open the Command Prompt [Ed: run as administrator - Wired] and type

 

fsutil behavior query disabledeletenotify

 

Press Enter

you should see one of the following

 

DisableDeleteNotify = 1 (Windows TRIM commands are disabled)

DisableDeleteNotify = 0 (Windows TRIM commands are enabled)

 

If Trim is disabled then you need to go back to the Command Prompt and type

 

fsutil behavior set disabledeletenotify 0

 

Press Enter

 

If you ever need to disable Trim go to the Command Prompt and type

 

fsutil behavior set disabledeletenotify 1

 

Press Enter

It seems like the only AHCI SATA driver to support TRIM at this point is the default MS driver. The intel Matrix Storage, and Rapid Storage Drivers do not pass the TRIM function from the OS to the drives yet.

 

So even if you have it enabled in the OS and proper SSD firmware you may not get the benefits.

No and no.

 

As per one of the stickys (which leads to this MSDN article)

 

In Windows 7, if an SSD reports it supports the Trim attribute of the ATA protocol’s Data Set Management command, the NTFS file system will request the ATA driver to issue the new operation to the device when files are deleted and it is safe to erase the SSD pages backing the files. With this information, an SSD can plan to erase the relevant blocks opportunistically (and lazily) in the hope that subsequent writes will not require a blocking erase operation since erased pages are available for reuse.

 

The "sit and wait" is for garbage collection, which is different than TRIM.

Not so, superj,

ATI (AMD) also has their own AHCI SATA driver. It come with my DFI DVD.

Oh, and it supports TRIM according to post #4...

 

The AHCI driver from AMD doesn't support TRIM yet.

 

The only thing the fsutil query in post #4 does, is tell you whether the OS is sending the TRIM command or not. It does NOT tell you if the drive firmware supports TRIM, if the AHCI driver supports TRIM, or if TRIM is actually in effect.

 

You can try that fsutil query on a system that doesn't even have an SSD, and in some cases you'll be told that the TRIM command is sent. Does that mean that the system is taking advantage TRIM? Of course not.

so my GIGABYTE GA-MA770T-UD3P AM3 doesnt support the TRIM?

Your motherboard has no relevance. Every motherboard can run TRIM as long as it supports AHCI.

 

And as already pointed out, the only AHCI driver that currently supports the TRIM command is the one from Microsoft.
