Can I use dual channel memory with one stick of ddr4 3000 mhz and one of same model with 3200 mhz speed?

Yep, they'll run at 3000 for both then.

Yes, but it is not garanteed to work. 

Also, you might see different XMP profiles in BIOS. I'd choose the one for 3000MHz.

Your motherboard / BIOS will configure both sticks at the frequency and memory timings supported by both , so they'll both run at 3000 Mhz.

 

It's possible the motherboard will go "better safe than sorry" and leave the memory sticks at 2133 Mhz or something <= 2666 Mhz and leave it to you to increase the frequency to 3000 Mhz manually  (in which case you may have to configure the timings and possibly voltage as well).

Actually I have a b460m board so the 3000 mhz ram is running on 2666 mhz anyways....

So they both will run at 2666 right?

[mariushm]

Yeah, they should run at 2666 then, but should go in BIOS and check that it's actually configured at 2666 Mhz after you install it.

Thank you so much

Means I will have no big issue right(actually I have enabled xmp of my board and running my existing stick at 2727 mhz. So will I be able to go in the bios and enable xmp for the new 3200 stick to run both at 2727 mhz?)

Yes, you won't have issues.  Regardless of XMP or this or that, they'll run at the slower of the 2 sticks or the speed your BIOS dictates.

 

And they'll 99% work together if you're right that they're the same brand, type, etc.

If they're different brands or even same brand but different "series", it's a possibility the SPD presets (the data that tells the bios the stick can run at certain frequencies) will be different between the sticks. So your original stick may have a preset that says "i can run at 2727 mhz"   but the other stick may say "i can run at 2800 mhz"

 

In your particular case, the motherboard or better put the bios, limits you to 2666 mhz, so the bios should look in the presets of both sticks and pick the most compatible preset from both sticks and use that one, and ignore the ones with more than 2666 mhz.

 

So to stop you from asking questions again.. Yes, you can install both, Yes they'll run,  Yes, they'll run at 2666 Mhz or whatever frequency is supported by both sticks.

Worst case scenario without manual intervention the sticks will run at 2133 or 2400 mhz

yupp they are litrally the same sticks one is 3000 and other is 3200 thats it
