Bit mining hardware

Hi all,

Just started researching/dabbling in bit mining.  While I may be a tad late just thought I would try it out with some old hardware I have kicking around:
- HP desktop i3 with Windows 7
- I have three Dell Silicon Image Orion Pci-express Pci-e X16 video cards I could add in to the machine

Anyone have any thoughts on this hardware?  

If it works well, I may consider investing in an ASIC machine.

Normally you need multiple machines for bit coin mining and the electricity costs are high.

The machine above may do, but it will take a very long time (months perhaps) to get a fraction of 1 bitcoin.

Thanks and the electricity costs are understood but wanted to focus more on the hardware and installing multiple GPUs in this manner for use.

I've never had more than a single PCI-e video card in a machine some say it works but just getting fellow EE members' input :)

I did some reading before and I am not sure multiple GPU's would help the CPU cycles needed.

hmm, never heard of Dell Silicon Image Orion.. and the links in the net look like you cannot use them. You need a modern GPU supporting CUDA/OpenCL for any crypto coin mining.

These cards are old (average price on Amazon is $2USD) and simply don't have the gpu processing power you need. A single Nvidia 1070 would outperform it  Then you have to look at your cpu and motherboard do you have enough PCI-E Lanes available? Most motherboards only have 1 x 16 slot, very few have 3 x 16 slots.

Does any mining software can even use it? I doubt that at all...

Depends what coins you want to mine, some mining pools won't accept CPU/GPU mining for bitcoin as the network traffic is too high for the tiny amount of hash a GPU provides. Some of the altcoins are not mineable with ASICs and there fast GPUs are recommended; but don't use that much PCIe bandwidth or CPU power, single lane PCIe is fine, you can buy PCIe x16 to x1 riser cards to connect the x16 cards to the motherboard.

Good luck on getting an ASIC miner, if you buy direct from the manufacturer you can sell it on eBay for 50% profit when it arrives.

Bitcoin just crashed about 50 percent in 6 hours. Still at least the government can't crash it by issuing yet more banknotes (qualitative easing)

Fiat currencies are a gamble, Zimbabwe pounds just dropped 3% against USD. My UK pounds are worth less than they were worth a year ago and my Euros go up and down with the weather.

All great input and I’ve chosen to shelve this.  Apologies for the very delayed reply. :)
