how important is to update the bios?

[RJARRRPCGP]

Hi all, my B450 Tomahawk max runs on 7C02v35 since I bought it. now on msi support page I see that we are on version 7C02v39 (the lates stable one). The changelog says " Updated AMD AGESA ComboAm4v2PI 1.1.0.0 ".
Is it necessary to update or I can skip?
I know that you shouldn't update your bios of everything works and many things can go wrong.
But can this help me with bios time before loading windows and maybe memory oc?

The Tomahawk that isn't the "Max", has the BIOS versions named differently. The latest non-beta, is 7C02v1E. That's what I have.

There's now a beta for the variant of the B450 Tomahawk that I have, which is called 7C02v1H1, which I never saw on MSI's BIOS web page until this week! I started thinking that MSI EOS'ed the B450 Tomahawk, already!

The beta BIOS, also is said to have 1.1.0.0.

i have a crossfire hero viii wifi i wanted to go back to a bios previous to 3003 but this is impossible .. i downloaded the previous bios and put on a stick formatted in fat 32 but from bios it tells me that the bios is not suitable .. and it is possible that it is not can you go back from the bios 3003? I state that I downloaded the right bios for the motherboard. a month ago I was able to go back from this bios now there is no way .. do you have a solution?

Unless you encounter issues that are confirmed to be bios related such as compatibility, then don't update the bios cause if anything, a bad bios flash will be very, very bad

yes sure never touch what works unless it works in my case i found this bios 3003 that for my system does not stabilize my machine with crossfire hero viii wifi cpu ryzen 3950x and 128 gb of ram certified by asus at 3600mhz

A general rule of thumb is that you do NOT update BIOS if everything works fine.

While used to be true, updating a BIOS is not the ricky task it once was.

With your situation, as @EarthDog described eariler, you would benefit from the features additions as well as stability improvements on offer by the update, especially in your situation with you having the original shipping BIOS version. In you case, I would recommend it.

That's what I did and it was worth

I bought my first UPS for exactly that reason.

No problem man

Another quick update
Today I tried to play with PBO to see if anything changes

Now PPT in my testing is always set to 90w, TDC wasn't touched. The only thing I played is EDC

With EDC set to 70A, the one I used for the last year i get about 9226 pt on CB R23, core clock stayed between 3950Mhz and 3975Mhz
With EDC set to 90A, the standard I get 9232pt, core clock between 3950Mhz and 3975Mhz
With EDC set to something stupid low like 7A (I read on another formum that it is a trick to make it boost more often to the advertised max clock speed) i get 9330 pt and the core clock is between 4000 and 4025/50Mhz

Now the question is is it safe to use 7A on the EDC or am I risking to burn my cpu?

Any suggestion?

Not every motherboard has CPU-less bios flashback or dual bios

Your point?

It should be fine, I'd say putting in a ridiculous figure either way will be ignored and the system falls back to a default.

On a brand new motherboard: UPDDAAAAATE NOOOOW

On an already working system: Don't update until you update hardware, or you want to test out new features.

To be fair, that BIOS was old enough to be absent a few new features.

Glad to hear this thanks

Soyo SY-5EMA+, (socket 7) was the first DIY system motherboard I had! It had a K6-2 450 Mhz and 128 MB of Kingston PC100/133 SDRAM. Unfortunately, the first power supply I got, was the Deer DR250ATX!
Built in December, 2000, most likely! In summer, 2001, I got a Soyo SY-K7VTA-B (socket 462) motherboard and an Athlon T-bird 900 Mhz processor. Same power supply and RAM.

BTW, I still sweat bullets with Prime95 tests!

I also had before with x.264 (IIRC) 2-pass encoding=Expect a CPU-related BSOD error code if core(s) unstable! Fortunately, with my Core i7 Extreme 965, (first gen Core i, 4 cores and 8 threads) I only got "WHEA_UNCORRECTABLE_ERROR" SOD once, (it was a screen of death with bizarre colors, like the PSU was bad, when it wasn't, LOL) with reason being "Internal Timer Error", because of turbo core or C-states and the like. (That incident was in December, 2017)
