 Copy the 1500 strap value up to the 1625, 1750, and 2000 levels, for both. You have two bios and thats modding both if you dont know which you are using.

No he means the bios has straps for 2 types of memory.

Elpida should be the second one.

3 options
1. Use DDU to remove drivers and then install 16.11.5
2. If using this driver or a lower revision simply re-install
3. If you want to use newer drivers make sure they are pixelpatched to bypass the driver signature check.

it seems who with this crimson version the problem is already fixed...
do you think is not true???
but the message i get, it is symtomatich of driver signature check?
thank you
