That is a good point Wardog.

To the thread starter, I would advise that you change your user name under the "member control manager". It does not have to include your email address. I am unable to do it for you as my moderator privileges on the forums do not extend to user accounts.

And OP, did you really intend to put an email address in as your User Name here?

That's gonna earn someones email a bunch of SPAM in someones Inbox.

That's a good thing too. Matched set/kit/sticks if benchmarking or overclocking. Period.

That is the one yes. Though much like when it comes to overclocking RAM or raising BCLK, sometimes there is "flex" support even when intel says it isn't possible. Knowing what CPUs unofficially support it is all but impossible to know without testing them however, its not like reviewers test mixed memory setups Tongue]]> Wed, 02 Dec 2015 16:25:08 +0000 https://forum.asrock.com/forum_posts.asp?TID=1395&PID=6389&title=asrock-z170m-pro4s-and-ddr4#6389 <![CDATA[Asrock Z170M Pro4s and DDR4 : wardog wrote:I though Intel...]]> https://forum.asrock.com/forum_posts.asp?TID=1395&PID=6388&title=asrock-z170m-pro4s-and-ddr4#6388 Author: wardog

The simple answer is yes. You will sacrifice dual channel operation with 3 modules and it is very likely that the mixed capacity dual module setup will run in single channel too. I have seen mixed capacity setups run in dual channel but it largely depends on the CPU memory controller and the BIOS. Officially you need only Xeons are capable of mixed capacity dual channel but sometimes it works anyway, just like some manufacturers add overclocking features to boards using chipsets intel never intended for the purpose. 

In other words, if you don't mind losing dual channel performance and defaulting to the lowest frequency of RAM installed (2400 in your case) then it should work so long as all the RAM you install is compatible with your board. I always advise against setups like this, it is far better to have matched kits as they will run at the same speeds, timings and likely be more stable. I do however see systems with mixed RAM pretty often, especially in the "upgrade as I can afford to" bracket.

Good luck

Hello I have a Asrock Z170M Pro4s motherboard. It takes DDR4 memory

Can I mix the memory or does it have to be the same. Can I put in 8gb+4gb to make 12gb ?
Can it be from different manufacturers? Can it be different speed like 2400 and 3000 together.

Can I put in the motherboard a 8gb (Crucial) and a 4gb (Crucial or Corsair) stick in the same channel? (2 sticks total)
OR 
Can I put 2x 8gb (Corsair) in one channel and then put a single stick 8gb Crucial in the other channel by itself. (3 sticks total)
