The point is that you did it wrong ;).

Leasing a mining rig can be really profitable, just you need to know what to mine.

When leasing a rig you should look for new coins on site like www.altcoincalender.info.

Then make sure you start it at launch with a lot hash while the hash is low and the coin reward high.

Also when launching a own coin some use it to rent some rigs at start for a smoother hashrate seperation.

And get there own coin.

Long shot, but could you have generated an address whilst running in administrator mode?

Good work!

There are differences to how the Hash rate is calculated. Because of its probabilistic nature an average is used. For the Feathercoin web site it is sampled over about 30 blocks, the hash rate can appear higher for short periods.

The hash rate can appear high due to strip mining where large hash rates are employed for short periods. Despite the fact that this is only marginally more effective than a lower hash rate spread permanently, they obviously don’t care what effect that has on the stability of a coins hash rate.

one error comes up that is no suitable long-poll found for http://127.0.0.1:9337

That’s normal… i get that too.

It’s because you are mining against the wallet and not a pool. As you already realized you can see if you’re mining if the cgminer sees the network blocks changing.

Good luck!

All completed. Good luck & look forward to seeing the finished article.

I’ve tried to make 290s work with 7970s and came to the conclusion that while perhaps not impossible, it is a royal PITA. Running 2 instances of cgminer with different thread settings simply crashes the driver. Within the same instance you can’t run different threading and the different cards like different settings to get decent hashrates. Before this, I was also unsuccessful getting a 6950 to hash alongside 7970s by the way. Couldn’t get even one of them to hash in a single instance. Homogenous rigs really are by far the most efficient, it seems.

How much memory you need depends on the thread concurrencies. At 8192 my 7970s are happy with 2GB RAM, but the much higher optimal concurrencies for the 290 bumps that number to 8GB.

Interesting thanks for sharing.

I think in time i will get another mobo and start a R9 290 rig. With the 4 5970s i was getting a little over 3 Mh/s, so with the 290 i would expect 3.8 -3.9 Mh/s. As below i am getting about 3.3, but i am down around 375 from the one disabled 5970 core. So i don’t think i am that far off the mark really. Over clocking the R9 seems to make little difference. And i am not to keen on trying the unlock to 290x bios hack as its a new card, and not sure its worth the risk/hassle for 100 Kh/s.

Haha, it is a good site. I just keep it open during the working day.

What about just moving the Fethers to BTC then move the BTC to Coinbase for USD. Lot cheaper.

Sorry its actually 3.1.1 I’m using with the summary rows. Not 3.3

I find spray a little harder to work with but it should do the trick. I like liquid and a syringe or pipette for a more precise application.

Can can backup the wallet.dat file and import it on the mac but it is easier and simpler just to create a new wallet on the Mac and send the coins to that address.

Cheers Chris,

I have a copy of wallet.dat from the windows box. But have no idea where to dump it on the Mac.

I’ll go with your suggestion of sending the coins, thats a great idea.

Cheers :D

Goes in the Home>Library>Application Support>Feathercoin

I cant find it in the application support folder. I have moved the program to applications, but cant seem to find the .dat anywhere. Any idea’s?

Oh on the new version of OS X you have to go to Finder Cmd+Shift+G then paste in “~/Library” without the quotes.

Because as standard it is hidden.

Great all sorted. Many Thanks

5970 will do 700 MHz??? Wish I knew this 2 weeks ago before spending £100 more on a 7970 *cries*

They do but don’t forget that they are older cards, dual GPU (so more power) and no warranty.

Swings and roundabouts really.

7970 ftw!

Asetek produces nice closed loop water cooling solutions. They sell many of them to Corsair, Thermaltake and Arctic Cooling. Accelero Hybrid 7970 is a good thing to have.

Thanks, I will try that key sequence later. I have managed to get a consistent 1.55M/h, one card is running at about 84C and the other 76C. I will tweek the fan speeds so that they are not 100%. Over night I had no hardware errors around 4000 accepts and 2 rejects. That sounds pretty good to me.

Thanks for your help. When I get home I will send you some FTC!

Cheers

Hi Rob,

Welcome aboard. Not to worry, we have a great bunch of folks here who can help you get up & running with a minimum of fuss.
