Yup so title says most of it.
Long story short, saw bitcoin way back when. Thought "wow that is neat". I'm pretty sure I got a couple of coins after lots of mining. Then decided to go look at how much they are worth, awww. why bother even transferring them out.
Fast forward to a month or so back - "Wow, wonder what my wallet address is, or my password...crap." Well I wasn't counting on it, c'est la vie.
Anywhos, I was in the market for a "budget mid range GPU and saw the r9 270x and was impressed for the value-not expecting the world either. Since it was an ati, figured I'd give a shot at mining.
First go with litecoin and cgminer - about 290kH/s - well I figured I could do better and read and followed the readme.
Here are my settings -- YMMV
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
"C:\Users\YOURPATH\gminer\cgminer\cgminer.exe" --scrypt -u USER -p x -o [Suspicious link removed]:8888 --gpu-platform 0 -d 0 -w 256 -v 1 -I 18 -g 1 -l 1 --shaders 1280 --temp-target 77 --temp-overheat 81 --temp-cutoff 85 --auto-fan --auto-gpu --gpu-engine 840-1100 --gpu-memclock 1450 --thread-concurrency 14208 --no-submit-stale
That gives me about a 400-450 kH/s average drawing about 230w (old ass core-duo and windows
. Anytime I start pushing the memclock or gpu engine much more I get little hashrate for the instability (about 4hrs max, before the driver dies). I know a lot of people are poo-pooing the R9's, but I am impressed for a $200 card. I am still working on the settings periodically and am hoping for about 450-460kH/s stable, so for about $600 -> 1.2+ mH/s that's not a terrible value from what I'm seeing on the market now (pretty sure that beats the r9 290x kHs/$.)
Just a lil FYI - hope someone finds this and can benefit from it as well.
