Hello, guys
I have this kind of problem
My rig with 1x Radeon 7950 and 2x 5870 worked fine with previous algorithms of Vertcoin and other coins.

After the recent algorithm switch 7950 keeps working, giving ~3.4 Mh and ~12.5 of WU (intensity 19, worksizes 32 - 256 all work)
Both 5870 give just HW errors and around 1.7 Mh of false hashrate, doing nothing.
I tried changing the intensity, worksizes, clock and memory speeds - nothing helps. Also put the --no-extranonce flag.

Pool: give-me-coins, --diffuculty-multiplier is set to 2
ATI (AMD) Driver 13.12. Also tried above mentioned DLLs from 14.4 in the miner folder.
sgminer taken from official website

Did anybody get the 5870 running?

Did anyone get older cards working? I have an 6970 (6950 with shaders unlocked) and am only getting hardware errors. I have a 280x in the same rig and it's working fine. please help! I am currently using PIMP 1.6 with AMD 14.6 Drivers and I complied the updated sgminer as of 17 hours ago. I've tried multiple combinations of intensity, worksize and TC with no luck. It's hashing at 2Mh but nothing accepted and lots of HW errors.

Same thing continues. Also tried p2pool & solo - while 7950 works, older don't. I guess people with R270 had the same? I have no idea what's wrong with older/weaker GPUs.

By the way, I want to thank the developers for fixing getwork local protocol for solo!
