Overclocking A64 3000 neo4

[Omnikron]

I can set the FSB 225 HTT x4 , CPU Mult x8 , CPU Vcore 1.40v , add volt 6.6 , Mem volt 2.70, chip volt auto, mem clock 166 , Cas 2.5, 7,3,3
and it boots fine to window xp so I dont think I have that FSB 219 bug . But I cant seem to go FSB 226 it lock ups is there any other setting that I might give a try
My temps are good are 38 idel.

try setting HT to 3x and it should allow you to go up.

Shouldn't need to drop the HTT multi to 3x till above 250 to 260 HTT.

Try raising the voltage on the memory to 2.8? I know that helped my overclock out a bunch. Maybe loosen the memory timings slightly or try using a divider. That way you will atleast be able to determine if it is your ram that is keeping you below 226.

read my thread, its the HTT doing it. Its bugged in the bios. Lowering the HTT will fix your problem or you could ultimately use clockgen and bypass the bios settings altogether.
