Title: Energy saver
Post by: DeadHead on May 20, 2015, 09:57:42 AM
Hi! A few questions about energy saver:

1. Would it be possible to park even more cores than default while in energy saving mode? On my processor, 4 cores gets parked (out of 8 HT cores). So, possible to park say 6 cores?

2. Would it be possible to lower cpu voltage while going to enery saving mode? My old 920 needs a bit more juice when running overclocked like I do. In enery saving mode, core frequency goes down, and so shouldn't need the higher voltage then. Or is this only a bios setting?

Both are possible, but #2 is not realistic since it requires a kernel mode driver and would add excessive complexity.

#1 simply requires adjustment to your core parking settings. Whether your BIOS/UEFI, Windows, or CPU ever allow more cores to be parked than 50%, I don't know, but you can tell it to allow more cores to be parked.

See our page about ParkControl (https://bitsum.com/about_cpu_core_parking.php)

Not sure about this, but I remember I did park more than 50% core.
Because the user's laptop that I am tweaking is 4 core 8 threads, and it is Windows 7, because of the hot apple, so I just parked the Core and left 1 core running.(As windows 7 will only park the HT thread)

QuoteSpecify whether the core parking engine should distribute utility across processors.
Maybe this one? Try this one first.
You can found it just at the same registry folder as Core-Parking, which is under the CPU folder. :)
