question about ryzen/am4/mobo/ssd

have you connected the sata drive to sata0 sata1 ?
this is the direct connection to the ryzen cpu  and not the x370 chipset

sirtoby1337, are you using an M.2 socket - I assume?  If so which one.  Please use the latest Magician (as datonyb recommended) and check the temperatures in the SMART data (on main page below bytes written).  At the top will be a Celsius temperature and further down will be Temperature Sensor 1 and 2.  These are in degrees Kelvin in hex.  Convert sensor 2 to decimal and subtract 273.  This will be the Celsius temperature.  It runs about 10 degrees higher that the temperature at the top on my drives.  I asked Samsung technical support what all this meant and I was guaranteed that the drive had no temperature sensors.  The problem I am pursuing is that the drive throttles at 70 degrees Celsius.  I have purchased and mounted heat sinks on my drives.  Thanks and enjoy, John.

sirtoby1337, queue depth makes a huge difference in IOPS.  I am trying to figure out how to set it, but failing so far.  Other performance tests allow the user to specify queue depth for the test.  Perhaps you should try one.  Have you tried using Rapid Mode in Magician?  If not, please do.  Enjoy, John.

Enabled RAPID MODE and results are 3600MB read / 2900 write / and IOPS is worse now at around 40-45k again.

And Magician says this when enabling it too.

from magician
"under current system environment, some functions in magician CANNOT be run.
if multiple iterations of read and write are performed, RAPID mdoe may become inactive due to system internal errors on some of the AMD / AsMedia controller or driver."

But even tho i managed to get the IOPS up to 75k after forcing the AMD controller driver on both controllers the IOPS is still kinda unstable it jumps around between 45-75k so i pretty much only increased the max IOPS but its not stable there at all.

Here is a benchmark with crystaldiskmark showing im way off on the 4k Q32T1 read/write

I manually updated one of the IDE ATA/ATAPI controllers in device manager with the AMD chipset driver and then the other one i kinda forced to use the AMD chipset driver too since it kept using the microsoft one.

And it only improved the performance by 50% but not stable it go up and down... sometimes 55k and other times 75k.

The driver version is 1.2.1.402 and there is a 1.3.1.277 but i think thats for server or something but it makes performance worse.

Saw on another topic that 7901 is the x370 chipset and 43B5 is the CPU.
