I saw the notices at btcguild about this problem, but I did not have any problems, but then I introduced some new hardware, (7970) had some driver issues and decided to do fresh install...
big mistake
luckily my guiminer was "installed" on one of my storage drives. took a while to find it but it still works, it says V 2011-07-01
**only works for my old card 5850, does not seem to work for 7970, on my way to look for a solution for 7970 mining, if anyone has an *easy* option, it would save me a ton of time
***EDIT*** I'm dumb, just installed java and now it works for the 7970 as well, using phoenix atm, just cuz that was the last one I tried (and failed) before I installed java... no idea if others are better or worse, no idea what to use for flags, but just getting this card working makes me happy in my pants
**second edit** seems pheonix is the only one from the 2011.07.01 guminer package that will get me hashrates on my 7970, it gets around 450-460 MH/s but only runs the card at 80-85% avg.. if anyone knows some proper flags to use for this card and this miner software, please PM me, if I find something better I will post. Thanks.
