Memory upgrade.

I have two machines under my desk. Both have ASUS Sabertooth Z170 Mark 1 motherboards with 4GHz i7's and 16GB of RAM in each. I want to increase the RAM as I've noticed tasks showing waiting for memory status (rarely but often enough that I noticed). I've looked for the modules listed in the user guide and have not found them. Will any 288 pin DDR4 3400 MHz do, or is there more to it than that?
 
That board only supports 2133 and 2400 mhz ram. You really need to get more sticks of the existing ram that is already there. Have you checked the ram usage using task manager? What are you doing that uses up all your ram? Do you have programs running at bootup that don't need to be? Those can use a lot of ram as well.
 
The "spec" I used is a direct copy from the user guide that comes with the board. I have it on my desk, and just read the spec again. First item on the list, page 1-12 "DDR4 3400 (OC)) MHz capability" there is only one piece listed under that heading "CORSAIR CMD16GX4M4B3400C16". That is why I asked about sticks of that type.

>>> Do you have programs running at bootup

Yes.

>>> that don't need to be?

No. The systems are both BOINC number crunchers. The World Community Grid sub-project "Africa Rainfall Project 7.32" is the subproject under that umbrella project that has the high resource stats, from the sub-project choice menu, it does have a note about being sure if you want to connect with that particular sub-project. It has had that project enabled since the start, more than a year ago from memory.

*** EDIT ***
Belarc does not give the spec of the installed memory, only the capacity.

You can use something like CPU-Z to pull info off of the sticks, or you could manually take a look see.

I'd just match whatever's already in there.

I just tried to run CPU-Z, it looks like it needs an update, I've not run it for a while, (years probably), I'll have a play later, my girl is home now, so I am required to help cooking dinner. My plan was to move the two sticks from one machine to the other, and fill the first machine with new sticks, the part I was looking at looked like the best.
 
CPU-Z memory tab figures only...
1069.0 MHz <--- varies a little
3:32
15.0
15
15
36
278
2T

The DRAM frequency varies between 1068.5 and 1070.0. At the top of the screen, the uncore frequency also varies 4108.0 up to 4113.0, Makes me wonder if the frequency of the RAM is unimportant, it is the clock frequency divided by ~four...

Your board only supports natively up to 2400mhz. Up to 3000mhz as an overclock only If you don't edit the ram frequency and timings in the bios manually then the ram will only run at 2400mhz.

I'm pretty sure you are running 2133mhz.

Open cpuz, click on the spd tab. The part number section tells you the specific ram that is in your pc right now.

If it's like any of the other Intel boards out there for the past decade... ram overclock really only consists of flipping a switch in the bios to enable the XMP profile of the ram.

I looked at the manual, did not see the xmp setting so he will have to manually adjust frequency and timings.

Nah, there's no way XMP is not an option on a Z series chipset mobo. Especially on an Asus board. That Asus UEFI UI should have the XMP settings in the AI Tweaker page, and should be set under the AI Overclock Tuner row. If the Z170's bios is anything like my Z390's bios layout, that drop down would have Auto, Manual, XMP1, and XMP2.

You are right. Did not see that as I was skimming it. He should be good then.
