1gnoirents posted:Also I've been seeing videos pop up about using liquid metal pastes on GPUs to great result on Pascal cards, might be worth looking into. I'm going to be testing that on both a Gigabyte 1080 G1 (pretty poor fan performance overall) and a EVGA 1080ti SC2 ICX today or tomorrow and see what happens. I have some leftover from Haswell delidding days It does work but like all liquid metal it's conductive so if it spreads out to the discretes and shorts something you're hosed. And some of them are pretty tricky to apply properly. I don't think the gains are remotely worth it. You see big gains from repasting. Factory thermal pastes are not very good compared to aftermarket stuff and often end up pretty dried out after a while. But there's no reason to use liquid metal instead of just some Gelid GC-Extreme or NT-H1, and some pretty big risks/downsides. Pretty sure those videos were sponsored content from the companies who make liquid metal paste.

Cygni posted:Yeah, especially considering you can get a 3-ish use tube of ceramic ArcticSilver 5 for $6, and a single serving of something like CoolLabs Liquid Pro is $25... and the CoolLabs stuff is conductive and only cools like 2-3 deg better than AS5, ehhhhhhh This is really what it comes down to for me: like absolute best case liquid metal makes a 5 degree difference vs random thermal paste, and against good stuff ($10 a tube instead of $5 a tube) it should be <3 degrees. It's just not worth even a trivial chance of killing my card over three degrees. I am very serious about that whole video being sponsored content from CoolLabs, I'm pretty sure it is. It makes no damned sense to use liquid metal on a bare die when they cool so easily on AIOs. Most people are too chicken to open up their GPU anyway and then on top of that you need to be super careful not to short out your card? Why the gently caress would you not just buy an AIO bracket and call it good? That's going to make like a 20-30 degree difference in your temps, gently caress 3 degrees. And if you're looking to throw money away, get some Noctua fans to go with it. They are expensive as gently caress (literally $20/fan) but they are legitimately super good fans. (I actually got a Noctua 120mm fan for my G10/H75, will be waiting a few more weeks for the Gelid VRM bracket to show up but... I'm tempted just to assemble it and go. My 1080 temps are getting really bad as the summer heats up, and I think my thermal paste is dried out pretty badly from mining on it for a month. Even at 90% power limit/100% fans I'm at 80C.) Also, Liquid Pro in particular is supposed to be loving awful to deal with. It's really liquidy, whereas the Liquid Ultra was a little more viscous.

1gnoirents posted:Keep in mind guys a huge glaring factor last time with the 290 purge in that during the mining craze it went from a $600 card that was worth $600 against the competition (780ti, although not really, but still) to barely being competitive with a $300 card (970's hit $300 when it all went to hell). I do believe the main reason was huge supply of course but I wouldn't hold your breath trying to pick up 1080's for $200 next month. 1070s were dropping below $300 at times before they got bought out a month or so ago. 1080s were flirting with $400. I'd say 1070s are going to end up at $200-225. Since miners didn't buy up 1080s prices aren't going to tank as immediately/drastically, but they are still in the same market. And the 1080 in particular still isn't quite enough for 4K, it's a 1440p card still, so it's very subject to substitution by 1070s if the price is too high. I would bet we see $300-350 for 1080s after all of this hits the market. A huge amount of those mining cards are 470/570 and 480/580 so those are going to be the prices that tank hardest. I wouldn't be surprised to see 480 4 GB models hit $100 and 8 GB models under $150. That's basically where they were before the mining bubble, but I think there's pretty good demand for them from gamers at the $100/150 price points. I would be very curious to watch a graph of new units sold over the past 2 years and over the next 6-12 months.

Herman Merman posted:Otherwise correct, except that earning $ from buttmining isn't economic growth. Keynes' famous example was burying bottles of money and letting private enterprise dig them up, which is basically the same thing conceptually as mining. You can view the whole scheme as a form of stimulus from the "government" of the coin, as encoded in the rules the client follows regarding generation and distribution of currency. Some people believe that government spending inherently displaces private spending in all cases, which probably isn't true, especially when a currency is just being issued and "the government" owns 100% of the money supply.

Methylethylaldehyde posted:Sever, sell your card now before the entire butt-economy collapses. The window to sell your cards is closing almost immediately if not already closed. 480/580 prices are down 25% from peak bubble prices on eBay. I guess it'll be even lower in another month, but now that prices are plummeting you are at higher risk of buyers backing out of sales or refusing delivery when they see that prices have dropped $100 between when they ordered and when it arrived. eBay BIN and Craigslist are going to be tougher to sell at, and Auction format is going to push your sale date even farther into the crash zone. RX 470/480/570/580 cards and "oddball" cards like Fury and 390 are going to collapse sooner and harder than 1060s and particularly 1070s. Might still be a little bit of a window left on 1070s but not much. Party's over.

