It was just a general question really on the possibilities over over-stressing the cards with that setting. Obviously the technology behind the coins matter so thanks for moving my thread.
I am running Sapphire R9 290's some recommend them to run on 2 GPU threads but I find the hash rates fluctuate a lot sometimes 50-60hashes per card, so I have remained on 1 GPU thread for now.
Am I right in saying that if I ran them on 2 GPU threads I could actually lower the intensity? On paper that would maintain the same hash rate but isn't a given RULE as such as it depends on the hardware?
For 290 run it with 1 thread and 20 intensity (maybe tweak if not mining standard scrypt), the fluctuating rate of 2 threads will not average out any higher.
