Hi it's the stock build from the excellent guide. The memory is 3200K DDR4My Geekbench scores are a bit lower than yours (6290/34014) on 10.4.5, but my memory is only 2666Mhz...
What's your memory speed and do you have any BIOS memory/CPU optimisation or overclock ?
I went ahead and got the MSR 0xE2 (CFG Lock) removed. I also removed KernelPM as well as PluginType flags in Clover Configurator. I followed that up with some testing and I did see a small performance jump using Geekbench, however, opening the same Logic Pro project brought my hack to a grinding halt as the 1st thread of the 1st core spiked way up and stayed there. I tried to restart and NVRAM reset at Clover boot to no avail. Where the load on that thread was manageable before, became unbearable now. I attributed that to PluginType flag removal. So I went back into Clover Config and put that flag back but left the KernelPM flag removed in there and all seems to be back to normal. Still, not much improvement from the original state in terms of performance.Procedure for modifying the firmware to unlock MSR 0xE2 (or CFG Lock) has been added, along with stern warnings.

Switching to AptioMemoryFix-64.efi with and without slide=0 results in boot failure (Couldn't allocate runtime area). Maybe a different build of AptioMemoryFix might work, but for now it's best to stay with OsxAptioFix2Drv-free2000.efi.
I've unlocked MSR 0xE2 on my system now. Revised benchmarks. However, these small differences might be due to other factors such as background jobs running in the system at the time.

Agreed. Updated the guide with Step 17 to verify the change, and modified Step 21 to keep PluginType checked on.... I attributed that to PluginType flag removal. So I went back into Clover Config and put that flag back but left the KernelPM flag removed in there and all seems to be back to normal. Still, not much improvement from the original state in terms of performance.
Hello @nadena, glad to hear about the successful build. If you change your system definition to iMac19,1 you will get a new serial number as well. It is possible use an existing non-iMac19,1 serial number, but that can create naming conflicts. For example, "About this Mac" and iCloud might report two different system types.Hello, first, thank you for the great guide of CaseySJ, I followed your guide and everything worked perfectly for me. Now, I just updated my machine, to 10.14.5, and I was going to change the definition to iMac19.1. My question is, if the purchased programs that are registered with the other definition that I have now, will they continue working or will I have problems with them? Will he have another serial number?
Sorry with my English I am using a translator.
Thank you very much for all your dedication and help to others.
I am very grateful to his work and to the help of everyone in the forum
Thank you for the kind words and really glad to see that the saga of frustration is finally over. Random reboots are intolerable, and as you've noted, this system is quite solid (@NoiseCoalition's problem notwithstanding).
Hopefully the LaCie Thunderbolt 3 external array will perform as expected should you decide to purchase it.
Enjoy the Greek elections! Focus on the work, not on the machine!
Do you remember which version of setup_var you used?
The first two return two Setup variables (one 5000+ bytes, the other just a few bytes) with the second one being followed by the warning error: offset is out of range.
The third version (setup_var_3) handles this issue by ignoring the variable that returns fewer bytes, and applies the change to the larger Setup variable.
Even on the Designare Z390, AptioMemoryFix tends to work until we install a PCIe card other than the GPU. For example, as soon as the Fenvi FV-T919 WiFi/BT card is installed, AptioMemoryFix fails, but OsxAptioFix2Drv-free2000 continues to work.
Do you have a WiFi/BT PCIe card installed in your system?
