[Used] Colorful GeForce RTX 3070 Ti Graphics Card (Ex Mining) $557.07 Delivered @ MetroCom eBay

1094
REFURB7OCT

One of the best priced second-hand deals I’ve seen out there. Almost 50% off retail.

Don’t know anything about the seller (appears to have a WIP website). More than 10 available at time of posting, and it’s covered by eBay Plus returns. Comes with a 3 month warranty too, for what that’s worth.

Yes, ex-mining. We all talk about the eth-merge bringing down the price by flooding the second hand market. Well, that doesn’t happen unless people actually go for the ex-mining cards.

Seller Description:

EX mining card for half year. Tested working with no issues.
Minor oxidation on the fins of the radiator, some dust but no rust.
No original box, card and 12 pin to dual 8 pin adaptor only.

Original Coupon Deal

EDIT: According to @Grunkun below, he called the customer service line and confirmed that the manufacturer warranty lasts until January 2025.

EDIT 2: MetroCon has confirmed it will supply an original invoice from BPC-Tech with purchase, for warranty purposes.

    Ex miner but damn, that seems like a great price.

      Until it died after 3 months.

        That's such a dumb comment that I'm sure you think makes you look smart but really shows your ignorance.

          • +2

            @edfoo: As someone who has dabbled a bit in mining, there shouldn't be much wrong with most ex miner cards. With my 6900xt, I got the same hashrate at 2.5ghz as I did at 1.5ghz for the coins I was mining, so I just ran at lower frequency for less heat and power consumption. Most miners would be similar as they're trying to maximise profits by minimising power consumption and heat.

            Only thing to really look out for are signs of memory failure as you do get more hashrate from better ram throughput.

            • @DangerNoodle: My main concern is the environment they run in, so many pictures online of these running in a garage or warehouse, years running in a humid environment will be quite bad for the components especially with the amount of air flow going across them

              I would hope they would be using a climate controlled area for their mining

              • @Hank Scorpion:

                I would hope they would be using a climate controlled area for their mining

                Yeah nah. The aim of the game is to go as cheap as possible in the running costs of the mining operations. Things like 24/7 AC will just eat into profits/gains.

            • @DangerNoodle: Miners run the core gently, but wreck the crap out of the VRAM. I can't believe how often this misunderstanding gets passed on.

        • -1

          He's right. Don't listen to spin noobs like linus. Listen to the laws of thermodynamics.

          Running anything 24/7 even if undervolted shortens the cards life.

      • -2

        Saw $140 for 3060. $360 for 3070. $420 for 3080ti.
        Not sure about 3070ti though. I guess $400 is fair.

        • +8

          I think most of the mining cards in Australia have probably been packaged in bulk and sent to countries where they can be refurbished and resold.
          And that's maybe why it's still priced at $550.

          $350 most likely I would pay for ex-mining 3070ti

          • +5

            @grunkun: If anything this is a card brought in from a China/Taiwan mining operation

            • +17

              @Austere: I actually checked with the Colorful customer services using the SN in the photo, this card has warranty until Jan 2025, so manufacturing date probably falls in Jan 2022.

              • +2

                @grunkun: Good detective work. Added that to OP.

              • @grunkun: Just remember though that the photo wouldn't relate to the actual card you're getting as it's for a lot of over 40 or 50+ cards. They may have all been purchased at the same time, but that's just guessing so who knows what the actual warranty is.

              • @grunkun: Recently bought a colour GPU, they actually had the hide to put a sticker on it saying warranty void for mining.

        • where at?

        • +1

          saw a few miner cards evga on aliexpress too but no reviews from the seller. honestly playing with fire lol.

      • Im not against your opinion in its philosophy but think your siggestion is extreme maybe less than $400 is reasonable

      I bot a heavily mined Gigabyte GTX 1080 after the 1st crypto mining crash for 50% RRP. The heatsink was totally oxidised. As soon I recived it I wanted to send it back, but the seller was kind enough to give me 21 days change of mind testing period. I tried out the card and even today I am using it - it boosts like crazy, all I had to do was replace the fans - I replaced it with the 120mm case fans tho for the extra silence.

      My point, I might have gotten lucky or its just that most mined cards wont fail. Its a risk you should be willing to take. At 50% off RRP, it was a no brainer for me.
      If you dont OC it and take good care of it - like undervolt a bit and keep it cool with good air flow, it should hopefully last years.

      If you are a person who would game a lot and average hours/stress per week is very high, a new card would be well worth it.

      • +7

        Possibly mining would weed out the cards that a e going to fail so you're left with the good ones

        • +3

          That is true if the card is looked after well and not overused. Mine was run somewhere in China out in the balcony without any cover/cleaning etc based on the amount of dust/dirt/oxidation it had on it.

