AHCI enabled but not really

[CDS Wambo]

hello, yesterday i was wondering if i have ahci enabled and then i went into bios to check, it says yes but in windows regedit in this section

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride

says i have the value on 3 when it should be 0 (according to the other post i read here) and i'm not sure to change it because i'm scared it will not boot

i have a boot ssd samsung 850 evo 250 gb with windows 10 installed from zero and a old DVD writer/ (maybe this could be the cause of that number?) and a 1tb HDD where i keep my games

Don't worry, it's not a problem to change that value to 0.

It seems like you already know how, but just in case you lost the link:

EDIT: saying "not a problem" is not totally true.
If you change the way your boot drive is accessed, you may not be able to boot, which is a problem.
Unless you have a real problem with AHCI being off, rather just leave it the way it is.

If AHCI is enabled in the BIOS and your system boots, then Windows is using it. It may not be using the default MS AHCI driver, though - you may have the Intel/AMD driver installed instead.

Where can I see if i have some of these drivers installed?

Update 18/05/2017 6:30 p.m.

I forgot to say sometimes when i turn on the pc it slow down extremely and almost freezes up and i have to restart the pc through the restart button on the case.
It's so annoying and frustrating and i don't know how to fix it. I don't have fast boot mode enabled in bios

Hello? Someone help please

Oops, sorry! Forgot all about this thread!

You can check what driver is being used by opening Device Manager and looking under "IDE ATA/ATAPI controllers". I see a "Standard SATA AHCI Controller" on my Win10 virtual machine, which indicates that I am running the default Microsoft AHCI driver. On older systems, there may also be a PCI IDE controller if the system has one or more parallel ATA ("IDE") connectors. (I seem to recall other manufacturers' AHCI drivers sometimes being listed under "SCSI controllers" or "Storage controllers" instead of "IDE controllers", at least on WinXP or Win7. I don't know if this still happens on Win10.)

On the extreme slowness, it might be worth checking the SMART status of the drives (especially the hard drive) using something like CrystalDiskInfo. If the hard drive is becoming unreliable, it may be making the system wait for long periods while it attempts to read data. Other than that, try the usual things like disk cleanup and removing stuff you don't use any more. If (and only if) the hard disk is healthy, you could give it a good defrag using a decent free defragmenter like MyDefrag (website seems to be dead but it is still available for download from places like Majorgeeks). Don't defrag the SSD, though - it'll do more harm than good.

CrystalDiskInfo says health status: "100% good" i guess its a good thing.

2 days ago i did an update to bios motherboard and the extreme slowness seems fixed, *Fingers Crossed*.

I have to wait some more days to see if it is really fixed
