Fx is not bad but It is getting long in the tooth, as they say, I need to upgrade like really soon I have that Mod-bug starting-up again. Very satisfying putting together your own machine then the first time you fire it up, It's alive! Just for the fun of it.

Well done Micro$haft rushing a patch out before testing and rather than excluding specific identifications like "AuthenticAMD" CPUID you just install it on anything and everything, whats next Windows update going to install AMD drivers onto my nVidia graphics card? It's not the first time Micro$oft have had to pull patches due to being rushed and braking stuff... and it won't be the last either.

It's not just servers and people running VMs affected. The performance impact, per MS, is dependent on processor architecture and Windows version. Skylake and newer are expected to see a negligible performance loss. Haswell and older will see a greater but varying degree of performance loss dependent on architecture and Windows version. Servers will be the most affected due to heavy I/O based workloads.
When someone says something like "up to 30%", the statement implies that the affect will vary between 0% and 30%. Most people just have an issue comprehending what "up to" actually means. Yes, the media does have a bad habit of stretching the truth or exaggerating depending on the subject, but at the same time, readers have a tendency to read what they want and not necessarily what's really there. I've been telling people since the news broke that the performance loss for most wouldn't be anywhere near as bad as they were worried about. Sadly, people kept seeing that "up to 30%" and ignored the rest of the facts.

Now it seems that m$ might not be the only one responsible for AMD systems not booting.

Exactly, everybody's working on fixes on all ends anyway. Like stated a couple of times, I too think in the next 2 weeks everything will be patched, from BIOS / microcode to OS updates to drivers to whatever.

I just updated my bios today. No performance loss whatsoever.
Edit: spoke too soon. I had a massive drop in Cinebench after updating. Reverting to the previous bios fixes that. I don't think this all came from the microcode. Hopefully Asus can fix this.

Yoy play games or work with Cinebench??? Test what you play or work daily! 🙂
What to fix? AMD Ryzen is not affected by Meltdown,as Intel cpus.Spectre,not so much.
