Windows: How to get latest CPU microcode without modding the BIOS

btw is this ITA substitute if set to max 0.5ms?

I am not sure I understand the question. But you can get information about which application requested current timer resolution. Execute in elevated command prompt:

Code:

powercfg /energy /output "trace.html" /duration 30

- that will create file "trace.html" in the current folder, so you can simply execute

Code:

trace.html

and default browser will open it. You will see something like this:

Code:

Platform Timer Resolution: Platform Timer Resolution
The default platform timer resolution is 15.6 ms (15625000 ns) and should be used whenever the system is idle. If the timer resolution is increased, processor power management technologies may not be effective. The timer resolution may be increased due to multimedia playback or graphical animations.
Current Timer Resolution (100 ns units) 10000
Maximum Timer Period (100 ns units) 156250

Platform Timer Resolution:Outstanding Timer Request
A program or service has requested a timer resolution smaller than the platform maximum timer resolution.
Requested Period 10000
Requesting Process ID 7084
Requesting Process Path \Device\HarddiskVolume7\Program Files (x86)\Opera\55.0.2994.44\opera.exe

...

Platform Timer Resolution:Timer Request Stack
The stack of modules responsible for the lowest platform timer setting in this process.
Requested Period 10000
Requesting Process ID 7084
Requesting Process Path \Device\HarddiskVolume7\Program Files (x86)\Opera\55.0.2994.44\opera.exe
Calling Module Stack \Device\HarddiskVolume7\Windows\SysWOW64\ntdll.dll
\Device\HarddiskVolume7\Windows\SysWOW64\kernel32.dll
\Device\HarddiskVolume7\Program Files (x86)\Opera\55.0.2994.44\opera_browser.dll
\Device\HarddiskVolume7\Windows\SysWOW64\kernel32.dll
\Device\HarddiskVolume7\Windows\SysWOW64\ntdll.dll

 

I mean the timer you were talking few times, well this app can set to max instead of default windows - Usually 1ms..

 

Well, I have my own tool for that - https://forums.guru3d.com/threads/windows-timer-resolution-tool-in-form-of-system-service.376458/

But only one game in my library was cured from stuttering by setting maximum timer resolution. So I don`t need it permanently.

 

Seems the Windows updates for this have been updated again, should cover more CPU models now since it even popped up on Windows Update here.

 

Bit of weirdness going on for me on 1607. kb4346087 bundled version C6 for my skylake CPU but I now have a KB4091664 reverting it back to C2 (which is also loaded in my bios).

In ms update, KB4091664 states that it supersedes the 087 update. http://www.catalog.update.microsoft.com/search.aspx?q=4091664

I had RS5 installed in a bootable VHD for a couple of days and it was C2 there too. I had expected it to be bundled with the latest microcode.

So is MS exposing me to spectre 3a and 4 threats? :S

Guys, I got a stupid question for you, if my update history says I already installed KB4091664 on August 2nd, I should still upgrade this, right?

 

If your CPU is listed, then I guess yes would be the answer if you want the latest micro-code.
WU should update if you need it though, might take a week to get to you.

 

There was such KB with microcode updates which was updated after initial publishing. So yes, you should (either automatically or manually).

 

Thanks guys, yesterday when shutting down he queued the update automatically anyway before I could bother to download.

 

I've got the update pushed on my PC as well even though my CPU isn't even listed in the KB article. Seems like MS is just pushing it out for everyone now.

 

I just got it too, but I had to manually check, didn't auto update this morning.
I am on 3570k too.

 

I didn't feel comfortable doing it to be honest. The instructions look quite advanced for an average joe like me:
https://www.win-raid.com/t154f16-Tool-Guide-News-quot-UEFI-BIOS-Updater-quot-UBU.html

which is why I was hoping Microsoft would put the Lynfield microcode updates on Windows update. It doesn't seem like they want to though.

 

You can ask nice people in UBU thread to mod the BIOS of your motherboard for you.

 

just was reading this here:

source:
https://www.ngohq.com/intel-microcode-boot-loader.html

what do you think of this?
Also, who or what is "NGOHQ"?
Also, i didnt find it anywhere, would i be able to use this with my Q9550 CPU?

But other then that a good alternative for older systems..

No, thank you. I will prefer to modify BIOS or wait for WindowsUpdate KB with updated microcode.

 

ok, so its not good?
im just asking because your actually the one who knows this stuff

To switch from UEFI mode to legacy one and to boot from USB drive - no way. May be for some server which do boot once per year...
