It is a multi split ac, it can have two evaporators and one condenser. Therefore it is a powerful ac, yes an ac can consume 2600w for 2-3hp models.
It is also an inverter ac, the more your room heats up the more electricity that ac consumes until it maxes out its cooling capacity.
Maybe that 9kg is the amount of refrigerant needed in that system.

The only reason why anyone would direct their rig to mine ETC is hoping that the value increase after the ETH merge is successful but you guys have forgotten that ETH forks are coming, they might be a better option than ETC.
See the BTC forks... ETC is a fork of ETH and is the future of POW. Wrong, ETH is a fork of ETC   The only reason why anyone would direct their rig to mine ETC is hoping that the value increase after the ETH merge is successful but you guys have forgotten that ETH forks are coming, they might be a better option than ETC.
ETC rised over the last weeks, and it will continue. I wouldn´t trust this new forks for ETH after the merge - ETC is the original ETH chain, it exist for so long time, with max cap coins, reward reduction after a specific block time and it is the 3. biggest PoW network at the moment. ETC can be ASIC mined. ASIC manufacturers will pump it to sell their miners hehe |

how about the bus width? it made the difference between 3080 and 3070ti. if it is the same as 3070ti bus width then it is worth it. plus you have to get the 3 fan cooler/length models, because you might not be able to max out those gddr6x's hehe Even with the three fan models some are bad build and 3070Ti are known to always have high memory temperature issue after few months of intense mining, be ready to battle with cooling pads. The manufacturer of video cards with DDR6X memory turned out to be smarter than all the miners. All these video cards are not designed for mining, and even good models, which were mined for the first 6-10 months without overheating, then problems began. Thermal pads need to be replaced which will void the warranty.For video cards with DDR6X memory, good closed cases are needed. yeah maybe they did it on purpose. thermal pad or thermal paste, it won't last for 3 years, even for gamers. their terms are evil hehe. on the other hand if the cards can mine for a few months (before you change thermal pads) there is a 99% chance that those cards are good to go for years (even past their 3 years warranty). warranties BTW is added to the total cost of the card, like insurance cost. |

Hi everyone, what do you think I should add to my list? I have been mining for year now and I have got all the coins I want so what do you think I should add to the list? Here are what I have already and the coins that aren't PoW also are mined through unminable, forget ETH as I have enough
1. Gala games
2. Ecash
3. Flux
4. Shiba
Do you not consider bitcoin one of the main coins you should hold? Honestly I'm surprised when people list these complete garbage coin lists and forget to list bitcoin. Was that by design or just sheer ignorance? Honest question. Most likely reason is that bitcoin is just way too expensive. There are some people that think you can only buy a complete coin and can't buy partial amounts similar to stocks. So most people cant afford to spend $25K on a single coin. Another reason is that people want to make >500% gains. How much can you make off bitcoin now? It might double or triple. If you invest $500 into bitcoin you will only make $1000 profit if it triples. People want to invest $500 and come out with $50,000. So they invest in all these small cap projects. Agreed, the misconception that bitcoin is "too expensive" is kind of funny. I'd say most of these low cap coins that are pennies or less are way to expensive right now. I'd like to think there is still more then 10 fold gains to be made from bitcoin still with low or limited downside risk. Kind of a no Brainerd at this point but to each their own. Having 2 btc and 100,000 doge is a decent mix. Aaaaaaaanndd mooooorrreee GPUs |

probably a work place where electricity is "arguably" free. if it is, then yes it is profitable enough, the question is, is it worth the hassle?

My answer is NO, that's a high risk investment plan that can land you in a big trouble, the first mistake I made with crypto mining is leading some money to buy graphic cards, the first time I started building the rig I mistakenly killed a GPU, it was a disaster, and later bear market ruined everything, I paid the debt two years later and that's because the person that loaned me the money understands me very well, if not it will be more disheartening.
You took the loan at a wrong timing it seems, if miners bought graphic cards in 2020 around November they would have made a lot through out 2021 and ROI'd with extra gains on ground, this is what a perfect timing looks like, in the end you will be able to pay your loan and be a proud owner of a mining farm or rigs. also think about the loan "interest" as an additional "electricity cost" to make things simple if your electricity is 0.04 now it is 0.08 putting loan interest in mind. yes it is profitable in a bull run. "timing" is a gamble too. make sure you are not 100% into that loan, make sure you have a hedge. |

the interest is like electricity bill that needs to be paid.
it can be ROI'd if you time it right just at the start of the bullrun. in crypto timing is everything, and yes it is RISKY.
if you made money (you level up in crypto) just stop with loans and debts. pull every money from your pocket.

These video cards can no longer be found on sale without serious problems. The 7970/280x video cards have 3 GB of memory, the 290 video card has 4 GB of memory, which will not allow mining some modern coins, and these video cards have very high power consumption, which is also a problem.
Still better than a heater, power consumption is heat generation, the more power consumed the more heat generated, these cards can still reduce cost of heating if you are in a cold climate and the newer cards are still overpriced hehe. Even better if you already own them. Do you seriously want to make a heating system out of 7 year old graphics cards? With the current profit and problems with old video cards that have a memory limit, I would not do experiments. Do you suggest putting these video cards in a special liquid? If the cards are 7 year olds, the motherboards that they plugged in are teenagers LOL. No they are not going to explode, just plain air cooling will suffice. Even if the profit is negative 3 usd, with zero hash rate heater your profit will be negative 7 usd, you will save 4 usd..that is good enough. |

By the way, as i pointed out in other threads, 3080, 3080ti, 3090 with lower end coolers even with the best thermal pads/paste is like buying 290/290x where there are no improved coolers available vs buying the 390 and 390x with improved coolers.
The only exception is when you are in a cold climate area, the low quality coolers can suffice.
This is also what made this 7950, 7970/280x the best mining card because it is the best mining card in all climate temps.

