I noticed my G751JY-WH71 (WX) has an M.2 port and wondered if the Samsung 950 M.2 worked well in this laptop as I heard it has problems in the G752

Works fine in the G752VY with native Windows drivers. I've seen only one post of it installed in a G751JY with a modified BIOS with poor results.
The G751JY does however fully support the SM951 M2 AHCI model with great performance.

Just watch the model numbers
MZHP=AHCI
MZVP=NVMe

Thank you, this is very helpful. Do you know why this one works better?

The G751JY does not support the NVMe protocol. This is still very new technology that just made its appearnace with ASUS ROG in the G752.

From ASUS G752VY propaganda page.

"ROG G752 utilizes the latest NVM Express (NVMe) SSD technology to give you blazing-fast data read and write speeds. Compared to Advanced Host Controller Interface (AHCI), NVMe not only maximizes sequential read and write speeds, but also minimizes random reading and writing latency. The result – faster system processes, and of course, faster gameplay."

As of now the M2 SM951 AHCI is not much behind the NVMe on this platform. I expect the NVMe performance to improve as the technology evolves and BIOS and drivers are tweaked.

The ASUS G751JY notebook uses the Intel HM87 Express Chipset which only supports PCI e Gen2 M.2 per Intel. I have the G751JY and upgraded my
256GB OEM Samsung XP941 PCIe Gen2 (AHCI) M.2 SSD to the larger, faster 512GB OEM Samsung SM951 PCIe Gen3 (AHCI) M.2 SSD and installed
a retail USB Flash Windows 10 64-bit on it. It runs much faster then the original 256GB Samsung XP941 did with OEM Windows 8.1 on it.
However, the speeds with the 512GB OEM Samsung SM951 PCIe (AHCI) are closer to the specs Samsung claims connected to a PCIe Gen2 Adapter of
1600 MB/s read 1350 MB/s write versus 2150 MB/s read 1500 MB/s write on a PCIe Gen3 Adapter. JustinThyme is correct though, go with the OEM
Samsung SM951 (AHCI) M.2 SSD. Remember to use a USB Flash version of Windows for the OS install and make sure you have the latest BIOS.

I would probably just use the Samsung Magician tool to move everything over

Unfortunately if you go with the OEM SM951 PCIe (AHCI) M.2 SSD the Samsung Magician software will not work . Samsung designed the software to work solely with their retail (only) SSD's like the Samsung 950 Pro, 850 Pro, 850 Evo but it won't work with their non retail OEM SSD's. Use a USB Flash version of Windows it's really the only way. I tried cloning to the SM951 via an external BPlus PCIe M.2 SSD to USB 3.0 Adapter/enclosure using EaseUs Todo Backup Home 9.1 cloning tool with no luck. I wasted a whole day on trying to clone to SM951 for nothing. Had to do a USB Flash clean Windows install then install all ASUS Drivers and now it all runs great.

aww, that's so disappointing... I guess ill have to do a clean install if I do this. Thank you for the heads up
