Today I was in my case switching A differnet fan on my HS. Before my config had my Athlon XP 1700 T-Bred running at 1738 on a MSI KT3 Ultra 2 running at 158x11 and some PC2700 RAM at 2,2,2,5. This was at optimals setting VCore 1.6 V dimm 2.7 It was running great. Now after reconfiguriing the fans it won't boot at this any more I even switched back to what it was. When I check the motherboard led lights in back it says it has a problem initializiing the IDE channals. How could this happen? It boots fine with 133 all the way to 145. but NO highier what could have happen? =(
