Cryptocoin Mining?

[Attic]

What the bolded all about?

Something from that link I liked.

The ballpark value for the normal hash rate for Tahiti based cards is around: (Shaders * GPU Clock in GHz) * 0.34 >> (2048 * 1) * 0.34 = 696kHash/s.

That would be for a 7970/280x at 1000 core/1500 mem. Most stuff I've read says 1020 core 1500 mem is the sweet spot for 700Kh/s. Some folks run that and get <600Kh/s, likely due to memory type (not speed).

This forumla is based around the card having memory timings correct, the only guaruntee that memory timings are correct (optimal for hasing) is if the memory is the Hynix AFR type chips. The worst chips are Hynix MFR, and Elpida is in between.

The formula also gives a good ballpark for what you can expect out of 100mhz of increased core speed (based on 700Kh/s at 1000/1500), ~70Kh/s. Getting around the 700 mark with minimal wattage I think makes more sense than pushing core high with increased volts.

This could be part of my problem with the 7870LE from Power color. It comes with stock memory of 1500mhz but I bet the latency is super high. It runs best with my memory set to the lowest possible amount of 750 lol.

Yep, but you could also send the BIOS to the author of the thread and have him rework timings and then flash to what he sends back to you. Might actually get near the shaders*corespeed in ghz*.34.

That knowledgeable guy in the thread identified how the video card will use a set of different memory latencies, by looking at your memory speed, and then looking up up a table to see which set of latencies to apply.

Apparently, the table is broken up by sections of memory speeds. So from like 13XX to 1500 it would use one memory latency setting, but then from 1501-XXXX if would use another set.

Therefore, if you changed your memory speed from 1500 to 1501, that would trigger a new set of latencies be used, as looked up from that table.

What you could do, is try keeping all your settings the same, then change the memory speed just a little, to trigger the use of a different latency. We know that changing the memory speed by 1 MHz will have almost no effect due to the speed difference, but if you see a big change in hashrate, you know that your card is now using a different memory latency table entry.

Apparently this guy is so skilled/knowledgeable, he can re-do the video bios by completely re-writing the entire table to fix every one of the latency entries, so it doesn't even matter what memory speed you use, because every entry in the table will be optimized, so it's no longer a crap shoot trying to find the "sweet spot" in the latency table.

Pretty much a huge breakthrough, that solves the "mystery" aspect of why hashrates seemed to be unpredictable. It's just because different vendors were sloppy or lazy at setting up the table of speeds that should be used, and XFX was notorious apparently for this. However, some guy seemed to have a huge bump after he got the fixed BIOS from that guy that corrected latency setting table.

This is my understanding after reading the thread earlier this morning, maybe things have changed since then. I'd really like to know more about how to go in and do the changes myself to fix/optimize the video memory latency settings that are used at various memory frequencies...

Dam Coinye Thread is surging at bitcoin talk. I just sold 200K of CoinYe for 1 LTC. This was with only 1.6 Mh/s for like 12 hours

 

[geokilla]

Is there a way to configure memory timings?

Crossing my fingers. I've uploaded it and sent him the link. The thread says hes working on 7970's and 280X's at the moment. Maybe He'll help me though.

Where did you do the exchange?

In the forum. Thinking I undersold myself but what the hell. Not bad for less than 12 hours of mining.

So what's with the value of BTC dropping?

 

[blastingcap]

So what's with the value of BTC dropping?

BTC dropping, LTC dropping even faster, difficulty is rising however. Next difficulty adjustment is in a few hours, estimated 13% increase in difficulty. Unless you have free power, that means your profits will drop more than 13% even if LTC prices remain stable instead of continuing to fall. No signs of difficulty slowing down, either, if anything difficulty increase looks like it's accelerating. http://bitcoinwisdom.com/litecoin/difficulty

Well I mine alt coins and then exchange them for LTC. I would never make a decent LTC if I were to mine it directly.

I still have 1.83 LTC stuck at Litebonk can't seem to have it paid out.

 

[blastingcap]

Altcoins are not necessarily better than mining LTC, especially with the low quality of pools and pool operators, exchange fees, risk of scams and being on the wrong side of a pump-and-dump scheme. Difficulty keeps shifting so that what is no.1 on coinwarz right now can be no.27 literally an hour later. Most problematic is how tiny the market caps of many altcoins are; it's extremely easy to manipulate prices on exchanges. Mining altcoins more resembles gambling than anything, you may get lucky or not.

 

[Silverforce11]

Bitcoin was premined. Litecoin too I think.

Acceptable in the early days as a reward for the work and development on the code, nowadays its so easy to use source code to make an alt coin its not justifiable to have premined. Especially so when its a coin designed purely for pump and dumping.

Buyers beware, just like Mooncoin this joke is in danger of crashing and staying down. Exchanges will start to remove "dead" coins and once its removed, its death is almost permanent.

Mining altcoins at Hashco.ws and Middlecoin.com have always yielded me more in BTC than mining directly LTC. They do all the work of exchanging and mining the best coins so you don't have to worry and chase it up yourself. Get your BTC and buy LTC with it if you love LTC. Win win.

By "always" you mean the last month which is cherrypicked data. Historically coinhopping pools have had long stretches where they weren't more profitable to mine than straight up LTC.

Anyone who mined dogecoin early on, including coinhopper pools, got abnormally high profits. In fact, those who mined dogecoin directly and held onto it benefited much more than coinhopper pools, which are forced to cash out every 24 hours, even at times when it doesn't make sense. But you can't count on a dogecoin popping up every month, that coin was very profitable to mine for a relatively long period of time with sufficient market depth and market cap to make it so that you wouldn't crash the entire dogecoin ecosystem by selling a few coins. The number of other coins like dogecoin? Zero. Dogecoin is unique.

