[SOLVED] 2 Ram sticks, same company but different build dates and slight xmp speed difference

[APSK]

I've got 2 of corsair's vengeance ddr4 3000 mhz. Both sticks have same timings at same voltage of 1.350v but different speeds, one is at 2998, and the other is at 3002, owing to its different manufacturing dates and source. First one is from SK hynix and is a dual rank memory, Second one is from micron and is a single rank memory.

So my queries are:
Q1. Can i run them in their xmp profiles, seeing as their voltage is same?
Q2. Will their be any possible long term issue to either motherboard or ram's or cpu itself?
Question 2, cause right now i am running a msi z390 board, the earlier board that i had from gigabyte, its ram slots got toasted (channel 0 a & b) for unknown reasons, i was running xmp at that time, and i had only one ram stick then. That Ram is running fine now in the new motherboard, and it ran fine when i ran xmp on the new msi board, but it always crashed when i ran xmp on the gigabyte board, or tried to manually overclock it above its base 2133mhz speed.
Q3. Should i really run XMP? as my game suite is warframe, elite dangerous, BDO, X4 foundations and FH4.

Specs:
I9 9900k
msi z390-a pro
2 sticks of ram Vengeance 16gb ddr4 3000mhz
cx 750 corsair psu

Thanks in advance!.
