I know this has been a topic b4, and I can't find it. Plus I am on a slow a$$ PC. I plan on purchasing a XP 1600+ Retail and placing it on my Asus A7V133 MB -for my bro. I believe my MB is rev 1.04 and I flashed it with the updated bios (not sure which vers.) awhile ago. I will head home for lunch to verify what rev. the board is. This board is currently in a static bag waiting to go in my bro's PC (upgrade), in 2 weeks. I heard of some issues with XP's with this mobo, but I have seen in here that these issues have been with 1800+ and higher.. is this correct ????? Can you guys give me some advice on this? Thanks!
