Hi ollierexx,

Already had an account on betercoin.org ... do I still get the 0% fees !?!?!?!?

Ok I've done some digging and it looks as so for some reason the graphics driver is disabling CUDA support (and OpenCL support as well) hence why applications (including cudaminer and cgminer) can't see or use CUDA/OpenCL.

I am unsure why this is happening ..... I think it could have something to do with my motherboard (Asus P8Z77-V) and the integrated graphics card - although it is disabled the Nvidia driver may be detecting it and disabling CUDA support.

Has anyone seen this before?

CryptoLego: I don't get it ... you have basically the same set up as me yet I get the dreaded "Unable to query CUDA driver" ... what have you installed that I have not?? 

Any suggestions would be great!

I'm getting the following error:
"Unable to query CUDA driver version! Is an nVidia driver installed?"

Setup:

Cudaminer 2013-11-20
Windows 7 (64-bit)
nVidia GeForce GTX580 (running Geforce 331.83 drivers)

Does anyone have any idea how to get this working?

I've got the same problem:

You can pre-order quantities of 1 from their US reseller minersource.net.

Thanks Frank it's helps a little ... I guess the calculators do not take into account future exchange rates between btc and $$ which would be hard to do even if it's a guestimate.

I guess the real question is - if you had the spare money would you invest in 3 x Prospero X-1 and expect to get your money back + profit?

Hi all,

As you can see I'm new here

I've been having a look around for mining hardware and came across the Black Arrow Prospero X-1 bitcoin miner. I was thinking about getting 3 of them for a total hash rate for 300Gh/s

However I am unsure about the rapid change in mining difficulty ..... When I used the mining calculator at thegenesisblock it basically tells me that by the time the miners are available (end of Feb'14) there will not be enough time to make back my initial investment before the difficulty level gets too high.

Am I reading to much into this? Surely this can't be right? What's the point in making hardware for people when they wont be able to make back at least their initial investment? Am I missing something? 

Can anyone shed any light on this for me please?

Cheers....
