You just moved an old OS tuned for Intel onto an AMD system. It's 99.99% req'd to do. Copy the data off one of the 850EVO to a spare HDD/SSD and install a fresh Windows. https://www.microsoft.com/en-gb/software-download/windows10 Use the above link to grab the media creation tool, put an 8GB of larger USB stick in, start the tool, and let it make a bootable 10 installation USB stick. That way you have the latest 10 release. I did this last night and after the install Windows Update took all of 5 mins. Also, install the latest 17.30 chipset drivers from AMD immediately after the OS is installed: http://support.amd.com/en-us/download <span id=DeltaPlaceHolderMain><div =supItem><div =grouper item medium>AMD Chipset, AHCI, USB 3.0 and RAID Drivers<ul =dfwp-list> <div =item>Windows 10??7 (32-bit |             64-bit?�​�ï¿??�​​​​​​​​​​​​​​​​​​�ï¿?/div> </span>[/QUOTE wrote: Well i just reinstalled w10 and secure erased the SSD with magician and yeah my SSDs are back to 100% performance.

Well i just reinstalled w10 and secure erased the SSD with magician and yeah my SSDs are back to 100% performance.

Too, IOPS, as a benchmark, isn't necessarily something to concern yourself with. You'll never realize that performance metric on a desktop machine. ie: you'll never max IOPS on a desktop, so, IMO, it's a waste of time. IMO. Transfer rates/throughput. That is what a desktop user should be looking.

No its not a fresh install, and they got around 150gb left each and both are 850 evo, and did try with just one on and same thing there, and its not just the IOPS that dropped, but i lost around 130mb on the 4k Q32T1 test in crystaldiskmark.

But do u think reinstalling W10 can solve this?, bcus everything worked just fine with my i7 4790k / gigabyte gaming 5 z97n, and wud suck if that doesnt solve it either, so wud rather try everything out that can maybe fix it before i try that.   

Guess nobody knows or got any other ideas how to fix this :s

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.

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
