Corsair Dominator Platinum RAM kit (CMD128GX4M8B2800C14) reported as unknown manufacturer.
MSI GTX 1080 Seahawk X 8Gb GDDR5x (x2) reported as 4Gb of video RAM.
Samsung 950 Pro reported as SCSI device instead of M.2 SSD.
chances are Speccy is just showing the info it is getting from WMI.
for the Samsung issue for example, start an elevated command prompt, type in wmic and hit enter.
type in diskdrive get caption,model,pnpdeviceid,scsibus and hit enter.
that'll show the specific values for the Samsung, and just a diskdrive get will show everything.
for the RAM, memorychip get manufacturer will show you the stored value in the RAM's firmware.
and something like PATH Win32_VideoController WHERE "VideoProcessor LIKE '%MSI%'" GET for the video card should get some info.
