Can you add 2x4GB of RAM to 2x8gb RAM?

If you’re MB has support for that amount of ram then YES it’s safe and NO-PROBLEM-AT-ALL. Just mount them 8,4, 8, 4 for maximum compatibility.

Can I use different frequency RAM in dual channel?

Yes, you can. A prerequisite first: BOTH sticks need to be of the same generation, e.g. BOTH have to be DDR3, DDR4, etc. If you got that nailed down, it’s pretty simple afterwards: you just plug both sticks into the system. The faster stick will operate at the frequency of the slower stick.

Can you put 2 different sizes of RAM in a computer?

There’s a prevailing misconception you cannot use different RAM sizes together or that you cannot mix RAM brands. Simply put, that’s not true. The answer is Yes, you can mix RAM sticks and RAM sizes and even different RAM speeds—but mixing and matching RAM modules isn’t the best for system performance.

Can I add 8GB RAM to 2x4GB?

Hello, You can still use the RAM in dual channel: put the 8GB stick in the first slot, and the 2x4GB pair in the third and fourth slot; one channel will use the 8GB stick, and the second channel will use the cumulated 2x4GB kit.

Can I use 2x 4gb and 8gb RAM together?

Yes you can. And you’ll get the full 16 gb too. But here’s the thing, Games use dual channel memory to collectively read and write information. Using an 8gb stick with 2x4gb sticks will prevent dual channel interaction as the games will only be allowed to communicate with either the 8gb stick or the 2x4gb sticks.

Can you install 2 RAM kits?

Yes, it’s very nearly perfectly safe, even if they’re different kits from different manufacturers running at different speeds, as long as you follow the directions in the motherboard’s manual. The main things you need to watch out for are channels, CAS latency and other timings, and speed.

Can I have 2x4gb and 1x8gb RAM?

If the sticks will play nice, (no guarantees ever when mixing DRAM, even with an identical set to what you have) and if your mobo is Intel or a fairly current AMD then they will be fine and contrary to the above, they can fully run in dual channel (will prob want the 8GB in slot 1 closest to the CPU (channel A) and the …

Can I mix 8 and 16 GB RAM?

Yes you can mix memory modules. However keep in mind, your system will only be as fast as “the slowest member”. I encountered a laptop where the owner had swapped memory modules from other systems to end up with 24GB of memory. It is doable to do 8GB & 16GB in a two slot DDR3 & 4 systems.

Can you combine 2 16gb kits?

Mixing kits / modules is never really advisable, as there is no solid guarantee that they will play nice together, even if they are identical on paper. That doesnt mean to say that definitely will not work, but there’s always the chance that they could cause issues.

Is 2x4gb Ram faster than 2x8gb Ram?

So the single 8 GB part of RAM would not be as fast as 2x4GB. I have an older PC and was going to get 2x8GB sticks of 1333 RAM to upgrade 4x2GB 1066, but fortunately looked up ahead of time and discovered that 4 GB was the most my PC could use in any off its 4 slots.

Can I use more than 4GB of RAM?

Your spec says you have 32 bit OS, so more than 4GB will be not be usable. To use more than 4GB you will need 64 bit Windows. Also I just looked up your motherboard manual at Asrock and it says when using all 4 ram slots, to use identical sticks

Is it safe to mix and match DIMM RAM?

If PC with mixed DIMMs boots (what it usually does) it will run perfectly stable. Get another identical 2x4GB kit instead. You shouldn’t mix and match RAM as it could cause problems and reduce system stability. If PC with mixed DIMMs boots (what it usually does) it will run perfectly stable. Yet no dual channel.

Is 8GB of RAM dual channel?

Yes. Can’t you get another 2×4? an even number of RAM sticks of the same type would be advised most. It doesnt just prevent possible problems but also is the best to using dual or quad channel. Depending upon which slots they are in, the single 8 GB would not be dual channel (in a desktop) at least with Intel (not sure about current AMD).
