I don't have any good experience using these adapters, I've tried one of these out of curiousity on two rigs (Intel P45 and some strange ULi chipset), either the cards won't POST at all/doesn't get recognized by lspci, boot up/run X11 but get instantly flagged as DEAD by cgminer or sometimes get stuck/SICK and cgminer needs to restart the GPUs.

GPU temperature -> the lower the better (less leakage currents -> reduced power consumption)
fan speed -> the lower the better (cheap sleeve bearings...)

So I've recently put my rigs on the balcony, got me into the range of 40-60% fan speed and 30-50 °C GPU temp (before: 70-100% and 60-80 °C), reducing the total power (at the wall) by more than 10%.

Three boxes w/ ancient PSUs and Celeron D / AMD X4 space heater CPUs. Thinking of moving over to undervolted 5970s land..

Nice work!

Deneb C2 @ 3.7 GHz / 1.45 V mining LTC vs. old sh***y AM2 mobo
1 : 0

At least now I've got a reason to build a nice new 2600k machine.

Atom 330 @ 2.16 GHz:
- 4 threads, 0.66 kH/s each
- 2 threads, 0.91 kH/s each

Phenom II @ 3.6 GHz:
- 4 threads, 3.62 kH/s each

Core 2 Duo (65 nm) @ 1.5 GHz:
- 2 threads, 1.35 kH/s each

Debian/sid x86_64, latest cpuminer, CFLAGS="-O3 -march=whatever_cpu"

ofc, but these 140 were mine up to some minutes ago.

140 blocks orphaned, wtf?!

...and every new block disappears. 

Exactly as with Bitcoin or whateverfailscamundeadgetrichquickcoin:


Needs of course a client or daemon running on the same machine.

400 SPs running at 600 MHz, expect something around 60 - 80 MH/s.

I'm running mainly reused old LGA775/AM2 stuff, except the ITX box with that uber 1337 keyboard. Didn't had to buy anything besides GPUs and two cheapo Celeron Ds (underclocked to 2 GHz / 1,1 V).

I promise, I'll buy some decent cases if this still gives some profit in 3-4 weeks.

5!

Get some machine running bitcoind/namecoind and put something like this in your bitcoind.conf:

rpcuser=user
rpcpassword=pw
rpcport=8332
rpcallowip=[put your miner's IPs/ranges here]
daemon=1
server=1

rpcuser and rpcpassword ofc have to be changed.

After dl'ing the blockchain, point your workers to the server's address using the username and password specified in your bitcoind.conf.

Example using phoenix/linux:

python phoenix.py -u http://rpcuser:rpcpw@server:port -k yourkernel DEVICE=x [additional flags]

btw. by using bitcoind's "generate coins" stuff, you're basically heating your room (aka CPU-mining).

They usually take the transaction fees for themselves.
