Hi,

Currently I have kingston hyperX 2x8gb ram with 1866mhz, and i was thinking about getting an update.

I would like to buy at least 3000 mhz 2x8gb ram this time. and my question is: how should i choose? I heard that different manufacturers dont go very well together, or should i look for kingston only? so: is it a problem if i want a different manufacturer? is it a problem if the new ones have higher mhz? 

I would really like them to work together and i'd get 32 gb. but if thats not possible im OK with 2x8gb 3000mhz only but yeah. soo anyone? :P

Make sure you pc can support 3000 I know some only support 2700mhz. I don’t know personally but I’ve that as long as they are the same size 8gb, 16gb etc... then the brand doesn’t matter all that much.

listing what machine you have might get the answers you're after.

Usually RAM go together, let's say you have 4 gb  kingston at 2500 mhz, and you want another ram to upgrade to 8 gb, you should get another 4 gb of kingston 2500 mhz or get a pair of another brand lets say crucian 4 gb x2  ..

so if i have 2x8gb right now then the optimal thing would be 2x8gb too. but my question is that if i have 1866mhz then a 3000mhz pair would fit it or not :P

You could do 2x16 to get your 32gb. I just remember reading that it’s better to have the 2 of the same sizes than to have like a 8gb and 16gb in there together (again what I read when I was researching.

You need to google your motherboard to see what memory speeds it can handle.

3000Mhz can be an XMP overclock for some quite cheap 2x8GB kits. You don't need to look for 2 different 8GB cards if you get 2 of different speeds the system will often default to the lower speed.

Hi parisstatham,

The memory speed is dictated by the memory controller, typically included as part of the CPU.  So your CPU is one of the biggest limiters in RAM selection.  There are "standard" speeds, and there are "non-standard" speeds.  The "non-standard" speeds are generally where you get into trouble with compatibility.  You should plug your CPU into the Intel Ark https://ark.intel.com/ (assuming you have an Intel CPU) and check out what your "standard" speeds are.  If you want to roll the proverbial dice, check out https://www.crucial.com/ and find what memory they list of your system, to get an idea on what it will support.  I would be surprised if your current system runs at 1866MHz, that it would also support 3000Mhz.  Plus, unless you are going for bragging rights and artificial benchmark scores, the amount of RAM (and type, dual-channel or single-channel) is far more important than clockspeed.  If you are in a memory constrained situation, more GBs of slow RAM will be loads faster than lesser GBs at faster speeds.  Good luck!

hmm. thank you guys. I have an I7-4790K btw so I think it should be able to handle higher mhz of RAM. but I got my answer then. I should just replace the current 16 gigs with higher mhz and that's it, instead of having a mix of "old" and new 32 gb.

This might end up being a stupid question but are you sure the ram you're looking to get ddr3?  I know they also have 3000Mhz ram for ddr3, but it's not a typical frequency and is some legit high end stuff.  3000Mhz is more of a typical ddr4 frequency.
