In June I bought 6 modules of 168 pin 128 MB 60ns FPM 5V memory for PCI 
PowerMacs from an famous American eCommerce.

I put 2 of them to my 7200/120 and everything is fine. The Mac has been 
running with these memory modules since then.

The other day I checked the ID number of memory chips and the number was 
as follows;

MT4LC8M8B6 -5 D

>From the Chipmunk web site and the Micron Technology's site, 'L' means 
3.3 volt and it should be for 3.3 volt. As the PCI Macs should use 5 
volt, so this memory should be in a very dangerous condition. The 
Chipmunk web site says "Remember that using a 3.3 v module in a 5 v 
computer will result in the immediate death of the module. Using 5 v 
modules in a 3.3 v computer will at best work unreliable."

These memory modules are still running very well. Is there any 
possibility that 3.3 volt chips could be used for 5 volt computer by a 
certain construction method of module?
