Hello everyone, my first post! 
I’ve just built myself a nice shiny new AMD Ryzen 1700 system opting for the Gigabyte Aorus Gaming 5. Sadly upon getting to enter the UEFI I found it to be completely bereft of any meaningful options and the state of the UEFI is so bad it doesn’t even look like the UEFI has left alpha stages of development. I have already significantly improved it and am currently running my own modded version of F5c, there is still at least one problem I would like to address though and I’m hoping someone here can help
I think I know which module in the UEFI holds all the information for memory compatibility - AMDMemS3CzDxe, but I’m not totally sure. So my request for help is 2 stage;
- Does anyone know for certain if AMDMemS3CzDxe does contain the memory compatibility information
- Can anyone help with injecting a AMDMemS3CzDxe I’ve taken from the Asus ROG Crosshair VI, it’s slightly larger (107kb) and MMTool keeps giving me a error about it being too big 
For reference, here are the things I’ve fixed / changed so far:
Enabled “Host Clock” for clockgen hardmods
FIX: Removed duplicate “XMP” entry - It’s now just in "Advanced Memory Settings"
FIX: Removed duplicate “Memory Multiplier Entry” - It’s now just in "Advanced Memory Settings"
FIX: Removed duplicate “Memory Frequency Multiplier” entry - It’s now just in "Advanced Memory Settings"
Advanced CPU Core Settings:
FIX: Removed duplicate “CPU Clock Ratio” entry - It’s now just in "Advanced Frequency Settings"
