Show us your SSD performance

There are 2 Intel AHCI sata controllers in there. But, even without them it will run good with the Microsoft sata controller, MSAHCI.

One was for his model, the other wasn't. Where would he get the MSAHCI?

Windows automatically loads it during the change to AHCI, when you boot after the registry changes and BIOS changes, those are the drivers it downloads.

The 4K read improved 6 times. The rest is so, so. What is not good is the 41ms access time. That is not normal. There must be a problem with the controller or a BIG problem with Trim. It should be around 0.1ms - but 41ms is 410 times worse. That is a lot worse than a HDD which is between 10 and 15ms.

You are still in IDE mode. Tell us what you did in following the tutorial. You did the registry edits then rebooted, on startup did you change the sata mode in bios to AHCI? When you booted back into windows, you should have seen windows loading drivers, then rebooted again. Is that what happened?

No, that's not what happened.

First, I forgot to change the registry.

So I just went back now and changed the registry setting to 0, then I rebooted into the BIOS. The BIOS change I made last time did not "stick". That is, the SATA controller setting went back to "Native-PCI". I figure that's because I hadn't made the registry change.

So I changed the SATA to "AHCI", pressed "Save & Exit" and restarted Windows. Windows did not load differently and did not force a restart. Just to be sure, I restarted Windows again myself.

Windows restarted and so I started AS SSD Benchmark again. It's running right now. The text pciide - BAD is still there, and it's still red.

Go back to the tutorial and do everything in order exactly like the tutorial says. It is really easy and you will be happy with the performance gains. It's just that the tutorial has to be followed step by step.

I think I did do it right the last time. I set the regedit key to 0; booted to the BIOS and changed the SATA Controller setting to AHCI; started Windows. Right? What am I missing?

It's up to you, but why not try it again. I've done it 3 or 4 times and it has worked every time. What you are doing is forcing Windows to load the AHCI drivers. Then when you reboot after loading drivers, you should be in AHCI mode. Maybe I mis-read what you said, but it just looked like it was in the wrong order.

OK. No luck, unfortunately. I set the regedit key to 0, saved and shutdown.

In the BIOS, the AHCI setting did not stick, so I set it again, saved and exited, but went straight into the BIOS. The AHCI setting still didn't stick.

So this time, I set the SATA controller to Compatibility, saved and shut down, and then went straight back into the BIOS. Compatibility mode stuck, so I changed the SATA again to ACHI, saved and shut down.

Then went straight into the BIOS again and saw that AHCI setting was retained. So I shutdown and tried to boot Windows. But Windows would not start.

Windows said there was a problem and it would only boot into Repair Mode. Repair mode ran for about 15 minutes and then said it could not find the problem.

I rebooted into BIOS and went back to Compatbility mode. I could no longer return to the original setting, Native-PCI.

I rebooted and Windows started normally. But when I start AS SSD Benchmark, it still shows pciiide - BAD in red.

I'm looking for more advice at this point. Any ideas what's wrong?

Thanks.

So what is the consensus? Should I try to upgrade my drivers or not?

It is always good to have updated drivers. But, I really don't understand the problem you are having. But, you can use Microsoft's AHCI driver or Intel's AHCI driver.It will work very well either eay. Microsofts drivers are provided by the OS. The registry edits and changing bios is what is supposed to make those drivers load. Microsoft's drivers (MSAHCI) will do well. I ran my SSD with them for about a year and was very happy with it. If I understand the problem correctly, it appears the problem is in your bios. The issue seems to be you setting AHCI in bios and bios not saving the settings. The honest answer is I really don't know. Bios should save whatever settings you change if you save and exit after making them.
