Quality of mining cards

Computersloeber · Aug 23, 2014

Hey,

I recently bought a stock sapphire R9 290X for €200 which was used a couply of months in a mining rig. Now I don't know how bad this is for a graphics card. I know the temparature changes are bad, but how bad exactly?
Can someone enlighten this for me?

Hardware is rated for the amount of hours of normal use. Imagine mining being a street fight. The card is Napoleon Dynamite and the mining program is Arnold Schwarzenegger. It beats them up. It doesnt take long but it might do fine. I personally would never buy a 290x (probably the hottest running card on the market) because they burn up from improper cooling. In terms of bad, replace Napoleon with you in the fight.

But if the card runs at a safe temp then I assume there would be little to no problems? How long do you think cards would last in a mining rig?

You could definitely have problems. If they were ran to hot for to long then the caps and vrms could be shot to hell. Chances are that they arent as long as the seller is a reputable seller. Cards would last a long time if they were kept at a low temperature away from there max. Most arent though as you have 4-6 cards running at full speed next to each other for days on end. I'd say they would last 6 months if kept at a fairly warm temp in a rig. As a gaming card probably a year of intense gaming daily.
