 # ComputeBlade/CM4 optimized UEFI Firmware Images

-> ** THE CONFIGURATION IS PROBABLY NOT SANE FOR ALL USERS **
+> THE CONFIGURATION IS PROBABLY NOT SANE FOR ALL USERS.
 
 This is a fork of the amazing [pftf/RPi4](https://github.com/pftf/RPi4) project, which brings a UEFI images for the RaspberryPi 4 Model B.
 
 # Adaptations compared to the pftf/RPi4 proejct
 
+## Adjustments
+- server-workload oriented -> limit GPU mem to 64MB
+- overclock ComputeModule 4 to 2.0GHz
+
 ## Ease of use improvements
 - Allow easy local builds using `make dist`
