What kind of RAC does that translate to? I have such a card for the last two weeks and it has only gone up to 5745 RAC which I think is low. Is it possible that it hasn't yet leveled? Thanks!

If you've only been running the card for two weeks, it is certain RAC won't have levelled. Don't rely on RAC alone to check whether the card is working properly: look at task running times, error rates, and validation proportion as well. With your computer(s) hidden, only you can do that - we can't help you. ID: 1461130 ·

I use this on my machines because RAC takes too long to level out because of the formula involved in calculating it. The daily delta will be bumpy (especially if you also do AP on the card, since AP WUs are not generated every day, but in bursts every few days) but it will still give a better indicator than RAC in the short run.

How many instances are you running at the same time ? I'm running 2. Don't see the point of running more. The code is highly parallel anyway and the GPU utilization is in the high nineties. I'm using the CUDA50 app from the latest Lunatics optimized apps. ID: 1461142 ·

A friend of mine benefit on a regular 450 running 3 instances. He has a RAC of approx 7K. Your card will produce more work which results in a higher score in a regular basis.
