Can I mixmatch RAM?

[himynameistree]

For example:

I have a MOBO with 2 DIMM slots,

I buy one stick of 8gb corsair ram that is 2133mhz,

later I decide I need more ram,

I buy one stick of 8gb g.skill ram that is 2133mhz,

IS THIS SCENARIO OK?

You should match the CAS latencies and the voltage.Speed doesn't really matter, the speed will automatically lower to the lowest common speed. And size doesn't matter.

As long as frequency and power usage is the same it shouldn't be a problem, but I still recommend getting same RAM sticks.

what is the latencies and voltage? where do i find that info

what is the frequency and is the power the volts?

[derpylt]

DDR3 has 1.5V
DDR4 has 1.2V

DDR2 has 1.8V

what is that?

It would say in the specifications, CAS latency is a set of 3 numbers, 9-9-24 is a CAS latency. And voltage ot would say, 1.5V is pretty common. Just check the spec sheets for the RAM.

[himynameistree]

so aslong they are both ddr4 it is ok? what is the frequency, is it the 2133mhz?

The voltages and the Latencies have to match. Ya thats the frequncy.

so far I understand:

they both have to be ddr4, they both have to be same frequencies e.g. 2133mhz.

is that correct^^

 

thanks for the help

 Latency is a set of 3 numbers like 9-9-24. This has to match.

Voltage is in volts, for example 1.5 V is common, This also has to match.

Frequency should be matched.

They both have to be DDR4.

I'm struggling to find info about latency, where could i find it?

take a picture of your ram or send us some link

 

I would never recommend to use differend RAMs in your system. It's best if you can get identical rams.

nvm I found the latency, I think I have everything sorted

anyway, another question: What's the difference between notebook and desktop ram??

@himynameistree
Are you afraid of buying a single/dual ram kit, and it going out of production in the future when you decide to upgrade again?
I don't think you should have any worries, especially not when looking at Corsair and/or G.Skill
Buy one/a set of those, and I'm sure they'll be available in 1-3 years still, at about the same price or lower

As others have pointed out, they wouldn't mix-match their ram; I don't have much (*cough* any) experience with this, but I've read the same as well while upgrading my own computer. And glancing over most of the different rams, they all seem to have different latency.
And about voltage: I'm not sure about other ram, but my corsair "needs"/wants 1.65v when using XMP - Mostly, others, will only need 1.5v if I'm not mistaking.

The main difference in Laptop and Desktop ram is the size, iirc - I'm not sure about the performance
I think they're labeled with an L, or something. Again I'm unsure (and I'm about to go out the door, so I can't check ^^).

 

thanks

quickly, is this ram good? https://www.mwave.com.au/product/geil-pristine-8gb-ddr4-2133mhz-memory-gp48g2133c15sc-ab67941

The difference between laptop memory and desktop memory is physical size and its pin configuration. 
That being said, you can't use laptop ram on desktop and the other way.
