When I first built this rig in 2015 everything was quite new and I recall that in order to get the M.2 and the RAM to cooperate I had to do a bios update. I have the original motherboard manual printed, when new, and it says it supports Gen 6 i3, i5, and i7 LGA 1151 processors, though I have seen somewhere that it may support 7th gen processors also. Currently my bios is updated to version 1.70, will I be able to use a 7700K without further bios updates?

Not sure on the bios update for intel or not but usually the MOBO manual claims like you say it does what chipset it will support. I didn’t think an update to the bios would allow a newer cpu. I could be wrong. I’ll do some research as well. I know for example my AMD board accepts most Ryzen CPU’s regardless of bios version. Granted I did update to current version, but the chip would have been compatible either way

Was just typing that it does show compatible for that board on MSI website but a bios update will be needed. Like they said prior, so it with the working configuration before you drop in the new cpu

Yeah, it is a bit confusing with Intel right now. They've kept the 'same' LGA1151 socket for 'four' generations now. But typically they have always supported sockets for at least two revisions of CPUs. But isn't always so easy.

So your Z170 and Z270 boards will take 6th and 7th gen chips and the Z370 and Z390 boards will take 8th and 9th gen chips. (There are some exceptions in the asian market with H310, but for Europe and NA you won't be seeing cross compatibility without some modifications)

Previous LGA1150 socket was divided into two camps. Z87 and Z97 supported 4th generation Haswell and Devil's Canyon refresh chips, but only Z97 supported the limited release Broadwell chips.

LGA1155 had 2nd gen and 3rd gen chips on it.

LGA1156 was somewhat shortlived with pretty much just the 1st gen chips.

AMD has always been big on cross compatibility. They like being the cheaper alternative. So on a lot of the older boards you could drop new CPUs into older boards, but sometimes they would run a little slower on the older platform. So you had AM2 boards, AM2+ and AM3 boards. So each socket spanned two generations at least of CPUs. With AM4 it looks like they planned ahead and basically all the boards are more or less cross compatible.

The last BIOS update was in 7-2-2018 so If you done one recently you should have the latest. And on the website it list it as supported.
