    (Running at a slower speed obviously hides the fault however, or at least makes it happen less frequently).
    Thank you. Have a good day.

        Test 8 [Random number sequence]

        Hello Everyone,

        Do you know why the error is on the list? The computer works normally when I drop the ram frequency to 2933 Mhz. When I upgrade to 3200 Mhz, I get blue screen errors and reboot errors.

        My computer features include:

        Ryzen 5 1600 12nm cpu

        GSKILL 8GB (1x8GB) RipjawsV Siyah DDR4 3200Mhz CL16 1.35V (F4-3200C16S-8GVKB)

        MSI B450M-A PRO MAX

        EVGA GeForce GTX1650 SUPER SC ULTRA GAMING 4GB GDDR6 128Bit

        Samsung SSD 850 EVO M.2 250GB

        Seagate 2.5" 1 TB Barracuda ST1000LM048 SATA 3.0 5400 RPM

        Xigmatek 650W psu

        I do not know english. I'm sorry.

        Bye.

        Test 13 [Hammer test] Warning
        Note: Your RAM may be vulnerable to high frequency row hammer bit flips. However the conditions needed to induce these errors occur only very rarely in normal PC usage, and so this should not be of concern to most users.
