Hi rkraft

If you've updated to bios 1203 and updated windows 10 fall creators update, you're protected from Spectre and Meltdown.

You may download the tool 'InSpectre' to check the status of your install in Windows regarding the patch status from a webpage of your trust.

Bios 1203 contains the old 7C(80) microcode of the processor that Intel withdrew, if you did not know then I tell you this. bios 1203 seriously reduces productivity.
Currently the recommended version of the microcode processor 0x84 for Kaby Lake/Coffee Lake and 0xC2 for Skylake

So, in any case, Asus will update all his bios, they have no other choice.
I have already updated myself, it's much faster to do it yourself than wait:

@jjxakergm Did u know a good Tutorial or something else to do that? Or perhaps at first, did u see any performance improvements with new microcode injected by you?

20 years back i only needed a HEX editor to fiddle with the Symbios ROMs in my beloved Asus P55T2P4 🙂
For the recent UEFI boards is a pretty bulletproof tool around called UBU with a great forum.
If you don't want to risk anything and have a recent board best bet is to wait for an official Asus UEFI that surely will come soon.
For my PRIME Z370-A the recent UEFI has the Spectre fix like all other recent Asus boards so no danger in waiting.
Nonetheless i subjetively feel the more recent microcode (84 for coffee lake) mostly fixed the hiccups i had. Still the pre-Spectre speed is gone.
Latest microcode even benches slightly better. See here https://rog.asus.com/forum/showthread.php?99745-Prime-z370-a-bios-0607#post706684

For work you will need this tool: https://www.win-raid.com/t154f16-Tool-Guide-News-quot-UEFI-BIOS-Updater-quot-UBU.html
There is no performance loss with new microcodes, even with SSD.

Hey, i've updated the Microcodes for Skylake and Kalbylake on my BIOS File, i just selected C2 for Skylake, even i run a 7700k.
But my UEFI will not accept the new BIOS File, it is not a valid BIOS...

what had i do wrong?
