Seems that we're having only one lone idiot here, and that's you. Do you see how many people are against you?

Who asked you anything? Speak when spoken to, fuckwit.

@davout I love it how they quote rettardit as the source of the method to avoid doublespends that Satoshi Dice pioneered.

You know, the MPEx Satoshi Dice.

MPOE-PR just likes irritating people. Common sense be damned.

If they didn't receive your money until after betting was closed, then you didn't purchase anything. Whatever is written in the rules can't take away your consumer rights. If they don't provide the service paid for or send a refund it's just theft. There not protecting anyone by keeping the money, just lining there pockets.

I  heard about a 38PH/s rig (MAMMOTH) coming out soon. Designers just have a few wrinkles to work out. Hint* it may be the Google mystery barge..

I would buy R9 280x simply because its new and has better resale value...

I doubt they are even making the 7970's anymore. The 280x's are cheaper as well.

Not if you buy used 7970.....

There almost identical cards and should should get the same speeds. There's no reason to go such great lengths to get a 7970. 

Used 7970 is cheaper....

Not much of a comparison. GPU's don't have a long lifespan mining. Hopefully you at least get one that a miner didn't owned. So far I've had a 85% failure rate on my cards after 2 years of mining.

Sold my 2 290x cards, just didn't have time to mess with them right now trying to find better settings. I was expecting someone to have found settings for 1+MH/s when I got back to check the thread, thankfully my 920/1500 is still the best.  Tongue

The 290x is not going to be a good card for mining. At least at these prices.
206  Alternate cryptocurrencies / Altcoin Discussion / Re: AMD R9 290X? on: November 15, 2013, 03:11:08 PM
I put a Kill-a-watt on my rig today. I'm running one 290x and one normal 290. Together there running around 650 watts.

what are your hash rates at that power draw?

1680Kh

They run really hot as well, doubt they would be stable at room temp even with good fans.

Nice, did you undervolt and overclock?

I didn't change the voltage. 920/1500 on the 290x, 947/1250 on the 290.

Is anyone getting above 880/Kh with the 290x. Mine seems to go slower if I try to increase above 920/1500.
212  Alternate cryptocurrencies / Mining (Altcoins) / Re: R9 280X or HD 7970 on: November 14, 2013, 12:56:29 AM
I have a Gigabyte 280x and the max I can get is 640/Kh.

With --shaders 2048 --thread-concurrency 8192 -g 2 -w 256 -I 13
1100 clock
1500 memory
I only get 596/Kh



Try lowering your overclock and changing your thread concurrency.. 640/Kh is not optimum yet...

I only reached 640/Kh with

--thread-concurrency 16384 -I 20

It is computer data and as such, should not be considered currency and/or a means to build wealth/prosperity.

It is being used to fool us into going cashless.

What will you do if they turn your power and/or chip off ?

 

What happens to your dollars when we run out of trees? Seems about as likely.

This thread sounds fishy as hell to me. Didn't have time to set it up. Sounds like a sympathy story, followed by a scam sales pitch.

Has anyone created a list of the coin and bullion vendors? If not I will start one here, if you guys post some.
219  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales now open ***full prototype pics*** on: November 02, 2013, 12:12:12 PM
Guys, we made good progress today, shipping all of the product we had available.  Tomorrow I expect to receive a mountain of stuff that was shipped through the week.  I'm not sure why it piled up to the end of the week, but we are all planning to work.  The shipping crew just left after prepping boxes for tomorrow morning's ship out.
They will then use the rest of Saturday, and all of Sunday to prep orders for Monday shipping.  I think we may have everything out by Tuesday or Wednesday.

A few things to note about these rigs:

-out of the box, a full rig will do between 550 - 600GH/s.  These boards are factory volted to .865v
-if you don't put solid airflow on them with fans, the cards will cycle - the regulators will get too hot, shut down, cool off, restart, etc.
-use the three case fan connections for sure.  A box fan will also help!

I'm measuring 600w to the power supply with a rig running at this rate.  PLEASE use two seperate PCIe power cables to power your rig.  Check cables for warmth - lets be safe folks!  Be careful trying to plug too many rigs into a single power circuit - 15 amps on a 15 amp breaker is NOT ok Tongue

The cards are very strong and so far very consistent.  There are still some EOL's and a few noisy cards too.

I really hope you are all really happy with these hot rigs!

Cheers,
Dave

Some power supplies have a heavier gauge wire for the pci-e cables. OCZ uses a heavy gauge. Silverstone, Evga and Enermax don't, at least on my power supplies. Given a choice I would go with a heavier gauge for doing something like this.
