Maybe I just don't know how to configure the P4c800-Dexule board. Everything is set auto and I set my fsb to 210 and it won't make it to windows.
I don't like how Asus put auto, and don't tell you the vaule. If I don't use cpuz I don't know either know what voltage the baord is set to.
go into bios
go to advanced
jumper free-
set to manual, set everything at manual.
lock agp at 33.66
raise fsb 5 at a time with the + and - keys on the number pad on your key board
keep the voltages as low as possible to start
so start like this
cpu external frequency------210
cpu ratio----------------------locked anyways you cant mess with it
dram fequency----------------400
agp/pci frequency -----------66.33
cpu vcore voltage -----------1. XXX whatever is the lowest
ddr reference voltage-------2.75
agp vddq voltage -----------1.5
on the ddr reference voltage check with the manufacter of your ram as far as what it should be at. new usually lists it.
but your probably fine with the lowest or slightly above to start
ok you got into windows at 220 fsb? its pretty stable? good.
now go back to the bios, and do this
cpu external frequency------215
cpu ratio----------------------locked anyways you cant mess with it
dram frequency---------------400
agp/pci frequency -----------66.33
cpu vcore voltage -----------1. XXX whatever is the lowest
ddr reference voltage-------2.75
agp vddq voltage -----------1.5
so you go xx5 at a time on the fsb, now you get to a point where it doesnt seem stable, try raising the ddr reference voltage a bit
still no help? raise the vcore 1 notch
dont go over 1.7 on your vcore
when your fsb gets up around where it should be for the ram your using and it seems like you cant get it stable no matter what try lowering the
dram frequency---------------400
to the lowest setting and is its stable then that tells you its the ram thats holding you back.
other random things to set in the bios.
spread spectrum- set it to disabled
try this for now. there is a lot more involved but this should get you on the right path.
im sure others will also add what else to try.
