Hey David, glad the article helped you out! Of course, these things always depend which is why it’s great you can test, but I expect the 16GB set will have a good chance of giving you a smoother system, best of luck!

I bought a new Dell Latitude 3520 with i7 and 8G, that has DDR4 SODIMM 3200 MHz chips, but have 2 16G DDR4 2666 MHz chips in a Shuttle that I’m not currently using and was wondering if they would be better or worse. Since the xG is the biggest factor, I think I’ll give them a try and see how they work. They’re CL19s ‘tho, which may not be so great. But if they’re glitchy, I’ll just swap ’em out and buy some new ones.

It’ll be an interesting experiment and hopefully I’ll learn something in the process. Thanks again for all the great info!

It’s a tough question to answer as it depends on usage, your setup, etc. but in general, I would expect the 2 x 8GB to be better for you; getting to use dual-channel RAM is typically going to be more important. I would say that if you ever planned on upgrading, however, running 1 x 16GB and buying a second stick of the same RAM later would also be a good option.

Hey Leo, yes, both of your questions are possible, but they’re often not ideal and can sometimes be compatibility issues. If you are using different sticks, they need to be the same voltage and will likely have different speeds, latencies, etc. which can make your build run less efficiently.

To put it simply, there’s a reason RAM is often sold in pairs – > Running the same RAM sticks 2 or 4x (as memory works best dual channel) is really the ideal.

Hi Andrey, as always with these things it’s hard to give the perfect estimation because it depends dramatically on individual spec versions/games you’re playing, etc. But with that said, I would say that you could roughly expect ~5% FPS improvement if you were to upgrade to a 4000+ Mhz RAM set (assuming latency/size same as your current set).

Though this will likely be an expensive upgrade; if you’re very price-focussed and JUST interested in gaming, I can’t help but feel like it’ll be more important for you to save up for your desired GPU; as far as iGPUs go, the UHD770 isn’t bad, but the RAM is not going to be bottlenecking your experience anywhere close to the UHD770 is (personal opinion, but I also don’t see GPU prices as much as some expect for some time, so it might be worth putting all of your funds into a dedicated card).

Hope that helps 🙂

You’re welcome!
