Just to be sure... if i downgrade the Bios to an older version, Would that remove the Spectre/Meltdown patch? or it's saved somewhere else in the CPU.

The CPU cant save anything, so its not in the CPU.

Gigabyte z270x Aorus Gaming 5... I've experienced some performance drops since i installed the latest bios which contains a "cpu microcode update" and I would like to go back to one of the following:

 

https://www.gigabyte.com/Motherboard/GA-Z270X-Gaming-5-rev-10#support-dl-bios

 

Let's say i don't care about the security patches and i roll it back to the F7 version, the biggest question is...

 

Would that remove the cpu microcode update?

 

Or is it pointless since it won't remove the microcode update from the CPU?

 

Thanks in advance for any help you are able to provide.

im pretty sure you can. I found a tomsharware forum post about downgrading to older versions than you, but I think what they still say applies.

Not sure if it will apply to your newer z270 mobo bios, but based on what they're saying I think it should.

I'm sure if you look up "downgrade gigabyte z270 bios" you'll find some stuff, thats how I found the post.

You d finitely can just go ahead and flash an older BIOS on your board.

If it is a good option, I'm not so sure tough. The microcode updates are probably related to security, hence the performance drops. 

If you don't really care about that tough and you don't have sensitive data on your PC then definitely go ahead and downgrade your BIOS!

You should be able to feed the BIOS updater any BIOS and it should happily take it. Though I can see some manufacturers going "this is an older version, not 'updating' to it."

 

For those there are tools available to force update the BIOS to an older version, but let's see if the "obvious" answer works first.

Be aware that the patch is probably for meltdown, which is a pretty serious security flaw...

Don't ask to ask, just ask... please 🤨

Sauron'stm Product Scores:

Spoiler

Just a list of my personal scores for some products, in no particular order, with brief comments. I just got the idea to do them so they aren't many for now :)

Don't take these as complete reviews or final truths - they are just my personal impressions on products I may or may not have used, summed up in a couple of sentences and a rough score. All scores take into account the unit's price and time of release, heavily so, therefore don't expect absolute performance to be reflected here.

 

-Lenovo Thinkpad X220 - [8/10]

Spoiler

A durable and reliable machine that is relatively lightweight, has all the hardware it needs to never feel sluggish and has a great IPS matte screen. Downsides are mostly due to its age, most notably the screen resolution of 1366x768 and usb 2.0 ports.

 

-Apple Macbook (2015) - [Garbage -/10]

Spoiler

From my perspective, this product has no redeeming factors given its price and the competition. It is underpowered, overpriced, impractical due to its single port and is made redundant even by Apple's own iPad pro line.

 

-OnePlus X - [7/10]

Spoiler

A good phone for the price. It does everything I (and most people) need without being sluggish and has no particularly bad flaws. The lack of recent software updates and relatively barebones feature kit (most notably the lack of 5GHz wifi, biometric sensors and backlight for the capacitive buttons) prevent it from being exceptional.

 

-Microsoft Surface Book 2 - [Garbage - -/10]

Spoiler

Overpriced and rushed, offers nothing notable compared to the competition, doesn't come with an adequate charger despite the premium price. Worse than the Macbook for not even offering the small plus sides of having macOS. Buy a Razer Blade if you want high performance in a (relatively) light package.

 

-Intel Core i7 2600/k - [9/10]

Spoiler

Quite possibly Intel's best product launch ever. It had all the bleeding edge features of the time, it came with a very significant performance improvement over its predecessor and it had a soldered heatspreader, allowing for efficient cooling and great overclocking. Even the "locked" version could be overclocked through the multiplier within (quite reasonable) limits.

 

-Apple iPad Pro - [5/10]

Spoiler

A pretty good product, sunk by its price (plus the extra cost of the physical keyboard and the pencil). Buy it if you don't mind the Apple tax and are looking for a very light office machine with an excellent digitizer. Particularly good for rich students. Bad for cheap tinkerers like myself.

Just to be sure... if i downgrade the Bios to an older version, Would that remove the Spectre/Meltdown patch? or it's saved somewhere else in the CPU.

It would be gone.

Old or not it lets anyone do anything on your pc remotely without leaving any trace - if left unpatched.

Don't ask to ask, just ask... please 🤨
