assuming that it would go through with mipspro at all ... thinking of bitcoind which is serious bloatware with some silly flaws in the build system

Yes, assuming it is possible. One can only try their best when fighting with GCCisms in code.

Gave it a run on my other Octane board (the other system wasn't booting, so I swapped the motherboards) (system is 2x 175MHz R10K, 1.5GB RAM). Result is 2x.08KH/s. I wish I still had the 2x 300MHz Octane that I was using in college in the LUG....I wonder if that is still there....

Lol, I can't believe so many people got into this! I built it back in Dec and left it running on my O2 600Mhz-- 0.21Kh, btw.

Sorry to disappoint you Geoman, a Fuel/900 gives about 0.4, though as I type this it's wavering
between 0.33 and 0.36 because of Firefox 3.0.19 and other stuff running at the same time.

Hmm, I might shut FF down, see what it does...

And what about putting one of those USB-based asicminers into Fuel's USB port for bitcoin mining?
The have got an Uart chip (internally they connect via serial port) on them and run inter Linux, too...

But in the end this all makes no sense at all :-)

Raspberry pi draws much less energy than a Fuel and don't make a sound.

Bitcoin mining is a complete and utter waste of time for a home user. It ceased being financially viable many months ago,
as the power costs now far exceed the mining returns, all as a result of ASIC/FPGA systems, etc. Rising energy prices
have made it worse, as have rising component prices for PC builds.

Litecoin uses a different algorithm for which there aren't any ASIC solutions as yet, so it's still viable atm, which has
resulted in a sharp increase in prices for AMD GPUs such as the 280X/290X/etc. What launched as good price/performance
alternatives to the 780/780Ti, especially with aftermarket coolers, are now far too expensive, and also top-end PSUs have
either gone way up in price, or they're impossible to find.

As for running minerd on a Fuel, I have my Fuel turned on a lot of the time, so it may as well be doing something useful,
good for a laugh.

Here too: My PC is running all the time, so the Radeon HD 7750 is doing around 100 khash/s (around 150 possible, but then the GUI gets sluggish), and I got myself an Antminer-U2 USB-Stick, which is doing around 1.6 Gh/s.

Of course this is more fun than anything else. I had the 7750 installed 1 year ago or so - so for Litecoin-mining I have no extra expense (and for electricity: my PC is nearly alwas on with or without mining), for the Antminer I paid 40 EUR just for the sake of participating. Draws around 2-5 Watts from USB. (of course directly buying BTC would be the sensible thing to do)

But who knows: If cryptocurrencies become really established in the future, we are now pioneers

and in 10 - 20 years we can say "I was part of the beginning".

Curiosity was burning a mental hole, so I tried out my 5GHz 2700K, which gives an average of 67.28 khash/s for CPU-mining.

After reading the 55 year old IBM bitcoin story http://forums.nekochan.net/viewtopic.php?f=8&t=16729659 I wonder if anyone is still doing this?

I might take some gear to work and hide them in the room 'no one enters'

Indeed! Hmm, I have other systems I could try, 4.8GHz i7 3930K, 3970X, etc. Also have a Phenom II 1090T but it's not oc'd yet.

I suppose results would be better with Linux, but I don't have any Linux setups atm.

Hey, I thought mining had moved away from Bitcoin anyway? Because the whole influx of ASICs and accelerators made it
uneconomic for desktop/GPUs. I read that Litecoin was a more productive option now as there was still no ASIC-based
method available, so CPUs/GPUs were still viable.

Yep, that's what I found also, LiteCoin is the way to go for normal bods.

I did some reading up the other night, set up a wallet, but failed to get the mining program running on a little 2012 server box.
