Cryptocoin Mining?

[kly1222]

Tried both 11.7 and 11.8.

No more dummy plugs and crashes from hardware accelerated video, ccc, gpu-z, 3d apps, etc fixed.

But I'm getting 100% cpu usage on my first core with affinity checked on miner. Forced me to go back to 11.6

 

[Zargon]

hmph.

I would love to not have to pause my 6 series cards, but 100% on one core seems worse...

which miner you using?

 

[kly1222]

Latest python using guiminer.

I noticed some issues with afterburner 2.1 also on 11.7. OC and fan settings weren't always initializing right away on bootup. Had to manually apply it to get the settings to kick in.

I found a calculator that is suppose to predict your break even point which also adjusts for increased difficulty over time.

http://bitcoindetailedcalculator.appspot.com/

They way they seem to figure, in thirty days it will be pointless to bitmine. Is that realistic?

 

[WhoBeDaPlaya]

What's the consensus on 11.5 vs 11.6/7 for mining?
My standardized Win7 images all have 11.5 for ATi cards and I'd like to try my hand at it when I'm not gaming using my 6970.

that's one of the better calculators i've seen. far more useful because it gives a good daily breakdown. the default numbers are a little off, but mining is highly dependent on location/equipment. I had to tweak the wattage value down to match my actual electricity costs($30/month). the default diff change value is set to last 3 month avg.(1.3) while the last 2 diff values have been around 1.1.
if you can find out your electricity costs from your bill, or know the avg of your region, you should be able to get an accurate estimate.

based on my values(0 system costs + $300 in video cards) and a diff change of 1.1, i wouldnt break even in 3 months if i started now. it also tells me that at 2months my returns reach a point where it isnt worth mining. luckily SI should be out by then.

a full 3card 5830 rig at 900Mhash will never break even ever, if it starts now. unless your electricity is free or btc jump over $30/coin, any mining scenario requires you to sell your cards to make any profit. and SI will massively cut that margin the closer it comes to release.

Do you think SI is going to be better for mining? Or, are you saying the reduced value of the VLIW4/5 cards after the release of SI will kill profitability? Sorry, I'm just trying to better understand your message.

Using 11.7 now, seems like a nice upgrade. No more need to plug swap or use dummy plugs, no real drawback. Not seeing the high CPU usage. Does that only affect 6 series cards or something? I've never seen it occur for me, CPU usage around 5-9% on each miner.

What GPU you have ? and How many ?
What minner software you are using ? (flags ?)
What version of older driver you had ?
What OS ?

This is fixed in 11.7?!

That's great to hear, last I heard it wasn't going to be fixed until the 11.8 release. That's nice if it's included in 11.7, though, the bug was driving me nuts.

Where can you download the pre-release drivers (like 11.8) anyway?

edit: Stupid question, just noticed the link on the previous page.

yeah sorry, i had a feeling i wasnt going to be clear. (it is just a crap ton of variables that goes into this)

the upcoming SI cards can either:
A) perform worse in integer(hash) than hd 6 series [in which case cypress and cayman users get a reprieve and get to mine profitably for a few more month.]
B) perform equal to hd 6 series hash [but will likely be better performing electricity wise and might be more attractive as an upgrade]
C) perform better than 6 series hash. [making upgrading manditory]
But regardless of hash power, it will likely perform better in games than 6 series.

potential factors:
-amd refresh/reuse the vliw4 and the die shrink will up hashs just because they can stick more sp's in the die. [hashes +]
-amd goes gcn on 28 nm HP with some sort of vliw4 subcore [hashes +]
-amd goes gcn on 28 nm LP vliw4 and uses up die gains with redundancy traces [hashes =]
-amd goes gcn on 28 bulk and is generally neutral performing [hashes =]
-amd goes gcn and simd is disastrous for integer [hashes -]

any number of amd's options in designing SI can result in scenarios B or C but only an extreme worse case scenario will make A happen. But either case, more people will own cards with decent or optimal hash rates and it's guaranteed that some of them will mine.

Anything that increases number of miners or total compute power will increase difficulty which automatically kills profitability given the stagnant price of btc. As soon as difficulty increases go above 1.1 most miners will never hit a break even point unless you have really cheap electricity.

In that case you are required to sell your cards in order to eliminate your initial debt/investment and turn a profit on what you have mined. The less your cards are worth, the harder it is to turn a profit. And there are just too many things that will drive down the resale price. (new cards push down value of older cards, upgraders selling old cards to buy new cards flood the used markey, increased hash rate and lower power usage make old cards less attractive to miners, older cards unable to play newer games, etc.) While you might be able to find 1 chump on ebay willing to buy a 5830 at your original cost, can you find 7 chumps?

