I have trident z royal(yeah I know its overpriced) ram. I wanna add ram and originally I wanted another 2x8 set but i found a 2x16 for a very similar price. Both sets are same speed same latency, just different sizes. Could this be used or should I just get the 2x8

Yes you can mix 2x8 with 2x16, but expect instable system if they have aggressive XMP settings and you apply them straight away

Well, I tried mixing a 1 GB with a 2 GB DDR3 SODIMM on a laptop and it still works until now.

But, I have no idea if that's even stable to use RAM that big and mixing it up.

Humor me, as you should do.

 

Daily drivers, below.

 

Diccbudd PC

Intel Xeon E3-1225 v2 || ASRock B75M Motherboard || MSI GeForce GTX 1650 Gaming X 4G || Hynix 2x8 GB DDR3 1600 MHz RAM || 480 GB Pioneer APS-SL3 SATA SSD // 1 TB Seagate 2.5" HDD || be quiet! System Power 9 500 W PSU || Cooler Master T20 CPU Cooler || Samsung S19D300 Monitor || Fantech X6 Knight Mouse || VortexSeries VX7 Pro Keyboard

 

Samsung Galaxy A34 5G

8GB RAM, 256GB Internal Storage, 128GB SanDisk Extreme, and you could find the rest of the specs on the interwebz lol

 

Lenovo ThinkPad L390 Yoga

Intel Core i5-8365U || 8 + 16 GB DDR4 (don't ask, gf bought me the 16 GB RAM as my birthday present lol) || Samsung 256GB SSD

Would it be stable if i didnt run XMP?

It's not the fault of applying XMP, but the high frequency. You can enable XMP and manually test how high the frequency can be while the system is still stable.

Would it be worth the trouble or should I settle for 32gb

I would say yes, there arent that many numbers you need to test.

You can mix it I have a 4gb and a 8gb stick and it works fine.
