Many users have problems with the mining YAC under Windows x64, because of low speed. I've compiled minerd under Window 7 x64 with support for SSSE3 and AVX.

Features:
- no sources, only binaries. I haven't finished it yet
- compiled under VS2010
- sha256 and scrypt not work, i haven't enough time to fix it. Only scrypt-jane works correctly.
- command line parameters supported only in Win style ("-o" but not "--url").

And some results (AVX support):
