OGN, as for you, I would try flashing the BIOS with the newest release for the A7V. I think that the new ROMs fix issues like that. As for me and the KT7-RAID, I fixed the problem, finnally! THere are many reasons that the KT7-RAID might have these problems. One in ACPI. The other issue, which affect me, is the I/O Volatage. For some reason, the default voltage, 3.30V, is too high or something. By entering SoftMenuIII and lowering the voltage to 3.20V fixed the issue completely. Did comprehensive tests and am positive this is the case. Go figure. By I am now running fully stable.
