You can "edit" your post if you want to add anything.
small update:
maybe the 7950 vapor-x is only voltage locked on one of its two bioses. can anyone confirm?
Another question: do boost models come with higher factory voltage? that would be bad for my undervolting idea...

I came across some info that sapphire 7950 vapor-x have the voltage locked. does that mean that they don't work well for undervolting? or was that just a tempory (software update) thing?
Hi,
i am not completely new to bitcoin, but have left over a year ago due to personal reasons. Now I am back and overwelmed with what has happened in the meantime.
Now I need advice on Hardware for BTC/LTC (mainly LTC) mining that gives best Hash/Watt since I live in Europe and pay ~0.27€/Kwh (yeah, green energy^^) LOL
(don't tell me that I will pay more in electricity than I will gain; I know that might happen most likely)
I plan on starting with a single 7950 (saphire vapor x) and see how things work out. maybe adding 1-3 of the same later if i am satisfied
(8GB Ram, Semperon 145, ~1000W Platinum PSU)
I stumbeled across asrock mainboards, mainly the 970e4 as a recomendation, but whats the main difference to the 990?
Which hardware gives me the best Hash/Watt
How is the spacing on the mainboards; do i really need risers? is would prefer an "almost" closed from the rig casing.
What ist the power consumed by the mainboard? I figure that the 7950s may be around 200-250W
any help/advice in undervolting? optimizing for Hash/Watt?
Any comments? Help?
cheers.
