Slow resume from sleep on Z170 Extreme7

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

I just built a Skylake system with a 6700k, Asrock Z170 Ex7, Corsair DDR4 3000 memory, and Geforce 970. It works great, but resuming from standby takes a very long time, like 8-10 seconds. Nearly the time to do a real bootup. All hardware at stock/default speeds. My last Sandybridge system took 2-3 seconds in Win7 to resume on the same SSD.  
I tried clean installs of both Windows 8.1 and Windows 10 -1511 and suffer similar issues. Resuming from standby either the keyboard/mouse doesn't respond for 5-8 seconds and then I can enter a password, or I can enter a password and I get the loading ring for 5-8 seconds. The time is always consistent. It is the same whether I have programs installed, or a clean system.

Tried Windows provided drivers and Asrock provided motherboard drivers. Geforce drivers I used 359 and older 350.12 that didn't change anything. Updated UEFI to 2.00 and 2.10 with no change.

Tried clean installs on Samsung 830 and Crucial M500 SSDs. Turned off hybrid sleep and hibernation didn't help. 

Tried almost everything and only thing left is maybe trying another board or try a Radeon. Any ideas would be much appreciated!
