I can see one has 'A' in its number and the other has 'B' ..

A and B likely refer to the source of the memory chips themselves

this is afaik corsair buys chips from other companies then packages them and slaps them all together and sells them
so A might be micron and B from sasmsung, c from hynix etc

some companies also use different number to denote the OC/quality grade but don't think corsair is doing that
