Bah :( Not a happy bunny.

Just got into this mining thing less than a month ago, with a miserable nVidia GTX570. My 250KHash were doing admirably up until now, but I should have known that 89 degrees C for 15 days straight would bugger something up.

Oh well. Roll on the end of the month til paycheck and 2 shiny new R9-280Xs :)

Just a general grumble!

I have a temp cut-off at 80C just to be safe.

Sad to hear that.

Just as sakkosekk mentioned, you should set up a cutoff temp, and it is easy to do with CGminer or BFGMiner.

Yup. Lesson learned.

Ah well, it was always only going to be a learning card til the real hashes arrive :)

Rit.

So how hot are you planning to run these new cards?   ;)

I hope you bought a AMD / ATI GPU now ;).

I've got my temp. cut off at 82 degrees (and I'm using a HD7950).

Try forging NXT. No GPUs required.

You're not the only one.

So Nvidia cards are less resilient than AMD cards, mine is an amd and going strong for almost  2 years.

NXT is a good option

I had it in a case also, could probably have had better ventilation. Truth is that I was being a bit blaze about it because I know I have a couple of decent cards coming this month. When I add those they'll be on risers and they'll be uncased. Also I'll be making sure they have a temp cutoff this time!

Rit.

Is there any tutorial on how to cutoff the mining once the temprature reach 80c?

Seems the case - else OP is very unlucky. I've had six 270s running at 87-95*C for months without issue. Five more run at 86-92*C.  Other eight chill out at 78*C or less because they're outside. (inside ones provide free house heat). A separate 5850 I saved from Bitcoin GPU days for general computing purposes has been heavily used and now hashes Scrypt like a champ. Once Summer rolls around, they'll all be hashing at around 95*C and enjoying that lovely outdoor humidity. I've never had a single GPU fail, including over a year of 16 5850s hashing SHA256 at fairly high temps. Seems about as common for a GPU to fail as a CPU anymore, which is to say it's extremely unusual (except for laptops, which generally have the cooling capacity of a PC put in a giant hole and covered with dense clay).

Associated honesty: though I'll always recommend top-shelf PSUs to others because I'd feel bad if their families had their faces burned off, I run the shittiest shit able to be shit out the shit-maker. You know - the not-even-gold-certified OEM garbage which hums so loud you can't even hear people in the same room, which is on 70% clearance sale direct from the manufacturer's warehouse of misery and regrets, where they ship it out with the metal enclosure mangled and barely hanging onto the actual PSU, where you have to bang it back together with your fists before jamming it into the cheapest case you could find so it can run on the $30 motherboard utilizing the latest 1-star 2005 refurb HDD (complete with an IDE connector) semi-attached to the case by only one screw. ;D

Another fun fact proving why I deserve this forum handle: I didn't like the results given by home routers I had laying around, so I have my general PC (which is a bunch of components on a modular plastic shelving unit -- no case for three years, eaten and drunk over) taking a wireless signal from phone by using a dongle, internally bridging the connection to a LAN port which runs to a large Ubiquiti router. The general PC won't accept an Internet connection through the bridged connection, so a second dongle pokes out the general PC's motherboard. The Internet setup is made more complex by an outdoor and indoor antenna boosting 3G and 4G signals. Naturally, these aren't hard-wired, but instead run loose along the floor. Still, this is far superior to my previous solution of making my own phone antennas out of copper wire and gorilla tape (this eventually ruined the phone's 3G radio).

This made me seriously LOL ;D. I've run a few machines like this myself and they're surprisingly resilient!

Update on the graphics card:

I removed the casing, the fan and all the foam, gave it 10 minutes in the oven at 180, left it half an hour to cool, reassembled and....

...good as new, and hashing at 10KHash faster than before ;)

Rit.

You can use commands for CGminer for that. Add for example --temp-target 76 --gpu-fan 25-80,65 --auto-fan --temp-overheat 82 to your file. This means that the fans start working harder as soon as the temperature hits the 76 degrees, that the max % of fan speed is 80% and that the fan speed will increase to 100% as soon as it hits 82 degrees.   There's no need for a temp cutoff command then anymore, but you could add it if you like.

For less heat, do undervolting
But this is risky void the warranty!

I feel sorry for your GPU card. Next time try add other external cooling option like extra fan , ac.

Very nice. I know doing this works sometimes (sometimes points disconnect due to continuously "high" heat). It is quite interesting that it is running 10Kh/s faster. Anything you did in particular when reassembling it?

I wonder where are the times when people actually used good graphics cards mainly for gaming purposes ;-)

Nothing special when reassembling it, and the hashes have now settled back down to where they were before it fried. So it was just a short lived boost, unfortunately.

Only thing is, I have done this with graphics cards before and they rarely have much of a life left in them after the oven treatment. If I get the rest of the month out of this, I'll be happy enough.

Rit.

That's soooo old skool.

Yeah, I had a laptop several years ago and when the video card died, I tossed it into the oven and it worked for about a month. I actually tried it again when it died a second time and it lasted for almost an additional two weeks. Didn't work the third time though. Ha!

Hope your card lasts you until you get some replacements!

So, did it taste good?

It was nommy. Couldn't figure out why it had stopped hashing, and then it hit me.....the damn vinegar! Silly me ;D

lol, guess your card is happy to hear that, and can now RIP :)
