-set CPU multi to 6 or 7, this will take CPU out of equation
-set memory to SPD and 100, this will take memory out of equation
-Increase HTT/FSB up until you fail to boot or there abouts, back down 5%, (HTT * 0.95), this is your max safe HTT.
2. Max Chip capable
- Set multiplier to it's maxium
-Set vcore to 1.6 -1.65 for 130nm chips, 1.50-1.55 for 90nm chips
-Set mem to SPD and 100, this will take memory out of equation
-starting with HTT 200 raise in about 5Mhz increments up to boards max found earlier or until you start failing PRIME95 which will probably happen first..only give it 5 minutes max, that's good enough for now.
-At the point it starts failing within that 5 min time period, back down 5%, (CPU MHZ * 0.95), thats your max CPU speed, now test prime again at 95% for 12 hour for stable.

3. Memory MAX
It depends what you want and type of mem you chose, LL or Bandwidth but must keep 1T (command rate) because A64 suffers big time with 2T.
-For high bandwidth set mem setting to 200 and 2.5-4-3-7 1 T and give it boards max volts, or for LL set mem setting to 200 and 2-2-2-7 1 T and give it boards max volts. (up to 2.9Vdimm is safe with all ram) ( Caution DFI/ABIT users -- do not exceed 3.0V unless you know what you are doing!!!)
-Set CPUs multi to 6-7, again to take it out of equation.
-Raise HTT up to boards max or until you start failing memtest86 test 5 and 6

-When you start failing memtest86 test 5 and 6, back down 5%, (HTT * 0.95), thats your max MEM speed.
