Samsung SM 951

[alphaev7]

Hi guys. My old Gigabyte GA-X58A-UD7 boots from Samsung SM951 without Bios mods/hacks! I have the 256Gb AHCI version installed in a PCIe slot trough Lycom DT120 adapter

The Bios (F9A) of course doesn't show up the M2 disk as a boot drive but Clover does. So I cloned my system on the M2 and installed Clover on another HD visible in the Bios, once Clover starts at bootscreen I can choose to boot from El Capitan on the SM951, no need to add custom entries or so, it boots automatically

Speed isn't as crazy as newer motherboards but I'm very pleased with this SSD on my old X58 motherboard.

Currently have a H87 + 4770 + 256GB Plextor SATA SSD on 10.10.5 Multibeast. Do you think i can get a Lycom + SM951 and boot up from the SM951? Interested as well.

Systems feels solid but could do with an SSD upgrade

You have to use Clover as bootloader.
If you start Clover from a drive that your Bios lists as bootable you should be able to choose the SM951 and boot....
BTW My SM951 is the AHCI version, I'm running Mac OS X 10.11.4

This version yes?

I'm thinking to upgrade to a 10.11 on the new drive as well. Just need to see if it will work with a Lycom + SM951 + Clover, seeing that booting from the NVME version seems iffy at this point.

That one should be even faster than mine (I have the 256Gb) so I should say go for it.

Hi guys, I own a SM951 with Skylake and Z170, and I'm having restart/shutdown troubles..Every time I restar it says "your computer restarted because of a problem". I've tried halt enabler, and fix shutdown, but still the same. Here is the log.

Any ideas?!

Hi guys, I own a SM951 with Skylake and Z170, and I'm having restart/shutdown troubles... Any ideas?!

Yes, this is a known bug of the NVMeGenerec.kext from MinnowStor, which does not occure, if u are using OS X 10.11.3 or lower. Above 10.11.3 the driver produces these kernel-panics even on restart or shutdown of the system. But the coder no longer works on this driver, because it never was planned or coded to be used as boot-drive.

So the community is waiting for someone, who is able to code a NVMe-driver with sourcecode being shared to the community.
Meanwhile we all have to deal with that annoying bug.

SM951/MZ-HPVxxx0 is M.2 PCIe 3.0 x4 AHCI. Works as an OS X boot drive natively on motherboards with the required slot (i.e., Maximus VII Impact). NVMeGenerec.kext supports SM951/MZ-VPVxxx0.

SM951 is M.2 PCIe 3.0 x4 AHCI. Works as an OS X boot drive natively on motherboards with the required slot (Maximus VII Impact). NVMeGenerec.kext does not support SM951.

SM 951 comes as both NVMe and AHCI versions.

Will my SM951 NVMe works OOB with my MSI Z170 Gaming Pro mobo? Shall I remove the NVMeGeneric.kext from my system?!. If not, is there any problem with this restart/shutdown trouble? I mean, can something be broken for this?
thanks

NVMe is going to cause trouble. The author never intended to use it as a boot drive.

Much better to get the SM951 AHCI.
