What's the difference between these two RAM's?

[LuckyRNG]

I was looking in the overclockers site and found these two RAMs that seem the exact same other than CAS timings and voltages.

What kind of difference does this make to the RAM? and is there a "better" option out of the two.  Any information for would appreciated. (I know one of them is out of stock)

Ps incase relevant:

MB - Strix b350-f

CPU - R1600

GPU - MSI 1070ti

the voltage

voltage, timings, and one is not in stock

[jamesnightingale]

one is not in stock so you only have one choice.

Yeah I know. But I don't know what that means for the RAM.

Look for team groups dark pro 3200 cl14 if i am not mistaken it's the cheapest b-die memory you can get and it's around the same price

maybe one is dual rank and the other single rank, it's my bet

The thing is I can get the RAM I linked for £180. But thanks for the suggestion, I'll look into it!

The first one also has lifetime warranty while the other one only has "limited" lifetime warranty.
