XMP causing instability

Sorry for any format issues, this is my first time posting here, just signed up.

 

My Rig:

i7 7700k 

msi gtx 1070 armor

asus z270a pro MB

and what's giving me problems: Corsair Vengeance LPX 3200 32gb (2x16) ddr4 memory sticks model : CMK32GX4M2B3200C16

 

for whatever reason whenever i try to turn on XMP my rig crashes under any intensive load and sometimes fails to boot at all, usually with an error code google says is related to memory. right now its running at 2140mhz , 15 - 15 - 15 -36 i think? pulled off of CPU-Z before this upgrade i was running a 16gb kit from adata that ran fine with xmp. any suggestions would be really appreciated. I'm mostly new to computer building and this is my first attempt in probably 6 or 7 years so I'm out of date.

 

thank you!

thank you!

Set your DRAM voltage to 1.4v, set your DRAM clock to 3200mhz. Leave timings on auto. Check if your system posts. If it doesn't, reset the cmos and raise the voltage up until 1.45v. If it does post, set your timings to something like 16-18-18-36 and run Cinebench R20 a couple of times to see if it's stable. If it is, work on lowering the voltage until it becomes unstable. If it isn't, raise your timings by 1-2 until you get the results you want.

How often is often enough? XMP works fine on my system.

I see plenty of topics around LTT having XMP issues. Enough for me to suggest people turn it off if they want a stable system.

 

NOTE: I no longer frequent this site. If you really need help, PM/DM me and my e.mail will alert me.

part of the problem I'm having is figuring out the overly complicated bios on this thing. if i can sort out enabling those data fields i will try this though thank you!
