http://finance.groups.yahoo.com/group/Silent-PC/ Group for exchanging experiences related to silent personal computers Tue, 01 Jul 2008 01:04:22 GMT David Neeley http://finance.groups.yahoo.com/group/Silent-PC/message/13240 http://finance.groups.yahoo.com/group/Silent-PC/message/13240 What about the 45 nm processors ("Wolfdale") now appearing? IIRC, one example is the E8300...has anyone any experience with undervolting these puppies? Since Mon, 30 Jun 2008 04:45:07 GMT John Paterson http://finance.groups.yahoo.com/group/Silent-PC/message/13239 http://finance.groups.yahoo.com/group/Silent-PC/message/13239 There is another reason for reducing the voltage; but it is not usually a user determined function. If you are trying to switch a transistor from "on" to "off" Mon, 30 Jun 2008 03:16:37 GMT terramir http://finance.groups.yahoo.com/group/Silent-PC/message/13238 http://finance.groups.yahoo.com/group/Silent-PC/message/13238 Why backwards I said frquency does not reduce heat as much and voltage decreases I forgot the square, but in the real world I have not seen a square reduction Mon, 30 Jun 2008 03:10:34 GMT Chris Thomson http://finance.groups.yahoo.com/group/Silent-PC/message/13237 http://finance.groups.yahoo.com/group/Silent-PC/message/13237 Well, that's backwards. CPU (and any other semiconductor) power consumption is linear with the formula V*V*F, that is, the square of the voltage times the Mon, 30 Jun 2008 01:58:41 GMT terramir http://finance.groups.yahoo.com/group/Silent-PC/message/13236 http://finance.groups.yahoo.com/group/Silent-PC/message/13236 Q:> I only have one question - why undervolting? ... A: Because heat generated is a function of clockspeed and voltage, the less voltage you feed a processor Wed, 26 Mar 2008 03:21:02 GMT Naoyuki Tai http://finance.groups.yahoo.com/group/Silent-PC/message/13235 http://finance.groups.yahoo.com/group/Silent-PC/message/13235 ... I settled on GIBABYTE EP35-DS4 (rev 2.1) 1) CPU voltage control down to 0.75V (which is what I found on the web and reason I chose this one) 2) The BIOS Thu, 13 Mar 2008 23:35:16 GMT Dave http://finance.groups.yahoo.com/group/Silent-PC/message/13234 http://finance.groups.yahoo.com/group/Silent-PC/message/13234 What I did was use the least expensive 45 nm Core 2 Duo I could get my hands on. Using these and under voltaging I'm almost tempted to replace the heat sink to Thu, 13 Mar 2008 13:54:31 GMT Chris Thomson http://finance.groups.yahoo.com/group/Silent-PC/message/13233 http://finance.groups.yahoo.com/group/Silent-PC/message/13233 All Core2 Duo CPUs will run reliably at 1.05V at 6x clock. This is the EIST voltage/clock setting. Most chips can improve on this. Most ASUS, Abit and Gigabyte Thu, 13 Mar 2008 08:15:06 GMT Gwenn Boussard http://finance.groups.yahoo.com/group/Silent-PC/message/13232 http://finance.groups.yahoo.com/group/Silent-PC/message/13232 ... Undervolting -> less consumption -> less heat -> less fan (in speed or number) -> less noise -> more silence I'm interrested in answers too...

It looks like a promotional msg...

Is this an authorised send through this group? I understood it to be exclusively for peer to peer help on creating and using Silent PCs?
