ASRock - BIOS updates for older chipsets vs. Spectre/Meltdown

ASRock published a huge dump of new BIOS revisions with security microcode updates yesterday and today. I see updates for the following chipsets: H97, Z97, X99, H110, B150, H170, Z170, Q170, and C232. Some of them are under the "Beta BIOS" sections so make sure you check that too if you don't see it in the normal downloads category. It looks like the vast majority of the boards they are officially covering have updates now. I only see a few outliers like some H270's are updated and others aren't. They do also mention 8 series which I assume to mean H81 & B85 but those haven't had updates in years and the previous press release started at 100 series so who knows...

W00T! My Fatal1ty H97 Performance 2nd box has a new v2.60 BIOS for this. Love their laziness: "Update CPU Microcode."

Excellent find. Thank you.

The update process is just as easy as a regular BIOS update, only takes an extra couple minutes.

This was the worst drop I noticed in the benchmarks I ran before/after. Pretty much everything show small but negligible drops only a few tests were significant.

I been thinking which way to go, only today I just installed the windows meltdown patch but then have already disabled it. I have a lot of mitigation's on my computer so the bad boys already have to jump through hoops to even get the chance to run this type of code on my system.

Certian types of instructions will have no hit, others heavy hit, and the loss you see in tests like this is the whole thing been averaged out.

For spectre I need to upgrade my bios, and my previous testing of newer bios's for my board wasnt good due to LLC (current bios I am using has no LLC as is broken, which is working well for me), so to get a spectre fix I need to deal with that, but also then I have the performance hit. Right now I am leaning towards keeping my performance. Especially as these are not even actual fixes but rather just hardening and against an exploit that has had no known use in the wild yet.

People on cloud services in datacentres have reported a halvng of performance (doubled cpu usage), its scary on the performance overhead in my view. This partial mitigation is setting cpus back a decade in performance.

FWIW, Asrock has z77 bios updates listed as beta on their website. FWIW, it did a complete wipe of my saved OC profiles. Not earth shattering, but an annoyance. Haven't benched.