My critical point is that regardless of how SI performs in integer/hashes(and given the fermi example it is unlikely to be horrendous), the fact that it comes out will change the market which will affect everyone with a boatload of 5830's or even lesser performing 6 series cards to offload, and they need resale prices to be high in order to eliminate the red ink they accrued to build the miner rig. That's why there is a time factor or deadline to power mining.

As I have advised before, everyone who is power mining or considering it, needs to be running a spreadsheet with debts and actual power costs with a difficulty tracking value applied to btc return extrapolation. The calculator dougoman posted is a cheap shortcut if you cant figure out the maths.

 

[Zargon]

thats a really well put together post gorobei!

 

[Mir96TA]

I have Ati Radeon 5850 1 GB ver with P45 Chipset and running on Win7 Pro 64 bit.
11.7 and .8 made no differnce in mining but cpu usage jumped to 40 %
I down graded to 11.6
BTW I did had a issue visual redistribution c++ and it was unable to install it

Thats figuring a 30% difficulty increase with each increase, which at this point seems really steep. Unless we see a mining surge, i think 10-15% difficulty increase is a more accurate guesstimate.

This next increase will also be affected by people who switched from namecoins to bitcoins after the latest namecoin difficulty increase (you could get bitcoins at twice the rate by mining namecoins and trading them there for a bit) and i still don't think it will even be 15%.

 

[hawtdawg]

Forgive me for being lazy, but can anyone tell me if the latest catalyst drivers fixed the issue with video hardlocking your system with 6xxx cards if you forgot to pause the miner?

 

[frostedflakes]

Yeah it's fixed in 11.7.

Now if only they could fix the 100% CPU usage when mining with multiple GPUs. 11.8 pre-release didn't address this did it?

I think you are looking at it in an overly simplistic way. For example, some people pay half as much as me for electricity. Some people pay 3X as much, some people legitimately get free electricity (condos with electricity included). Efficiency of the graphics card is really just one small piece of the puzzle. If you live in a condo with non-metered electricity, it doesn't really matter if SI is more efficient. If I pay half of what you pay, even if SI is 40% more efficient it's still going to cost me less for electricity to mine on my 5830.

If SI is great at mining, I agree that it will trigger some difficulty increases. But I think 5 series cards will remain profitable to some degree for most people, while those who pay the highest for electricity might get edged out.

it doesnt matter how many miners have reduced electricity costs. the scenarios merely outline the range of SI probability and how each more or less drives upgrade or new purchase. If you run the calculator dougoman linked or make a spreadsheet, you will see diminishing returns due to difficulty increases(even at the mildest 1.1 - 1.15) still makes any older rig irrelevant in 4-6 months.

The numbers dont lie. You can argue about what is worth for some corner cases, but the majority of people wont make it to break even on $1000+ expenditures before the returns fall below a reasonable level. You need a massive upswing in btc value to make it worth mining.

Actually you would need SI to generate 700-900 mhash/s in order to sustain the kind of returns you are used to when difficulty hits the 3million range. We will probably cross the 2million line after 2 more rounds(3 at the most).

Run the calc, tell me when a 3 card system starting now crosses the break even point. Say a nominal 1 G/hash at $20 per month of electricity(tweak the wattage value and cost at .11$/kwhour) at 1.1 diff change over 12 months at a fixed $14 btc.

5 series is more than 2 years old now and still profitable. Where do you get your 4-6 months figure?

Difficulty increase effect everyone and everything equally. It's all one big equation. If you double efficiency but you also double cost of electricity, your output doesn't change. Currently, mining is profitable for people with electricity cost 3X as high as mine. That is functionally equivalent to me having a 3X as efficient card, yet they are still in business. SI is simply another factor affecting profit just like difficulty and electricity cost, there is nothing special or significant about it unless it really is a huge (4X or more performance for same electricity) efficiency upgrade, which I doubt.

Besides all that, SI will not be priced at the same level as 5 series cards are available now. Even if an SI equivalent can do same MHASH as a 5830 for half the electricity, I bet you anything it'll cost a lot more than the $109 deals we had a month ago- probably more like $175 or $200.

Too bad its at least $1 less per coin than it was a couple days ago :\

i'm being very generous with the electricity watts and cost here. this is for a new 3 card 5830 on a single m/b with a 800w psu and hd + os ~700$.

after 3 months you are down to half your btc rate, after six your are earning 1 coin in roughly a week.
