The MSI X470 Gaming Plus is unstable with the BIOS defaults. Worse the BIOS does not allow a user to change memory timings in a bid to use a different table to stabilise the machine.


The MSI Try It feature only works at DDR5-2400 and higher. There are no choices for the JEDEC speeds or latencies at all. Unfortunately some old DDR4 memory speeds are more limited.

There is a manual speed control and selecting DDR-1833 has been selected to attempt to eliminate the BSOD problems. That failed so DDR4-1600 is as fast as can be selected. So much for paying for DDR4-2400 memory.

AMD and MSI need to be aware that some users have older DDR4 sticks. The speeds are not as high bit the memory works as expected.

As it is now a user with BSOD problems is so common on the MSI forum that I have to consider that there are serious faults that need to be corrected.

The VIA based IEEE 1394a PCIe card does not seem to be recognized either. The card seems to have some thermal damage on the ASmedia 1083 chip while the VIA VT6703 seems to be fine. This leads to speculation there was a fault on the card causing the ASmedia chip to overheat. Replacement cards are under $10.


MSI has changed the BIOS on the X470, B450, X370 and B350. It had to be changed to accommodate all the new processors.

Now the basic text mode is offered to manage the operating system not unlike the old ways seem with the Windows 2000 and XP desktop machines. The larger disks pushed the PC to adopt UEFI which started to appear with Windows Vista Business and eventually this expanded into consumer systems.

The point and click class BIOS was an attempt to make it easier to handle the complexity of the moden UEFI BIOS.

The BIOS chip is 16MB so by removing the point and click the new ROM image is only 9.7MB so there is room for a large range of RAM and CPU choices. MSI has increased the BIOS size to 32MB with the X570 and they are introducing new MAX series X470, B450 and X370 motherboards which will also have 32MB BIOS chips. The move to 32MB was slow due to the cost of 32MB flash memory.

Bugs galore will take a long time to fix. So AMD and their respective board makers will have a lot on their plate.

There is presently no capability to tweak memory timing at all. The basic Try-it is all that is presently implemented. This means it is not possible to tune the memory to maximize performance.

DDR4-1600 seems to be stable. Anything fast seems to provoke BSOD faults. The RAM is rated DDR4-2400.


The X570 os still rotting away as the existing BIOS does not like my R5 2400G. Hopefully somebody can add more CPU and RAM sticks to the tables, this board has a 32MB BIOS with double the room. Obsoleting the R5 2400G after literally 8 months since I bought it doesn’t sit well either. I expect a CPU to be very durable and to have a practical service life of at least 10 years.


The Intel 9260 has failed and attempts to get it working have not been successful. A backup USB Wi-Fi adapter makes connections easy when needed. After replacing the card the error state was reset and the 9260 was operational. Evidently the BIOS faults are extensive. There are definitely problems that need correction and BSOD problems this X470 has presented have definitely been frustrating.


After a restart the dot appeared again which is incredibly puzzling as to the cause. The machine seems to be more stable after some adjustments to the components.


Swapping the 4GB and 8GB memory sticks seems to have stabilized the machine. Evidently this X470 machine is more sensitive to memory placement that others. The motherboard manual has an error showing the memory slots backwards from the actual positions.