They mined for years and stored for years..they were not the ones you are saying..
There are different batch with different vrams, hynix and elpida that hashes differently too..maybe there are bad batches for the unlucky ones.
I played with the 290x too..
This is what i'm comparing the 280x to 290x...in terms of present day
280x is like 3070 level of heat with the performance of 3080ti vs the 290 (3090) and the 290x (3090ti).
They are going back to the storage though because i have more profitable cards for the space, electrical space, and heat space.
About "for parts only"...yeah this is a must, i have a 3080ti screw that fucked up because i used a lousy screw driver...you know what, i got a replacrment screw from some old 390 lol.

cleaning up some of my storage stuff.
played with two 280x sapphires.
both burned something in the board, lighted and smoked....aaand it both runs.
4 screws, you clean and you are good to go...with just 4 SCREWS!
Let me guess. Is this the Dual-X Sapphire R9 280X? Yeah I had the same issue. Started to mine ETH with one years ago. All of a sudden came home with rig turned off. Started it back up and poof. Opened it up and some MOSFET or some VRM had burn't out. So I desoldered it for fun. And started it back up and it worked. Undervolted it and underclocked it. A few days later another MOSFET went. So its been for parts ever since. I gamed with it for a while and it was fine but as soon as I tried mining ETH, it completely went up in smoke instantely. yup, dual x surface mounted chip capacitor or resistor that was burned, i say they might be in a better condition than mosfet or vrm burning out there. |

My 3070ti is doing 80.68MH in hiveos, you need to find the right OC for your card, mine works stable at 2600Mhz Memory clock while someone I knew very well can't get his 3070ti to 2400Mhz without crashes.
Many miners use different memory settings for video cards from the same batch. If you are lucky, then one or two video cards out of 10 will mine 76-77 megahash, but the main thing is that the memory does not overheat. Not all of these video cards work stably at a frequency of 2600 Mhz i found in my country PNY GEFORCE RTX 3080 - 12GB price drop to around 750usd this card is good for mining or pick other brand is better? How much do 2 PTX 3060 Ti graphics cards cost in your country? Most of the RTX 3080 video cards have memory heating and hashrate drops. This is solved by replacing thermal pads with thermal paste or buying a good closed case. I would not advise you to buy this video card first for mining, if you are not an experienced miner. There is another solution, but a lot of miners don't see this or don't want to pay extra. Gpu models with better coolers are a bit more pricier because not just the coolers but also the higher clocks. For example i have 3080ti suprim x and gaming pro, temps are not even close. 3080ti palit gaming pro width is smaller (1 inch) than zotac 1080ti amp extreme, the weight i didn't measure but 3080ti is even lighter That 1080ti is even cooler at 300w than that 3080ti at 300w. Watts is watts = heat. My standard for coolers for gpus that can pull 300w is like that of zotac 1080ti amp extreme, the msi suprim x exceeded those, they are better. So the problem is not in coolers, but in thermal pads, so the memory overheats and the hash rate drops. After replacing the thermal pads, the problem is solved. If you use the fans at full capacity, it will break them. The problem is not always solved by buying expensive video cards. There are a lot of things to consider before building a mining farm. Yeah, thermal pads are problems but even if they can transmit the heat a 100% (no loss), you will be limited by the heat sink(metal quantity and airflow design). Even if you use the best of the best thermal pads and the heat sink is just 100grams of metal, you are not going to cool those cards whatever you do....maybe by putting them infront of an AC will do lol. Here is an example: 290/290x, when they are released the coolers are not enough, then same chip (refresh) 390, bigger cards, bigger coolers then the true potential of 290/290x are realized. I had R 390s and they were very hot too. But they were much better than the R 290. But if we are talking about heatsinks for the 3080ti/3080, then these models have high-quality cooling, and when replacing thermal pads, the problem with the hashrate drop ends. Not all have high quality cooling, palit 3080ti gaming pro is one. Just pointed it out that there are 1080tis that have better coolers(bigger) than some 3080ti, they are all good enough but in mining where you are reaching the temp limit of your mining area, you may have the chance to add 3-5 more gpus compared cheaper coolers (the room might get a bit hotter but the cards can handle it). I just observed, didn't look at the datasheets but 1080ti core is hot vram(gddr5x) is not as hot as gddr6x, now 3080ti, core is hot plus the vrams(gddr6x are hotter than gddr5x), imagine that 3080ti has a smaller cooler than the 1080ti. The 3080ti suprim x has exceeded the size of that 1080ti..suprim x is a superb cooler. |

Maybe it is more profitable when ETH becomes POS because those majority who only knew how to mine ETH will leave, and the profits will be shared among hardened shitcoiners hehe
