I have tried DS918 and DS3615.
First i have confirm the hardware limit. My cpu is i5-10400T, 12 theards , only DS3615 is OK.
Then I burn the 1.04b loader to usb driver but failed.
Other hardward
RAM: 8G*2 DDR4 2666
8T*4 WD HC320 hard drivers
512G M.2 Nvme SSD for cache
Motherboard NIC Realtek 8125
Pci-e NIC intel i210
After several failures on DSM6, I give up and use truenas instead.
Maybe I should consider using DSM7 because DSM is easy to use.
I read many many knowledge about the install, the possible reanson is the msi motherboard is not suitable.
