AHCI Controller

post #1 of 7
Thread Starter 
Hey all. I've just got myself the Asus Crosshair IV Formula motherboard and have installed the latest "chipset" drivers from Asus' website. This included an SATA driver and now I have AMD SATA Controller where before I had Standard AHCI Controller, which I guess is Microsoft's driver. Is this ok or will TRIM no longer function?

I've confirmed through the Command Prompt that DisableDeleteNotify = 0 with the new AMD SATA Controller driver but I'm sceptical about this still being ok. What are you recommendations?
Should I roll-back this to Microsoft's driver?
If I do this, I guess I wouldn't lose SATA 6.0Gbps functionality, right?
My storage HDD is SATA 6.0Gbps, hence my concern.

Thanks!

I can't speak from personal experience but I have heard mixed reports about the AMD driver. Why don't you try it, run HD Tune and check performance. Then switch to msahci and test again. See which is best for your system

Thanks for the reply. I've now tested this and it seems with the AMD SATA Controller driver, I get about 10MB/s faster reading speed on the SSD. On the storage HDD, the speed is about the same with both drivers. I guess I'll stick to AMD's unless I notice a problem with extensive use later on.

1. Microsoft's driver supports TRIM.
2. SATA bandwidth is not dependant on drivers, so Microsoft's driver will also achieve 6Gb/s
3. AMD's driver should be more optimized for their hardware, so it might be a little faster then Microsoft's
3. DisableDeleteNotify is not useful and only reports 1 if you set it to 1
4. Reports have come out that AMD's latest SATA chipset drivers (from September onwards) support TRIM

I spent the last hour or so trying to get that AMD AHCI driver to stick but no go. Kept blue screening at the "Starting Windows" screen I did a secure erase earlier today and all went as planned. I tried both msahci and mv91xx drivers a couple of times each and found that the Marvell driver is still best for me on SATA 6GB/s

AMD driver won't work on Marvell hardware only AMD SB7xx and SB8xx chipsets
