Asus Realbench -9900K-BSOD

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

If you are getting BSOD, even if it is only sometimes, it is not stable. Add voltage...not all 9900ks can do 5ghz @ 1.3v.

The "general consensus" for a computer to be considered reliable, is that its stable under load for 24 hours. If Real Bench crashes in 2 hours, the machine is not stable. If it crashes in 15 mins, its not stable. If it crashes in between 15 mins and 2 hours, its not stable. In the end though, you have to decide if its reliable enough for what you are doing. You could also try to narrow down what portion of the CPU is causing the crashes. Its entirely possible your CPU just needs more voltage. But, it may be specifically the memory controller, AVX instructions, cooling, etc..

No its BSoD.

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?

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

If it ever crashes, its not stable. If it never crashes at stock, the instability is overclocking-related. My advice would be to back the overclock down to 49x rather than increasing the voltage - 100MHz on 5GHz is 2%, and I would personally prefer the increased stability over that 2%.

The PRIME Z390-A is not a particularly high end board either, and might not be able to handle a 9900K@5GHz.

B.b.but muh 5 gigahertz!!! Lol most of those types would rather add voltage and wear than loose the epeen.

What are the temps doing, 5ghz bro?

Yeah for me it's 1.4V on air w/ 8700k. Sometimes if you want that 5ghz you gotta turn off those AVX loads. My guess if he's @ 1.325V is he's going to be seeing upper 70s/low 80s as peak temps in RB.

Typically 0x00000124 and 0x00000101 are the CPU voltage/temperature related BSODs. 0x0000003b I've only seen related to memory errors. It's a known thing that CPU frequency affects memory frequency stability.

So you might just need to increase the voltage on the IMC rail and/or Mmeory voltage.
