any thoughts appreciated, thanks

sounds like scam... 

i heard some gpu's work better with certain cpu's  would that be the case?

whats better processor mfgr to use?

how critical is cpu? what difference would having best processor make?

thx

the gpu cards plug into one end of the riser. then other end of riser goes into mobo. then the extra power supply cables connect to the end of the riser attached to the video card? this way the power goes from psu to gpu instead of threw board?

is this the board?

so there are 4 gpu slots, but double cards so only 2 can be used?

and riser cards move gpu the gpu? are they rigid boards? or cables? not sure how people can mount gpu's outside of case away from board...so 4 riser cards and you could run 4 gpu's using the 4 slots on the board?

this is cool:  https://bitcointalk.org/index.php?topic=7216.860

sounds cool. nice processor! i used gigabyte board as well. just 3.4ghz cpu. i liked intel chips better though... (not sure why other than it's intel)

both gpu's on one board? havent done 2 gpu's yet. thinking i remember you need dual gpu board to fit two gpu's?  makes me wonder how you hook up 5 gpu's?

was reading some articles i found looking at these: https://www.google.com/search?hl=en&q=extreme+bitcoin+mining&bav=on.2,or.r_qf.&bvm=bv.45175338,d.dmQ&biw=1440&bih=682&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&tab=wi&ei=9pJpUdqiJaLB0gGawYD4Aw

saw this one (i think i have almost the same case)  http://2.bp.blogspot.com/-IEWl9KCMnQ0/TgJTJVdstRI/AAAAAAAAAXc/cGOR1nTYegs/s1600/bitcoin-mining-rig1.jpg

some of these are way cool. and lot of $

also, had question, tried sending message to admin of this board , says admin blocked message. needed to correct typo in user name.. how/who do i contact?

not trolling trying to learn about bitcoin tech... please whitelistme if possible. ty!

nice to know, win7 it is... saw this article: https://bitcointalk.org/index.php?topic=136392.300   seems like butterfly labs asic is a scam
any pics of your setup?

thanks, for a noob you have good info thanks!

guiminer it is...

what os you recommend? win7?

1 BTC =111.32 USD   so 111.32 for 1 bitcoin. not bad, but thats 1/2 value as when it was $232.00   

what do you see on the pc when you figure out the hash and get bitcoins?

how do you know which site to use? any tips on choosing a site?
are all the programs (miners) the same?
the miner programs come from the sites themselves? not sure how this works...

$266 before crash, whats it now? and where can i look to see current pricing for 1 bitcoin to us dollars?

so, like 5k on cards, say another 5k on setup 5 rigs (2 cards each) so 10k investment pays 1 bitcoin per week? and $120.00 per bitcoin(?) means $120. x 52 weeks=$6240 minus electricity? means like i make 5k from like 10k investment (+ electricity?) or im missing something?

thanks for the answers... much appreciated!

"Once the asic miners start to come out mining on a gpu will get a lot harder."


you mean because more/faster asic will solve hash aster than gpu so by time im halfway finished they already done because their asic faster than my gpu?

First thing is ATM/AMD GPU's will work far better than NVidia.  ok, AMD it is...

Next with the current difficulty, you're looking at about 3-5 high end pc's to start making a somewhat decent profit. whats decent profit? i need 5 computers? how man cards each pc? 1-5? so maybe 25 cards needed?

I'm running 4 7970's (soon to be 5), 2 5830's, and a measly 7770. All together I get about 3.4 GH/s which is like 0.22 BTC a day.  whats numbers mean?3.4 GH/s? ghz per scond? of cpu? or total power? im confued....   and o.22 BTC a day, so 5 days=1 BTC?

The PSU for these rigs 1250+, you will be drawing a bit of power with cards, fans, etc. i bet...

Fans ARE A MUST! My cards run (auto target set) of 75 degrees celsius (167 degrees F) imagine 4 of them blasting in 1 room, it will make the room unbearable unless you have some type of ventilation setup, so you needs fans in the PC to help cool the cards a bit, or send cool air through the system.

need server room ac for all this stuff... thinking my electric bill will go thru roof..Thanks.

been lookin for a few days. gets confusing.


Early Bitcoin client versions allowed users to use their CPUs to mine. The advent of GPU mining made CPU mining financially unwise. The option was therefore removed from the Bitcoin client.

GPU Mining is drastically faster and more efficient than CPU mining. See the main article: Why a GPU mines faster than a CPU. A variety of popular mining rigs have been documented.


FPGA mining is a very efficient and fast way to mine, comparable to GPU mining and drastically outperforming CPU mining. FPGAs typically consume very small amounts of power with relatively high hash ratings, making them more viable and efficient than GPU mining. See Mining Hardware Comparison for FPGA hardware specifications and statistics.


ASIC Mining: An application-specific integrated circuit, or ASIC, is a microchip designed and manufactured for a very specific purpose. ASICs designed for Bitcoin mining were first released in 2013 and (at the time of this writing) are in the hands of a very limited number of miners. For the amount of power they consume, they are expected to be vastly faster than all previous technologies and will likely make GPU mining financially unwise.


1.) so i should be looking at asic setups? or fpga? have no hardware really, except 2 yr old x64 wndows box, 3.4ghz cpu, no "good"  gpu yet...

2. whats difference between bitcoin and litecoin? post i saw says nothing... maybe im just not understanding.. thanks

where to start? thats the question.. reading i see cpu replaced by gpu. now its aisc... how do i know where to start? any help appreciated thanks
