I am sure that your friend will greatly enjoy your old SandyBridge K cpu and ram!
Hammer, There is a new setting on the CPU Volts.. There is Offset and now Adaptive. I was hopeing that someone may know how to set it properly so I can run my CPU at
a lower volt when sitting idle.
I cannot see the option for [Adaptive] for pure cpu voltage in your motherboard's manual:http://dlcdnet.asus.com/pub/ASUS/mb/LGA ... th_Z87.pdf
I only see [Adaptive] option listed under "CPU Graphics
Voltage" : [Auto][Manual Mode][Offset Mode][Adaptive Mode]
This only matters if you are using the builtin gpu ( Intel graphics ) which you are not...so the voltage sent to the Graphics portion of the cpu should not be of any concern since you are using a discrete video card.
The "CPU Core Voltage" only offers the following options : [Auto][Manual Mode][Offset Mode] , there is no option listed there for any "Adaptive mode" under that parameter.
Perhaps you have a newer BIOS revision that does offer it, ( making this manual outdated of course ), please clarify or provide a screenshot so I can see exactly what you are talking about here, thanks...
More important than any "adaptive" cpu voltage for saving power and allowing your cpu downclock to lower power/frequency when idling or under light load are the following bios options under the "CPU Power Management" section:
Enhanced Intel Speedstep Technology: [Enabled] ( self-explanatory )
CPU Internal Power Savings Control:
Power Saving Level 1 Threshold : [Auto]
There are 3 Thresholds listed there, you can play around with the values ( amperage values ) to get the best balance between power savings and maximum cpu overclock potential. Lower values = better overclocking potential, Higher values = Better Power Savings. If you are unsure then just leave them on [Auto] settings.
The other thing you can do to save power is to enable the "EPU Power Saving Mode" , although I have found in the past on my old Asus P5Q-E ( Intel P45 chipset ) that it would make my max cpu overclock unstable, so I disabled that feature in the bios but left Intel Speedstep Enabled so the cpu would clock down and drop voltage under idle/light load conditions. Rock solid stable E7200 dual core at 4.0 Ghz, ran that way for years...So you can try to enable Asus "EPU Power Saving Mode" but be warned it might make your overclock unstable...http://event.asus.com/epu/
You have already gotten the nominal max overclock out of your cpu ( 4.4 Ghz for the 4770K ), if you want more than that you will have to up the cpu voltage or go to liquid cooling etc. Remember Haswell varies more in max overclockability than Sandy/Ivy Bridge K cpu's, depends on the "luck of the draw" as to how much your particular Haswell cpu will overclock. I don't think there is "much left" in your Haswell to go above 4.4 Ghz ( if so it will come at a power cost, more cpu voltage required ). I would recommend you leave your cpu at 4.4 Ghz and 1.26 cpu volts ( "safe" voltage to the cpu so you don't fry it over time ).
The only question now is how much power savings you can get when your cpu is in idle or low-load conditions.You can play around with the options mentioned above to achieve that...
Best of luck and let us know how your tweaking goes! Cheers!
