RAM modules are only guaranteed in the form sold (from the same pack). So it's a 50/50 gamble whether a new set of modules will work with the old. This is because the manufacturing of the modules changes frequently, making them the same make/model/timings is irrelevant. That is just a way to try and minimise potential conflict, but not eliminate it.

So not saying it won't work, but it is a 50/50 gamble regardless.

Is this to replace your current RAM or to add to it?
If it's to replace it, get whichever you prefer or is the fastest for the price.

If it's to add to your current RAM, the potential for conflict is probably the same between all of them, the best way to minimise it is to pick a module that's similar to your current (2666) at CL17 - but again, no guarantee regardless.

i would like to add it. Still its puzzling because if i buy any of the above product i dont get any replacement at all it wil be waste of money. above 3 are CL19
