Think I will take some time this weekend and read up.

Would be nice to make few bucks here and there on some hardware just collecting dust ....

Awesome.

I have neither the hardware nor the cooling.

winter time would be great for this though, get paid to run your heater :)

This could potentially pay for my folding activities which would satisfy me...more research is needed on my part.

Exactly, Im leaving most of my NVIDIA hardware to the F@H and any ATi equipment will be paying off the hardware and power bill :)

For those interested I posted up a Step by Step Guide on how to get started: http://bitclockers.com/forums/index.php?topic=3.0

wow vv! that's like my house with better hardware!!!
nice setup bro

Since I'm selling some cards due to money shortages.
Am left with a 4870X2, might aswell get it doing this (is there any point with just the one card?)
And would I need 1 or 2 miner clients since it's a dual gpu card?

I will be adding a few more 4U racks and filling every 4U with 4x 5870's or 4x 5970's
ThermalTake package came from ThermalClause:

Im going to need and electrician to wire up a damn sub panel for this bad boy




I say YES good sir!

Your 4870X2 is paid for and has no upfront cost for you to Mine with so here are the results after 1 month :D

Time Frame 1 Month @ 200Mhash/s @ $9.60 (USD) per (BTC) Bitcoin
Revenue per time frame: 135.87 USD
Revenue minus power costs: 127.10 USD
Net profit first time frame: 127.10 USD

lol thats 4870x2 might just pay for a tank of LN2 :D

not bad for old hardware laying around


For the 4870X2 you will need to install AMD's "APP SDK" package
"AMD Parallel Processing Software Developers Kit"

Just tried setting it up, getting around 50Mhash/s per core of the gpu, and getting quiet a few rejected, about 50/50 atm. Card is at stock, temps are <80 degrees.
Any ideas?

I have a 4870 that runs 90Mhash with a little OC and it uses some command switches or on GUIMiner "Extra Flags" to optimize the Mining client.

The 4870 is not on it yet but will be soon.
You could try playing with adding and removing flags and increasing and decreasing the value
Here are some flags:
-k
phatk
VECTORS
BFI_INT
AGGRESSION=10
worksize=256
FASTLOOP=off

Any idea whata 6850 would pull? I checked out hte calculator and I couldnt change the video card.

Interesting idea.. if it nets me $100 with a 4.3GHz 2600 sandyB... I would say it mets out i my favor. once the blocks drop to 25 (soon) that halves income. and income is purely based on on an arbitrary value that is being inflated by bitcoin users.

Having said that..

What the hell is it really? My PC is cranking out hash values to get coins.. umm. What are they actually computing?

Free money for CPU cycles and I have no clue what they are actually doing?
