Hi; I have the 102 page Intel Data Sheet in front of me. I am trying to determine the High and Low voltage numbers for transistors on my system. I am not trying to do anything mysterious or build a CPU in my garage. I am just doing a small write up for myself that has an introductory paragraph for a section on how DRAM memory works that says something like "My machine's CPU and Memory transistors typically use XXX volts when thrust High and XXX volts when driven Low." I understand that things can get more complex, but I am only trying to establish a sense or feel of what is happening inside, not write a technical manual for engineers. All the various Vtt, Vcc, Vss, VID etc. are getting confusing. I will either have to spend a couple of days googling trying to interpret the Data Sheet or take a short cut by asking here. What designation or parameters should I be looking at for high and low voltage (logical/binary 1 and logical/binary 0)? I am using the Intel 318732.pdf {Core 2 Duo Processor Data Sheet}. lshw says I have a: product: Intel(R) Core(TM)2 Duo CPU E7400 @ 2.80GHz vendor: Intel Corp. bus info: cpu@0 version: Intel(R) Core(TM)2 Duo CPU slot: Socket 775 size: 1600MHz capacity: 4GHz width: 64 bits clock: 266MHz -- Regards Bill Fedora 11, Gnome 2.26.3 Evo.2.26.3, Emacs 23.1.1 -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
