OK, I remember that RST ROM/OROM and driver version should be similar. At the moment, the latest firmware/ROM is 16.3, but the latest driver is 16.5 and I just re-downloaded the latest UBU 1.69.17, so there is no 16.5 firmware yet?

Because I am an absolutely, undeniably, factualy, consistently and constantly proven without possibility of doubt, the very example of a failure when it comes to complexities of figuring out UBU stuff. It was only due to nothing, but pure luck, that I have managed to not mess up any rigs with UBU :D.

I did read that thread and even though 16.5 ROM was available, it was not part of either of the latest UBU releases. UBU uses this format - RaidDriver.efi & SataOrom.bin and the downloadable 16.5 is just a BIN (custom number #) without EFI. Then again, I often fail to find exactly what I am looking for when it is staring right at me.

EDIT: Oh snap! The Intel EFI "Pure" stuff is the EFI file, but why is it labeled as a DRIVER and not firmware? See, that's a sure way to confuse people... And BTW, replacing UBU Final Sata and Raid RST module's 16.3 BIN and 16.3 EFI files with 16.5 files does not update UBU to show 16.5. It still shows 16.3.

EDIT 2: Oh snap x2! The 170b19 version did it for me, but to my defense - it is still a DEV version! Now I just have to figure out the mystery of new "iaStorSwExt.inf" extension files...

@Fernando,
I am surprise to discover the existence of Intel RAID controller v15.44.0.1010 driver version just after applied the last W10 RS4 cumulative update.
Is it normal ?
On this "Intel RST/RSTe Drivers" subforum I don't see this version listed. Is it a special Intel RAID controller driver installed by default ?

@Fernando
Thanks, reading the 2 start posts you refer I learn there are too much Intel divers variants to handle the Intel storage chip. I am sure the 'standard' user is lost.. and your recommended version is very helpful.
The lesson is it to the user to valid the optimal choice for its 'own' platform (if he does want the optimal performance).

Hello Fernando,

have here a new Intel NUC unit with VEN_8086&DEV_31E3 device. It's a June Canyon (Celeron Gemini Lake) set and I cannot find anywhere RST drivers for it.
Do you have any advice for me?

Hello again,

I Need advice for a new Server 2016 Intel Xeon machine I just built. I used a old Asus P5B Deluxe (LGA755 converted to LGA771) and it has a ICH8R IRST chipset. I used TWO SSD's in RAID for the OS install since I plan on using it for a Plex media server and I wanted the artwork and databases etc to be at their best performance. Everything is already up and running.

However, @Fernando says that it is extra dangerous to downgrade raid drivers from 11.5up down to Classical. Windows Server 2016 and Microsoft automatically install IRST v13.2.0.1022 (iaStorAV.sys).

Should I stick to what Microsoft Server installs (13.2), or should I downgrade to the Classical drivers? If the classical is better then why would Microsoft think otherwise?

EDIT: I also noticed that it is "iaStorAV.sys" not iaStorA.sys. Is iaStorAV.sys a special driver for older ICH on newer OS's?
Device ID is PCI\VEN_8086&DEV_2822&SUBSYS_81EC1043&REV_02

OK thanks @Fernando

So you think it is too risky to downgrade the drivers via Device Manager?
