Note: Everything in my graphics is working fine right now, including 4K@60Hz, I don't have any issues whatsoever. The following question relates to how I can improve my video/graphics settings even further.
My setup only allows a maximum DVMT Pre-Alloc of 64MB in the BIOS. I was wondering, is it technically possible to push stolenmem + fbmem beyond and above that maximum? I've tried to set stolenmem + fbmem to 128MB but the OS freezes during initialization so I guess the answer is probably a big round "No", but still I'd like to hear a definitive answer from the experts here.
Here's my BIOS dump to prove that it only allows 64MB maximum. I verified that the currently selected value in the BIOS is indeed 64MB.
