base on the Picture Above

1) what does "CL" mean?
-Higher better ? lower Better ?
2) 2400 Stands for Frequency right ?
- what does Frequency do ? Higher Faster?



This is my Mobo Frequencies

3) Will the 2400 Memory Frequency Run with my Board ?
-2800 vs 2400 Which is better


Thanks in advance

The CL is a metric of the memory's timings. It is not too important for your case.

Frequency is simply the speed the memory runs at. Higher allows for faster data transfer speeds.

The 2400 and 2800 memory will run on your board. All you have to do once you install the memory is to go into your BIOS and enable the XMP profile for it. It will automatically adjust all of the information needed.

Just a little more info due to problems that I (and others) have had, particularly with Z170 boards and Skylake processors. When your computer first boots up, the memory will be running at 2133 MHz (the default for the motherboard). You can confirm this on the BIOS screen.

After enabling XMP, you might get a black screen, that is, XMP didn't work. Just reset the BIOS defaults for the motherboard. Your manual should tell you how to do it. You probably will just need to clear the CMOS.

Hopefully, that won't happen. But it did to me on several Z170 boards, both ASUS and Gigabyte. Worst case: your memory will run fine at 2133, and you won't notice much difference if any.

the instructions are not finished sir
when i clear CMOS
which will return all in default
Which means i will not be able to Run mg 2400 Memory ?
or Should i Enable XMP again and it will work the 2nd time ?

No, it probably won't work trying XMP the 2nd time. But it will work just fine leaving it running at 2133.
BIOS updates might help with the XMP. You can also mess around with memory voltages and other parameters, but I wouldn't do it unless you really know what you're doing--isn't worth the effort. But as long as clearing CMOS to return to the defaults works (which it should), you can always keep trying things.

The memory will run at 2133MHz. Notice in your memory's specs that it's SPD is 2133MHZ (that's its default, just like the Z170 motherboards). Your memory is built to run at 2800MHz when XPM is set, which hopefully will work. If it doesn't, another option would be to manually set the memory's frequency to 2400, which is slower than 2800, but might work.

I missed that. I thought you had the 2800 memory that you showed above. If you're buying 2400 MHz memory, then that is what the XMP setting is supposed to give you. If it doesn't work, the defaults will run it at 2133 MHz.

Just as I said in the beginning: the memory will initially run at 2133. Then turn on XMP, and it should run at 2400. Or that might give you a black screen, which means it didn't work. Reset CMOS, and it will run at 2133.
