Changing RAM based on BIOS

[PacMappy Solvalou]

So this is part 2 of an existing problem I have. Part 1 below: 

Some additional details with my system (that were not mentioned from Part 1) are that I have an Aorus B650M Elite AX mobo (smbios ver 3.6; bios ver F21 from Jan 10, 2024)
The existing RAM kit currently in the system is https://shorturl.at/TJOWm which was purchased Nov 2022 (RMA not possible at this point since its well more than a year) and, as from Part one from above, has gone bad. I plan to switch the RAM to this kit https://shorturl.at/cGIyg with the only difference being a CAS of 30. (or any other compatible ram kit suggestions are welcomed)

Is the bios update unnecessary if I buy the exact same RAM kit spec for spec as the old one? If I switch to the new RAM kit, should the bios be updated to the latest version? (per Gigabyte/Aorus' website, bios is F30 from Jul 5, 2024) 
Or would the bios be updated regardless just to ensure compatibility among new(er)ram kits?

BIOS updates shouldn't have any impact on RAM compatibility. Leave the BIOS alone unless something breaks and you want to reset it. As long as everything boots the first time with the new RAM then don't touch the BIOS, if it doesn't then you try updating the BIOS. Basically, if it ain't broke don't fix it.

It actually can have a fairly major impact. There are many instances where there needs to be a BIOS update to work with specific memory chips (I.E. Samsung 8Gb B die on early X99 boards or Micron 24Gb Rev. B on AM5), or memory PCBs (the A2 layout of DDR4, for instance, clocks like crap on X99 and Z170/Z270 boards because they don't have the appropriate BIOS support, and Z370/Z390 boards usually need a BIOS update to work properly with them). 

 

 

This is not one of those times, however. That 5600 CL30 kit is going to either be a really good bin of Samsung 16Gb B die or a mediocre bin of Hynix 16Gb M die or 16Gb A die (my money would be on M die). All of those memory ICs have been supported since the first BIOS revision of the B650M Elite AX, rather well I might add, so a newer BIOS revision isn't likely to change anything too significantly. Update it if you want to, but I personally wouldn't bother.

Sorry, this is what I meant to say, that for newer systems it doesn't matter, MB that this wasn't clear.
