Other / CPU/GPU Bitcoin mining hardware / ATI Radeon 5870 almost dead, it can be fixed?!

Guys,
I have an ATI Radeon 5870, the video output works, I can use X Window under Linux normally... But when I start the miner, after one minute or so, the machine hangs up.
The temperature jumps from 60 to 127 right before the hangs...
My MOBO is a 790fxgd70, if I change to a 890fxs-gd70, I can still use the machine but, the miner does not work anymore.
I take the 5870 to a hardware assistant and he told me that a small chip-set of the board is gone, the one labeled:
√
VT1165MF
AG0927
1826551
Seems to be the Volterra VT1165MF voltage regulator... Right?!
Can someone fix that for me?!
Also, the FAN is dead too... lol
EDITED: But I have another FAN cooler and, I can buy one from eBay if it can be fixed.
Thanks!
Thiago

Aí sim hein!! Não ví a Icarus na página Bitcoin Hardware Comparison...
Seria legal se estas FPGAs forem compatíveis com o barramento PCI-e, bastaria trocar a 5870 pela FPGA.
Pois os meus mining rig, não são dedicados ao garimpo de bitcoins/litecoins, também dou uma série de outras funções para os computadores. E vou manter isso após mudar de videoboard para FPGA...
Não vejo a hora de a FPGA p/ Bitcoin mining se tornar um produto final.
Valeu!
Thiago

Só para comparar:
Vídeo = ATI 5870 = 440MHash = 210W = U$150.00
FPGA = Xilinx XC6VLX240T-1FFG1156 = 375MHash = 16W = U$1795.00
É muita grana por 375MHash.
Vou começar a pensar nos FPGAs em 2013. Pois é uma tecnologia muito beta e que precisa de muito desenvolvimento.
Até lá, vou terminar o meu mining rig de 25GHash e iniciar um pool, ou mesmo, entrar para o pool do futuro, o P2Pool!
Abx!
Thiago

Bitcoins, dúvido muito...
Mas, pode garimpar por Litecoins.
E depois vender os Litecoins por Bitcoins ou, usá-los de uma vez.
Dessa forma, renderá mais Bitcoins do que garimpando por eles diretamente.
Eu acredito tanto no Litecoin quanto no Bitcoin e, acredito também no Namecoin.
As demais *coins não me agradam.

I am glad to see that, but when you go here : http://bitcoinstats.org/count.htmldoesn't look it should be rising at all mining difficulty is rising, but not that much... do traders have some inside info or what ? only thing that I can use to explain this is that people are less afraid EURO will fail. Dollar will fail. Real will fail. Bitcoin will win! Litecoin will win! Namecoin will win!! People are realizing that!!! Best! Thiago |

Bitcoin / Bitcoin Discussion / Re: Increases in bitcoin prices are bad for merchants

I get the feeling that people spend less bitcoins when they see the price going up. This is an unfortunate side effect where all bitcoin holders become speculators and are just waiting for the market to tops off and buy things (or convert back to cash).
So the more it is going up in value, the less actual economic activity it is used in.
I am looking forward to it leveling back off again. The ups and downs are bad for bitcoin.
Welcome to a deflationary economy!!!  |

Alternate cryptocurrencies / Altcoin Discussion / Re: Request for an Scrypt capable fork of cgminer - maybe within new CGMiner / RPC
|

With Pooler's minerd being such a killer app for Intel CPUs, do you really think that CGMiner could compete without ALOT of optimizations ?
Why not Bounty-Request Pooler to add enhancements to his minerd for LTC mining ?
I like the CGMiner interface / RPC features and, the CGMiner with Scrypt support will (I guess) have the pooler's code. So, it will be basically the same. Anyway... We already have the negative response from ckolivas and Kano, so, never mind... I just being curious on why the two hate so much a new piece of code within CGMiner... I think it can not hurt cgminer, it can be a plus to it. |

Vamos generalizar, cantinho em que se fala Português  Quando o nível de dificuldade sobe torna-se mais difícil geral moedas. Cada vez é preciso mais MHashes para encontrar um bloco (até mesmo numa pool demora). Este ano vai ser um ano que as FPGA vão dominar, com os seus baixos gastos em electricidade e alta performance MHash/$. Quando você acredita que isso irá acontecer e, quanto custará 440MHash em FPGA até julho, por exemplo? |

For CGMiner 2.0.8~2.1.0 binary at Ubuntu 11.04, you'll need to modify a few things at your Linux to get it running.
Thiago, what did you do to get CGminer 2.0.8 or 2.1.0 to work in Ubuntu 11.04. I tried to search the cgminer thread but I don't seem to find what is the catch. CGMiner 2.06 works fine for me as well. Thanks, You must run as root: cd /lib/
ln -s libncurses.so.5 libtinfo.so.5
