Hi,
you know, that it is normally not possible to answer your questione with this information !
Normally I'm using all different search engines and just type in some parts of the markings. But Metacrawler found nothing, so I don't want to spend so much time.
But you can still try !!!!!
The only way to find out is to read out the SPD EEPROM, because there it should be programed which CL the Chip is doing @ 133MHz.
try the c't tool ctspd
ctSPD
it will tell you (and decode) the content of the SPD
