For that I would like to turn off some of the power-islands completely, so that the voltage and the frequencies of these islands are both 0. I know, that I can't do it with RCCE, because RCCE only offers a limited range of frequencies respectivly voltages.</p><p>Also if I turn off the tiles/cores like described in some other theards here in this forum, there wasn't any Information about how to turn of the voltage of the corresponding island. If i only turn off the tiles/cores, the voltage won't getting down.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;">&nbsp;</p><p>So I think, I have to do it with direct register calls. Is there something I have to take into account? For example in which order I have to decrease the frequency and voltage? etc. Or isn't it possible to decrease the voltage of an island to 0?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;">&nbsp;</p><p>It would be very nice, if someone can help me.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;">&nbsp;</p><p>Bests</p><p>Patrick</p><p style="min-height: 8pt; height: 8pt; padding: 0px;">&nbsp;</p><p>P.S.: The Question isn't really answered till now (10.07.2012)</p></div><!-- [DocumentBodyEnd:41d8110a-4ce9-40e3-9fef-b05d383e0b5d] --> Mon, 14 May 2012 08:50:54 GMT webadmin@intel.com http://communities.intel.com/message/156555?tstart=0#156555 2012-05-14T08:50:54Z 11 months, 2 weeks ago 0
