PRO Z690-A DDR4 + 13600KF Low clock

[ju-rek]

I have a problem with MSI Z690-A Pro motherboard with 1.92 bios. I have an i5 13600KF processor which, according to the specifications, has P-Core 5.1Ghz and E-core 3.8Ghz clocks. During testing with AVX or AVX2 programs, the P-Core clock is only 5.0Ghz, with the load of all cores. The problem is not the temperature (67 degrees). I was doing a factory reset and it's still the same. Is it the fault of the motherboard's bios, because such a problem does not occur on Asus boards.

On many motherboards AVX workloads have a -2 offset by default. That's my theory of what your seeing with lower clocks in AVX2 workloads. This can be changed to 0 but the option to do so isnt always clearly labeled.

Changing this parameter from "auto" to "0" does nothing, it's still the same. Apparently there is an "AVX optimum" option on Gigabyte discs, but I can't find out how it works.

Hmm. Well it says max turbo of 5.1 for the 13600KF with 180 TPD. You are peaking at 140 watts. My thinking is either the offset is still active, or maybe the P1= state is set to 140.

Im not a expert on this. But for example the 13900K I have has a max turbo of 5.8, but in heavy workloads it goes to 5.5. If I set a power target to 250, it will be even lower.

P1 and P2 limits are set to max. I wrote to MSI support let them speak.

I had an issue with my 13900K on my Z690 Strix and I updated the ME driver on windows and that did the trick. Try updating to the latest ME driver and see what that brings.

Is anyone running a 13900k with a STRIX Z690-E? (asus.com)

Scroll down the page and it should give you a link to update the driver.

Cheers.

It could be that as well. Drivers are a funny thing.

 

[ju-rek]

I had these drivers installed before. Nothing helped.
See what's going on.

It's at 12600KF 4.9/3.6Ghz

I will be installing my 13600kf maybe in a week... sorry I can't help right now, but I will try to figure it out next week if you still haven't figured yours out. Hope you get it sorted by then.

Will you have it on the MSI PRO Z690-A DDR4?

No, but I also will be running DDR4 and can tell you if I have the same experience or not. My guess is this may just be a normal experience? Have you seen any reviews where the all 5.1 is always sustained?

 

[ir_cow]

Honestly It looks normal to me after looking at all these screenshots again. Last one you posted has 1 core is at 5.1 turbo while the rest is 5Ghz or lower. That's how turbos work.

According to W1z, it should hold 5.1 under AVX on all cores.

This chart does not specify if it is referring to all core though from what I can see of the screenshot, it still might be referring to max a single core reached? Unsure, been awhile since I read the review. Human memory is a funny thing, sometimes I wonder, why do I bother reading at all, because I seem to forget within a week. lol

The cores/threads are at the bottom of the chart. The averages drop after 12 cores as the E-cores run at a lower clock speed affecting the average.

Until 12 threads (not cores). To me this seems like standard turbo The more threads you have the lower the clock turbo goes

The 13600k has 6 P-Cores with 12 threads. The remaining 8 are the 8 E-Cores. It's right in the graph, and in the review.

The E-Core side of this chart (threads 13 to 20) can be somewhat misleading. It looks like the cores run at increasingly slower frequencies as the load goes up, but that's not the case. The frequency plotted is the average of all the P-Cores active, plus more and more E-Cores, which all run at a lower frequency than the P-Cores, which drags down the average.

 

[Space Lynx]

The wording does make sense then, it is all core. Interesting.

 

[ir_cow]

The graph doesnt make sense. Unless the chart is saying that once the e-cores are active does the clocks drop

Any feedback from MSI? I have the same issue :/

 

[ju-rek]

They say everything is fine with them. They told me to test on a different board. they ignored it.

 

[ir_cow]

Max Turbo Frequency 5.10 GHz . You at 5.0 Ghz because of a AVX offset. Not sure why the 0 offset doesn't work. Try a newer BIOS?

 

[ju-rek]

On the newer 1.90 the same.

My issues is that even under AVX workload my 13600kf does not keep even 5.0 on all P-cores.

Power limits removed?
