I'm using Asus R9270X-DC2T-2GD5 for mining and the temps remain stable at 68C or below even with 99% GPU load for hours.

Stock cooling with my Cooler Master CM 690 II case with positive air flow. I can move the case to a more ventilated area or just take of the side panel for greater airflow.

  • What are the ideal config params for this specific card?
  • Do the temperature readings look Ok?
  • Do I need to do anything more in terms of cooling or tuning the card (its already factory overclocked)?
  • Is mining going to make the card fail early? If so, any idea how early? I'm OK if this cards lasts 2-3 years as opposed to 4-5 years.
  • Are you mining Bitcoins? If so, I'm afraid you are out of luck. That GPU Mining train passed a long time ago. Try Litecoin. – T9b Dec 18 '14 at 12:33
  • Yeah, was afraid so. Thanks for the alternative! But what about rest of the questions? – Mrchief Dec 18 '14 at 15:53

    I can't answer those unfortunately. That's why I posted a comment and not an answer. – T9b Dec 19 '14 at 12:04

I can answer some of your questions, I agree with @T9b you are out of luck with BTC and should try some Alt Coins that you can mine with a number of different Algorithms: Litecoin and Dogecoin (Scrypt), or Darkcoin (X11).

For optimal parameters to mine a Scrypt coin I suggest you try this comparison which is pretty detailed and has most of the GPUs out there:

Temperatures looks more than fine at 68C, I had a few R9 280 and was struggling to keep them below 80C.

If factory overclocked there is not much else you need to do. I suggest you run the Asus Utilities that came with your card to monitor temps, fan speed, etc. Make sure there is enough air circulating within your PC case.

If you mine with your card 24/7 it will fail rest assured, predicting when it's a bit more difficult as it depends on the card components and build quality. Your card is factory overclocked so it will be even more prone to failure if constantly run for mining purposes. I would say a year max, but then some cards fail after 2 weeks or 3 months, etc...

Test it out and make your own judgement, I personally don't think your card will earn you much with mining. That doesn't mean you can't try it out and have some fun with it, you may learn a few things while doing that. ;)

  • Very informative! Grim deadlines but yeah, all in the name of learning! :) – Mrchief Dec 23 '14 at 4:32
