Hi, I've got a problem with sgminer on Radeon HD5750. I'm mining quarks on p2pool and I get many many HW.
But the console is showing accepted shares.

Where is the problem?

Try without -w -g options, lower intensity.
Next add them and try some values going up.

try adding +1 to your address if its still to easy go up (+16) if to hard go down (+.1)

Having same problems with HD6770. Maybe this is a driver issue (amd_bytealign function)? Using 13.12 driver with Vista64.
No problems with mining scrypt, but have erros with sha256 too: GPU0: invalid nonce - HW error.
Quark is using SHA-3, so if amd_bytealign implemented in miner's cernel - this can be a problem, as new ATI drivers has a littlebit different amd_bytealign function...
this is an issue with too small of share size
if you can somehow get the share difficulty up to .01 or preferably above .1 the HW errors will go away
