    Angry Asus ROG G752VS OC windows 10 slow boot on 970PRO

    Hello everyone,

    The story:

    At first I had sm961 256GB which was fast enough ( I mean boot time was very short) but after 2 years of using it started slow booting of windows10 and when I checked the health status of ssd it was 96% and 13.5TB writes which is not so bad but despite of this I changed to 970pro (new) which has much more speed and endurance.



    The problem:

    My laptop Asus Rog G752VS OC Edition with 970pro 512gb boots very slowly (even shutdown/restart process is long) the time it needs to boot windows 10/11 is 23 seconds.

    I tried fresh install of windows 10/11 with different versions of OS,drivers,nvme drivers,bios (moded also),RAM modules and quantities (1 slot,2 slots,3 slots,4 slots) and also tried different nvme ssd models but with no luck.

    Also I did crystaldiskmark test and got the result 970pro provides at maximum speed.

    Checked with AIDA64 software as well and got maximum speed.Also when I checked pcie controller speeds it showed pcie 2.0 speed at x4 bandwidth which I don't know is current speed when I don't use it or maximum negotiated speed (maybe it's current speed because read/write test shows 3500MB/2300MB).

    I checked specs with hwinfo64 as well and got x4 8GT/s which is equal to PCIe 3.0 4x (4x985MB/s) that is the speed 970pro can transfer (laptop supports pcie3.0 x4 as well) at maximum load (PCIe 3.0 4x) but despite of this windows 10 boots very slowly.



    Also I have to mention that when I press power button the laptop turns on then off and then turns on again and starts booting .The whole process takes as a minimum 23 seconds to complete.


    My laptop specifications:

    Laptop-Asus Rog G752VS OC Edition

    I have G752VSK also. I have pair of Samsung 960s in Raid 0 though and my 48GB of memory is DDR4-2800 clocked at 1400.

    I'm guessing you have a problem with that modded BIOS. I would suggest replacing that BIOS with unmodded 305.

    Good Luck

    Hello,
    Thank you for your advice.
    I tried unmodded bios as well with different versions but nothing has changed.

    Tried on TUF z490plus got max speed on benchmarks but still slow but not as much as my laptop.
    Also tested 2 more 970pro ssds and got the same result.
