The instability problems with the 13th and 14th generation Core i systems are a real thorn in Intel’s side. Since this problem became known, there have been several patches, one correcting the eTVB, and another correcting another problem. Now the company is speaking out again to announce a third patch to correct yet another problem!
0x12B: third patch for Intel instabilities!
Since the problem became known, Intel has identified three causes leading to instabilities in 13th-14th generation Core i systems:
- Motherboard power settings set beyond Intel’s recommendations. In this case, Intel recommends using the default profile.
- The eTVB, which allowed the CPU to run at higher states when the temperature became high. This problem was corrected by patch 0x125 in June.
- The SVID algorithm, which required high voltages at given frequencies and over given durations, which could lead to an increase in Vmin. This problem was corrected by patch 0x129 in August.
Now we learn that Intel has identified a fourth cause, this time linked to the bios/firmware. It would appear that during periods of low activity or idle, high voltages are requested by the bios. Eventually, this inevitably leads to the Vmin shift problem we’re all familiar with. This will be corrected very shortly via the famous 0x12B patch. We have learned that the company is currently working with its partners to make the patch available to the public as soon as possible.
