Hi joblo,
Currently testing the cpuminer on an Intel(R) Xeon(R) CPU E3-1230 V2 @ 3.30GHz ..
Running using Fedora release 20 64bit .. a bit outdated as I'm too lazy to upgrade it as there are a lot of things running on it..
So far it is doing quite well but I keep getting "Result does not validate on CPU!" ..
EDIT2: Tested with x11, X13, X15, Quark and Qubit algos.
Will keep you updated as each test takes a while to get any accepted..
