How can a bios update fix CPU bugs ? I dont get it at all.
The BIOS update also contains a CPU microcode update which was provided by intel that addresses the issue. [/quotemsg]
You did not explain how.
If the fix means "do it again" for every Error , then this is not a fix and will lower the performance.
This is more "not freeze" and not a REAL FIX.
Intel should recall all the CPUs and release new ones .
why on earth Intel can get away with this?[/quotemsg]
Changes in the microcode alter the way the CPU functions and can and do resolve issues like this. A google search on the term "CPU microcode" will provide more info than I can provide here. Think of microcode as firmware for the CPU. Suffice to say, the issue is resolved as Skylake CPUs are now, with the new microcode update, able to process the same data that caused instability without errors or crashes. In other words the CPUs will now function correctly. The microcode is not a part of the BIOS though it is usually released along side a BIOS update and is written through the BIOS. This bug was very specific and was only triggered when forcing AVX instructions to be used in prime95 or any other workload that triggered the same instructions sets, in other words very, very few real world tasks. This is not the first time a microcode update has been used to patch a bug in a new CPU line and it will not be the last. Recalling an entire line of CPUs for what is in essence a firmware glitch would be a massive waste of time and resources.
I hope this clarifies things for you.
