I took out my HDD, put in my new SSD. I changed the setting in the bios to AHCI as instructed. I installed windows on it, then I have my HDD replugged in. SSD has hard disk boot priority over HDD and its loading the new windows, BUT its not "fast". It stays on "Loading Operating System" for 20 seconds.

On the Samsung Magician program it says:

AHCI Mode
Deactivated

And on the SATA Interface it says N/A.

Any idea of what I haven't set up properly?

I have a p55a-ud3 motherboard.

Thanks

Perhaps you've got the ssd connected to a non-intel chipset sata port and windows hasn't got necessary drivers loaded to run these in ahci mode. Or your motherboard may have other bios options to allow certain sata ports to run in IDE mode and your ssd is connected to one of these?
 
I don't know? Really confused.

I plugged it into a Sata 3 port on my motherboard.

The thing is, my dad found a few SATA cables as the SSD arrived without them. Is it possible that this cable is sufficient enough?

says SATA on one side, "Aslink" on the other.
 
A SATA cable is pretty much a SATA cable but try a different one if you wish.

It's a P55 motherboard so there are no Intel SATA 3 ports, those it does have are from a Marvell 9128 chip (poor).

Try using one of the Intel SATA 2 ports (the blue ones I think), your overall experience might improve.
 
I can't see it being the cable causing the AHCI problem TBH.

OK it looks like that motherboard has a load of sata2 ports provided by the intel southbridge, plus a couple of sata3 ports provided by a marvell chipset. My guess is that windows doesn't have the drivers needed to run these sata3 ports in ahci mode.

You could either go hunting for them, or connect the ssd to one of the intel sata2 ports. You'd lose data transfer speed but I doubt you'd notice it unless you ran benchmarks.

If you do want to try finding the ahci drivers for the marvell chipset on your motherboard then you'd also need to follow a guide on how to enable ahci mode without reinstalling windows.
 
sata3 on that board will be marvell controlled not intel

theres two options in the bios to set to ahci,one is for the intel ports and the other is for the marvell ports so make sure both are on ahci,then try with the marvell again,they might be slightly faster idk

be sure to flash to latest mb bios aswell first,

I'll have a look in a sec.
Can you tell me how to flash the mb bios? Never done it before.
 
download the bios file/extract it to usb stick and flash through qflash,point it to the bios file

qflash will be in the bios

if your using the sata3 marvell ports just use the drivers what windows installs,they will offer better reliability
 
I'll need to make sure I have all windows updates done then, then I'll flash the bios, then try again in the sata 3 port? Or flash first, do updates, then try?
