    Z390-I Random reboots under load RMA?

    Hello everyone!

    I'm in need of some help, as I'm out of ideas.

    I'm having random reboots when under load (no blue screen, just a brief freeze, and a reboot).
    I can reproduce the issue easily when running Prime95 (small FFT), within 10 minutes it will reboot, also when gaming for more than an hour (tested various games).
    A workaround that I found in order to be able to play some games is disabling the CPU turbo, hasn't rebooted yet while gaming with turbo disabled, but it will reboot in Prime95 even with turbo disabled, although it takes longer to do so.

    Specs:

    MB: Asus Strix Z390-I
    PSU: Corsair RM850x Part Number CP-9020156-NA
    RAM: Patriot DDR4 3200 Part Number PVR416G320C6KW
    CPU: Intel i9 9900K Part Number BX80684I99900K
    M2: Samsung 970 EVO PLUS 500GB Part Number MZ-V7S500B/AM
    M2: Samsung 860 EVO 1TB Part Number MZ-76E1T0B/AM
    SSD: Sandisk SSD PLUS 240GB Part Number SDSSDA-240G-G26
    SSD: Sandisk SSD PLUS 960GB Part Number SDSSDA-960GB-G26
    VGA: Asus Dual 2080 TI OC Part Number DUAL-RTX2080TI-O11G
    Cooler: NZXT Kraken X42 Part Number RL-KRX42-02

    Things I've tried:

    Changed PSU for known working 1000W CoolerMaster

    Changed CPU for another I9 9900K

    Tried 5 different sticks of ram, two different brands.

    Updated Bios

    Tried Prime95 on Ubuntu

    Tried without VGA, using onboard video

    Tried some different bios settings, XMP disabled, CPU current capability to 140%.

    Nothing helped.

    Let me know if there's any other info I can provide.

    Edit 1:

    Have you watched your temps as heat will make it reboot as well as dust inside the case will do the same?
    Bios 602
    passed 8hr test on Karhu RamTest
    Set to Manual OC
    Dram Frequency 4266MHz
    Dram voltage 1.45v
    CPU VCCIO Voltage 1.25v
    CPU System Agent Voltage 1.29v
    Dram timing control 17-18-18-38
    Mode1
    Dram command rate set to 2N set dram current capability to 130%

    Hi, Thank you for answering!

    My temps are very good, CPU maxes out at 70ish C in prime95 and after a few seconds running it will go down to around 65 C and will stay there.
    And during gaming it never even reaches 60C.

    The only detail is that I'm using an open chassis (Thermaltake P3) so there's not much airflow.
    Maybe the Z390-I VRM's can't take the load from an I9 without airflow?

    Should not be as your temps are good but to just test any way to remove the side of the box and blow air in from a fan. Or if you can set fans to run on high or extreme speed? Other then this have you tested PC with no xmp at all / no oc at all just default bios?

    I did try pointing a 120mm fan straight at the VRM's but it didn't work, I don't know if that's equivalent to a case with good airflow.
    It reboots with no overclocking, even reboots with the turbo disabled @3600 MHZ on all cores, I have never attempted to overclock.

    And I did try with XMP and default bios, but it sitll reboots, the only thing that seems to make a difference is disabling turbo, but all that accomplishes is to delay the reboots.

    I'm out of ideas

    Thanks for helping!

    What bios are you on? When I was on bios 805 I had nothing but issues I had to go to bios 602 to get my rig stable so if not tried then try bios 602.

    Hi Phillyflyer,
    Thanks for helping.

    Unfortunately, I flashed to 2401, run prime95 and it froze and rebooted in 7 minutes.
    Then Immediately after I changed CPU Load-line Calibration to LEVEL 3 (was on LEVEL 2) and when I ran prime95 it froze and rebooted almost immediately.

    Bump LLC to 5 and set Dram Current Capability to 130% if u have that feature in the bios.
