Ok here is my problem:
I tested mining on any 58xx 5970 and now 69xx I can get.
But the 69xx are so fuxxing slow.
What people say in the wiki (
https://en.bitcoin.it/wiki/Mining_hardware_comparison) isn't what I get.
My 6950 does 330Mh/s my 6970 does 356Mh/s and this is clockt to 930Mhz.
My test-setup is Win7 with catalyst 11.5 and GUI-Miner.
In the wiki they all are using vectors, that works on my 5xxx cards but my 69xx all slow down if I enable vectors. Is the a problem with poclbm2011.beta4, are they stupid or am I?

Thx
Without using the -v -w128 flags I got the same speeds.
