Question ThrottleStop 'EDP other' blinking in ring section with Intel 13gen ?

[gasolin]

Im getting red and sometimes yellow "EDP other" all the time in ThrottleStop.

Asrock B760 mb
13 gen intel,
Windows 11.

how do i fix it?

@gasolin
Intel has locked out CPU voltage control including IccMax adjustment on 12th and 13th Gen non K series CPUs. There is no way to fix EDP throttling unless you have an unlocked K series CPU.

Okay

But why does it happend ?

I couldn't live with that and that it only used 6 cores and 12 threads

I later found out is msconfig is limited to 12 processors (older cpu i had) you have to run without choosing the amount of processors, at that point i had returned ,send back my cpu.

How about 14 gen ?

When i disable turbo the ring edp other goes away

My 12100f has no problems at all with ring edp other limit, it's just not as fast as a 13400f

You can create a lot of problems if you change the motherboard or the CPU and you do not reinstall Windows. I always do a fresh install whenever making any major hardware changes.

Anytime the number of cores and threads is not being reported correctly in the Task Manager, the first thing to do is run msconfig and check to make sure the Number of processors box is not checked. This box should never be checked. Windows does not automatically update the number of cores and threads after a major hardware change. It is up to you to run msconfig and take care of this problem.

Most of the tech dudes working at places like Best Buy have probably never heard about this issue either. Now you know.

When you disable turbo, the ring runs slower, it consumes less power and it needs to flow less amps. That is why the EDP throttling problems goes away when turbo boost is disabled.

A slower CPU with fewer cores and threads needs less power and current to run at full speed. A slow CPU will have less reason or no reason to EDP throttle.

send back my cpu

Now you know that there was no reason to do that. Your CPU was fine. Windows was not setup correctly after installing your new CPU.

why does it happen?

Intel started using EDP ring throttling on many of their 12th Gen and newer non K series CPUs. This new trick forces the ring to run slower than the cache. Intel CPUs also use a feature called Ring Down Bin which is usually enabled by default. Ring Down Bin forces the ring to always run at least 300 MHz slower than the core.

At default settings, my 10th Gen 10850K also runs the ring slower than the core so Intel has been doing this for a while now. The default multiplier when all cores are active is 48 for the cores and only 43 for the ring. Setting IccMax to a low default value for the ring is a new technique that Intel is using but slowing down the ring is nothing new. It forces the ring to run slower than the core. This is done deliberately to improve stability.

With unlocked K series CPUs, the ring ratio is adjustable, the Ring Down Bin feature is adjustable and IccMax is adjustable for both the core and the cache. This lets a person run their CPU however they like. The 13400F that you were using is a locked processor. No FIVR adjustments of any kind are available when a CPU is locked.

How about 14 gen?

My best guess is that 14th Gen will be exactly the same as 12th or 13th Gen. The non K CPUs will continue to have locked IccMax. It will likely be set low and this will probably cause constant EDP ring throttling. Consider buying an unlocked 14600K. That should allow you to bypass EDP ring throttling as long as your B760 board does not lock out any FIVR adjustments.

I don't want a 125 watt tdp cpu

Just a 65 watt cpu with 6+ core and 12+ threads and run it at stock speed with increased power limit (didn't do much in power consumption and temps with a i 5 13400f but gave me more perfomance)

Now you know that there was no reason to do that. Your CPU was fine. Windows was not setup correctly after installing your new CPU.

How do i do that if i buy a 12600k or 12600kf (alot cheaper than a 13600k,kf)

If you buy a CPU with a 125W TDP rating, you can use ThrottleStop and limit it to whatever power level you like. The Intel power limits are fully adjustable, up or down. You can limit a 125W CPU to 65W if that makes you happy or you can do the opposite.

How do i do that

Always clear the msconfig Number of processors box after any hardware change.

I would like to avoid runnin g a cpu at less then what
it's rated at

You do know that TDP no longer means what it once did, right? It used to mean the worst-case thermal load a cooling system would have to manage, but after Intel got stuck on 14nm so long, they started using this to refer to the power consumption at base clock so it wouldn't look so bad in marketing materials vs. AMD. What used to be TDP is now called MTP (Maximum Turbo Power rating) and is the maximum power draw of the processor at full load.

The "125w" 12600k is rated 150w MTP
The "125w" 13600k is rated 181w MTP
The "125w" 13700k is rated 253w MTP
Your "65w" 13400f is rated 148w MTP. Not looking too different from 12600k despite the dramatic difference in TDP is there?

If you adjust the power limits to the TDP, then the processor will never Turbo. So the less charitable will consider Intel TDP to just be lies.

 

[gasolin]

I have a 12100f and it does indeed use no more than max short time power

it stays under 100 watt (doing aida64 stress test it used 40watt)

Since i get a litte ekstra performance from raising power limit (noise and power consumption is about the same og nor mre then 10-15 watt extra)

Max short time power isn't a problem

Ring to Core Ratio Offset should that be enabled or disabled ?

I have vcore offset in my asrock B760 mb but i don't seem to get it lower then -100, really ?

Can that be true, i have it at -100, using + or - i can get it higher but then it +, so limit is -100 ?

@gasolin
Some motherboards limit the amount of voltage adjustment available in the BIOS. After any adjustments to voltage, do some Cinebench testing.

Some B760 motherboards are enabling a new feature called Intel Undervolt Protection. This nasty feature can reduce Cinebench performance in half even if you only undervolt -5 mV.
