I'm getting public work, but ~35% (!) rejects. Anyone else experiencing this?
One of my rigs with 1.7 GH/s running Phoenix 2 is getting 90-100% rejects, also tried phoenix 1.7.5 which got 100% rejects. On a rig with 235MH/s, phoenix 2.0 is running fine, but on newer drivers... Rig with 1.7GH/s is using 5870s/5970s, so if I update the driver I will lose a signifcant amount of MH/s. Also, I am not convinced this is driver related.
Have a rig with 1.5GH/s running DiabloMiner 11.12 drivers, which is getting an acceptable amount of rejects, but GPU usage is all over the board, jumping between 0 and 100% usage, and everywhere in between, in no particular order on all of my GPUs, this is resulting in about a 20% decrease in hashrate

Have a rig with 2.3GHs, using 7970's and DiabloMiner, which also has GPU usage problem, but much worse, resulting in about 50% decreased hashrate.
About a day ago, my rig with 1.5GH/s was working just fine offline, since public work resumed over the past however many hours, this problem started occurring.
I am curious why DiabloMiner, which is not listed as supported by GPUmax, works better than Phoenix 1.7.5 and 2, which are listed as compatible...
