I believe you will have to enable RAID in the BIOS & perform a clean install. Pretty sure (almost positive) you need AHCI enabled for the SSD to perform satisfactorily. On this 435MT BIOS anyway.
Some operating systems, notably Windows Vista, Windows 7 and Windows 8, do not configure themselves to load the AHCI driver upon boot if the SATA-drive controller was not in AHCI mode at the time of installation. This can cause failure to boot, with an error message, if the SATA controller is later switched to AHCI mode. For this reason, Intel recommends changing the drive controller to AHCI or RAID before installing an operating system
After clean install make sure TRIM is enabled.
From CMD prompt:
fsutil behavior query disabledeletenotify
DisableDeleteNotify = 0 (Windows TRIM commands are enabled)
& defrag is turned off.
Since you have Win 10 there should be no issues with drivers. Win 10 should have all the latest.
Win 7 is so smart it enabled TRIM & turned defrag off automatically.
Thanks for your continuation.
fsutil behavior query disabledeletenotify returns a zero. So, TRIM is still enabled even after upgrading to Windows 10.
Now, I am wondering if I should do a clean install of Windows 7 or 10 on the SSD.
I will have to probably backup my entire HDD to another disk, just to be on the safer side and backup all my application data from C drive as well.
Then I am not sure how the activation of Windows will work, since I upgraded from Vista to 7 and then to 10 (all legitimate)
Maybe it is worth a shot to try and install Windows 10 and punch in the Windows 7 key if it prompts for it. This would be on the C drive (SSD) and without RAID array configuration, but just setting the BIOS into RAID mode.
Will see what the results are.
Yes make sure you have good backups, then can Clean install Windows 10 if you like.
Your copy of Windows 10 should have been registered on the Microsoft servers during the upgrade process & you won't have to worry about inputting a product key. I have yet to do this myself. That Windows 7 product key will not work to activate Windows 10. It will only be used if you install Windows 7 again.
Then as you said make sure BIOS in RAID & perform clean install.
I'll be doing the same in a few months
So, I decided to try a clean Windows 10 install on the same machine.
About product key: I had used a key finder tool to pull out the key in case Windows 10 asks for it. I also had my Windows 7 key handy with me.
None of the keys worked. Windows 10 got activated in the background transparently.
So, I put my BIOS in RAID mode and booted from my USB pen drive which had my Windows 10 installable files.
Installation took less than 30 minutes. During this, I got an option to upgrade or do a clean install. I chose clean install and formatted my SSD.
All went well and I was up and running. The sound problem was still there and the fix was the same as discussed in the other thread.
Now, Samsung Magician 4.6 is still the latest. I downloaded that and guess what: It still tells me AHCI mode is deactivated and it is unable to detect SATA interface details.
If I head over to Device Manager from Control Panel, I do see: Intel Desktop/Workstation/Server Express Chipset SATA RAID Controller.
So, I am guessing something is wrong with Samsung Magician.
Now the sad part is that for my 850 Evo SSD, sequential read and write values are below 285 (it is expected to be around 500).
Windows 10 reports: DisableDeleteNotify = 0
So, I am back to square one.
During the Windows 10 upgrade it should have registered your copy of Windows on the Microsoft servers. Doubt you can pull the Key using a key finder or more specifically be able activate Windows that way.
The two tenforum tutorials above explain a lot.
The XPS 435MT is a SATA II machine = 300 MB/s fastest possible.
Probably best to go to Samsung forum for info on Magician.
Before attempting another clean install you might try a Reset -look at this How to Reset Windows 10
I noticed that , it's a heck of a lot easier than doing a clean install the old fashioned way . I don't see why it would be any different .
