AMD motherboards and SSD TRIM

[Moffat Cafe]

According to most of what Ive read on the net is that an AMD motherboard, even with AHCI enabled, will not support TRIM!! Is this true?
By the way, my motherboard is a Gigabyte 785GMT-USB3.

I think the issue is if you install the AMD drivers, rather than the MS drivers. There have been a number of issues with the AMD AHCI drivers. Originally, they didn't support TRIM, but I cannot imagine that to still be true.

MS's built-in drivers for IDE and AHCI mode both support TRIM in Win7.

Not sure where you read that, but I'm not aware of any issues with AMD motherboards and TRIM. Should work regardless of motherboard chipset as long as your SSD and OS support the TRIM command.

this thread should probably not be in the video card section. And i think AMD boards support trim just fine but im not 100%

In AHCI mode, the HD monitor did not find my SSD.
Maybe IDE mode will, need to check it out.

Its a driver thing. AHCI will not find your drive. Just leave it at IDE or RAID mode. With IDE it will find the drive. AHCI gives problems. I tried changing it once to AHCI for the hell of it and my eSATA external did not get recognized.. soo stay clear from AHCI dont use it. gl

Use the built-in drivers instead of AMD's then I guess? SSD performance is crap in IDE or RAID mode, if OP is running one it really should be in AHCI. Using the Microsoft drivers I haven't had any problems with AHCI or TRIM in Windows 7. It might be more of a crapshoot in older OS like XP, though (really if you're using cutting edge hardware like SSDs you shouldn't still be on such an antiquated OS, it just doesn't do your hardware justice).

Whatever chipset you have, TRIM should be supported if its a normal SATA/IDE port running in IDE or AHCI mode.

The only crucial thing is that you need to run a DRIVER that supports TRIM, currently only the Microsoft IDE/AHCI and the Intel AHCI driver support TRIM; no other drivers do on Windows, to my knowledge, including the AMD chipset driver.

So do not install the AMD chipset driver, but instead use the Microsoft driver that come with your OS. To see what driver you are using, download AS SSD and look in the text that says "iastor" for intel driver and "msahci" or "pciide" for Microsoft driver.

You would want to run in AHCI mode, since this provides a boost to your SSD's random read performance.

If your OS install was done without AHCI turned on in the BIOS, you have to do a registry tweak in order for AHCI to work ..

Edit the registry at your own risk..

I will say I used this tip, and it worked for me ..