      • +1

        Depending on whether the cards were under-volted or flogged (i.e. stock power or above), the things that are most likely to go wrong are:

        1. Fans - replacing these is usually a 30min job, and about $15-$25 of parts from aliexpress (depends on model)
        2. Heatsink TIM material dries out. Depending on your level of expertise, this can either be straightforward but involved (i.e full card disassembly), or sphincter-tighteningly terrifying. Around 1-2 hours.

        The above also happen with old cards - moving parts eventually wear out, and heatsink TIM dries out over time. Mining just hastens it a bit because fans are always on, and heat is always fairly high. I've done both these repairs on my own cards (mined on them for about 12 months total), and I'm not an expert.

        If you do get one of these cards, run Furmark for a couple of hours and listen for any fan rattle, coil whine (hissing and/or buzzing sound), and look at temps. If it survives 2 hours stress testing, it'll most likely be fine.

        • +1

          I replaced everything including fans, thermal paste and thermal pads - did a thorough clearning of heat sink with a rough brush. Not as soon as I got the card, but an year after. It was a fun project. There was so much dust stuck to the card - like 2 to 3mm between VRMs etc, I literally had to scrape it with antistatic brush carefully. At the end, I thought the card wouldnt switch on for how much cleaning and scraping I had done, but luckily it did :)

    • That's a terrible price. It's second hand lol (so at least 50% of new RRP).

  • +45

    Well, at least they’re honest.

    • +2

      agree , at least they honestly say it!

  • +9

    don't buy!!!

    Dunno why it’s been reported for insufficient quantity. Posting guidelines clearly say 10+ quantity is sufficient for eBay listings, which is the case here.

    • +1

      yeah why did they do that?

      • +1

        You think they would clean each one by hand? When theres easily hundreds of them. Thats nice.

        • +4

          I thought they do hand clean each of every one of their cards, pat dry them, wax and polish them, then give them a kiss every night…

          • +2

            @edfoo: They cradle each one and sing it a lullaby.

            • @xoom: Then proceed to forcing it to solve complex maths questions 20 hours a day… until they cardle it, sing a lullaby, then kiss it into sleep. rinse and repeat

    • +1

      Have been very suspicious of used cards looking flawless. Now I know why. LOL

    • +4

      as long as they used isopropyl alcohol or mineral oil to wash with, it should be ok, right? :P

      • Place it in the dishwasher. Top tray. With some finish rinse aid. Should do the trick.

    • +7

      So? As long as they weren't in the mining rig at the time, and they were using clean water then I don't see a problem.

      People use dishwashers to clean hardware: https://www.techspot.com/news/76940-pc-hardware-enthusiast-d…

      • +2

        Water has salt and other minerals left over when that when dried can mess with conductivity. Using distilled water or isopropyl alcohol is way safer. And if moisture gets trapped somewhere and not fully dried can still cause corrosion or shorts. It will probably be okay still but still a risk.

      i saw a video guys that must be the norm

      • Those guys that must be the norm videos are everywhere now😅

    • if done properly wouldnt damage a card and probably cleaner than 90% of gamers cards sitting in their PC for a few years

  • 4060 is here i think soon?

    No box with it…. Only card… Why no manufacturer warranty when its just 6 months old as per the claim made by seller. Its a lie i think… No purchase invoice, no manufacturer warranty…

    • +7

      Not really. The 4080 16GB and 4070 “4080 12GB” are set to release in November. The 4060 probably won’t appear until sometime early next year

  • +9

    3 months warranty on an ex-mining card is pretty poor.
    Wouldn’t risk it at this price

    • +2

      It's 3 months more than I'd expect.

    • +1

      wouldn't you know if it will last or not within 30 days?

      if it fails then it will likely to fail immediately or within 30 days (ie you would know there is an issue), don't think 3 months or more will affect that.

  • +1

    If you can stomach ex flogged work horse. Cause they would have flogged these cards.

  • -2

    Are you sure you not miss type? Like supposed to price as $55, this like buying cars ex taxi that already run 250k km.

    • +1

      more like 750k kms

      • +1

        But but but the odometer reads 150kms only. 😜

    • I had an old ford falcon taxi and that thing was bulletproof no matter what lack of maintenance it had.

  • +6

    Very good deal. And being a mining card the gpu was most likely very lightly loaded if used for eth.

  • +10

    I would risk it for $350

    • +2

      Yeah $300 seems fair now

      • +4

        after last crypto crash around 2019/2020, ex-crypto rx470/480/570/580 were sold in China for around 500 Chinese yuan which is just over $100AUD.

        3 years after with all the performance advancement etc, I'd expect 3070ti ex-crypto be around $250 mark no more.

