I'm dev of XMRCGPU, Monero CPU + GPU miner.
It is combined miner with self-benchmark. After first run, it generates CFG's for CPU and GPU for almost max performance while trying not to damage your hardware
Last update brings better memory management and gives 2-3% extra hashrate over previous version.
Please test my miner and leave a feedback in comment section.
I've decided not to make 32-bit version (2GB RAM) build as these are really insufficient computers for mining .
It's falsely detected as Riskware by some Antiviruses as it's miner with command line interface so it can be turned into silent miner on victims computers.
So only the 64-bit version for Windows is for now available:
