(Spectre) Microsoft Intel Microcode Update - Confirmed the update


Recommended Posts

Just wanted to let you know I have confirmation that the Microsoft Intel Microcode Update works.

The issue I have a surface pro (2013) and custom built Sandry bridge system that bios updates ended years ago with no updates in site.

 

I used SiSoftware Sandra (lite) - https://www.sisoftware.co.uk/download-lite/ to determine the  current micro-code level.

Applied the update, and confirmed with  Sandre

 

Surface Pro (Info)

 

Before Update

 

Name : IVB (Ivy Bridge) Core v3 2C/4C 22nm 1.2-3.2GHz
Revision/Stepping : 3A / 9
Stepping Mask : E1/L1
Microcode : MU063A091C
Maximum Power : N/A - 17.000W - 21.250W

 

After update

 

Name : IVB (Ivy Bridge) Core v3 2C/4C 22nm 1.2-3.2GHz
Revision/Stepping : 3A / 9
Stepping Mask : E1/L1
Microcode : MU063A091F
Maximum Power : N/A - 17.000W - 21.250W

 

The updates below pretty much cover Sandy bridge (2xxx) to Coffee Lake (8xxx).

The only known issue, is depending on the cpu generation, certain types of cpu usage could be noticeable slower then before.

Note, this update does not cover the v4 variant just discovered, but may be included in a future revision of the update to include the code.

  • 4 weeks later...

there were other Intel Microcode updates from Microsoft for even older versions of Win10 that you missed, Eternal Tempest.

 

Microsoft support KB article 4093836 lists them all.

 

KB4091663 for Win10 v1703 - all editions (download here)

KB4091664 for Win10 v1607 - all editions (download here)

KB4091666 for Win10 RTM v1507 LTSB only (download here)

 

So far these updates do not cover Arrandale and Clarkdale (1st gen Intel core i3/i5/i7) processors yet, which may require a future revision of the updates.
