Hello, I am currently mining with a hd 6670 which sole purpose was to be a cheap and lite video card for modern gaming.
http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-2.html Little did I know for 54 bucks I could use this card to start mining my very first bitcoin. I am currently running at 121.5 Mhs using guiminer-phoenix:ASKRATE=1 WORKSIZE=128 VECTORS BFI_INT FASTLOOP=false AGGRESSION=5. sdk 2.2 catalyst 11.4 winxp 32bit over clocked 800mhz-850mhz 667mhz 2gb ddr3.
That seems the be the sweet spot that I can find using windows xp. sdk only supports up 2.3 for xp and I read that 2.1 is fastest. personally I just used 2.2 and it seemed to yield good results. Also I forgot to add in, my aggression is 5 because for some reason that is the sweet spot being1-4,,6-13 yield no hash increase with obvious framerate drop with higher aggression. Im not sure what that means but im sure someone could elaborate to me what each level of aggression is doing to my video card and why im not seeing an increase. I dont use phatk or phatk2 kernels because they only result in drop of hash speed. From what I've gathered at wiki I should be seeing 120 so I shouldn't complain and I'm not in fact I consider myself lucky being at aggression 5 I am able to use my computer like completely normal and depending on which kernel I use poclbm or phoenix Im even able to play some games. I keep my video card under 60c being hot to me and around about 55c and under. I want to use windows 7 64bit os to mine for various reasons. I can't achieve the results in win7 as I do in xp. I am about 10-15mhs lower in win7 64bit. I would also like to consider using a flash stick to boot to for mining when Im not using the computer my only problem doing that is I have read that the number of read and writes a flash stick can do is limited. From what I understand they could wear out? Maybe this is something I read blown out of proportion? In any case this is my setup for now, I would like to start using windows 7, any sweet spots for you may work for me so im interested in whatever your running more interested if your running 6xxx most interested if your running a 66XX and you got my full blown attention if your running a 6670 2gb ddr3 800mhz core
Im just starting out, Iv been mining for a couple of weeks, done tons of homework and I wish I had at least one 5970
Thank you for reading, and your time. I value your input and pardon the grammar and spelling errors.
