[OLD SCHOOL]pentium mmx166@420 mhz and tualatin 1300@ 2388 mhz ln2

With 2 volt and a tb1 I think a shoot@2550mhz is possible.

for 2550 you need cpu@2250-2300 on SS. vmod for tusl work normal up to 1.9v on this clocks. on screen you have 1.8v, its 1.85-1.9v real.

you have great tA1, not all tB1 can do 2300+. i dont think tis cpu http://www.hwbot.org/result.do?resultId=558437 can run 2450+
