Hello, I'm trying to overclock my new pc but since I'm new to OC I would like to have some feedback about results and if what I'm doing is wright.
Intel 9700k with aorus z390 ultra
That's the complete build: https://it.pcpartpicker.com/b/T4V6Mp
I read some guides and I started with a slight overclock (4.7-4.8 GHz); anyway I don't want to push it at much more higher values in order to keep temperature and noise lower.
-Test1:
cpu Vcore 1.25V, cpu clock ratio 47, AVX offset AUTO, core current mimit 255, XMP active, undercore ratio 45, cpu Vcore loadline calibration TURBO, cpu internal loadline AUTO,
I DISABLED: Enhanced multi-core performance, Intel Turbo boost technology, cpu flex ratio override, intel speed shift technology, C1-C3-C6/7-C8-C10 state support, SVID offset
(pased 30 min with prime95, maxT 66°C)

(in the following tests, all settings are the one of test1 excepts what listed below)
Test2: cpu Vcore 1.23V (passed 1h of realbench)
Test3: cpu Vcore 1.215V (passed 1h of realbench)

Test4: cpu Vcore 1.215V, cpu Vcore loadline calibration HIGH, cpu clock ratio 48 (passed 1h of realbench)
Test5: cpu Vcore 1.205V, cpu clock ratio 48 (passed 45min of realbench)
Test6: cpu Vcore 1.215V, cpu clock ratio 48, AVX 0 (passed 2h of realbench)
Test7: cpu Vcore 1.210V, cpu clock ratio 48, AVX auto (passed 90min prime95)
Test8: cpu Vcore 1.200V, cpu clock ratio 48, AVX auto (passed 1h prime95)

I started having freezes during the bench if I set AVX to values different from 0 or auto with prime95 after approximatively 15min. I increase uncore to 46 the system crashes with both prime and realbench.
Even if at 1.200V the system seemed stable, during 3DMark bench it started crashing; increasing Vcore to 1.205 allowed to pass the bench.
In the latter cases temps are close to 57°C with realbench and 60-61°C with prime95.

Rusults are in the dropbox link. (I will update it after furter tests)

Any advices? temperatures are ok? there's something I should modify in BIOS settings?
intel speed shift technology, C1-C3-C6/7-C8-C10 state support should be kept deactivated?
For now I started with a lower OC, maybe further on I will increase it.
Thanks for the help
