Please check my 14900k undervolting “performance”.

[Dimidragos]

Hello, I’m a newb and a fresh owner of a famous 14900k bought second hand from a trustful person still in warranty. I use it in a “strange” configuration for the moment, on an Asus Z690-A DDR4 mobo ( yes it’s not a mistake, ddr4 and don’t blame me for that, i plan to go ddr5 later), with a Asus Rog Ryujin Extreme 360 cooler and a GSkil 3600 cl16-16-16-36 B-die for the moment in XMP2.
A soon as i know will get it i start to read about it and i understand the degradation , oxidation and instability problems that chip occurs.
With my under average knowledge and equipment I don’t think about overclocking but I clearly consider undervolting for better stability and long life hopefully. Here it’s where I hope to get help from people with knowledge becouse i hope to achieve good as good as possible performance and to avoid mistakes undervolting this CPU.
What i did in Bios is next:
Disable Intel Boost
Enable Asus Advanced OC Profile
Auto - Let Bios Optimize
Sync all core 56x
LLC - lvl4 rec for OC
Unlimited ICCmax - Disable
CPU Core/Cache current limit max 400A
Long duration power limit 253
Short duration power limit 253
IA CEP - Disable
IA VR voltage limit 1450
Real time memory timing - Enebled
SVID voltage - Adaptive Mode
Offset mode sign - minus
Offset voltage - 0,105
VDM controller - disable
Undervolting protection - disable
XMP2
I think that’s all. Other values are on auto or bios default including VCore voltage ( that I don’t like)
My results you can see in pictures but i can’t resume here also:
Cinebench R23 score between 40500-40850
An average CPU temp of 71C with 77C max
An average CPU pack temp of 82 to 88C
VCore average 1,242 , min 1,217 , max 1,314
Core Power average 246w to 253 max
All performance core at 5.550mhz average
From my point of view the score are really good for a Ddr4 , the numbers are fine i can have room to goo up in performance maybe but i don’t know how.
I tried 57x and i think i am stable at -095 offsets but i noticed an Increase VCore at around 1.35 and i abandoned that idea. I also didn’t see any better score value on CinebenchR23 with 57x on
My questions :
1) It’s ok/safe what i did??
2) What can I do better??
3) How can I set manual VCore?
4) From what setting should i start when i begin the RAM overclocking?

In photo you see the value after 25minute of CinebenchR23 stres testing. I have tested it also on Intel burner, on OCCT, Aida64 and Intel XTU.

I’m sure it’s many people who can help, sad that nobody it is available. I’m still waiting….

Is this a bios/uefi profile you load up now and then or are you running this config 24/7?

Disabling Turbo boost is no longer recommended , for some time now do to advancements in on the fly voltage and frequency adapting.

I'm gunshy from the last thread....

1. Yes.
2. Enable boost so you get the clocks (if you haven't already)
3. Why would you want to do that? That will cause increased power use at idle (as it won't drop down when set manually)
4. Your choices are to increase speeds, or lower the timings. That said, to me, the time you take to do this and test, isn't worth the outcome (a couple of percent at best in some cases).

Hello, i run this configuration like 24/7 but all settings was done in Asus Bios where i unfortunately don’t see any turbo boost. I come from a 10900 where i was blessed with a really nice and strong CPU and where everything was more simple. It’s like I wake up in the morning with this 14900k and a lot of issues about degradation and other crazy stuff i can’t deal with. Then i must be fair and say that i don’t know what I’m doing with this 14900. I know only what i want, to run it safe and to get a good performance from that safe run. If you can give me more clues i appreciate!

Thanks for your answer. If i enable boos will not lead to higher volume and power to the cpu??
I want to work with timings mainly because. I already use the ram from 3600mhz to 4200mhz on 16-16-34 with stable sistem .

If your friend bought it new ppst-motigation and applied them (update bios to the latest version), then there is nothing to worry about. All you're doing now is putting a glass ceiling on your chip.... and for no reason if you're doing it because of the problems you read about.

Short answer is yes. Enabling boost will increase power use and likely noise.

Really, have it at stock and enjoy the chip. You have nothing to worry about thats under your control. If you/he bought it pre-mitigation, the extended warranty covers you, and again, there's nothing you can do at this point.
