I heard paypal  often charge back usd  when scammers  take coins with no intention of paying -- any alternative?

I have two rigs   one has 850 psu the other 1200 psu . and was wondering if any solar power units can power these

 my rig has a 290 card and a Platinum 850W+ ATX12V / EPS12V 80 PLUS PLATINUM Certified psu-- I would like to add one more card any suggestions for the most khs

I have a r9 290 card what other card can I add safely

 I have a 650 psu and will be getting two  r9 290 's will this work?

I've got a ASRock 990FX EXTREME3 AMD Quad CrossFireX nVidia Quad SLI SATA3 USB3 Motherboard--and only one slot is reading my 7950 will I  need to replace or can this be fixed?

If you could only use one card and had a PSU of 650 what video card you choose for the highest KHS

I've got a one year old  7950 that has been used for mining  / overclocked for a year. It doesn't seem to work is it trash or can these cards be refurbished and if yes how? I heard someone talking about flashing the card.

my rig has 3x 7950---  an asrock 990fx extreme4 --      amd sempron     



I'm having problems with it posting, the rig runs all fans and the system seem to turn on but I get no display, the mother board show a 19 in the digital readout.

any ideas for a fix

I'm looking for the best user friendly pool to mind alt coins with my usb block erupters, any suggestions

will not post shows error 19

the rig is humming-- fans are going but I get no display on the monitors-- all connections are place right

I had been mining ppc but the difficulty is going way up what should I mine next?

Once the scrypt asics come along  which coins  will all the gpu miners point to

Am I correct to say this is the latest asic technology?  any word of a newer more advanced  asic coming down the road and if yes when?

I'm thinking of buying a rig to mine ltc, however seems more profitable to just spend the 2 grand on coins

when will the  litecoin asics start shipping?

thinking of buying the Neptune with 3 th will the difficulty rise so much by april delivery to make it unprofitable   should I just hold my btc? unit costs $10,000 usd

thinking of buying the neptune from knc 3th-- good or bad move?

Good morning---  I am willing to pay a bounty to someone who can rehabilitate the geistgeld coin. Once place on an exchange I can pay 10000 coins, perhaps someone else in the community  would be willing to  add to the bounty.
