*3 Limit FSB clock of this system is 201MHz.
Attention
The results displayed here tested only 1 piece from each product.
You might obtain a different result than I have. My tests used a risky high voltage for system and if you run the same tests I have using my methodology you might destroy or damage your system.
I am not responsible for anything you do to yourself or your equipment(s) if you try to emulate what I am doing.

Crucial technology 128 megabyte PC133 CL2 DIMM (CT16M64S4D7E-16T)

This product supports the fastest speed in the standard of PC133.
The Micron 7E "chip" was soldered on the board which is was created using a six layer process.May be these chips were manufactured in the second week of March of 2000.

The parameter of "SDRAM setting" is the order of CAS latency,RAS to CAS delay,RAS precharge time and MA wait state(F:fast N:normal).
The numerical value recorded in the table is the highest FSB clock frequency to be able to operate SuperPI successfully and that calculation time.