MaxxBot posted:I still don't understand the crypto market fully, what would make the decline pause like this? Looking at the difficulty chart for ZCash it was steadily going up for a while but seems to have leveled off. Profits have declined to the point where people are no longer comfortable buying new hardware, I guess. poo poo seems very weird right now, there seems to be a lot of uncertainty about the Segwit2X patch (a relatively large conceptual change being deployed onto a 'production' system), to the extent that when it looks like it might kick in the prices dive, which tanks the price enough that miners move to other currencies. There might be a degree of capital flight from Bitcoin to other currencies, but normally Bitcoin is the anchor and other coin prices move against Bitcoin rather than against USD. When Bitcoin goes up and down, the other currencies move up and down proportionally (in USD) as well. It also doesn't help that Ethereum is going through a huge change to their core algorithm too, and there's some real questions in terms of security with larger pools (not majority but plurality) who might be able to do stake-grinding rewrite attacks.

IMO now that you're looking at a ROI timeline of 6+ months there is no longer the massive demand to build new rigs, so prices are slowly drifting back to normal. However coin prices have remained high enough that we haven't seen an outright popping of the bubble either, people seem content to crank away at $2 per day or w/e. (the Ethereum network hashrate has continued to increase at a pretty good clip so 6+ months ROI is effectively "never")

Smoke is beginning to pour out of Bitfinex (particularly due to their Tether scheme), if you are only in it for burritos rather than THE MOON you might want to consider cashing out at this juncture. My passive mining paid for a good chunk of a new NAS so I'm pretty happy calling it quits. Of course who knows with Bitcoin, it'll probably double in the next month just because I cashed out.

Or it could be nothing - the market can be irrational for a long time (famously, longer than you can stay short).

Knifegrab posted:I am so loving confused now. I thought that my machine averages .5kWh meaning every hour it uses 500 Watts. so that is to say underload my machine is rated at 0.5 kWh. Think of watts as being a rate of power consumption, while watt-hours are amount of power. Consuming 500 watts for one hour, or one watt for 500 hours, means you have consumed a total of 500 watt-hours of power (and a kWh is just 1000 watt-hours of course). The other way you can measure power is by current (the voltage is implicit - often either grid voltage or the voltage of the battery). So you could give the rating of a battery in amp-hours - if you have a 3 amp-hour battery it could sustain a 3-amp current for one hour, or a 1-amp current for 3 hours. Power = voltage x current, so you can see that higher voltages let you deliver more power with a given amount of current (and current is what causes heating in connectors/wiring/etc).

You can safely use average for solo coin mining however because you can control what power you are expending for your 'somewhat' determined reward. Yeah, mining is not the best for hardware so hopefully you are not riding real close to the edge of profitability such that one coin pulling 10% more power than another is going to push you into the red. Otherwise you are just buying bitcoins in a roundabout fashion, while wasting electricity and burning up your hardware.

Do people find that risers are actually reliable? I tried them once, I did all the usual stuff (turn PCIe speed down to 1.0x, enable 4G+ addressing, etc), and I was still getting maybe a 48-hour MTBF with 4 or 5 GPUs on a board. Honestly it seems like it makes more sense to go with fewer but faster GPUs and to not use risers.

The general idea of the paper wallet is sound, but there is no reason to prefer a real paper wallet over a properly sandboxed Linux VM instance that you spin up, generate a wallet, and then shut down and encrypt with a strong password/keyphrase/keyfile and back up. Even then, there have been exploits like the Debian SSH keygen turning out to only generate 32768 different keys (a similar vulnerability occurred on some phone wallets). If something like that happens you are hosed regardless, there is no fix for accidentally generating predictable keys.

Alzion posted:While mining with a 1080ti I've noticed that Winminer is doing 55 MH/s mining Vertcoins. But, when I use my own CCMiner2.2r2 I pull in 67 MH/s. Does Winminer have a reduced intensity setting on their miners for default? It may just have decided that it wasn't a profitable option at that point in time. Coin prices have been spiking around really badly, yesterday I saw Vertcoin as high as $6.50/day and as low as $1.50/day on a 1080. I get the feeling some of these Captains of Industry are still trying to figure out how to use a regular miner and don't have enough hysteresis set up. Yesterday I saw a pool with 300 MH/s on a network with ~1200 MH/s, and the pool hashrate would periodically bounce up to 2500 MH/s for 10 minutes (i.e. that one person had 64% of the total network hashrate), presumably at that point their miner told them that coin wasn't profitable anymore, and they'd bounce to another coin. A lot of the small coins don't really have much depth, and like one warehouse full of GPUs can run the profit into the ground.

