The graphics embedded in all 6th gen Core processors is the same even the mobile version: Intel® HD Graphics 530
Now, in regards to your case, the issue could be related to the memories. The 6th gen processors support RAM of 2133MHz.
I suggest you to make a test using motherboard, CPU, 8GB of RAM at 2133MHz and try to install OS.
Note: this motherboard has the option to overclock the processor, turn the option off.
