First of all, it's not advisable to run 2 separate memory kits, even if it's the same brand & model.
If you want 32GB total, buy one 4x8 or 2x16 GB kit.
Each kit is designed and tested to run in dual or quad channel.
I've seen ASUS tech support advise to update to each in order of bios release.
However, you should be fine updating to the latest regardless of which version it came with.
