Samsung 850 pro Compatibility issues with Windows 10?

I have had a 850 pro for 4 months with no issues running that i can remember. After having Win 10 beta then going to the full upgrade my SSD drive decided it would want to act up. I would get random freezes, Samsung magician telling me the drive is now on sata 2 instead of sata 3...things like that.(Drive was set for ahci mode like it said to have it) Tried to see if there was a new firmware but it was updated to the latest one i believe when i first got it. Since then i have swapped back to my old regular hard drive. Ran memory/system tests and everything i could think of but the drive just doesn't function right most of the time. I can still run windows on it but there is a bottleneck for sure.

So just wondering does anyone think it could be an issue with the drive or maybe the firmware not being certified yet for Windows 10? I can't seem to get through the process of an RMA on the samsung website or find much info besides the firmware being flaky and pulled from the website. Just strange i would have issues with it now i guess. Not sure what to do or why samsung would atleast update there firmwares more often for a possible fix.

I was able to correct my Samsung 850 Pro from freezing up by turning off the ALPM setting in the Intel drive controller manager settings. Seems that the Samsung SSD's do not like that setting. Freezing was accompanied with the following Event Error in the system log:
The device, \Device\Ide\iaStor0, did not respond within the timeout period.

I'm not sure if this happens with other controllers but I thought I would share.

Only possible explanation would be Chipset drivers.

When i setup windows 10 i don't think i installed any of the older chipset drivers from the website. Do you think maybe if i reinstalled those Windows 8.1 drivers it would help? It is a Dell Alienware laptop btw.

I can't say that i heard of that before but, does this seem like the way to find out how to change it?

The one thing i should of done was check the system logs before i pulled the drive. Maybe i'll see about sticking the drive back in and trying it out.

I made the change using the Intel software but otherwise - yes, that's it! Once I made the change the freezing and lockups stopped. My guess is that Windows 10 switched the ALPM option back on. Hope it works for you like it did for me...

Before trying anything you did need to check in Event Viewer, errors still be there ? I have Samsung 850 not the pro no issues in Windows 10 and all Intel on mine, chipset and controllers, but best we have model and make check out all specs.

I really should of and can't say why i didn't check that before swapping the drives. You have the 850 EVO drive right? That's good though yours is still working for you, and may get that one if i can't figure this out. Once i get a chance to put the drive back in and reinstall Windows 10 i'll check the error logs again and post it back here.ty

Always check event viewer log, regardless it will still be there and as I would not attempt a fix based on another fix until you know for sure it is same as yours is.
