And please: do not just delete started work units.
Those WU are sequential in nature and if one got stopped the subsequent WUs can't be created and research get delayed. Once a WU is started please finish it ! also if you get less points.
If this is done to often it will harm this coin with respect to its reputation.
Oh, and it might harm the status of your own passkey as you need to keep a 80% success rate on returned WU to keep the QRB
This is true and I can verify this. Dumping work units will lower your points. I know many of you are still learning how to get rigs that are built for mining to fold. In some cases this will be impossible because many miners have too little CPU power to feed work units to multiple gpus. ( many miners built machines with cheap cpus because a high end cpu is not needed to mine coins via a multi gpu setup)
If you are bottle necking because of too little cpu power you might want to consider buying a cheap quad core or eight core processor providing that your mobo can handle it. As mentioned in other posts you will want to leave atleast one cpu core per gpu plus an additional left over cpu core to prevent this bottle neck. If you want to go all out and run 4 gpu's on a quad core system post your results. If you have a fast enough ghz cpu you might be able to pull that off, however in most cases a single spare cpu core is needed.
ChristianVirtual is a pro folder, he has mentioned QRB ( quick return bonus ) and the fact that you have to have an 80% success rate in returning work units in order to receive this bonus (QRB). If you want to get the full potential earnings from your gpus then you simply must learn how to work with the QRB rules. Take his advise, and learn how to earn quick return bonus (QRB).
To give an example of the loss in points due to QRB rules, one of my gpu's is folding a work unit with a base credit of 4000 points. Since I'm meeting the qualifications for QRB I will receive around 27000 points for this work unit.
To add a little encouragement to upgrade your cpu, take a look at this... Congrats Team Curecoin members, we have reached the #1 position in current folding speed at this time less then a day after official Curecoin launch. That is something to be proud of. These work units are not normal SHA or SCRYPT algo's. These work units can lead to cures for a variety of illnesses that most of us have seen effect someone's lively hood, and even take their lives. "Folding, because mining gets boring", or look at it this way " Folding, as if it may save your life some day".
