This chart claims that R9 280x's are just as good as 7970's for litecoin mining.

If I'm to believe this calculator, an R9 280x does roughly 10 litecoins per month, which are "worth" $35 each, so that's $350/month. At load, the Asus 280x draws 350W from a typical system, so for a typical cost of $0.20 /kwH, it's $8.40/day or about $250/month, or $100 profit.

Unless the litecoin price keeps going up and the bubble inflates for another month or two, this whole exercise seems even stupider than at first glance. You have to believe that this nonsense will go on for another 2-3 months without even factoring the cost of all of the other hardware if you're buying computers just to mine, or paying a $200 premium for cards makes no sense at all. If you're a sane person and just want to do it with an existing rig when you're not gaming, ehhh.
Litecoins will trade much higher than $35/mo over the next month, I guarantee it.

It's one of a variety of bitcoin-alikes that use a modified client and a different block chain. There's an exchange rate for it and all that poo poo, both between it and other *coins, and between it and actual money (though good luck getting large amounts of money out if you happen to strike it rich in *coins). Bitcoin was the first and as such the technologies built up around it - first the big switch over from CPU-based to GPU-based computation, then the switch from GPU-based to ASIC-based computation (bitcoin ASICs are dramatically more energy efficient than GPUs while still offering competitive hash rates, which means they have a much higher return on effort put in as the difficulty goes up).

Litecoin was designed to be more or less impossible to mine with ASICs any more efficiently than CPUs, but it still is more efficient to mine it with GPU than CPUs, thanks to a happy accident (GPU companies aren't making cards for bitcoin poo poo, their developments toward GPGPU computing just coincide with stuff that works well for coin mining since all it's doing is slamming hashes up against one another to get collisions with an arbitrarily set difficulty, something that is easier to do for GPUs than CPUs). Litecoin isn't AS exploitable by parallelization as Bitcoin, so instead of a 100x (or greater) improvement by using a GPU or ASIC to mine with, you see instead a 10x (these are fast and loose numbers, but hopefully you get the idea).

The thing is, there's a bubble right now pushing Litecoin prices up. It got a GPU-based mining client not too long ago, both for general OpenCL but also for a CUDA-specific version which actually makes nVidia cards moderately competitive with AMD cards for hash/watt/second - a 780Ti can achieve 2/3rds the efficiency with the CUDA mining client as a R9 290 gets, compared to more like 1/8th before. But the whole "deal" with it is that GPU mining is suddenly profitable, so miners are buying up GPUs left and right since economics be damned, the price on these things never go down and it totally isn't funny money or devil fiat currency etc. etc. etc.

It looks pretty profitable on paper to be mining litecoins right now, but basically nobody cared about them until now and then all of a sudden literally every US consumer outlet is out of stock of AMD cards, so it's going to be amazing to see what this does to the difficulty.

I have a feeling https://www.btcchina.com also started trading in it, which I believe is the reason for LTC having a spike in the first place - Chinese investment had the effect of making the thing skyrocket.

Eh, I don't have money invested in it, I'm not saying "GO BUY CARDS MINE LITECOIN HURR", but I can totally understand why people are doing it, especially if they have free power.

It's easy to joke about and dismiss, but I guarantee if any of us knew how high Bitcoin was going to climb, you'd have been burning up your house with graphics cards.

Because they devalue their currency. It's all a bunch of silly numbers, and for those who managed to see what was happening, they'll be rich, regardless of method.

It's not like the bankers on wall street had to work hard in the traditional sense for the money they created, they simply made more loans and then said they had the same amount again to lend out. Then, insured themselves against the losses. Worked out really well for them, and we got shafted.

Mt. Gox doesn't support Litecoin trading at the moment, but large exchanges like BTC-E do.

For shits and giggles, I decided to do some mining until I ship out my 7970GE. I set it up w/default setting, and threw my Core i5 3570K into the mix as well. In the last 11 hours or so, I've mined 0.12 Litecoins, which at current exchange rates is worth... $4.24. So in one day I can make $9.25, and over a month I can make about $250 after power.

Oh please do tell , even in PM if you don't want to start a derail.

Heck, I'm right there with you. I have it all planned out to convert my Prodigy to a CLC festival by Kraken G10-ing or The Mod-ing or getting an Arctic Accelero Hybrid. This would involve not only the CLC and mod work, but I'd have to swap my BR drive for a slimline model with bay adapter to allow for the size of a top-mounted 120mm CLC (with, of course, a Noctua fan). At this point, I'd have maxed cooling on the Prodigy, practically - a 230mm Bitfenix Spectre Pro intake, and 140mm and 120mm Noctua-equipped CLCs as exhaust. Only thing beefer would be, perhaps, a full custom liquid setup with dual 240mm radiating loops, but I want 3.5" drives and an optical, dagnabbit.

If only I could afford this.

--

On that note, I actually looked into Litecoin mining last night, even to the point of setting it up and hashing a couple work units to get a real-world benchmark of my costs.

The biggest limiting factor wasn't actually compute; it was the distribution of workloads. My 680 cleared a workload at 600 KHash/hour, but with all the transmission overhead, I was actually pulling only ~126 on average. Apparently my post-tuning results never would have gotten much past 200 KHash/hour. Part of my profitability assumption was that I'd only be able to cash out half the "value," so by that measure, it was so barely profitable (maybe $15 a month with my current power costs) that it wouldn't be worth the noise.

I may return to it once I move back to school, because 1) utilities are covered by loans, so cash flow won't be a problem, 2) a high first-month bill means I could mine the first month then stop, and enjoy a little extra grocery money that'll only take 40 years to pay off, and 3) if the coins stayed profitable, it'd help with summer expenses (during which I get no loans and would not mine).

