Footyman Posted April 29, 2016 Share Posted April 29, 2016 Dominator Platinum Series 3200MHz 16gb (2x8gb) In my bios the profile for memory is set to Auto. Checking the Frequency in CPUz shows the frequency at 1066Mhz. If I enable XMI profile 1, cpuz shows 1600MHz. If the setting is set to Auto is it supposed to increase to 1600Mhz or will always stay at 1066MHz? I was thinking it would increase as and when needed and drop back as CPU does, but this doesn't seem to happen. Link to comment Share on other sites More sharing options...
emissary42 Posted April 30, 2016 Share Posted April 30, 2016 The memory frequency is static and does not get lowered if the system is in an idle state. Link to comment Share on other sites More sharing options...

Thanks, if it doesn't lower in idle when set at 1600Mhz then I assume it doesn't raise when on auto at 1066Mhz Link to comment Share on other sites More sharing options...
c-attack Posted April 30, 2016 Share Posted April 30, 2016 That is correct and the voltage is fixed as well and that is where your power and temperature "savings" would originate. However, since DDR4 typically uses a voltage in the range of 1.20-1.35v and this is considerably lower than the 1.50-1.65 of the DDR3 it's replacing, this probably is not the best place to go looking for additional savings. If you are curious, most kits can be run at 1.20v up to the 2666 MHz setting. After that, you usually need more and it is timing dependent.
