my gpu is r9 270.


Having trouble getting sgminer to work.. it just pauses at start screen

ok i'll do that but i can't get the sgminer to work

can someone tell me how to setup sgminer?  
can you use cgminer for this? What's better, gpu or cpu mining?

this is my .bat file but it doesnt start up

sgminer.exe --kernel darkcoin -o stratum+tcp://drk.coinmine.pl:6090 -u x -p x

got nothin for 12+ hrs. it was still mining on localminers.com when i woke up this morning, just that I'm not getting any payments. Network / global hashrate still shows as normal

i didn't get paid for the last 10 blocks or so, what's the deal? Checked last blocks found and my wallet address isn't listed. My stats aren't listed on "such graphs" either.

Now I'm short 10-15k doge.

Everything was working fine for a week till yesterday.

it has 4 rails, I think i saw some people running 6 cards on these, or am i mistaken? If 6 is possible, do you connect the other 2 via molex?
I will be powering 6x r9 470.  Each card only uses about 150w, problem is, each card requires 2x 6pin.. Having trouble finding a <1300 watt psu that has enough cables / rails to run 5-6 cards.  (I don't want to go through trouble of rigging 2 PSU)

PS whoever snatched up the 1600w while i was debating, i hate you!

i have 6 of these Gigabyte R9 270.  They require 2x 6P PCI-E for power
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125491

I was hoping to run them off two 650w that I currently have... until I realized that I don't have enough cables. Furthermore I don't think these PSU were meant to run more than 1 or 2 cards because there aren't enough slots on the back..  GG.

So I guess I will have to order this 1200w LEPA PSU and hope that it has the right cables:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817494011

I can't tell from the picture, but does it have enough cables to power at least 5 of my Gigabyte R9 270s? It says there are 8x 6+2P, It looks like there are only 3 slots to power 3 GPUs, how do I connect the rest?

Do you guys think I should return the Gigabyte's and get these ASUS R9 270 instead? (they only require 1x 6P for power). Or is there no need with this 1200w PSU?

If possible I would like to avoid the trouble of returning my GPUs and waiting another week.

I guess this is my dilemma, i cant find any single PSU that will support 5-6 cards, this seems like it would be a common issue?

what is the stoneD.exe for?

and where is the philosopherstone.conf file?

"Log on once a week and your Stones will do the work creating more - no mining hardware needed, even your old laptop is more than enough"

what do i log on to? i'm so confused 

yea that 1200 LEPA will be my first choice if i just decide to go with a 5 card build. It's also in stock, for now :\

yea it's crazy, i was checking the quantities and it seems like all the 270s are selling out as we speak. I wonder when new stock will come in and if prices on the 270 will be the same

sometime after the new year I believe.

why is 2 6-pin connectors bad, as opposed to one? (nevermind i think you already answered this before i was able to reply)

Just some math comparing the two cards. And since you say that the 270 uses less than 200 watts then that gives it an even greater advantage over the 280x

2,250 kh/s - 5 x R9 270 = $900  

2,250 kh/s - 3 x R9 280x = $1260

I actually have spare motherboard / cpu / HD / ram / 650w PSU's I could use so I don't need to spend money on any of that stuff.. Only thing is the 650w psu are rosewill brand so I don't know how that will hold up.

I respect both of your advice, and the only way to know for sure is to test it out myself (ordered a kill a watt meter for this purpose), cus i think cards vary in power draw between brands.

I may just get the EVGA 1200w though, it's only $50 more and i may want to upgrade the cards in the future if i come by some cheap. I definitely understand the importance of the PSU, i've built a few rigs in the past.

In my research I feel it's safer to just use powered risers, only a few bucks more and at no disadvantage.

You're right about it having 2 dual 6-pin connector, could you explain why that is a bad thing?

btw, holy crap the gigabyte 270 already out of stock, there were still 70 yesterday at newegg.

thanks man i really appreciate it. I am quite technically skilled, and stress is expected.

I actually have bookmarked a lot of these troubleshooting issues while i was researching and came across them by accident.
I guess the 6 card thing will be an issue, is it just certain motherboards?

As for the PSU, that's too bad because I think one psu is cheaper and produces less heat? i was really hoping to just find a 1600w, because I want my rig to look clean.
Speaking of which, thanks for the link to the preconstructed frames, will definitely order from them. Good to know someone offers such a product for someone who can not hammer a nail straight if his life depended on it, at the price that it would have cost me to make one myself.

oh yea, will i need the extra long risers? or just the short ones for these specific frames?

Regarding the 280x, is it really worth it even though its more than twice the price?  $420 vs $180?

So, i've been keeping tabs on bitcoins for 2 years now, missed that train and finally decided that I want to get into altcoin mining.

I was following this guide http://www.coinminingrigs.com/how-to-build-a-6-gpu-mining-rig/#comment-36695
but am looking for second opinions.

Since the 280x and 290x are way overpriced now. I went ahead and already ordered, and am awaiting delivery of six, gigabyte R9 270 ($180). I figured I might as well bite the bullet cus they are selling out as we speak, i could always return it if I test one and it doesn't work out.

So I have just three questions:

1) Is this really the best card available now initial price to hashrate wise? or would you have gotten the slightly more energy efficient 280x at $420?

two, R9 270 producing 900 kh/s drawing 400w vs a single R9 280 producing 750 kh/s drawing 300w. Maybe I should have gotten the 280x.  Havent even received the units and i'm already feeling buyer's remorse haha.
The reason I didn't automatically go with the 280x is because all the 1600w PSU's are out of stock.
I guess #1 isn't really a question and I'm just looking for someone to reaffirm my purchase. lol.

2) Can someone recommend a place to get powered risers that wont blow up in my face? Was thinking about ordering from here:

3) Is this 1300w PSU a good choice? http://www.bhphotovideo.com/bnh/controller/home?O=&sku=1012719&Q=&is=REG&A=details
or should I wait for the 1600w LEPA to be available again, in case I want to upgrade the cards in the future (anyone know when?).
 I'm not in a hurry since I have other computers I could temporarily set these cards in.

so, what else do i have to change? it's running stock.

sweet, 280 mhash now. xD yea adding the flag worked. thanks!

btw, removing the flag doesn't do anything after adding it, how does this work? Do I have to press enter everytime i type something in the gui?


is radeon 5830/5850 still the best bang for the buck?  

Hey guys, I'm totally new to this.

I'm wanted to try this for fun and installed GUI miner. However, I found that my radeon 5850 only produces 150 mhash/s or less. Any idea how to fix this?
Any useful guides for a first-timer?
