Thanks you all.
Im currently using
+ 150 core
- 200 mem
90% power
80% Fan speed
I got abt 20mh, but dont know if this setting is good. Got worried on the card.
Try dropping your memory to -500 and power to about 80%. You will probably see next to no change in MH but you will be using less power, your fan should drop a fair bit and the GPU will last that little bit longer.
