i am a bit surprised myself to be honest..
 
It seem like everything just is running extremely well tuned..
 
I cant take all the credit myself, i suspect the motherboard is very good when it comes to response time and stability / output
 
less things on the PCB is always a good thing when it comes to performance FTW
 
i did notice however that the motherboard for some reason sets the tWCL a step or two higher than the CL by default, and that's wrong (and will degrade the performance very much)
 
Keep tWCL one or two steps lower than the CL instead for everyday use on DDR4, and in this bios you need to be aware of the offset, if you set tWCL 15 its actually 14 in real life Z170 FTW..
 
so 3200mhz CL 15 / tWCL 15  (14) = good 24/7
 
3200mhz CL 15 / tWCL 14 (13)  (consume more DRAM voltage to be stable, but with a minor gain in latency)
 
There is no reason to go lower than 2 steps on DDR4 using CR 2, the small gain wont be worth it anyway  (stability issues, higher voltage and so on), and performance degradation soon starts to kick in
 
All the kits i have tested have worked like a charm at 3200mhz with this board (manual custom settings, max 1,32v in bios / 2133-2666mhz XMP kits), Crucial kits have not reached that high  (known fact, but they can run silly tight instead at lower mhz)
 
+3300mhz also works for most the kits i have tested, but my Hynix based predator kit seem to thrive at around 3200mhz CL15 for 24/7 use
 
haven't tested XMP yet tho..
 
I have not browsed this forum very much to be honest, but i have a feeling there should be a manual memory OC setup guide in here somewhere, check that one out if you are having problems getting your kits run at higher freq and faster than your dedicated XMP profiles, gaming stutter problems, instability, low performance etc.
 
Buy lower speed rated XMP kits and OC them yourselves instead, y'all would be surprised how fast the kits really are..... bang for the buck  2400mhz---> +3200mhz no problem
 
FTW
 
 
 
 
 

in this thread i had problems with controlling the cpu fan speed
 
1000 views in this thread
 
Could not even a mod have told my that its possible to edit the fan curves, -->"hey just click there, and its done"
 
By mistake i accidentally found the tab for this in bios
 
So the pwm adapters i have made was clearly in vain.. for nothing
 
Its my first EVGA motherboards, but i guess it was fun to watch the missilery..
 
i cant even find the words.......
 
 
 

XMP my friend is far the best option.. the XMP is a OC also, the only difference is that its not made by you..
 
2133mhz is also a DDR4 OC
 
 
If i enable the xmp profile i think the memory performance would drop with 30% or so.. and also the overall system performance in benchmarks / games
 
My XMP is 2666mhz,  my default setting is 3400mhz
 
XMP is very handy for people that's not into tweaking, some people just want a every day computer that works fine every time its powered up..
 
Bad memory OC on the other hand will drop the performance, just like a Mallard hit in the head with a shotty
 
get 2400mhz XMP DDR4 and OC them instead and save a buck  2400mhz--> 3400mhz (and pick up some knowledge along the way)

Actually the XMP profiles have about 30 settings o speed you can use for mine on the ripjaws, I have went to 2800 I see no improvement from that compared to my 3200 I am currently running which runs better than the 2800 settings.
 
 
Test my friend would be great but my work season starting and I will be about non existing around here more than likely till next winter I was trying so hard to get some hours in to qualify for the 980ti give away on evga servers I got the email like way late, so I guess I'm out of that as well sighs super sighs never won nothing but a dang free lottery scratch off in my life and way to poor to buy better cards lol. I went in debt on this system but had to build my old 780I FTW rig bit the dust lasted almost 10yrs, had a 680i for a bit in it.
 
PS if you have time and notice anything let me know PM please because I live in the deep south very low income here and work solo as a landscaper/lawncare it's brutal and the avg income around here is like 25k a yr.
 
But if the ram takes damage GSkill is lifetime covered so thats g2g lol