    • +5

      Nah $250 seems alright (i.e. ex-miner & 3 month warranty). If people hodl more, the prices will come crashing down even further which is good. (because it's a loss for them to hold on to EOL products taking up shelf space)

    • agreed

    If any one wants some insight into buying ex-mining card, Linus has a video about it. https://www.youtube.com/watch?v=hKqVvXTanzI

    • +15

      This comments thread seems full of people who do NOT want insight into ex-mining cards, no matter how it may help them.

      (Personally I don't believe in myths about undervolted mining causing more stress than gaming, myself, but this is close to normal for used prices at the moment, so I'm waiting until prices drop to at least half this price, I think.

      • +1

        I think in general it's just a lot of unknowns about the conditions the cards has been previously used with. Some people running mining rigs are not even educated about how it works, they just let someone set it up for them and have it running without any proper maintenance >.<. Personally for me, a 3 month warranty for an otherwise 3-4 year warrantied card purchased new isn't worth the risk at 50% off price. I wouldn't even risk for non-mined but normally used cards with similar offerings :)

        ymmv.

      • Undervolting should not do anything wrong, but temperature fluctuations and too high a temperature is dreadful for GPUs. If the GPU in mining was undervolted, ran constantly, and ran cool, it should almost as good as new.

        Hard to know and taking a risk I guess.

    • +4

      you think the people here are educated enough to understand?

      its much easier to be a hivemind of people going oooo fk miners card will fail in 2 months.

      This says that performance isn’t degraded after mining. It’s basically a binary yes or no on whether it works.
      However it says nothing in the longevity of the GPU.
      I do think a miner can take good care of a card, undervolting, keeping it clean, etc. to have minimal impact on the card.
      However, it’s a lottery, just like any used product. The person mining on it could take care and I wouldn’t be too concerned. However they might be running it nonstop at full throttle in a dusty, hot box for months. Then they take it out and do a quick clean to make it look good (possibly doing more damage). Putting this much money behind a product which may have been thrashed is too much of a gamble for me

  • +8

    Ex mining cards can be ticking time bombs but they are not as bad as most are making them out to be. Most of the time they are under volted and run at lesser extremes than most enthusiast rigs, but yeah theres still a degree of risk, like there is buying anything second hand.

    • Exactly. Thermal cycling is one major contributor to GPU failure. Configured appropriately, there should be little degradation of the GPU.

  • +21

    What’s with the whole ‘Don’t buy thrashed mining cards’ thing that goes on here.
    Some posts are absolutely fine with people acknowledging that there generally is no more issues with mining cards than non-mined cards and others are just like this saying they’ve been thrashed.

    I personally have had a 1080 since release and mined and gamed on it practically everyday.
    Mining is underclocked and runs a lot cooler, when I game overclock as much as I can and push up in the 80 degree range and still good as new sans replacing the fans as a bearing went but that was $6…

    Plenty of evidence to show ‘professionally mined’ cards run cooler, have used less power and run underclocked than a standard gamer - I’d be more concerned about second hand SSD’s that have been chia mined and actually are (profanity) due to the read/write cycles being maxed.

    Just my 2c but price is good, mining is fine and nothing to worry about.

    • -2

      The difference between you owning a card and doing casual mining on it and a setup of professional, non stop, overclocked mining cards, is that the only care is on the PROFIT of the card, not the card itself. Miners run these at the absolute max to get the maximum PROFIT.

      The risk is in how hard was the card you're going to get run, for the right price you take the risk.

      • +11

        Eh, overclocking and exponential increase of elec cost and replacing gpu cost worked out to be less profitable than underclocking and reselling cards when the run is over.

        I’m more inclined to buy a mining card over one that’s been overclocked and ran at high temps on games.

        • +3

          The best part BY FAR about ETH mining being over, is that I don't need to hear about ETH mining anymore.

      • +16

        Using a card to it's absolute max for mining makes no sense. Most mining rigs are under clocked / volted to run as efficiently as possible, loaded lightly to make more profits and decrease energy costs.

        You would have more issues with a card that has been run for heavy gaming.

    • +2

      Yeah I "thrashed" my R9 280x back in early 2014, mining at very high temps, as badly as the fearmongers in this thread are worried about.

      Much harsher treatment than the undervolting that's by far the most profitable way to mine nowadays.

      It's still running fine almost 9 years later.

      • off topic but that card was awesome for so long

      • You can’t make any solid conclusions from a single sample. The model of card might be more hardy than most or your specific card got lucky.

      • +2

        My R9 270 with a crappy cooler… In a pc case that's basically an oven for over 7 years, pc was on pretty much 24/7… Moved it over to my media server pc and its been running with no issues…

  • +10

    By buying this you are giving the people responsible for the outrageous price of graphic cards and a fair share of pointless global emissions money.

      its a tough gig mate

      • And use case for GPUs in general is for gaming which is deemed non-essential. 🤷‍♂️
