If the base clock was upped, then it will also affect the memory so once you enabled XMP it was too much for it to handle. Typically the best approach is to only change multipliers and voltages unless you are more experienced to tweak deeper to inch out every tiny bit (likely only noticed in benchmarks).
Plus i believe changing the base clock has a greater chance of reducing the life of the CPU and possibly mobo, ram, and anything else it affects. A stable OC with multiplier and no insane voltages only shouldn't reduce the life noticeably if at all.


Appreciate the info. I have a few more questions while I'm at it. The option "DRAM Reference Clock" is set to "Auto", but I also have a "100mhz" and 133mhz" option. Is auto what it should be set to? Also would it be a good idea to enable my "Memory Fast Boost" option, or keep it at Auto? Lastly, under the "DRAM Frequency" option is a drop down list which has memory speeds up to 4133. Seeing as my MOBO can go alot higher then my 2800mhz advertised speeds, would I be able to slowly go higher up that list to see how fast I can go, or is it ment to be set to the exact speed that I have? I've included a few screen shots to show what I mean in case the way I worded things are confusing. Sorry for the barrage of questions, but you guys are helping me learn alot. Thanks again!

I unfortunately don't have any experience with recent CPUs to overclock so I am not able to confidently answer those questions, but I will give a few opinions until someone can better chime in.
You may benefit from finding a thread on Z170 overclocking in general and read that or ask some questions these too if not much is explained here.

I have never tried to OC my RAM as I don't believe it really does many noticeable things for everyday and gaming use, maybe a few FPS at best. I just didn't want to commit the time to the repetitive OCing process, but maybe someday I will.
I just bought a quality set of 1600 speed DDR3 for price/performance and set the XMP profile and never touched it since (going on 3 years now i believe).
In my opinion you are better off leaving the RAM at the XMP profile and then doing a CPU OC and call it good, but if you want to tinker and learn more then its fine to read up first on RAM OCs and go from there.
By using an XMP profile, that will certainly keep your DRAM Frequency at the rated 2800 and likely you will want to or have to keep the DRAM Reference Clock on Auto as well.
I am not sure what the Memory Fast Boost is but it might just be a quicker boot into the OS if you are using Win8 or Win10.

Going back to the DRAM Reference Clock, I think the 133mhz is where it will be a lot harder to keep stable or force you to use higher timings so 100mhz is probably the one to use if OCing the memory for normal use, but again I dont know for sure and especially when it comes to DDR4.

Good Input! Ocing is like addicting to me in a way. It's like well I did my CPU, now the ram, but lets see if I can go just a little higher...then a little more...lol. I've been able to get 4.4Ghz steady so far, but anything above that seems to give a BSOD after awhile. This is unsettling seeing before the XMP I had 4.6ghz stable with even more room to go. I guess my next step would be to up the base clock? I believe its a voltage problem. I'm running 4.4ghz at 1.3V, not bad right?

1) Leave memory fast boot as-is (auto)
2) No, just because your mobo shows it can set 4133 RAM doesn't mean you can use that, it's for sticks rated for that speed and/or when you're running stupid voltage. eg. my 3200 @ 1.35v need 1.39v to be stable at 3333, so a minor bump.
3) DRAM reference, again leave this to auto. I'd think it was 133 already. I've only seen one screen-shot of someone running at 100. Download memtweakit as an eaxmple, I believe the "mode" there shows what you're running (100 or 133). I don't think I can even change that and mine is 133.

Anyhow, go to the Skylake OC threat on the intel forum and you'll find how to set / how to test things.

Sounds good. The dude above me said "100mhz" for the reference, but you say I should keep it at "auto", should I just keep it at auto where it was?
