hmmm, I saw these logos here:

while we will not infringe the copyright, we can create some similar logos with some differences. Anyone good at graphics want to try? I up'd the bounty to 200K GRAs for designing our future logo for GRA.

Yeah I just threw those together from random sites around the internet trying to get some ideas and see what people liked. It seems split on colors (if natural brown grain colors are wanted or something more colorful like the yellow/green). Didn't really see mention the grain border vs plain border so not sure about that. It does appear that people prefer a stylized image of grain rather than a realistic one.

I'm no graphics designer but I threw this together in Photoshop earlier. I have it in high res and can change the colors at will to whatever (I can move the grains around to different angles as well, that just seemed the most visually pleasing). I tried to keep it simple but is this design liked at all or should we be looking at something closer to the previously pictured designs?

What hashrate should I expect with 7950 GPU? Right now I am getting ~60 KHash/s with cgminer

thread concurrency: 24000
worksize:256
vectors:1
intensity:12
gpu threads:2

Is that normal for this or completely way off? My GPU temps are not maxing, maybe at 60-70% temp Sad

Thread concurrency overrides most of those settings anyway. This is what I have my 7950 mining.bat file set to:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o localhost:11055 -u user -p pass -I 20 --thread-concurrency 24576

Technically you don't even really need to set thread concurrency, cgminer does a decent job of doing it for you. If you really want to push it to the max you multiply your bus x 64 which gives you the TC #. I pull roughly 550-600 with mine but I have cooling issues (need to invest in some water cooling eventually).

Be sure to delete the "scrypt_morewordshere.bin" file cgminer creates every time you change a setting in your .bat file too as cgminer will ignore your changes and use the .bat otherwise. Another trick is to look at the words in the .bin file's name. It'll tell you what TC and Worksize and etc. it's using (should look like scrypt...tc24576w256l4.bin).

One last thing is to be sure to use cgminer 3.7.2 or earlier as any version after that has scrypt taken out of it and is useless to us.
