Hello.

I am currently working on an "easy button" for cgminer and litecoin newbies.

Essentially I am going to modify cgminer to be ran with one simple config file where minimal input is needed from the user.

I am going to make cgminer "auto tune" based on a couple of variables to adjust for engine/memory speed automatically for best hash rate and shares submitted.

One thing I am having an issue with is the correlation between GPU and computer hardware and settings in cgminer.

All I would like from you is your system specs and your cgminer settings, this should help me find some kind of correlation.

I've also found that on some systems there is a ratio of engine speed to memory speed.

Mine is 3/5, for every 3mhz engine increase I needed to increase memory by 5mhz to keep it stable and increase hash rate with an intensity of 13.

So if you have a second please submit this data.

Thank you.



I saw this the other day on the litecoin forum: http://forum.litecoin.net/index.php/topic,67.0.html
I think it's pretty similar to what you're doing. The guy also has no problem from someone picking it apart and taking all the data.

That's great.

Everybody's settings are different.

For instance I can up with this for 7970s, I verified it works and so have a couple others.

I want to do the same thing for other cards so it will be easier for people to optimize their settings.

I am looking for patterns in settings in relation to cards.

Just trying to help the community out because a lot of new litecoin miners aren't used to the difference from Bitcoin.

Thanks tho.

Code:
rem start /D "C:\cgminer" cgminer.exe --scrypt -o stratum+tcp://notroll.in:3333 -u user.1 -p 12345 -d 0 -d 1 -d 2 --thread-concurrency 8000 -I 18 --lookup-gap 2 --worksize 256 -g 1 -d 0 -d 1 -d 2 --gpu-memclock 1200,1200,1200 --gpu-engine 925,925,925 --gpu-fan 55,55,55 --gpu-vddc 1.20,1.20,1.20

For Asus HD5870 (EAH5870 v2), very stable and temps are good.
Avg. 1320 Khash/s for 3 cards total.


If you like to thank me, considder a LTC donation @ LUXNPiFYx8KZbnmhoEoywQayvCyMB9yp3k
