I am an overclocker with i7-6850k, specifically I have it on an Asus
board with all six cores running at 4.3 Ghz and reliably at that. How do I
obtain this particular micorocode to test? The last one caused the CPU to
run at 3.6 Ghz with microcode installed so it is running without microcode
form Linux and just what Asus supplies.
Asus says this motherboard with i7-6850k is not susceptible to meltdown
and spectre but script says it is susceptible to the 2nd variant of meltdown.