DrDork posted:If you're a small-fish miner, in most cases you should be appending /0 to your wallet address. This will reduce the difficulty, which has the end effect of increasing accepted shares and upping your payouts. Also don't mine to like 10 different pools at the same time, since it'll just mean you're not earning shares efficiently anywhere. From my understanding, the difficulty you specify (including with a "d=xyz" password) is just a hint and the stratum will adapt to the shares you actually push out. If you have multiple machines going it would behoove you to run a stratum-proxy for things you are mining on a lot.

Pascal is already way more efficient at mining than Polaris, Ampere is going to be beastly when the chips are down and profits are low.

craig588 posted:I don't know AMD so well, but Nvidia DGAF about mining and kind of doesn't like it. Miners are buying gaming segment cards, but instead of gamers they're only buying cards based on a nebulous profitability rather than every generation to play new games. They'd rather have consistent long term sales from gaming than miners using up all of the supply now. Miners buying cards now makes it harder for them to build mind share with new customers when the narrative changes from "These cards are good" to "These cards are good, but overpriced". When kids are at the 8-13 age they're not buying anything directly but brand affinities are getting built subconsciously that pay off in 5-10 years. That's the Nvidia and Nvidia partner stance, I don't know people at AMD and partners to get their comments. NVIDIA makes enough cards that miners can't really buy them out the same way they can do AMD. It's a fringe benefit of their crazy market share. Dunno, if they wanted to fix prices they could just ramp production a little more. Mostly they just need more 1070s, 1060s are a little on the high side but not terribly far out of whack, and the 1070 Ti is bang-on at MSRP. I kinda think NVIDIA likes this new world where they can sell at/above MSRP for an entire generation at a time. That probably goes for AMD too, but they are clearly afraid of repeating their mistake with the 290 overproduction when the bubble popped on them. But again, the fix is just "release a newer and more efficient card", boom nobody cares about your old cards anymore. A big part of the problem comes back to AMD's habitual rebranding and lack of R&D spending. AMD definitely gets the poo poo end of the stick though, they are just perpetually out of stock on all their products and Vega is a turd apart from mining (bearing in mind its huge die and insanely expensive VRAM subsystem) so they are extremely vulnerable to mining popping if prices collapse. At least they've been able to keep 580s in stock this time, even if prices are out of whack again. Lisa Su said a "single-digit percentage" of their sales are from mining, I think there is some serious lying-with-statistics going on there. Maybe single-digit percentages of AMD's total revenue, or including OEM sales and poo poo. It makes up a huge percentage of their retail add-in-board sales and probably >80% of retail Vega sales (easily 99% at the moment, given current pricing).

Craptacular! posted:Is TSMC even going to make more 1070s because I figured the ti was going to be a defacto replacement. It's basically a repurposed 1080 that didn't quite pass QC, in the same way that 1060 3GBs were chips that had one CUDA core fail and were repurposed instead of being thrown away. The 1070 was basically it's own unique manufacturing, so I figured it was effectively retired in manufacture and the plant would focus on making 1060, 1080, and ti fabs. Yields probably favor going with the 1070 Ti nowadays but to be honest die-harvesting is always a racket, literally everyone gimps functional chips in order to fill demand for downmarket SKUs for both CPUs and GPUs. Once you get past the initial launch phase yields are always great, but people want lots of the cheap chips, and you don't have nearly enough actually broken ones to fill demand. If they want to retire the 1070 then fine but then don't turn around and bitch about losing mindshare after you've left a giant void in the extremely popular midrange of the market. Or, drop the price of the 1070 to fill that space. Right now there is just nothing between $260 and $450. (also, the way it works is that 1060s are GP106 and 1070/Ti/1080 are all on GP104, it's the same die, you don't try to make 1070s it's just what is left over when you try to make a 1080 and it is partially broken. 1060 die-harvests become 1060 3 GBs.)

Nitrousoxide posted:Aren't 1060 and 570's the better mining cards at the moment though? You loose ~20% performance but cut your capital costs by almost 50%. They have a payback of 2-3 months instead of 6 months. This reduces your exposure to the risk of the bubble popping and you can just buy more 1060 or 570 cards to get the same hashing capability at a lower initial expense but slightly higher physical space requirement and a tiny increase decrease in margin due to higher electricity costs The rest of the system costs money too, though. At current prices yeah, the 1060 and 570 make more sense, but if you could get a 1070 for $375 or so there would be a reasonable argument for it. Frankly the 1080 and 1070 Ti are not a bad deal for miners either, just not for ethereum. They're roughly twice as fast as a 1060 at Neoscrypt and Equihash, and basically cost twice as much, so performance-per-dollar is the same and you are getting more bang out of the rest of your system. And if the market dumps they will be better for gaming, and probably less susceptible to market flooding. It's basically just the 1070 that is drastically out of whack.
