I needed a replacement for my existing Z420 Workstation. I moved the 32GB Ram to this PC and 4TB hard drive and TX 470 8GB graphics card. The fasted load time to windows login screen was 57 seconds. The slowest was 8 minutes. I don't know why there is inconsistency over booting times.
I installed a Zeon 2690 CPU into it and now I have a memory training error 3016 come up at startup.
I will get a PS/2 Keyboard as the system only recognises my USB Keyboard when it boots Windows 10. I found a online solution for the 3016 error is to make a change to the power settings in the BIOS. If that doesn't work, I will need to remove the processor and check for bent socket pins.
