Hello all, and thanks Claymore for new miner version!

Though, I have a problem and hopefully one can help me about that.
I got several rigs of 3x470, 4x470 (4 GB) and 4x470 (8 GB) videocards.
After updating the Claymore ETH from 7.4 version to 9.0 I got a strange problem.
Decred increased *2, that's a fact, but hashrate of both ETH and DCR became floating. Usually my cards give 21 or 24 Mh/s (nothing is overclocked/modded, all stock) depending on whether its Asus strix 4gb or Sapphire nitro 8gb, but now once in several seconds one or two cards in the rig drops hashrate to 17-18 mh/s on eth and to 400 mhs (instead of usual 600 mhs) on dcr.
That's how Afterburner log looks like: http://img.imgland.net/aT4LZLU.png
on 7.4 there were no peaks, no nothing.
ASM is ON. If I turn ASM off - everything's fine.
But hey! Isn't it all about ASM = on and having *2 DCR increase?

If anyone has such a problem and solved it - I'd be grateful for help.
