Adding more RAM - trying to match timings

[k2focus]

Hello all.  I have an 880-122na with 16GB of RAM (2x8).  I'm looking to add another 2x8's, but I'm finding it very hard to match.  I see that I can probably order the HP stuff, but it's pretty expensive.

I'm looking for 2666 MHz with 19-19-19-43 timings.  The only one I can find is this one by Elite: 

TEAMGROUP ELITE PLUS 16GB (2X8GB) DDR4 PC4-21300C19 2666MHZ DUAL CHANNEL KIT

It's selling for £80 on Overclockers.co.uk, which isn't bad at all, but I've never heard of Elite before.  Anyone else do some RAM upgrades and run into issues?  Is mixing RAM with different timings an issue with these motherboards? I know you should avoid it if possible, but just curious on thoughts from people.

Thanks.

Hello @k2focus 

You are wanting to populate the other two empty slots. Does the new ram need to match the old ram?

You don't have to match the old pairs timings, but its better if you do. The two new sticks will have to match each other, but if they don't match the old set, the system will run both sets at the slower sets speed. Voltages have to match all across though.
