Installation of AMD AHCI driver

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   You have said the 17.10 "chipset driver" but have you checked or used the AMD "All in One" driver package? It's the same version provided with any ASRock AM4 board, so this link is just to the AM4 board I have:

It may be difficult finding the AHCI driver among all the files in this download. I am using RAID mode on my X370 board, so cannot tell you what AHCI driver I have installed, since I obviously have the RAID driver installed.

You seem to be looking for a Windows 10 AM4 AHCI driver for a particular reason. Might that be poor 4K random read and write speed performance on SSDs?

The Windows 10 storahci driver will be installed during the installation, but you should be able to manually update it in Device Manager.

I'm surprised the Magician software is not recommending the Microsoft storahci AHCI driver. It has been used since Windows 8, and seems to simply be a rename of the older msahci AHCI driver. In the past, the Magician software did not support the AMD AHCI driver until recently. Of course, AMD has multiple AHCI drivers for at least three different chipset now. That sounds like typical excuses from Samsung about problems with the Magician software.

	I've done a bit of further investigation. It seems that the 17.10 chipset driver does not include a windows 10 AHCI driver (this would be in a WT64A folder). There does appear to be a Windows 8 AHCI driver, but the use of this in recent versions of Windows 10 is reported to cause problems. Robert

	The default Windows 10 installation installs the Microsoft AHCI drivers. The most recent AMD chipset driver (17.10) includes AHCI drivers, but does not istall them. I have been able to install AHCI driver for one of the two AMD SATA controllers from Device manager, but am unable to do so for the other (I think it may be that the boot drive is on that controller). The current Samsung Magician SSD software will not provide certain functionality if the Microsoft drver is installed and recommends that vendor specific drivers be installed. I've been able to install AMD AHCI drivers on systems with SB950 chipsets, but could use suggestions here. I've avoided the all in 1 driver packages since I they tend not to be up to date. Thanks Robert
