ssd on amd setup question

[86waterpumper]

alright I hope someone can shed some light on this for me.

This weekend I am putting together a htpc system for the house. I have a 40gb owc mercury ssd boot drive for it. I am going to be using win7 64 bit, and I am clean installing, so I know it will setup trim and configure stuff pretty much as it ought. Where I have confusion is what to do on the achi driver. I know awhile back amd did not have a proper driver that would do trim, now I read where people say they do, but it runs slower than the win7 one? So what is best to do, just enable achi in the bios, load windows on the thing and use it? Or try to change out the driver once windows is loaded? Also does win7 turn off indexing and such by default with ssds now or not? I have noticed in the past that if you manually disable indexing in win7 you lose the search features too which kind of sucks. Thanks in advance for the help!

1) Setup AHCI mode in BIOS
2) Install Windows 7 on your SSD
3) you now have TRIM

But the older AMD drivers did not feature TRIM; you had to use the Microsoft one. Microsoft should be installed by default. If you install chipset drivers, you install the AMD driver. This could mean loss of TRIM; so be careful. Only the most recent AMD drivers support TRIM, and only when the SSD is not part of a RAID array (though the BIOS setting could be either AHCI or RAID).

Thanks for the help. I am scoring a 7.7 on windows experience index already so I guess I will leave things as they are with the default microsoft driver!

The newest AMD AHCI(11.2) driver has TRIM, and for me is a bit quicker in random I/O than the Microsoft AHCI driver and did speed boot-up by a few seconds.
For Indexing, you don't have to turn it off and it doesn't happen by default. The only thing that gets turned off is Defrag, and that should only apply to the SSD and not the HDD that might also be in the system. This means the Defrag Service will still be on, but Windows will not allow it to run.

thanks for the tip! Do I need to also install the southbridge and raid drivers for it to work properly or just the ahci?

You are right, defrag is enabled, but not for the ssd, but prefetch, and indexing were indeed left running and I left that be. I do plan to add a storage drive so good to know it will defrag. I noticed that defrag was enabled for a usb thumbdrive I had on the system lol what is up with that?

You don't have to install the southbridge drivers but it can't hurt. There is no need to get the RAID drivers when not using RAID.
