Hello,i just built an other one  my little mining rig ,guys i cant believe but 2 MSI 7990 running 1.447kh/s  and other 1451kh/s but problem is temperature, I dont know but one of them runing 77C other one 79-82C, isnt that temperature too high for long run ?Anyway im gonna get cooler to keep them more cooler and i noticed they are a little bit hungry,eating almost 400w each card but 1.4kh/s i hope i wont have problems in future.How do you think do i need buy powered risers to split them away ?If you have good cgminer scrypt for these cards please write down ,i need average kh/s but maybe yours scrypt keeps temperature down

Unlike traditional banking where clients have only a few account numbers, with Bitcoin people can create an unlimited number of accounts (addresses). This can be used to easily track payments, and it improves anonymity.
