I am happy with the A7V133 1004 BIOS. I pulled one of my 3 Crucial 128MB CAS2 RAM sticks, and added one of the Infineon 256MB sticks that I had trouble with before, and it now shows the correct RAM amount, and is working well with the Crucial at 148MHz
2-2-2.
That was my major complaint with the board, and am glad that ASUS sorted it out. I have not checked my Mosel Vitelic out yet, but it should work fine also, since it had the same issue as the Infineon.
