I have been LTC mining using CUDA miner with my GTX 280s for about a week.
Windows 7 64 bit - Core i7 965 Extreme - 12GB 1600 MHz RAM - 240 GB Intel 520 SSD
Today I got my Saphire 7950s in and I installed two of them (still waiting on risers). No overclock yet. 925 MH/s
I installed the AMD 12-10 drivers. I read these were good drivers for mining LTC. Is this correct? I do not have any SDK installed. Do I need the SDK? If so exactly which one do I need? I cant seem to find anything that I am sure is the one to use.
I started up cgminer with cgminer.exe -o
http://mine.pool-x.eu:8080 -u XXXXXXXXXXXX -p XXXXXXXXXXXXXXX which is my LTC pool so obviously it rejects all of my shares but it does say I am getting just under 500 MH/s for each card.
So I started it up with --scrypt, specifically cgminer.exe -o
http://mine.pool-x.eu:8080 -u XXXXXXXXXX -p XXXXXX --scrypt
to mine LTCs and it works but I only get 15 KH/s per card.
I also tried cgminer.exe -o
http://mine.pool-x.eu:8080 -u XXXXXXXXXXX -p XXXXXXXXXX--scrypt -I 7 Same thing. 15 KH/s
So,
Are 12-10 good drivers?
Do I need the SDK?
Should I be using cgminer to mine LTCs with 7970s?
If so what am I doing wrong?
Any help is greatly appreciated.
Thank you
