You know once upon a time i was an expert in these things

alas these days im so out of the loop its not funny.

I have 2x sticks of corsair vengence 6000MT ram and i just picked up 2 more from a guy selling locally, what i didnt check was the fine print!

The new set is XMP and the original is EXPO (im on a 7800X3D)
Old chips are SK Hynix new ones are Micron.

Now my question is, im not after the crazy fastest performance of all time, i play some games, i have a 4070ti, but im an old man.
1)is this speed THAT bad?
2)Can i juice it without expo/xmp without spending my life in the bios?
3)is the best option to get 2x32Gb sticks and just sell these 4 on...

Opinions?

Just manually set the timings?

I have 128GB (4x32GB DDR5, two matched pairs, and the serial numbers are off by 2, so someone managed to get the other pair in between my two sets) and it runs at 3600Mhz with a 7950X. And it doesn't really experience issues for performance (It's not noticeably slower than my 9800x3D rig with 64GB DDR5 at CL30 6000Mhz). But another of note, is that the 7000 seris of chips can't run 4 x Dual Rank RAM at full speeds anyway, they will always default back down to 3600Mhz. So really you're looking at either:

A. Faster Memory settings at lower total amount of RAM (96GB via 2 x 48GB DDR5 at 6000Mhz CL30, etc)
B. Larger Total Memory run at lower speeds of 3600Mhz (maybe if you tinker, up to 4800Mhz) (128GB+ via 4 x DDR5 combinations)

If you're not going to be using lots of memory (You'll know if you really need it), you might as well just head back down to a smaller amount of memory ran at faster memory speeds instead. Although the x3D chips design does mean they're not as pushy about memory speeds as the normal chips are.
