And that's the mystery, what are the minimum PC components required by nicehash miner

AMD Athlon II X2 4450e (unlocked 2nd core of a Sempron 145) and an AMD Radeon HD 7700 with 1024 MB. Neither one will complete the benchmark for equihash. Usually the equihash GPU benchmarking crashes my PC. I've got 4 GB RAM, maybe I need more. Other more powerful CPUs have no problem running on 4 GB RAM and say they only use less than 50%. I'll try making it 8 GB and see if that helps.

Another thing that's driving me crazy about NiceHashMiner 1.7.3.3 is that it often starts running and stops while loading SMA saying that I need to have an internet connection. The internet connection is always there and no other application has any problem using it.
