Asus Realbench -9900K-BSOD

[sew333]

Hello. Have an real pain in a.. with stability in Real Bench. Have 9900K oced to 5ghz. Ram: Gskill 2x8GB 3000MHZ XMP

Voltage 1.300v manual,Load Line 6 level,Sync cores 50,all power limits maxed.



So i dont know how to be sure if my system is stable. Sometimes after 15 minutes realbench throw BSOD.Sometimes it will pass 2 hours. So how i can be sure all is stable then? !!!!



One time it pass 2 hours fine in REALBENCH, i am thinking its fine. Next day after 15 min BSOD in REALBENCH.

mb:Asus Prime Z390-A, Noctua NH-D15


0x0000003b

SYSTEM_SERVICE_EXCEPTION

Its random.
Sometimes it pass 2 hours without problem,sometimes it not pass on the same voltage in REALBENCH. Any ideas? Maybe i should bump to 1.310v?

Temps 80-90C

Though i don't really have any experiences with Intel so far, with Load Line Level you mean Load Line Calibration? That sounds like what i have at my AMD platform, and there Level 6 seems a bit too high. Maybe it would help you to reduce that to Level 3 or 4. About the voltages and other settings around your Intel OC, i will leave that to other forum members with far more knowledge than me
Do you have an up-to-date windows currently?

Hi,

propably your Mainboard isnt capable of handling such high power demands. The 9900K @ 5GHz will draw lots of power, and the prime z390-a is a good board, buts its far away from being a high-end mainboard. So i believe its somehow overheating VRM´s. And maybe its random because of background activities wich will somehow pause the CPU.
Try to put a fan which blow direct on the VRM and if it runs longer or even stable you got your solution.

Windows 10 is up to date. Maybe should i try to bump voltage and retest few times?

In UEFI voltage prediction for AVX 5000MHZ is : 1.324V. Maybe listen to this and just enter 1.324V?

@sew333
Just test what Bully recommended. Have the VRMs cooled better than it currently is.
Bumping the voltage will only increase the powerdraw and the heating of the VRMs, which might result in an even more unstable system in that case.

i bumped voltage to 1.310 no crashing so its not vrm

Why are you asking for tips, and then ignoring what is recommended by the users and then just what you think to do?
I don't get it, because then you just don't have to ask here.

My i9-9900K runs at 5GHz with 1,22V and LLC 3. Maybe you got a bad CPU or use wrong
settings.
Maybe read the Overclocking Thread (https://www.computerbase.de/forum/threads/sammelthread-intel-overclocking-thread-teil-v.1485130/) first and I think your posting is in the wrong subforum.

On Asus Boards its so
LLC Level 1 = max LLC
LLC Level 8 or so = lowest LLC

So youre running much higher LLC which propably overboosting your voltage to similar 1,3x Volts.

At 100% laod the Voltage is 1,22V.
I have a negative offset of 0,025V as well
It runs at 5GHz 24 h with max temperatur of 75°C
I am using a MSI Z390 Gaming Edge AC Mainboard.
