Click to expand...

this bug or flaw found by Debian Linux developer

Problem: "Under complex micro-architectural conditions, short loops of less than 64 instructions that use AH, BH, CH or DH registers as well as their corresponding wider register (e.g. RAX, EAX or AX for AH) may cause unpredictable system behaviour. This can only happen when both logical processors on the same physical processor are active."

and this bug or flaw affect ALL operating systems ( windows , linux , etc... ) and it can also lead to data corruption or data loss , etc...

Oh that bug that was blown out of proportion because it affected big data sets?

cool that Asrock did it though. Props to them.

Or you can do what I did and mod your bios and upgrade the cpu microcodes your self.

No they didn't. The Micro-Code update was released by Intel back in May.

Of the 20 Z270 motherboards listed on MSI's website, only 15 have even received BIOSes with the Micro-Code update to fix the issue. And all the updated BIOSes were released within the last month.

Of the 20 Z170 motherboards listed on MSI's website, none have received a BIOS with the Micro-Code update.

Of the 22 H270/B250 motherboard listed on MSI's website, a whole 4 have received a BIOS with the update. Again, all the updated BIOSes have come out the past month as well.

You want to guess how many of the 35 H170/B150/H110 motherboards have an updated BIOS available? One...
