    The issue is that they don't know anything different, and about that they don't think about either. Not thinking is the way of the 21st century.

    You can't use more than one BIOS for motherboard at the time if that's what you're thinking/talking about. OK you can, if motherboard has Dual BIOS with some kind of software or hardware switch to choose what BIOS you want to use prior to OS boot.

    Solution #1 is to wait for motherboard manufacturer to release new BIOS for motherboard you're using with latest CPU microcodes made by CPU manufacturer to mitigate Meltdown/Spectre security flaw. Guess in case of your Asus ROG Strix Z270F mobo that last BIOS should contain updated Intel ME but no one can guarantee you that, probably most of the manufacturers will aim their efforts just to update CPU microcode and throw that BIOS out for public as fast as they can.

    Solution #2 is to mod existing latest BIOS for that motherboard of yours using latest CPU microcode + latest Intel ME. It's not that hard but I'm almost sure only advanced users would do that.

    Solution #3 is to download and update CPU microcodes in Windows manually, you can find a lot of about it here on G3D and all aroun the web.

    Solution #4 is to wait for Microsoft to push latest CPU microcodes via Windows Update like they did in the past, June 2015:
    https://support.microsoft.com/en-us/help/3064209/june-2015-intel-cpu-microcode-update-for-windows
    Will it happen, nobody knows but personally I think it's the most elegant solution for most users.

    Shouldn't the new version of BIOS that came out 2 days ago have all of the updates from the previous BIOSes in it?

    You just use latest bios file because that file contains all of the updates that were before. For example if there are 5 bios files,let's name them 1,2,3,4,5 you need to update just number 5 because that file contains updates that were before in bios files 1,2,3,4 .. you get the point

    From Microsoft side.. I'ts look like another marketing BS to Me.
    So what causing difference in performance, between updated Windows 10 and Windows 7.
    Why performance degradation with older Windows, are more noticable..?
    It's Kernel differences.. drivers.. what ?

    I was thinking the same but i wasn´t sure that´s why i asked. Thanks everyone for the help!


    I read that it´s due to some kernel differences regarding how both systems handle the physical memory and stuff like that... Sorry about being so vague but that technical stuff is basically alien to me... I´m sure some members here with knowledge about the matter can explain this better.

    Anyway i´m still using W7 and if i notice something strange or different i´ll post about it.

    My old MSI z68a... allows to load BIOS/FW from flash drive as "Test Mode". So you can test if BIOS/FW works well before you flash.
    I do not think it is only one. My solution is simple, Intel desktop will no longer be used in way which would allow this vulnerability to take effect.

    Nice feature, didn't know something like this exist on some MSI motherboards. Tbh I'm not much in love with MSI motherboards, had used them up to AM2/AM2+ era then after swiching to LGA775 jumped into Asus train (sometimes GigaByte and ASRock mobos also) and never looked back at MSI. MSI GPU's are fine as far as I'm concerned but not so sure about motherboards, saw way too many of these dead in PC's of my friends and relatives. Last MSI motherboard I've bought was MSI Z97 PC Mate because needed something Z97 based, cheap and OC'able with HDMI for one of my HTPC's to be paired with Pentium G3258 capable of 4.8GHz (now mostly used @4GHz with Intel stock 1150 cooler) and that mobo pushed G3258 without issues to 4.8GHz with big Thermaltake Frio on top of it. Can't complain about this mobo, past few years it serves me well for daily HTPC use.

    Nobody owes you anything.
    Besides there's already real stats across various websites.

    If anything your post is that of a troll.

    Yes, seems perfectly reasonable to me.

    We're seeing up to 25% reduction is DB performance on RHEL, that really is a killer impact.

    After patching, depending on the application type, there can be a lot more context switching required. OS that are better in that area will see less of a performance hit.

    OS that support PCID running on a CPU that also supports it can mitigate performance the hit almost entirely as I understand it.

    That is a Sandybridge CPU, so older then Haswell and likely to have a more noticeable slowdown from the patch to fix the security vulnerabilities.

    I just installed the update to my MSI gaming laptop that has a 7700HQ and no issues as of yet. I have to do some further testing.
    Then why don't you show us some stats then? Since you are the one complaining. As Agent has said we owe you nothing. Plus I reported you for your troll comment.

    Performance hit on randomly rebooting Haswell systems?

    "50% of the time it works all the time."
    Or: You're running the constant risk of 100% performance hit when the patch reboots your system during use like watching anything, gaming, rendering, converting, etc. etc.

    At least Intel has more secure systems for now. All AMD systems are unprotected. No support from Microsoft because of BSODs/GSODs/Crashes on boot etc. All updates are held back. WTF AMD desparate trash. Their stocks and shareholders should go to hell, they only were talking bad about Intel huh? Now what, the whole January month until February, AMD systems are in severe danger.

    This time around I have to side with AMD. It's better to have a system not patched than a system broken by those security patches. Sure, a not booting system is not exploitable as well after the patch, but to be honest I will try to refrain from installing updates as long as my system (Haswell) is suspect to mysterious random reboots (see press releases and statements by Intel).
