C. Peaks between 85 and 90C during ATItool.

When atiTool starts causing crashes, you've pushed the CPU or memory well beyond its limits and have to back off.

Generally speaking, these cards do not have a huge amount of headroom as EVGA has already boosted the speeds above the Nvidia spec. I had to drop mine a little below the level ATItool found as the max since I'd see sporadic problems that didn't show up in ATItool.

Thanks a lot for the posts.

edit: atittool even at default settings keeps lagging badlly if 3dview is open.
When i tried to find out max core temp, at 669 mhz core speed i got blue screen and pc restarted. I dont get it why my screen keeps freezin even on default settings in atitools when 3dview is open?

edit2: i am running at 645/1493/910 and fan set to 85, and i used evga tool. I see no artifacts and games doesn't crash. Still wondering what is safe temperature for video card?

to me its working fine, but i am going to stop here because i dont know much about overheating in video cards.

EDIT: Allrite, i read the article, its very handy. It explains a lot. It seems while for processor oc is better to do it thru bios, in overclocking of video card is different-- much more secure and easier way is... software overclock. I'll go with riva. Thanks for the link.

Question is, in the article there was no mention of safe temperature range, or temperature monitoring. Can anyone tell me about it?

Everything else seems pretty clear... small raises of mhz and then checking if it works stable. When you reach the crash or artifacts, go lil bit back and you all set. Am i right? :)

thanks

edit2: is it ok if i would be runnin 3dmark06 to check for artifacts instead of a game everytime i raise frequencies?]]> http://www.dslreports.com/forum/remark,20515976 Wed, 21 May 2008 05:36:20 EDT Re: [OC] EVGA 640-P2-N821-AR GeForce 8800GTS 640MB 320-bit GDDR http://www.dslreports.com/forum/remark,20515949 eX_NihiLo : TomsHardware did a recent intro. »www.tomshardware.com/reviews/ove···916.html Read it and ask any followup questions.]]> http://www.dslreports.com/forum/remark,20515949 Wed, 21 May 2008 05:11:13 EDT [OC] EVGA 640-P2-N821-AR GeForce 8800GTS 640MB 320-bit GDDR http://www.dslreports.com/forum/remark,20515923 ZaRRaZa : Hello, previously i have had experiences with overclocking proc and rams, but i never did oc of video card.
how is it done? can video card be oc'ed thru bios? i heard something about riva tuner program. Which way is safer/better/more stable?
i built this system in july 07, and always had in mind to overclock it. I did some basic oc, but now i want to push my machine to the limit and get the best of it. So i am looking for advise, wise thoughts and important info such as, how should i monitor video card's temperature, what is considered hot, and in what range temperature should be and things of that nature.

Thanks in advance
