Hi everybody,
In short, I Overclocked my 9900k to 5ghz, the vCore was at 1.32. While running prime95 (blend) within the first 5 minutes the pc suddenly shut down and rebooted back into windows, no blue screen, simply a reboot.
No surprise that it happened when the Blend test was at its "hot stage" (max 100c). Do you think something's wrong with my Mobo or PSU? or is it some kind of built in protection?
Later I tried running the same test with default bios settings and it did get to 100c but NO shutdowns, it throttled a little bit.. but kept running. And the interesting thing is that in "stock" mode the vCore was actually higher because it was on "Auto" setting in the bios.
(FWIW before I tried prime95 I ran Aida64 and OCCT large data set without any issues) It's maybe important to say that I didn't update the bios so its in version F4 (first version)
When I overclocked I didn't look at the VRM temperature when it shut down so I can't say if this was due to high VRM temp, but the VRM temps on this board are pretty good so I doubt this was the cause of the shutdown) But the LLC was at Turbo setting (seems to be equivalent to level 6 on other brands' mobos)
Now I am running at stock settings until I figured out what caused the shutdown. I don't want to damage my pc. This pc is perfectly new, I built it from all new parts just 2 months ago. My PSU is corsair RMx 1000 by the way.
If some of you have any experience with the Z390 master, can you please let me know what can cause this shutdown?
EDIT: I am starting to believe more and more that it's not a vCore issue. because I already got up to 1.37 vCore and still getting those reboots in prime95 when it's reaching the AVX part of the test (a few of minutes in)
It seems unlikely to me that I passed an hour in OCCT and Aida64 with only 1.3v but getting shutdowns in prime with freaking 1.37v! My LLC is at Turbo
Is there any current protection/temp protection or something like that in the bios that I'm maybe overlooking?
