Cryptocoin Mining?

Re: Intensity Setting

Do you guys notice higher rejects at higher intensities?

I just noticed that my 7950 running at I=20 had about a 3% reject rate, whereas the 7950 running at I=18 had about a 0.2% reject rate. Same pool, same difficulty, only difference is, the one at I=20 is running at ~100kh/s higher than the one at I=18 due to different clocks.

The card itself is stable at those settings I think because it's not hardware errors. What could be causing that?

You can try lowering thread concurrency or intensity because if your thread concurrency is too high and you are trying to run a high intensity, you might get HW or higher R.

I usually don't pay much attention to anything other than my WU. WU is your effective hashrate which accounts for HW and R. I try to keep my WU close to my hashrate, if it is within 5-10% of my hashrate, then it means everything is running optimally.

Try lowering your overclock a bit. I run mine at intensity 19. Intensity 20 definitely results in higher reject.

K thanks. Both cards are at ~10% difference between hash rate and WU. I changed the intensity to 18 and the reject % seems to have gone down. Will keep a close eye on it.

Can the WU be more than 10% lower than the hash rate while having no HW errors and low reject rate?

I run my 7950 at 20 intensity and sadly enough, it is on par with my 7970, but I use my 7970 as a display which lowers hashrate by 20-30 when not under load, and up to 100 when under light load (watching videos). So far, I have less than 2% rejected shares on my 7950. What are the rest of your settings?

 

[KlokWyze]

So Ripple sounds scamish after reading this.

The entirety is premined with a portion being held by opencoin devs. Every article I see for it is either a hit-piece or is completely in love with it, which just sounds like big money trying to sell snake oil. Also, it's centralized and completely controlled by 1 company.

Unfortunate this is #2 in market capitalization. Can someone explain how this isn't a scam?

1140/1500 which at I=20 gives ~630kh/s, at I=18 it gives about 610kh/s
TC=24000

 

[holden j caufield]

what is the safest cryptocurrency exchange or the one that's been around the first/longest. Are btc-e mtgox bitstamp safe places to trade and leave your coins?

 

[Silverforce11]

I've no problems with btc-e and localbitcoins.com, not sure about others, someone else can chime in.

 

[Borealis7]

so BTC is rising steadily now around 860$ after being at 550$ not too long ago.
is anyone going back to mining BTC instead of yo'mama-coin?

 

[DooKey]

I use BTC-e and Coinbase. No problems with either, knock on wood.

 

[njdevilsfan87]

We are definitely entering mania phase (assuming we haven't already):

Could be the "return to normal peak" as well, with BTC now getting close to $900 again. I believe January 31st is a big day for BTC as that is when the "China ban" is official. I'm not sure what workarounds China has announced (I know they have) or whether or not they'll be effective, but if there's going to be a big crash coming this month again, it's going to be because of that date. Right now we're just too far away from it and riding way too much upward momentum.

Thanks for the info, whether or not it turns out to be relevant (31st).

 

[darckhart]

thanks for all the help, but obviously there was some conflict in my system somewhere because I just performed a fresh install of win 8 on a spare hdd, ran win updates, installed cat 13.12, downloaded cgminer 3.7.2, and used the EXACT same bat file, and everything works just dandy.

Since it was all connection problems, I'm going to go back to the other system check all the networking/firewall settings, etc and see if maybe that was the cause.

cgminer.exe --scrypt -o stratum+tcp://usa2.wemineltc.com:3334 -g 1 -I 13 -u darkhart.1 -p 123456

You need a fast ASIC miner to get anywhere with BTC. Even my 8Ghz miner barely produces more than $100/month, oh and it burnt out and needs RMA'd.

 

[Binky]

Oh great, doge forked. Mandatory update. Make sure your pool is on the right fork!

I agree with the above, though I think such a crash would come before or after that date. Before if Chinese people give up and don't want to be the ones holding the bag by that date. After, if Chinese people think they can circumvent the ban but then give up when they run into problems. I expect nothing to happen on Jan. 31 itself.

noob question, can you mine at all with NV?

 

[IEC]

noob question, can you mine at all with NV?

Yes (cudaminer), but at a significant penalty versus AMD due to the hardware being less suited for the scrypt algorithm.

Expect at best 1.6 kH/W (for 780) versus 2.5-2.8 kH/W for AMD. If your power is "free" or dirt cheap it might not matter too much, though you'll still be getting significantly less hash rate versus the AMD cards.

 

[Silverforce11]

If you are getting free electricity or pay near nothing ~5 cents/kWh, then 780, Titan and 780ti are very good mining cards, getting 600 (780) kH/s is a good start to generating some decent coins per day. Its been a good development with Cuda miner, NV really needs to reach out to that dev and give him support to push it further.

On other news, looks like whatever potentially negative thing the chinese government do, BTC no longer cares. Its nearing $1,000 USD per BTC mark and climbing fast.

Early 2013, I had my personal bet that BTC would go from $30 to ~$1,000 by Xmas..
Next Xmas, my bet is on ~$10,000 per BTC.

 

[thilanliyan]

Man I hope you're right!!

And here's to hoping it drags LTC along with it!

If you ask me, you can flip it around and say LTC is gonna go from $30 to $1,000 by Xmas :awe:

 

[blastingcap]

If that's true, you'd profit way, WAY more just by buying as many coins as possible and holding them for a year. Only if growth is sub-40% over the entire year would you gain more mining at 15 cents/kWh. Even if you pay only 10 cents/kWh, if prices double or more you are better off buying and holding coins directly.

 

[nwo]

If that's true, you'd get WAY more just by buying as many coins as possible. Only if growth is pretty slow, like 40% would you gain more mining, at 15 cents/kWh. Even if you pay only 10 cents/kWh, if prices double or more you are better off buying and holding coins directly.

Yep, I'm aware of that. And if the price tanks back down to $10 again, I'll invest at least a grand for sure. With the price now nearly at $30 and $40 being the highest price, I'm reluctant to buy into coins directly at this point. But I still have faith in the LTC I am mining and plan to hold onto them for at least a year, depending on prices.
