Hey everyone

Help?

Just got a SM951 AHCI in the ASUS Hyper adapter card connected up to my GA-X79-UD3. Was able to browse the drive in Windows 10, and have cloned my HDD onto there using Macrium but now I've got to the point of disconnecting the HDD and booting from the M.2, it doesn't show in the UEFI BIOS.

The UD3 is on F20 BIOS which is the latest available.

Hoping there are some more things to try as I've got £150+ and 7 hours of my time invested in making this work!

What worked for me is enabling safe boot feature in BIOS
The boot mote also needs to be AHCI or RAID, the rest you can find in google.
If you could post some screenshots from BIOS settings, that would be great.

BIOS was set to AHCI and UEFI. Which screen in the BIOS would help - it's not the best BIOS for screen capping if I'm honest!

I've already gone out to a high street PC shop and bought a SATA SSD to boot from so I'm able to boot from a SSD. Would have been nice to be able to use the PCIe SSD to boot from but I don't think it's possible with this motherboard.

Hi,

I very recently bought a Samsung 950Pro 512GB with an Asus adapter and have it as the OS drive in my rig which has the Gigabyte X79-UP4 Rev 1.0 motherboard (F7 bios). I imagine this is not too dissimilar to yours.

After installing the 950Pro I booted off the original OS drive which was an Intel 520 SSD. I installed the Samsung driver to the 950Pro and then cloned my OS from the Intel SSD to the 950Pro using Aomei. After it rebooted I then took out the Intel SSD and changed the boot preference to UEFI first and the 950 second. I recall changing a few other options to do with UEFI and all was good. The CrystalDiskMark score is below.

I still have small problem though where on a cold boot it always boots into the Bios first? Restarts are no problem.

I can check and post exactly which bios entries I changed tomorrow if that helps?

Gigabyte boards have a habit of doing this :( - saving a profile makes its a bit easier if you use custom BIOS settings as it will reset them.

Usually it comes down to one of:

-The board doesn't entirely like the RAM you are using.
-Try using manual vcore setting instead of DVID offset.
-One of the connected USB devices throwing it.
 
hey thanks for the reply, I'ill give those a go.

I did read that it might be the CMOS battery which needs replacing?? but I initially dismissed, however I was going to pick up a battery this week(end)

Below are the changes I made to my bios and apart from the pesky cold boot issue it works well.

I did try changing Boot Option 1 to the Samsung 950 but it wouldn't post, it seems UEFI Hard Drive has to be Boot Option 1.

Hope this helps.


Bios Features

Boot Option 1 - UEFI: Hard Drive
Boot Option 2 - N1 Samsung 950 Pro
Hard Drive BBS Properties
Boot Option 1 - N1 Samsung 950 Pro
Fast Boot - Ultra Fast
Windows Features - Windows 8
CSM Support - Always
Boot Mode Selection - UEFI and Legacy
Storage Boot Option Control - UEFI First
other PCI Device ROM Priority - UEFO OpROM

Peripherals

Initial Display Output - (I selected PCIe3 as this is where my 980Ti is)
 
You say you havd the Samsung 950? That's NVMe?

Interesting looking at the specs our boards are very similar, but mine is up to F20 on BIOS versions. Looks like I chose the buggy one! Is yours on standard or modded BIOS?
