barry2811 Posted December 17, 2010 Share Posted December 17, 2010 Got a new motherboard with a new southbridge on it. Should I use the AMD driver or stay safe and use the Microsoft one? There was some talk that the AMD 10.11 drivers added TRIM support but I can't see it in the 10.12 drivers. Link to comment Share on other sites More sharing options...

Synbios Posted December 17, 2010 Share Posted December 17, 2010 Personally I would use the microsoft one as I have always had advertised speed with them and no stability problems. I never even bothered to try the Intel drivers because of my lack of problems. It's really up to your preference, but most likely there is minimal impact. I would try both and report back which you like better, if there is any difference at all. Link to comment Share on other sites More sharing options...

See this for info (taken from another forum - can't link due to censoring); Quote Originally Posted by dm7000s View Post Btw, there is also a reference in the .inf file that trim is supported: .. [amd_xata_Service_AddReg] HKR, "Parameters","AmdXataTrimSupport",%REG_DWORD%, 1 HKR, "Parameters","AmdXataOptions",%REG_DWORD%, 1 .. The latest 10.12 AHCI driver does NOT have that line in the inf. Driver version is: DriverVer=11/04/2010,1.2.001.0269 The 10.11 driver also had a readme.rtf which referenced TRIM support being added. This reference has been removed from the 10.12 driver's readme.rtf. Link to comment Share on other sites More sharing options...

The Microsoft AHCI driver hogs the CPU though which is something I would rather avoid if the AMD driver supports TRIM. Anyone know how well Sandforce drives garbage collection performs? Is TRIM necessary with the Force series? Link to comment Share on other sites More sharing options...
blackops Posted December 20, 2010 Share Posted December 20, 2010 With the Microsoft driver and the same chipset my secondary drive would not show up after resume from sleep. The AMD AHCI driver fixed this problem for me. I too have the F60 as the boot drive. Link to comment Share on other sites More sharing options...

The AMD AHCI driver fixed this problem for me. I too have the F60 as the boot drive. I have this problem currently with my mechanical drives using the MS driver - I'm using an SB600 board at the minute - ready to swap to the SB850 with my new board at Christmas. Looks like I can have TRIM support using the MS driver but with greater CPU overhead and the sleep issue. Or I can use the AMD driver and probably lose TRIM and I'm not sure about the performance. Wish AMD would sort this mess out! Link to comment Share on other sites More sharing options...

barry2811 Posted December 20, 2010 Author Share Posted December 20, 2010 AMD AHCI Driver supports trim. That driver did, it looks like it was removed in the new drivers if you read my posts above. Link to comment Share on other sites More sharing options...

The new driver is from Decemeber 13 and the 10.12 package and it looks like it has been removed again, as per above posts. Link to comment Share on other sites More sharing options...
uscool Posted December 21, 2010 Share Posted December 21, 2010 Hi, I have sent a email to AMD asking if the new version got trim support so waiting for a reply, as im ordering a M4A89GTD PRO/USB3 board, so would like to know when i got it set up and what to choose Thanks Link to comment Share on other sites More sharing options...
uscool Posted December 22, 2010 Share Posted December 22, 2010 Hi, wanting to know of the driver 10.12 AHCI for Windows 7 supports Trim on SSD drives ? Thanks reply Thankyou for contacting AMD. Yes, our drivers do support TRIM, although TRIM operations have much more to do with the functioning of the operating system. In order to update this service request, please respond, leaving the service request reference intact.

Wired Posted December 23, 2010 Share Posted December 23, 2010 The reference to TRIM was probably removed from the 10.12 documentation because it wasn't a new feature to that version since it was added to 10.11. Link to comment Share on other sites More sharing options...

The documentation lists prior versions though - the entry for TRIM has been removed from there. Link to comment Share on other sites More sharing options...
PierreBr Posted December 23, 2010 Share Posted December 23, 2010 Just a quick question: I will be installing Corsair Force 60GB on an Asrock 780G motherboard and I'm wondering whether I should have a floppy with the AMD Ahci drivers or install it using the default Microsoft Ahci drivers and then update... ...that is, if the AMD drivers offer less cpu overhead and equal or better performance...

The AMD AHCI driver ONLY supports TRIM for SB8xx chipset or newer. http://www.hardwarecanucks.com/forum/450343-post35.html Link to comment Share on other sites More sharing options...
PierreBr Posted December 24, 2010 Share Posted December 24, 2010 Using this method to verify "fsutil behavior query disabledeletenotify", I get TRIM enabled with the latest AMD drivers and SB700 southbridge... CrystalDiskInfo also shows TRIM as enabled... Link to comment Share on other sites More sharing options...

Synbios Posted December 25, 2010 Share Posted December 25, 2010 Yes it shows as enabled but is it working? CrystalDiskInfo is not capable of showing you if TRIM is enabled or not. It only tells you if the DISK is capable of TRIM. Even if you had fsutil disabledeletenotify set to 1, it would still say the same thing. The only way to tell if TRIM is properly working, is to manually check its functionality. Link to comment Share on other sites More sharing options...
