Does 6.2 Fix the speedstep bug/Issue?

Hardware failure has forced me to upgrade, and this is where I have found Haswell and unRAID don't play nice together when it comes to SpeedStep.

With my Haswell CPU doing practically nothing it still wants to run at full speed, where my old Bloomfield was very happy to clock down.

The state show above is a SSH Session,Docker doing its thing and my kids watching a show.  No WebUI.

From what I have read it can sort of be adjusted with "intel_pstate=disable"

Info about that was found HERE

Has 6.2 address this issue or is the work around still required?

Thanks

I've been looking for ages for this fix! Thanks

(Sorry, I can't confirm if it's working on the 6.2 beta, not managed to get the beta running on my server yet haha)

Still trying to get an answer from the 6.2 thread.

I would try it, but they seem to be having some real issues right now, so 6.1.9 is the much safer place to be

6.2 doesn't fix the issue on Haswell. 

However, I can say that Skylake doesn't have the issue at all - everything works fine on both 6.1.9 and 6.2b21.  Well, 6.1.9 doesn't work with the i219V NIC that's run by the Z170 chipset, at least on my Gigabyte Z170N-wifi board.  I was able to use the i211AT no problems.

Is this just Haswell or Haswell-E as well? How did you get the information in the "code" section?

From a Linux terminal he did

cat /proc/cpuinfo | grep MHz

for the first section, and

top

for the second.

This does not effect Haswell-e, my 5930k does not have this issue.

My previous 4790s very much had this issue, and the intel_pstate=disable was the best way to "fix" it.

It is well known (from people with the issue, as others will tell you differently) that this is not a reporting issue, but a real issue with the CPU not properly throttling.

I confirmed this with both temp and wattage at the plug.

good to see this has not been forgotten, maybe with a little luck 6.2 buy the time it hits RC will have it resolved.

Currently running 6.2 RC3...

Speedstep still doesn't work correctly

I will have to re-add the pstate back into my config

Edit: On a Haswell Refresh Xeon 1231v3
