Where’s the best place to actually find these cards? When I see used cards on say Craigslist they always claim “never used for mining” or similar, is there a way to verify that kind of thing?
- capableweb 4y agoWhat's the problem with cards that been used for mining? People say that they are in worse state than other second-hand cards, but I'm not sure that's true. Most if not everyone I know who uses GPUs for mining undervolt the cards as it's more profitable, while everyone I know who is a gamer run their cards overclocked. So in theory (but someone please correct me if I'm wrong), with that in mind, you should prefer cards that have been used for mining and undervolted, rather than cards from gamers that have been overclocked.
- smoldesu 4y ago> Most if not everyone I know who uses GPUs for mining undervolt the cards as it's more profitable This is true, but it doesn't mean that the card runs any cooler. Yes, for mining it makes perfect sense to run it at a lower voltage. That doesn't stop your VRAM from getting pinned at 95c, and if you do that for long enough then it won't matter how hard you underclock your GPU. The clock speed doesn't directly correlate to your hash rate.
- ulrikrasmussen 4y agoLinus tech tips had an episode on it, and largely found that the performance degradation was insignificant: https://www.youtube.com/watch?v=hKqVvXTanzI https://www.youtube.com/watch?v=hKqVvXTanzI He did however note that the cards that he tested had been used in a relatively clean and dust-free environment. The biggest risk to buying a card that has been running 24/7 for years is that the cooling system is busted due to build-up of dust.
- GaryNumanVevo 4y agoUsed mining cards are definitely worse, the VRMs are usually destroyed and they're typically missing a couple VRAM memory modules as well

- lostmsu 4y agoI would not trust anything coming from wccftech. That particular article is probably just an advertisement for some shitty software that promises to fix your broken GPU.
- nharada 4y agoI might not mind for the right price, but I'd like to at least know. Right now it seems that either (a) nobody is yet selling used mining cards or (b) everyone selling used mining cards is lying about it and trying to sell them at the same prices as barely used cards.
