Can i mix RAM memory?

[ayoub20600]

Hi guys.
I have 2 RAM slots 4gb in each one, and now i'm thinking by buying another 2 slots of 8gb in each one. The have the same freq and timing. The idea is puting the New RAM in the 2 and the 4 slot in the mobo, by doing that, Can i continúe having the dual Chanel config or not? Do i'll have any problem in the future? This config its for playing and doing renders.
PD: sorry for my english, and my mobo suport 32 gb of RAM, and i have any i7 4770K.

yes, in theory you can do it.
most probably it will work without issues.
less probable, you will have to set the clocks and timings manually in bios.
even less probable, kits will refuse to work together. very rare.

It's a crapshoot - 50/50, they might play might not, see my Fiction article, items 2 and 6

If you try and they don't want to play give a shout and we can try adjustments 😉

Actually i have this RAM: https://www.amazon.es/G-Skill-Ripjaws-X-memoria-DDR3-2133/dp/B005C8R3LO/ref=sr_1_4?s=computers&ie=UTF8&qid=1472989984&sr=1-4&keywords=ram+ddr3+2133+mhz

and i'm wondering to buy this one: https://www.amazon.es/G-Skill-RipjawsX-16GB-2133MHz-m%C3%B3dulo/dp/B00MJ96E00/ref=sr_1_3?s=computers&ie=UTF8&qid=1472989984&sr=1-3&keywords=ram+ddr3+2133+mhz

So by reading the post. What do you suggest me? buying the 16gb (2*8Gb) and replacing it of my 8gb existent, or buying 8GB (2*4Gb the same model that i have) and upgrading my existent RAM?

OC buying the 2x8GB kit.
than first try to use them together - most probably will work without issue.
if it will not work, post here and we will try to resolve it.
best case - you have 24GB RAM
worst case - you have 16GB RAM which is more than enough and you can sell your 8GB kit

Ok i will keep you in touch.

Well. Today i receive another 2*4Gb of RAM (same model and spec that i have) and it works fine. I didn't buy the 2*8Gb coz i don't need more than 16gb. I've read in the forum that 2*8gb works on Dual chanell and 4*4gb doesn't work. It it true?
PD: my mobo is this model: http://www.asus.com/Motherboards/Z87DELUXE/overview/

4x4GB will work fine, 2x8GB is better as it's less stress on the MC (memory controller)

Nice MB.
The 4x4GB work in dual channel mode
you just place the memory in all slots.
If you had only 2 sticks like before, you had to use them in the same color slots for them to operate in dual channel mode

I can replace them by 2*8G if i will, coz i bought it from amazone. I thought 4*4gb will do great coz it less stress of 2*8gb.
What you suggest, keep the RAM or replace it?

 

[Tradesman1]

Less sticks is less stress - just want to keep enough to maintain the dual, tri or quad capabilities of the given mobo - your mobo supports only single and dual so want 2 for dual unless maxing out the full 32 max it can handle 😉

 

[n0ns3ns3]

Keep it.
there is no need to replace what you have. The stress is not important as i doubt you going to overclock the memory to insane values

ok. because over 2133 MHz the system crashes in stress test, si with 2133 all things runs fine.
Thanks for helping me.
