Title: CGMiner Invalid config option --intensity: Invalid value passed to set intensity
Post by: sheinsha on June 02, 2013, 07:45:15 PM
Hi, im getting "Invalid config option --intensity: Invalid value passed to set intensity" when i set intensity 15+, it is ok with 14.

Mining BTC
I have 2x Sapphire 7950 Vapor X.
CGMiner version 3.2.0

If i mine LTC (with cgminer ./configure --enable-scrypt) i can set it to intensity 20 without any problems, getting 660kHahs/s each card so its not a hardware problem.

Has this happened to anyone already?

Thanks in advance!

You don't want to go over an intensity of 9 when Bitcoin Mining

>> --intensity|-I <arg> Intensity of GPU scanning (d or -10 -> 10, default: d to maintain desktop interactivity)

>> NOTE: Running intensities above 9 with current hardware is likely to only
diminish return performance even if the hash rate might appear better. A good
starting baseline intensity to try on dedicated miners is 9. Higher values are
there to cope with future improvements in hardware.
