    Post Dual M.2 on ROG MAXIMUS X HERO

    Hi All,

    Currently, have the following specifications.

    Corsair Obsidian 750D Airflow Edition, ROG Maximus X Hero DDR4, Intel Core i7-8700K 3.7Ghz, Corsair H115i Extreme Performance Liquid CPU cooler, GeForce GTX 1080Ti ROG Strix OC GDDR5X, Trident Z RGB 32GB (4x8GB) DDR4 RAM, 2 x Kingston 240GB HyperX 3K SSD, 1 x 2TB WD ext. SSD & Windows 10 64-Bit
    My two SSDs have good health but are currently getting on. I want to upgrade for multiple reasons. This MOBO allows dual M.2. (Samsung 970 Pro) to be bolted on without any performance issues? Presumably, both NVME will run at PCIe Gen 3x4?

    I would likely keep my SSDs, clean wipe them for GoPro footage and Downloads.

    Cheers,

    Everything you need to know is in your manual.

    From your motherboard manual

    Page x

    When the M.2_1 Socket 3 is operating in SATA mode, SATA port 1 will be disabled. (top M.2 slot)
    When the M.2_2 Socket 3 is operating in PCIEX4 mode, SATA port 5, 6 will be disabled (Bottom M.2) slot

    When socket M.2_1 is occupied with a sata device, you'll loose sata 1. Which is not the case for you
    When socket M.2_2 is operating in PCIEX4 (aka the maximum you can set and that 970 Pro can use), you will LOSE SATA ports 5 & 6 (the 2 ports above each other closest to the bottom of the board) . If you set it to PCIEX2, you should not lose the sata ports, but the 970 will only operate at half its maximum speed. Most likely this is because the bottom socket shares bandwith lanes with those 2 sata ports.

    Evening,

    I only need two SATA Ports for 2x SSDs (Although I am not fussed if I don't use them anymore, as they were purchased in 2012.)

    I read the following on the website (Where the Manual is located) I read that both slots provided PCI-E 3.0 x 4. So presumably this is the fastest way?

    Dual M.2 Socket 3 Type M

    ・ 1 x 2242~2280 (PCIe 3.0 x4 + SATA)
    ・ 1 x 2242~2280 (PCIe 3.0 x4)
    Does this mean without blowing myself or my MOBO up that I can run two SSDs of the same performance on my MOBO?

    In that case. You're pretty much set

    1. Hook the 2 SATA ssd's up to 2 of these SATA ports. 1-2-3-4 (avoid the bottom 2 ports SATA 5&6, closest to the bottom edge of the board, consult your manual if you have to)
    2. Install both nvme SSDs and boot up.
    3. Install the samsung magician software and launch it
    4. In Samsung Magician on the left go to: Drive details. Now on the right check "Interface" for both drives. The top one should by default say "PCIe Gen. 3 x 4" (max speed), the bottom one MIGHT say "PCI Gen. 3 x2" if the bios is not configured (or smart enough) to auto set the 2nd drive as x4 (this depends on the motheboard). In that case you may need to go into the bios to change that. (I think the relevant setting is under "advanced - pci storage devices" or something. If it's on auto and magician said it was x2, switch it to x4 for M.2_2 and boot up.
    5. If you needed to change the pci speed in bios, Open magician again and check if it's now reported as x4. If it is, install the samsung driver and reboot.

    All done. And yeah you can do that safely. Click my system specs above my avatar. Check the hardware i'm running It's not the exact same model, but my XI formula has 2 nvme drives running, 4 SATA hard drives and 3 optical drives. Simply stating hardware wise, your board is tiny compared to mine runs fine with much more hardware, so yours should run just as fine with a lot less

    PCIe Gen. 3 x4 is the fastest currently capable yes (though there now are certain boards / ssd's that run on PCIe Gen 4, the 970 Pro is NOT one of them )

    btw 1600W for that tiny system? You doing quantum computing with that thing? Even under full load (CPU or GPU) i barely hit 4-500W (and i got an 800W PSU ) Feel free to report back if it worked.
