i9 9900k whea uncorrectable error

[Ruddys]

Hi Guys.
Just a quick question.So I have been running my i9 9900k @4.9ghz 74c under 1hour of Real Bench for few months now.
But as summer is comming and for gaming I dont see much gain by overclocking I tought revert it all to stock and hopefully lover the voltage to keep the CPU under 50-50C Under load .

The thing is once I reset to defoult settings in BIOS and run RealBench in 3rd min I get whea uncorrectable error BSOD.
Issue pressists only when MCE is off or at auto when its enabled my CPU voltage goes higher than I would like.Disabled XMP as well and still getting the same BSOD?

Is there something I should know or this means that something has broken?

Usually means Vcore is too low. Either underclock further or raise voltage. 1hr of realbench isn't really a full stability test.

Just got suprized that Stock Bios settings are not stable at the 1st place.At 4.9ghz for my needs it was rock stable under long gaming sessions .

But thnaks for info
