Asus z790 Gaming-F WiFi II

Hi,

Loaded optimised settings and enabled xmp1.

Cpu is new and Bios is updated to latest right away.

I'm using the Intel profile in the bios.

On my 14900k I can't see the frequency hit 6ghz? 5.7ghz is the highest I've seen on cinebence

I've tried single and multicore option in cinebence.

Cpu is cooled using ample cooling.

Single core i didn't see it peak above 40c

Can anyone please advise?

IMHO those 300MHz won't do any difference in real life workload scenarios. It basically applies to one or two threaded applications which are very rate these days.

And pushing CPU to 6.0 GHz will degrade it at much faster rate, since the VCore voltage would have to be push much higher.

Look up at google VminShift issue:

Here some example page.

ensure there is nothing running in the background. the single core boosts will always only appear there is like one program.

if cinebench is the only thing running (along with your monitoring software) then you should see your 6ghz clock speed

Do you know of a better way to check for the 6ghz boost?

So this is actually quite normal and something I'm experiencing that others are not?

Cooling wise I have a 4 rads and a core 1 cooler with Thermal Grizzly.

I checked and reapplied the application of thermal paste to ensure full even coverage using the spatualr spread method.

So temps are not playing a part.

Is there anything in the buos i need to be looking at other than selecting the intel profile & xmp1?

Would trying xmp2 possibly alter anything?

Although from what I can see on the corsair dominator 2 x 16gb sticks. Xmp2 was the same as xmp1 on the label.

I've now seen my 14900k occasionally hit 6ghz. Very short time. So is this how this processor works. Literally seldom boosts?

Almost everything today is multithreaded and not single threaded. Which is why you rarely get the boosts to 6ghz. But honestly it doesn’t make a difference as it will boost when it needs if an application will take advantage of it. 

dont listen to the other guy about degradation. They fixed that with the latest microcode 

Yes, the boost to 6GHz is for single core.
Practically useless unless you run very specific workload. A single threaded application or some static benchmark like CPU-Z or Cinebench.

Don't listen the other guy about that CPU degradation was fixed. It is hardware and desing problem. We don't really know if you have a CPU from new batch, and if it was ever fixed on newly produced CPUs.
Some were already on retail market.

Max Turbo Frequency 6 GHz
Intel® Thermal Velocity Boost Frequency 6 GHz
Intel® Turbo Boost Max Technology 3.0 Frequency ‡ 5.8 GHz
Performance-core Max Turbo Frequency 5.6 GHz

Max Turbo Frequency
Max Turbo Frequency is the maximum single-core frequency at which the processor is capable of operating using Intel® Turbo Boost Technology and, if present, Intel® Turbo Boost Max Technology 3.0 and Intel® Thermal Velocity Boost. Frequency is typically measured in gigahertz (GHz), or billion cycles per second.

Intel® Turbo Boost Max Technology 3.0 Frequency ‡
Intel® Turbo Boost Max Technology 3.0 identifies the best performing core(s) on a processor and provides increased performance on those cores through increasing frequency as needed by taking advantage of power and thermal headroom. Intel® Turbo Boost Max Technology 3.0 frequency is the clock frequency of the CPU when running in this mode.

Intel® Thermal Velocity Boost Frequency
Intel® Thermal Velocity Boost (Intel® TVB) is a feature that opportunistically and automatically increases clock frequency above single-core and multi-core Intel® Turbo Boost Technology frequencies based on how much the processor is operating below its maximum temperature and whether turbo power budget is available. The frequency gain and duration is dependent on the workload, capabilities of the processor and the processor cooling solution.

Performance-core Max Turbo Frequency
Maximum P-core turbo frequency derived from Intel® Turbo Boost Technology.

 

this is just plain wrong. the CPU requesting more voltage than what was safe was a microcode problem. not a hardware problem.

that is intels official statement on it if you want to check that out to brush up on your facts.

 

the fact was the CPU was requesting over 1.56-1.6v  during high or low load activity and that is what was causing the CPUs to age/degrade extremely fast. this was fixed. obviously if your cpu already degraded then nothing but an RMA will fix that.

 

stop spreading misinformation.

Is this normal?
