to see if it's 100 or 133 MHz you look at the part number ... it should read A1200AMS3C if it's a 133MHz part and A1200AMS3B (here using the 1200MHz Tbird as an example)
About the "Malaysia"... it arefers to where the chip was packaged (where the die was mounted on the ceramics) .. happens at AMDs plant in malysia. What you refer to about Germany is where the core was fabbed, which canbe either Germany or Austin,TX. The difference is that German cores are fabbed with copperinterconnectors while Austin parts use aluminium. Supposedly the copper should be better for overclocking, but AFAIK there's not any sure way to tell them apart these days (I believe the die polish color trick is no longer valid)
