Topic: Will minning bitcoins kill your card? - page 3. (Read 11903 times)
got the cheapest 5770 i could find and it's been plugging away 24/7 since june- got a 5870 too but it's only active 50% of the time since I need it's RAAHW POWAH for producing stuff.... no problems at all for either of them at all.
technically you should breakeven before killing your card, but at today's difficulty/price ratio I'm not so sure anymore 
I almost killed a 9600GT, my first mining card. After a couple days of running it will start to artifact on its own not even mining, just showing a Windows desktop.
My 5830's have slowly lost overclocking abilities. I used to be able to push over 1,000MHz, now I can barely hit 980MHz. For a couple of weeks I was running super high voltage on them also. 24/7 mining + heat (especially if you crank voltage) will definitely kill a card. The big boys that have large farms are no strangers to flat out smoking cards and having to replace them left and right.

Clearly, yes, chances of killing a card will go up considerably if you stress them 24/7, particularly if you overclock them and dont provide ample cooling.
Its simple really, running a card causes electromigration. Think of it as erosion inside the chip. Electromigration is worsened by:
heat and voltage (and very much so!).
Its like running your car flat out. Its designed to run flat out, and it shouldnt break just because you do it, but chances of it breaking down do go up considerably if you do it 24/7. But its still only a chance. Was it saab that ran their cars for 200.000 Km flatout on a circuit some years ago as a publicity stunt? Dont remember.
Anyway, for some more anecdotal evidence, mining with old 8800GT, 2x5850 and a 4770. One of the 5850s died after a month.

Yes (some faster than others, some not at all). I run distributed computing (Boinc) projects before mining so have stressed cards longer than just June. My graveyard covers quite a few. Not running o/clock, and most are mem down clocked.
HD2600 - it was a cute card
HD4850 - several
HD4890 - nice card, ran hot
gt8800 - still going, but suspect
gt9800 - simple fail - not even artifacts
gtx280 - major artifacts on load, will not compute
HD5850 - tried the "oven bake" fix on this as a test, but used the fan in another card.
HD5850 - meh
HD5970 - XFX black edition, very nice paper weight
HD5970 - screens of death (blue, grey, green, black - I think the gtx280 was the only one with a pink/red screen of death)

I lost one after a power outage outisde of that no troubles
had a fan get noisy on an asus direct cu 6870 (1000/300) I bought in june 2011 running the fan at 85-90 % (this before using cgminer with its auto clocking and auto fan features) . oiled it and its fine now but Im not impressed. couldnt return it as I had already replaced the TIM with AC MX-2
been doing folding for years on various overclocked but well cooled cards. never killed a card but Ive killed some fans over the years. keep em under 75% if ya can.

I have had several cards i used to run alot which died or has been failing somehow
The issue is did overclock damage it or the constant stress from running almost 24/7
The problem is actually you never can say if they would have died with or without the constant stress
Overclock code N = non, L = Low ( 5 to 45 Mhz), M = (45 - 100 Mhz) and H= High (higher then 100 Mhz or more)
Nvidia 6800 GT, N, usage: Physx and gaming about 12 hours a day the hottest card i ever owned ( 123 C)
Nvidia 8800 GTX, L, usage : distributed computing 24/7, suddenly burned down
Nvidia 9600 GT, L, usage : physx + Distributed computing, from scratch gave artifacts slowly died
Nvidia 280 GTX, N, usage :physx _distributed computing, burned down
Nvidia 440 GT, L, bitcoin, died yesterday 4 months old
Ati 4830, H, usage: distributed computing, slowly ran every month lower clocks till sudden dead.
Ati 4890, N , usage : distributed computing, i think the enormous heat damaged it ( 112 C) still worked but xfx replaced
Another thing some cards at start i had made huge overclocks but in time i constant had to lower the overclocks since they give artifacts or crash at the previous settings
I had 4 x 4850 which ran at very high overclocks but slowly began to decay in speed at the end they hardly went above stock speeds.
I somehow find the ati cards however giving me much more stable cards if you keep them stock speeds.
Only one ati died out of 27, compared to nvidia 5 out of 8

I am curious if anyone has had a card from around june or before that have been minning non stop that have caused problems? I am specifically looking to see if anyone who games and mines bitcoins and if they have had artifiacting or more crashing or if the card died.
Well I have had one die off out of 16 and a second that at the moment is displaying signs of going tits up as well so take that data point as you will started this mining thing in May.
How OC'd are you with them, and are they adequately cooled?