Not to turn this into Litecoin chat, but I set up the CUDA Litecoin miner on my GTX770 during a break at work. Looks like I can get .11 LTC a day which works out to ~$5. Since my utilities are allocated across my whole building and I never pay more than $60 a month, I don't see the harm in running it. Don't think I'll hold on to them, though. I can't imagine this will last too long.

I could manage an average of about 2kh/s/w with my 780Ti, higher if I downclocked the memory, and I still don't want to do it because I'm not fronting that much real money in electricity costs to speculate on *coins. Yesterday it bubbled and bounced. That's, like, all these markets DO. They're the fastest form of naked capitalism I've ever seen, it's commodities trading in bizarro world.

I was going to go in with FactoryFactory because we could both use some spare coin (ha ha ha the joke is ...) but I pay for my electricity and I'd be fronting like $250+ the first month and just hoping it doesn't crunch, which it should, though it probably won't because these people are fruitbat crazy.

These are litecoins and the 290 is pretty decent at it (about as much faster than a 7970 or whatever at this as it is at doing anything else, as you'd expect), much more efficient than the 7970 etc. at the same time too, and costs the same. No GPU is useful for shitcoin mining any more...

Oh, no, I totally agree. I don't really see all this cryto currency as actual money, but as some kind of other investment. It's risky, because people could realise it's all just been created by a bunch of nerds in their homes, but at the same time, as with bitcoin, it could go up in value, when people see it as a way to move something of accepted value (between some parties) for nothing, avoiding tax structures and conversions between two curriences. A bit like antique you thought was useless, but it turns out was worth a bunch.

In the end, who knows. But people always do crazy poo poo with their money, and sometimes it works out. I just think it's kind of interesting to know what the deal is with it all.

Litecoin was made to be more difficult to mine via GPU, which is good for some loving reason. Turns out it's still way more efficient, just maybe an order of magnitude less so, to mine GPGPU than CPU. Oops. Now there's also Primecoin, which REALLY, HONESTLY, PROBABLY, can't be optimized to perform better for wattage on a GPU than a CPU.

These things get made to fix "bugs" in the old system, and to create new ... how to describe it, new ways of approaching the imaginary problem of "how do we create an electronic currency that starts from nothing and builds to something?" The emergent problem that Litecoin and Primecoin address is that Bitcoins, even as difficulty raised up, became too easy to mine, leading to things like the 51%-ownership vulnerability, or the ability to throw a shitload of integer-specialized ASICs with a microcontroller all working in parallel to work off of 500mA at 5v via USB instead of hundreds of watts via PCI-e making what was supposed to be a "currency for everyone" into a currency for the few people who can afford to heavily buy into the requisite hardware to make them.

The other reason that new *coins get made is because the blockchain for old *coins is so damned complex that transactions can take a really long time to validate since it has to wait until a successful hash collision occurs and propagates through the network for verification.

They are traded in the same exchanges, but they don't exist on the same network except in the simple sense that the internet is a big network.

I am hardly an expert on this stuff, you're getting the accumulated knowledge of one night figuring out whether it'd be remotely financially feasible to front real money in electricity for the potential that idiots will just keep percolating this strange commodity. There are probably better people to ask, better places to look, for in-depth information.

Yes, bitcoins still exist and are still sort of the de facto top-level funny money because people pay the most for them, they've been around the longest, they have the highest difficulty to produce new ones, and a primitive infrastructure has sort of developed around using them for things (which is being borrowed from for the other *coin thingies, as they either grow in popularity or don't). Litecoin was made to solve some big-picture issues with bitcoin, and primecoin is the logical conclusion of taking the basic idea of litecoin - "make it harder to mine via GPU, start a new chain but separate from bitcoin so that people can mine the currency without having to hyper-invest" - and delivering better on the concept.

But it's always going to retain the basic flaw that it's just as stupid and "fiat money" as regular money, it just doesn't have the backing of the global financial system, which has the backing of world military force, all tools that ensure that things like the ten-year T-note are actually worth something. These are worth something because THEY SAY SO, and that's pretty much it. Their ideological criticism of fiat money applies to their own money, except theirs is worse, because nobody with a gigantic army, navy, air force, and a stockpile of nukes insists that people will use their currency thank-you-very-much.

Audio over DVI is 1000% non-standard and depends a lot on who has bothered to do what custom and proprietary bullshit.

Why is HDMI-HDMI shitlooking when DVI-HDMI is not? It's the same video signal.

I have absolutely no idea, it looks completely different when using the DVI-HDMI cable. It looks closer to what the image is SUPPOSED to look like (ie 1080p image with 1:1 pixel mapping) but it's still off by a bit causing some image issues, especially with white text on a black background.

Going HDMI to HDMI has a very blurry image and the pixel mapping is nowhere near 1:1 and I have to use the underscan settings to fix the image. Fuckin cheap chinese TVs man, I'd save up for a better one but I've got other priorities at the moment.

My fix for this has always been using a DVI to VGA converter, using the TV's VGA port, editing the EDID using phoenix to make it support 1080p (and think it's the native resolution) which produced a near perfect image. I can't do that now though because the R9 290 doesn't support it.

This is super edge casey though.

Can't you warranty it because the audio interface died? If you made the original purchase on an Amex Card, you also get an extended (doubled) warranty period.

The audio interface is like 3-4 years old now and has had some issues for a while now. It would freeze, then the audio would go out completely. My computer would crash if I unplugged it/plugged it back in. Right now it caused a crash when switching songs, my computer wouldn't even boot with it plugged in.

I'll try fiddling around with drivers but my suspicion is that it's dead.

Uninstall old drivers> turn off pc and install new card> reboot and reinstall latest drivers

Should work fine after that.
