well, let me recall back what OPB said before. (not applied to nf4 non expert or venus)

1. Don't set MAL and RP under bios. You have to set AUTO.
2. IdleCycle Limit - set to auto under bios to boost MAL tighter.
3. If go higher fsb, then DS can go with 1. DDS sometimes can be tricky, if you have very strong ram, try 3 first, but always from auto, then if safe, go 2 then go 3, normally 2 is just perfect for average users.
