EVGA Z370 FTW XMP not working. I had the same problem. CPU 8086K and G Skill Ripsaw XMP 32GB (4x8) 3600Mhz. My ram is not listed and doesn't mean it doesn't work. EVGA can't test every single ram stick or sets being manufactured.
I can run the ram with XMP on and manually change only the speed from 3600 to 2800 with everything else set to auto on my motherboard. Anything higher than 2800, my motherboard would not post. So below are the steps I took to get the ram up to 3400 speed which is fine for me for right now.
These are the 2 simple settings that I needed to adjust to get my ram running faster than 2800. 1) CPU I had to overclock multiplier to at least 4.5 Ghz with AVX set to 0 for now.
UPDATE: I was able to go to 4.7 and using 2 AVX offset for now.
2) CPU I set my VCore voltage to 1.248 (for an 8700 I think you may have to go higher)
UPDATE: I was able to go down on my VCore to 1.150 for 8086K
3) CPU I set Vdroop to disable (It should always be disabled)
4) Other Voltages VSA between 1.050 - 1.150 . Mine works at 1.100 and VCCIO between 0.950 - 1.050 mine works at 1.000
NOTE: The motherboard will run the voltage you set a little bit higher if needed. Check it with CPUID HWMonitor that is free.
5) Memory selected XMP and everything should populate automatically. Save and reboot. It will take about 1 minute for the bios to go thru their cycle testing since it's not the normal ram speed of 2133. If the 3600 speed doesn't post, reset you bios again by clicking red button above the rear USB ports not inside the case. Click it once and do not hold it down. Motherboard will reboot twice, then goes to a screen with text, select F12 to get back into Bios. Follow steps 1 thru 3 again since it puts everything back to default setting. This time select XMP settings, change the default 3600 speed to the next setting lower like 3400 save and reset. Remember, the Bios will take about 1 minute to go thru its cycle. If it doesn't post, go thru everything and set the XMP to 3200 to see where the thresh hold might be for the above CPU and voltage settings. Use CPU-Z software that is free to view your CPU and RAM info.
XMP NOTE: Make sure to check the voltages above once you have select XMP because your XMP profile may change the voltages above if they are left to auto. So check before you reboot.
If above didn't work you may need to increase the following1) CPU VCore voltage from 1.248 to 1.25, 1.255 etc. in small increments
UPDATE: Was able to go down on my VCore 1.15 for 8086K
2) If needed CPU overclock multiplier from 4.5 to 4.6 Mhz (I don't think you need to go any higher but you can)
3) Don't forget the Ram XMP speed
Once you get everything working, now you can go back and start lowering your voltages for VCore, VSA and VCCIO until it doesn't boot and then go back and increase it to find the perfect settings. Keep good notes or take pictures with your phone of the setting you’re doing while making these adjustments. The lower the voltage, the cooler your system will run by far.
It took me about a good 1-2 hours to finally get my ram to boot at 3400 which was fine with me for now and better than the 2800 speed.
RAM NOTE from the manufacturers that many people don't know.I did buy two packs of G Skill Ripsaw 16GB (2x8) XMP 3600 MHz to get 32GB of ram. But if you do buy two separate packs to get 32GB of ram, the ram manufacture can't guarantee that it will work at 3600Mhz speed since it was not purchased as a 32GB (4x8) pack. With that being said, with the two different packs of 16GB may use different chips in them and may not work together properly. But I was able to get mine I've purchased to go to 3400Mhz speed. I'm fine with that for now.
Hopefully this helps because it worked for me and the Motherboard or Ram manufacture can't tell you what to change as in voltage or overclocking.