Furthermore the more hashrate goes into arbitrageur pools like you mentioned, the faster the arbitrage happens and thus the less of a bonus you might get from such pools. So by all means, keep touting arbitrageur/coinhopping pools, the more you do so, the more hashrate goes there and the less benefit it is to mine there to the point where you might as well mine straight up LTC at 0% fee instead.

Yes, it's possible to get LESS money mining at coinhopper/arbitrage pools than mining straight LTC, especially if the arbitrageur pools have high % fees for exchanges and pools and higher stales and orphan shares. This has actually happened for long periods of time. In fact, it might be starting to happen now. If you look at the top 5 hashrates at middlecoin historically, it's clear that some big miners have left recently. Additionally people are finding evidence that the pool operator there is cheating and taking more than his stated ~4% fee; the biggest miner left on that pool says he's leaving soon if things don't turn around. Btw, Middlecoin has been spending more and more time mining--you guessed it--LTC. If you mine LTC, you have a good idea of what it'll be worth an hour from now. Low market cap altcoins which are vulnerable to market manipulation on exchanges can't say the same, which is why it's a gamble to mine most altcoins. Once again, dogecoin is an exception and is by far the biggest reason why mining non-LTC was more profitable last month. But dogecoin is an outlier and you can't count on a new dogecoin to emerge every month.

P.S. Even if coinhopping were a little more profitable to mine than litecoin all that does is delay the breakeven point by 3.5 days, since litecoin difficulty keeps going up so fast.

 

[taq8ojh]

I just read some posts on Bitcointalk and it doesn't really look like Bitcoin was premined at all. There were simply SO few people mining it in the first... year?

Nobody is forcing you to stay on when its not as profitable. Nothing prevents you switching back to LTC IF and when LTC is more profitable.

As it currently has been for over a month and even now, there are many altcoins that are more profitable. As long as it continues to be, then if miners want LTC, they get more by mining alts and trading for LTC.

Middlecoin last week had a running average of ~8000 Mh/s, its now: 11901, so yeah, looks like its dying. Not.

Nobody wants to edit their settings multiple times a day to get onto or out of a pool, let's be real here. And you keep cherrypicking data from recent times which include some highly unusual situations. Try looking at data for 1+ year time periods.

You also cited to stuff like coinwarz for profitability and were actually serious about it. Any veteran miner knows coinwarz is not reliable since so many of those listed coins have tiny market caps and very low difficulty, so there is extremely high volatility. Many coins have fast difficulty readjustments, and even if they don't, by the time you mine some coins they might be worth half of what coinwarz said. Low market caps are very vulnerable to price manipulation and are very sensitive to coins being bought or sold. With such low market cap, dumping more than a little bit onto exchanges will crash prices.

I didn't say middlecoin was dying; nice try to twist my words. You conveniently neglect to mention how its biggest competitor got hacked recently and most of those people moved over to middlecoin. So no duh, of course middlecoin's hashrate has been going up.

What I ACTUALLY said was that middlecoin's biggest customers have been leaving recently. There is an ongoing brouhaha ongoing about how its operator is cheating customers. The biggest miner still on the pool has publicly stated that his payouts are statistically abnormally low and that he's leaving soon if this continues. Smaller miners have such high variance that they can be cheated and not know it.

Coinhopping/arbitrage only works up to a point. Higher hashrate on coinhopper pools means faster arbitrage and thus every member of such a pool benefits less. Such pools are victims of their own success. (See above point about how coinhopper pools are unable to effectively "hop" on altcoins with low market cap since anything they mine can't be unloaded without crashing the price.)

All these things are extremely important and common. And they all happen(ed) to me.
People underestimate them and substitute real world with oversimplified equations.
N-days x price = PROFIT

Idd ppl will mine ANYTHING. But I have standards! And only mine crap-coin if its zero premine!

 

[Silverforce11]

I don't think you actually comprehend.

I don't care if the current situation is an abnormally, its been highly profitable for me and many others who mine alts and not LTC. As long as it stays this way we will continue to profit until the situation changes. If and when the situation change, miners can switch to whatever they wish, including LTC.

Simple concept really.

Oh please, Mr. "oh look CAT is on top of coinwarz that means it's most profitable." I'm still lol'ing about that one and how that was based on a glitch since CAT has just forked or whatever, and that you don't seem to understand that coinwarz is unreliable because it's instantaneous-measures so what's no. 1 now may be no. 30 an hour from now. Altcoins are perfect for such market manipulation with such low market caps and difficulties.

Nobody wants to keep having to change which pool to point to, keeping track of all the exchange rates, etc.

Sitting on a coinhopper pool isn't necessarily more profitable because they have to cash out every day even at times when it doesn't make sense and also charge hefty pool fees. Plus it's very hard to find good arbitrage opportunities, as I already explained in other posts. In fact, Middlecoin has been mining a lot of litecoin lately because litecoin is most profitable. Yet that pool is charging you 3.5+% for doing what other pools do for 0%. That's a bad deal. So what are you going to do, edit coinhopping pools in and out of your config all the time? Lol.

Anyway, bottom line: mining difficulty is going up, up, up, and the LTC/BTC ratio keeps falling, so mining profitability is going down, down, down no matter what you are mining.

In the short term yes. If bitcoin (and therefore altcoins) rise by another extraordinary amount and you are in longer term, these details (profitability/day) would be minor considerations. On the other hand it may be that the altcoins crash, and you lose the cost of electricity.

If you cash out daily or regularly then they apply. If not, they don't, at least not as directly - especially if you convert to a stable or growing coin.

Yep, it's certainly not entirely straightforward. Either follow and gamble carefully, or aim at the multipool type thing, or the coin you suspect will retain or gain value.
