Took out the hard disk drive and plugged back in the NVMe SSD into x4 PCIe slot and that booted fine too.

Started up the Mac Pro, gave it some time and it booted successfully into my Hard Disk Drive's Mojave with RAMs running at 1333MHz and the CPUs at 3.46GHz each. Put back all 48GB RAMs with 3 8GB RAMs on each CPU again. Took that out.ДЄs grant suggested below, took out all the RAMs and tried running with one 8GB RAM on each CPU (Mac Pro didn't boot at all).

I had a NVMe SSD plugged in to one of the PCIe x4 slots before the CPU upgrade and had Mojave installed on that too. I connected that drive with a docking station to a MacBook Pro running Catalina and run First Aid from Disk Utility on the drive. I had a rotating Hard Disk Drive which had Mojave installed and running fine before the CPU upgrade. I tightened the hex screws on each sink a tiny bit more (hand tight). I used an Air Duster on each CPU connector. Okay so the Mac Pro has booted successfully now and I have done a few things which any of them may have played a role or may have been the solution. I have the exact same problem as these two posts I have linked below. I have tried to boot into verbose mode but I get the End RandomSeed line and I can't type anything after that. My older CPUs also don't boot anymore, only these new lidded CPUs I got start up and get stuck at the apple logo. Right now the Mac Pro turns on, the only thing I can do is option boot (provided I have the ATI 5870 installed so I can see the boot options) and choose to either a High Sierra USB Installer or a Mojave Installer (both boot fine on other mac machines I have and followed Apple's guide to make a usb installer), but it goes back to Apple Logo and no progess bar and nothing happens after hours. I had another pair of delidded X5690 which didn't boot at all no matter what I did, so I returned them and got this lidded ones. I have also upgraded to a Sapphire Pulse RX580 and an older ATi Radeon HD 5870 handy. I recently got to X5690 Intel Xeon CPU's for my Mac Pro 4,1 (Upgraded to 5,1 with firmware update) and right before the upgrade I had a HDD with Mojave installed and also a NVMe with Mojave installed, and both used to boot and work properly.
