Greetings, I've done an inordinate amount of web crawling to find an answer. I only find IDT (ICS) as a vendor and their datasheet for this doesn't show either ibis or spice models. A different ddr2 part does have models (74sstu32864), but it's not for raw card M (4 ranks). Need is for Raw Card M. jedec name: SSTU32868 4-rank drive register w/ system parity Shows up as SSTU32S868 or SSTU32D868 plus other prefix possibly, in actual vendor part #. Perhaps somebody has already traveled this nasty nightmare journey and can mercifully bequeth the results unto me. Otherwise, I'll have use the ideal-io placeholder... not good at 333.5MHz. :-) Regards, Agathon ---- ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
