After using the BIOS flashback and assembling the machine with the MSI X570-A Pro motherboard the target platform is now complete. The MSI X470 Gaming Plus is now back in its original box. The MSI X470 Gaming Plus only was acquired because the R5 2400G was not being supported until AGESA 184.108.40.206 was released with support for the R3 2200G and R5 2400G.
The MSI X570-A Pro motherboard offers 4 available peripheral slots with PCIE-2 being disabled if PCIE-4 is in use. The machine is presently using a single video card and the Sapphire Nitro+ RX 480 is powerful enough.
The second major slot lacks enough bandwidth for some hardware contemplated. AMD sells the Threadripper for those who needs more PCIe slots etc. TR4 motherboards are double the cost of the X570 motherboards.
The BIOS on the X570 is double the size of the older motherboards. MSI had to remove their more advanced BIOS interface in older motherboards to be able to handle the larger AGESA modules. MSI introduced new boards with the larger BIOS chip but they have not surfaced at NewEgg yet.
The R5 2400 can handle a single video card which is practical. The Firewire card is used for HDTV based digital video. SDI cards need x8 slots so the MSI X570-A PRO is not suitable.
The back IO shield is comparatively basic. Given the number of USB 2.0 peripherals such as the keyboard, mouse and maybe a bluetooth radio or USB headset like the Microsoft LifeChat LX-3000, there is room for a more type A headers.
A rear bracket is available to bring the internal USB 2.0 ports to the rear but the HAF 932 has 4 USB 2.0 front panel ports. The limited USB 2.0 supply forces the need for internal hubs to provide more headers.
The focus has been more for the higher speed and higher power of USB 3.2 which can deliver power for charging mobile devices. Powered USB 3.0 hubs are available. Faster USB 3.1 or USB 3.2 hubs are widely available at higher price points.
A type-C to USB 3.0 type-A has surfaced which is an alternative solution. The front panel USB 3.0 box has a type-C port in addition to 3 type-A ports. Type-C hubs are also available, so more options are possible.
With only 2 USB 2.0 ports, the need for a powered hub is necessitated. Low cost powered USB type A hubs come with a power adapter to provide some power to the unit.
The SATA port multiplier is not generally needed with the MSI X570-A PRO unless there are multiple DVD/BD drives installed along with several hard disks.
According to the task manager startup. The X470 was about 24-27 seconds while the X570 is 16 seconds which is a big jump in performance. The overall boot speed seems to be proportionally faster as well.
Clearly the advantages of the X570-A PRO are well defined for professional use. Performance matters when demanding games are being played.
OVERVOLTING THE RAM
Due to problems galore with the RAM, I resorted to overvolting the RAM to the maximum safe level. It seems to have solved the BSOD problem which affords running the RAM at faster speeds.
No surprise that the standby feature does not work. Its is likely the BIOS bug list is lengthy which is typical with the new model motherboards.
A LOOK BACK
The old IBM System 360 model 25 was a 32-bit CPU and it had 32KB of core memory and it used punched cards to load software into the machine. Disk packs for the machine were 100MB but most shops used vacuum column table systems which were far less costly.
Now the rig has a 64-bit CPU, 24GB of memory and it has 16TB of storage installed. The rig now easily outperforms the old mainframe by more than 1 million times the performance.
