How does digging affect your gpu?
« on: December 22, 2013, 06:32:38 PM »
Just wondering how it affects your GPU? Does it destroy it, or is it fine as long as it is cooled?
I am using my gaming PC for digging right now and I'd hate to see my $400 card turn to crap after digging.

How much of an effect will depend on the quality of your particular card, not the brand etc. If you say with normal use for a gamer ~100% load for 4-5 hours per day. With mining you are talking about 100% 24/7. So you would think that you are reducing the cards life by ~80%.
However in reality as long as your Cards components (VRM/capacitors) are running within their specified tolerances the effect should be negligible.

If one of your capacitors however is of a low quality, it will be running outside its tolerances from the day you bought the card, and mining will accelerate its demise. This would have happened anyway, it would just happen faster with constant load.

The best way to ensure maximum lifetime to provide adequate cooling too the card. Hence why alot of people run their cards open air (without a case) to disperse the heat away from the cards faster.
If you only have one card, a decent case with good air flow should be fine. But its a good idea to watch temps, especially the VRM temps as when gaming these never reach the loads they do under mining.
Core temp is far less important to the temperature of the graphics cards components. The cores themselves will shutdown before they get too hot to cause damage. Or you can set cgminer to do it even before the does does. You can find the critical temp for you card via google.

Thank you. After looking on google it seems like the only way to find your vrm temps is with a laser temp gun? I looked on msi afterburner and gpu-z and neither have vrm temps

GPU-Z should show them if they have temp sensors. I guess some cards might not have them. The only card I have checked lately is my R9 290s which showed up with VRM temps.
If your card is pulling less than 250W its probably not that big of a deal. Best way to ensure good airflow over the card is to have a case fan blowing directly onto the card, or just run with the side of the case off and the case laying flat rather than vertically.

Surely if you had a new card and it busted due to the stress of mining it should still be covered under warranty right? It's not as if you've made any modifications it. And if your card is outside of warranty I wouldn't be too worried about it breaking.. you probably could use an upgrade anyway :P

just wanted to add here, it's not always a good idea to open the case - sometimes such as in my box if you have the fans set up for proper airflow there is such a large volume of air moving through that my gpu rarely goes over 60C, and if i were to run without a case in standing air the temps would rise up to 80 or more. just wanted to mention cause unless you've got water cooling or something the case is almost always better left on, as the air moving through the channels of the case at velocity will cool alot more than open air.

Yea I actually opened my case yesterday to test this and I agree if you have good cooling, leave the case closed. I have 1 120mm blowing directly on the gpu and a 220 (or 200mm) in the front bringing more air in and then the two identical fans pushing air out. With the case closed (and my room cold) I run 63-64C.

How loud do those fans get?

My cards are running at 80C +- 3C.

Yep its usually only an issue with budget cases. The 220mm fan should provide a buttload of pressure. It only really becomes an issue with good cases like yours when you start to run multiple GPUs at load 24/7, even the best fans will leave dead spots leading to component heat soak. Which is where an openair convection setup starts to shine, since it provides enough heat to create a nice convection draft over everything. You can even point huge desk fans at it to provide even more movement.

Back to your OP. With your setup I would not worry at all, and as someone said if the card dies within Warranty its fine since they dont say "dont mine crypto coins!" and even if they did they couldnt know that was what caused it.

Not loud at all. I have a air filter that provides constant noise. The case fans don't ramp up since they are plugged into the PSU and not the mobo

It depend on how you use it for mining. You will need to stop for a while to reduce the computer temperature.
