Hello Local Pro!
My present situation - very first time OC. Would you look at my BIOS settings screenshot and correct it please, what to do with CPU OC and in the end about DDR4 Crucial Ballistics opinions will be very welcomed and appreciated:
Didn't find how to attach screenshots here - My Bios album screenshots https://photos.app.goo.gl/hoQXznyRTvv1FgxQ8
a) clear some statements like: As Bulldozer said, important is only Voltage under loading!??
For example to set Fixed voltage as 1.4V for 51-52x and then with normal (High) LLC under loading it will drop till 1,28-1,3V and will be still ok for CPU and long life?
or better use 1.35V with Turbo LLC? Or it all depends on drops off amplitude up and down - turbo with 1.36V is ok but not with 1.4V?
My config now :
mb Gigabyte Vision G Z490
i9-10900K at 51x (48x cache) stable.
AIO NZXT 360mm
Main open questions:
a) CPU - I can't make it work at any voltages close to 1,25-1,3 as many reviewers-overclockers have. May they mean it after stress test drops by VR OUT?
For now I have setup: Fixed Vcore set = 1.380V (VR OUT in HwInfo shows 1.378V) LLС-level High or 1.35 with Turbo LLC !?
In CPUID = 1.380V and with Drop-off under loading in Cinebench20 - VR VOUT = going down till 1.289V and still working ok!
Same time if I set the same in Bios - can't load windows with 1.28-1.3V value in BIOS.
With stress tests- in Prime95 in SmallFFTs with Disable AVX2 was stable even with 1.35-1.36V only with TURBO LLC, what is it no good - because of Drops and returns amplituda too high for Turbo LLC?
Getting temperature in Cinebench20 with this Voltage till 94C :-( I have good enough working 9 Fan=6 in, 3 out middletower.)
Because of 1.380V?
Is it more proper check CPU with PRime95 SmallFFts NO AVX2?
Tried btw for a short period - 1.4V for 52x could be not enough to load windows and run stress-tests.

========================================================================================================================
b) I Have no idea how to set up a recommendation by everybody "Override Voltage" at Gigabyte (Adaptive too).
How am I supposed to use it after FIXED CORE for example 1.380V at 51x and High LLC?
c) So what are my options for 51-52x with fixed Voltage code, Override(Adaptive) Voltage.
PS. BTW Can't find SVID to switch it OFF as in ASUS mb instructions. Does it exist in Gigabyte mb?
PS2. CFG Lock OFF is ok?

PS. About OC DDR4 Crucial Ballistix:
DDR-4 2x16Gb Micron b-die Crucial Ballistix Game 3200 16-18-18-38 Standard XMPm now OC -> 3500 15-18-18-36 (trfc 560) with 1.39V.
TCMD = 1T and Trefi auto. (or 3600 18-18-18-38 but it is slower?).
Why slow memory test or is it a Gigabyte mb typical issue? After updates for some betas speeds fell down - from 40 to 30 Gb/s.
I read many reviews about good DDR4 OC but this is the max without errors in TestMem extreme profiles etc. VCCIO + VCCSA set till 1.3V nothing makes it stable.
And still in AIDa64 memory bandwidth are lower than in Cache-memory test around as 41-4-38 Gb/s and latency 63.3nc
Thank you for any answers and sorry so many questions to clear out.
