I was due for a PC upgrade at home and I always wanted to try to mine. My current PC must be 5+
years old now. When I learned about bitcoin and desired to try it out CPU mining was on its way out.
So there was really no way to get involved with mining except to play around with the software and
read. Due to working at an ISP i can get free electricity while I am mining. I am allowed to have a personal
box on the network.
So I decided to buy a new setup. I wanted to keep costs somewhat sane at first to mine and then once
I decided I was all done with mining switch things out to make it a gaming rig down the road. So some parts
are a higher quality/performance compared to others.
The parts I choose were:
MSI 890FXA-GD70 motherboard - $195
(seems nice. plenty of slots)
Rosewill BRONZE Series RBR1000-M 1000W Continuous@40°C, 80Plus Bronze Certified power supply - $130
(I have always had good luck with Rosewill power supplies at home and work.)
2 x MSI R6950-2PM2D2GD5 Radeon HD 6950 2GB - $280 each
(I wanted reference models and I am pretty darn sure these are. Plus the extra ram will help down the road
with gaming I imagine.)
2 x Kingston 1GB 240-Pin DDR3 SDRAM DDR3 1066 - $13 each
(just cheapo ram to get me going. I did not want to spend much on this right now. It will move to a different
machine down the road when done with mining.)
AMD Sempron 140 Sargas 2.7GHz Socket AM3 45W - $38
(ditto with the processor. Just enough to get me going plus it appears it has another core which can be unlocked.)
Kingston SSDNow V Series SNV125-S2/30GB 2.5" 30GB SATA II Internal Solid State Drive (SSD) - $76
(I always wanted to try a SSD and it had a 25 dollar rebate. I did not really have to buy this.)
There is also 75 dollars in rebates I have to mail out to get back.
Total is $1025 - $75 = $950 without shipping/handling.
I am quite used to running linux/freebsd at work so I am not worried about those OS but I
also have a windows 7 64 bit professional license I can use. It is meant for this box and gaming. I have
a feeling tweaking is easier due to the tools in windows.
I estimate I will get 800M/hash per second with this setup once I tweak things. It also has the ability to
add another card right away and if I wanted I could add two more cards with another PSU/extenders
thrown in. So the price per M/hash will look better if I keep adding onto it I suppose.
Sure, I did find options to get more bang for my buck right now with other ATI cards but I really did not
want my gaming rig to have 5xxx series cards over the next however many years. I could have also shaved
off a few bucks here and there buying lesser parts or brands I am not used to.
I do not think I will solo mine with this setup. I guess I am chicken ;-) I have not decided on which pool yet.
If I have forgotten anything I will post additional information but this seems the way to go for a gamer/miner
type of setup.
Any thoughts or criticisms are welcome. It was maddening trying to figure out all the options using my spread sheet. Thanks for reading.
