BIOS version 0607 is now out for Z370-E and most likely Z370-F and similar boards.
Notes: Improve system stability. (not really helpful but ok)
Please leave your feedback about this bios version here. So far it runs just as well as the 0606 for me, same overclock at same voltage. This BIOS version still don't change that I can't get my 3600 MHz 32GB memory kit to run stable above 3000MHz on this board - it's the F4-3600C16Q-32GTZR kit at https://www.gskill.com/en/product/f4-3600c16q-32gtzr
Hopefully this version includes improvements to the Spectre/Meltdown fix so the weird behavior from this is gone, some confirmation would be nice ASUS.
0606 cpuopt 300t m2fan 500t chassfan 1 500t chassfan 2 500t. 0607 cpuopt 300t m2fan 500t chassfan1 500t chassfan2 800t. to mutch fan noise go back to 0606. back to 0606 , chassfan2 still on 800t, it is an dcfan, i switched to pwm and click automatic fine tune, than i put it back on dc and now i can lower it to 500t, maby this works also with 0607 but it is fine for me, i had no issues with 0606, i am not an overclocker and have ddr4 2400.
The freezes and blue screens introduced in 0606 was also there for me in 0607. However, since I installed the Windows update I mentioned above I have had zero issues. All the update does is change a registry setting and that disables mitigation against Spectre, Variant 2 which was added to the microcode in 0606.
