    Hello guys. I'm not entirely sure if this is the right place to post my questions but long story short I want to swap out my HDD for an SSD but I don't know if it's compatible or not. If you're interested here's the link to my post * * *https://rog.asus.com/forum/showthrea...401#post616401 *I would highly appreciate it if you could check it out and give me your feedback. I'd prefer you replying on my post directly but here is good as well. Thank you for your time.

    Compatible 512GB AHCI M.2 SSD?

    I've been looking for a Samsung SM951 512GB AHCI SSD, but they are getting difficult to locate and the prices are getting out of hand. Are there any other options that might work? I would REALLY like a 1TB SSD, but would be happy just to find a good 512GB SSD at this point. This is to replace the 256GB SSD in the left-drive of a G751JY.

    Thank you,

    J

    We're in the same boat, Samsung no longer producing AHCI M.2 only NVMe M.2

    Out of curiosity I recently browsed a few retailers to look at the prices for the 512GB OEM Samsung SM951 PCIe AHCI M.2 SSD and like you state, they're getting harder to find, and the few that are for sale are now over $700 US which is nearly double what I paid for mine Dec. 31, 2015.
    Luckily I bought it when I did and upgraded my G751JYs original 256GB XP941 to the faster, larger capacity 512GB SM951PCIe AHCI M.2 SSD for only $365 US on Amazon US website via Platinum Micro. 7-8 months ago they were selling for around $329 US. What a difference a year makes, now Samsung is only producing the latest PCIe NVMe M.2 SSDs for OEMs & Retail market & no longer producing M.2 AHCI SSDs for OEMs
    (PCIe AHCI M.2 SSDs are end of life - legacy hardware, no SSD manufacturers produce them any longer).
    I found only 1 512GB OEM Samsung SM951 PCIe AHCI M.2 SSD on amazon.com US currently selling for $711 US (plus $4.60 shipping US only). The seller is Electronics World & they list only 1 in stock. Our G751JYs only support two OEM Samsung PCIe AHCI M.2 SSDs, the gen 2 OEM Samsung XP941(supported by all ASUS G751JY BIOS AS202 - AS211) & the gen 3 OEM Samsung SM951 (AHCI version only & provided you have ASUS G751JY BIOS AS206-AS211) as you already know. No other PCIe M.2 SSD brand or models are supported with our G751JY notebooks. If you're not planning on upgrading to a newer model, expensive, high end gaming/mobile desktop replacement notebook for another 2 years or longer and don't mind spending the $711 US, I'd go ahead and buy it if I were you. In a few more months they'll probably no longer be available for sale anywhere. Samsung will not be producing them for OEMs ever again. Our only other option is to bite the big one, spend thousands and upgrade to a brand new notebook that uses the upgradable PCIe NVMe M.2 SSDs. Then we can buy the newest, fastest, larger capacity, retail PCIe NVMe M.2 SSDs like the Samsung 960 Pro NVMe M.2 SSD 512GB $339 US/ 1TB $629 /2TB $1299 US or cheaper Samsung 960 Evo NVMe M.2 SSD or the higher priced, slower performing OCZ (Toshiba) RD400 NVMe M.2 SSD 512GB $279.99 / 1TB $704.99 on amazon.
    It's all about supply & demand and since we're stuck w/ only 2 OEM Samsung PCIe AHCI M.2 SSDs supported by our G751JYs that are no longer in production we're screwed! This is why I was hoping ASUS would provide owners of G751JY notebooks one last BIOS update w/ support for M.2 NVMe SSDs. I'm not sure if M.2 NVMe is supported by our G751JYs legacy Intel Broadwell CPUs & our legacy Intel HM87 express chipset on our mainboards, which is probably why ASUS hasn't provided owners of the G751JY notebooks a BIOS supporting M.2 NVMe SSDs? Lack of M.2 NVMe SSD support is one of the few things about the awesome ASUS ROG G751JY notebooks other than the drive bay 2 SATA 2 adapter that is too bad for us.

    Hi Jon G,

    Go check here : Win-Raid Forum

    Check in that post the "Clover-EFI Bootloader Method" too. That one doesn't require flashing bios.

    Just found this post too : G751JY-NVME-Support-950PRO

    I asked @Linux86 to share the bios with me. If it's really working will be able to use SM951 NVMe and SM961 NVMe (Will have to find out if this model can be used at full speed) . Will link on this post if i got the bios.

    SM951 (512GB) : Max sequential (MB/s) Read 2150 - Write 1500
    SM961 (512GB) : Max sequential (MB/s) Read 3200 - Write 1700

    Cheers.

    not sure if anyone still in this topic, but i managed to install MZVPV256HDGL in my Asus G751JT. Followed the Win Raid method.

    Reading 1700 MBPS / Writing 1300 MBPS.

    Pretty interesting mod.

    Can I simply swap the 128GB SSD for a Kingston Digital 480GB SSDNow V300 upgrade kit (using the kit included)? Thanks.

    ASUS G751-JY BIOS upgrade NVME / Win7 cloning to NVMe SSD

    Hello, I'm Christian from Germany. I have some good News for all ASUS G751 owners , that want to run a NVMe SSD on the M.2 Socket (must be built in already)
    Recently there was an Ebay Offer for a SM951 512GB NVMe PCIe SSD. I couldnt resist and bought it.
    Before, I already have a SM951 AHCI 512 GB HDGL-0001L (from Lenovo) which was running quiet good on my Win7.
    But unfortunately it runs only 1500 Read / 1200 Write (Specs are 2200 read/1500 write). I found out after some research, that the Lenovo SM951 has an inbuild limitation. Thats why I bought the SM951 512GB NVMe.
    And than the big hassle started..
    The new SM951 NVMe wasnt recognized by the BIOS. So I upgraded to BiosVer 211. Same Situation. No SSD recognized.
    Than i was reading about Implementing a DXE Driver Modul in Fernandos WinRaid Forum.
    I injected the DXE Driver in my BIOS and now my new NVMe SSD is recognized by the BIOS and is bootable as well.

    The hole BIOS upgrade is really simple, as long as you know what your doing.
    I will make a step by step Guide for the implementation in the coming days.
    Its really very simple, but it costs me some time to find out.

    After this I cloned my Win7 from the old AHCI SSD to the new NVMe SSD.
    Next Problem --> Bluescreen Fail 0000000x7B . Win7 doesnt provide any NVMe Drivers nativly.
    The clue is: Before Cloning, you must install a NVMe Controller Driver by Hand on the old Win7 running System . After installing the Driver
    you clone the System to your NVMe SSD and start. Voila--> Win7 running on SM951 512Gb NVMe

    And now after all: I realised I have the HM87 PCH that only provides PCIe Port 5 in Gen 2. --> no 2200 read
    The card itself does... but the Controller not... what the ****....
    Now I have same situation like before.. Maybe someone of you found out how to get the Controller (Lynx PCH Port 5 ) working in Gen 3.
    Answers appriciated.
    Now have speeds on the SM951 NVMe (1660 read / 1200 write) ... same like before

    Upgrade your G751 to support NVMe M.2 PCIe Drives

    I made a quick simple guide , how to upgrade your BIOS for NVMe Support. You really dont need to be afraid. My NVMe Drive works without problems,
    once the BIOS is upgraded.
    So there is not much profit in speed, because the HM87 Chipset can only support PCIe x4 Gen2 .. you will stay at 1600 MB/s read and 1400 MB/s write, but you dont need to pay a crazy amount of mony for buying a AHCI compliant PCIe SSD, that is even slower and older.
    Be smart and make BIOS Mod (update). If you have any questions, feel free to contect me ...
    Have fun:
