Thanks in advance"

Good luck, I'm done...

My question was correct, you have just mis-interpreted it because you don't know how erasing a drive works.

"Formatting" on windows does *NOT* erase a drive, while ROG Secure Erase actually does.

This is a report of my problems with my new SM951 and Gigabyte motherboard.

I bought my new GA-Z170-HD3P to replace a five year old GA-Z68A-D3-B3.
The GA-Z68A-D3-B3 was working great, only the UEFI BIOS (U1B) wasn’t controlling the fans properly.

- My new system configuration:
- GA-Z170-HD3P rev 1.0 Bios F6d (beta)
- I5 6600K CPU
- 4+4 GB – G.Skill F4-3000C15
- SM951 – 128GB M.2 AHCI SSD drive.
- 2x 500GB HDD (WD5002AALX) on a RAID 0 array on ports 0 and 1.
- Thermaltake 450W high efficiency power supply.
- Graphics – Intel 530 internal graphics.

I’ve installed Windows 7 HP 64 with these BIOS configurations:
- SATA=RAID
- OS=Other
- Storage Boot and PCI device to UEFI only
- XHCI Hand off to disabled

Everything is working fine, except that when it enters “Sleep mode” it doesn’t wake up. The HDD led flashes continuously but it doesn’t wake up. Even the reset button doesn’t work. The only solution is to press the power button until it shuts down.

First test:
To find the problem, I’ve tested with these BIOS configurations:
- SATA=AHCI
- OS=Other
- Storage Boot and PCI device to UEFI only
- XHCI Hand off to disabled
- I’ve detached the two 500GB HDD RAID 0 array disks.

Booting Windows 7 HP or Lubuntu 16.04 64 from the SM951 AHCI M.2 drive, Windows 7 HP 64 and Lubuntu 16.04 64 recovered from sleep without problems.

Second test:
Next, I’ve detached the SM951 AHCI M.2 drive and the two 500GB HDD RAID 0 array disks and attached one blank WD 500G HDD.
With these BIOS configurations:
- SATA=RAID
- OS=Other
- Storage Boot and PCI device to UEFI only
- XHCI Hand off to disabled

In this WD 500G HDD I’ve installed:
- Windows 7 HP 64
- Windows 10 Pro 64
- Lubuntu 16.04 64
All them recovered from sleep mode without problem.
I’ve attached the two 500GB HDD RAID 0 array disks, and again, all them recovered from sleep mode without problem.
Then I’ve attached the SM951 AHCI M.2 drive and only Windows 10 Pro 64, sometimes, recovered from sleep mode without problem. Windows 7 HP 64 and Lubuntu 16.04 64 always failed to recover.
Something changed on the system that, only attaching the SM951 AHCI M.2 drive, Windows 7 HP 64 and Lubuntu 16.04 64 always failed to recover from sleep, even if they were booting from another drive.

Third test:
Next test I’ve done was with these BIOS configurations:
- SATA=AHCI
- OS=Other
- Storage Boot and PCI device to UEFI only
- XHCI Hand off to disabled
- I’ve detached the two 500GB HDD RAID 0 array disks.

Booted from the WD 500G HDD, and with the SM951 AHCI M.2 drive attached or not, Windows 7 HP 64, Windows 10 Pro 64 and Lubuntu 16.04 64 recovered from sleep without problems.

Summary:
- With SATA=AHCI and SM951 AHCI M.2 drive, Windows 7 HP 64 and Lubuntu 16.04 64 always recover from sleep, and Lubuntu 16.04 64 does boot from the SM951 AHCI M.2 drive
- With SATA=RAID and SM951 AHCI M.2 drive, Windows 7 HP 64 and Lubuntu 16.04 64 always failed to recover from sleep, even if they were booting from another drive and Lubuntu 16.04 64 doesn’t even boot from the SM951 AHCI M.2 drive.

Conclusion:
- SATA=RAID and SM951 AHCI M.2 drive have big issues and consequences.

I’ve searched and fond that this problem is very common on Skylake motherboards and that the manufactures are releasing BIOS updates to fix the problem, so I decided to install F6d (beta). It didn’t change anything to the sleep problem (and created a new one as the system freezes when trying to save or load a BIOS profile).

I’m very disappointed with my new GA-Z170-HD3P. The performance gain with the SM951 AHCI M.2 can’t be noticed when compared with my five year old GA-Z68A-D3-B3 system that has a Samsung 850 Pro SSD.
Boot times are the same and POST and shutting down are even longer.
I’ve asked for help at Gigabyte esupport and was frustrating. Those who answer the post, keep asking me things that was on my description and they are not technically prepared to even understand the problem.

Please don’t answer this post. Consider as a feedback to the engineers so they can release a new BIOS to fix this problems.

I had this problem with their x99 G1 Gaming and it turned out to be the SMbus driver that was sourced from Snappy driver installer, resolved...

There are many programs to Wipe a drive, that is, write 0 and 1 on it so it can't be unformatted and recovered. Aomei Partition Assistant does it.

All MB drivers are the latest from Gigabyte site. Where do I find the SMBus driver to fix the problem?

All needed drivers are supplied by gigabyte, no need to install any supplied by other sources.
I worked with Gigabyte over several days trying to resolve this problem, they could not duplicate the issue. After i figured out what it was, I can see why they could not find the problem.
This was a major issue and why I posted this response here, it was a real PITA.
BTW; My SM 951 is noticeably faster than my 850 EVO...

As I wrote on my post, the problem is when SATA=RAID and SM951 in attached, even if booted from another drive.
With SATA=AHCI I can boot Lubuntu and there is no problem recovering from sleep.
With SATA=RAID and SM951 detached, I can also boot Lubuntu and there is no problem recovering from sleep.

I've tested my SM951 CrystalDiskMark5 and the results are impressive. 1.5 times faster on write and 3.5 times faster on read, so I was expecting to have a much faster boot.
However, my boot time on SM951 takes, from pressing the power button to Skype log in, 41 seconds.
I've cloned my SM951 to the 850 PRO and boot time, from pressing the power button to Skype log in, it takes 42 seconds.
How to explain?
On a normal use, I didn't notice any difference between both.
I've already bought a new PNY CS1311-120GB to replace the SM951. Hope someday the issue with the SM951 and RAID gets set in order to work properly.

I was only making a statement about the noticeable speed difference between the 951 in M.2 and 850 evo Sata.
wakening from another OS kinda rules out the MB, don't you think?
Good luck...

I found this bad driver by reinstalling the op and testing after every driver install and creating a restore point until it showed up...

I’ve asked Intel for help. After a week exchanging posts, they said that “The SSD is not prepared for RAID, so random issues are expected”. In other words, the SM951 AHCI PCIe M.2 drive is incompatible with SATA=RAID.
What makes me angry is that the SM951 AHCI PCIe M.2 is on Gigabyte approved M.2 drives list.

Hello,

I created an account just for this; I have a problem with my SM951 512gb nvme that I have used for quite some time already.
No matter which driver I install, only the controller driver changes, the drive itself stays with the old Microsoft driver from 2006.
If the performances were there, it wouldn't be a problem, but right now it is horrible:


Any idea on how to deal with it?

Specs of the pc:
i7 5820k, Asus X99-A, 32gb Crucial DDR4, Palit GTX980TI

Edit: forget my post, I found what was causing this, I didn't check the "Turn off windows write-cache buffer flushing" - problem solved
