Re: [ANN] YACMiner - AMD GPU miner for Scrypt-Chacha, N-Scrypt, and Scrypt coins
Thank you for keep improving the miner, Thirtybird. 
I've just updated though haven't really tried to do more tuning.
I'm getting like 1.6-1.7kh/s from a R7 240 2GB (buffer size 1752, lookup gap 3, g 1, w 256, raw intensity 1280, gpu engine 780, gpu memclock 780, gpu powertune -17), which is some way off what others are getting. I'm underclocking the RAM because performance is somehow very similar when I use stock settings.
Thats a good config. That R7 240 can clock up to 1100 MHz though, and that's where the difference is I'm sure. ~2.1KH/sec is about right for that card with a good overclock. I've found very little difference in speed with RAM speed changes - for me it's all been about the core GPU speed.
