Hervé is right. You'll need to set the DVMT and CFG Lock.
For my 7040 MT, I had both cfg lock and DVMT pre-alloc set with the following commands respectively using modgrubshell.efi
setup_var 0xAF 0x0
setup_var 0x350 0x4
After the changes, disable the following in config file
framebuffer-fbmem
framebuffer-stolenmem
Did you upgrade to OC 0.7.6 and update all the kexts?
I see you have UpdateSMBIOSMode = Custom, you need to pair it with CustomSMBIOSGuid=Yes under Kernel\Quirks
MacBookPro15,3 is also wrong for Skylake, should stick with MacBookPro13,1
Looks like you made some updates to the config with settings from 0.7.6 but your files are kept at 0.7.5. It's a no no. No mixing of files.
Give this a try
Precision 7510 HD530 Only OC 0.7.6.zip
I see you're using an USB wireless card.
In the BIOS, disable the following:
Wake of LAN, WLAN, WWAN, USB, Bluetooth, AC under Power Management and Wireless tab
You need battery status working to enable the touchpad preference, strange how that's even relate.
Anyway, you need to add SMCBatteryManager.kext to fix that issue.
