Hi, so the other day. I finally thought to myself, I should probably upgrade my RAM.

 

I have a 2X4 GB kit from Team Elite and was planning to add Two more of them so its 4X4GB, I have A b460m ds3h from gigabyte which comes with 4 Dim slots 

 

And I was wondering if i can add two more dual channel RAM into it.

 

Can i do it? Or should i just buy a 2X8 GB kit

Which CPU do you have its important and do you want fast ram or only much?

When you have a Xeon or similar Cpu 4x4 when you have a normal desktop cpu 2x8.

4 sticks is not always better.

 

Unless we're talking Threadripper or other very high end Intel processors, majority of processors on the market have a dual channel memory controller, where each memory channel can support a maximum of 2 memory sticks.

So, you get the most performance when you use at least one stick on each memory channel, so two memory sticks. If you install four memory sticks, you won't get better performance, it's still just two memory channels transferring data to the processor cores.

 

In fact, when you have 4 memory sticks installed, there's double the amount of signals going between the memory slots and the cpu socket which means there more 'noise' inside the circuit board and the memory controller inside the cpu has to work harder to receive the data and correct any small errors that may occur.

Because of this, you may find that on cheaper motherboards, you may not be  able to run 4 memory sticks at high frequencies like 3200 Mhz, but the very same memory sticks would run just fine at 3000 Mhz - at lower frequencies each bit of information stays just a tiny bit more on the wires between cpu and socket and the memory controller inside the processor has a bit more time to decode these weak signals and detect correctly if it's a zero or a one bit.

 

So you should always install as many memory sticks as the amount of channels the memory controller inside the cpu has, or double the amount (but double that amount won't give you more performance).

For socket AM4, you have two memory channels. Threadripper has 4 memory channels, so you should install 4 sticks. 

There's some Intel processors which have only 3 memory channels and in the past, AMD had socket AM1 or FM1 if I remember correctly which had only memory channel.

I have a normal desktop CPU, An intel core i3 10100F

Also another thing to note, Intel CPUs are not very sensitive with the memory speed, so 2666MHz RAM would be sufficient.

You should always use a kit that comes with all the ram together, don't mix ram.

I tried this and my gaming was slower when I mixed ram

Miss matching RAM is very random, most of the time its fine but you can get a scenario where the memory sticks hate each other or the motherboard has no clue what the hell you are doing and has a mental break down.

 

Worst case scenario is the sticks are not compatible and a pir of the sticks gotta go, now if you buy another 2x4 it most likely will work but if you buy a 2x8 trying to miss match then with your 2x4 it may also work but I suspect the older sticks most likely use A0 PCB layout while the new 8GB sticks probably use the A1 or A2...
