DDR4 memory issues Vengeance 3000Mhz

[Incompatible]

Hello,

This is my first post here as a new member and I really want to ask for your help.
I have the following setup:

i7-6700k @4.5Ghz
GTX 1070
16 Gb DDR4 Vengeance LPX 3000 Mhz


And I recently noticed that my ram runs at 2133 Mhz instead of 3000Mhz. I tried to enable the XMP profile in the BIOS ( Asus Z170 Pro gaming) but the computer refuse to start. So I decided to try with 2666Mhz at the same XMP settings and it worked. Now I would like to ask you if everything seems ok according to you. I would like to keep it that way and run with 2666Mhz instead. I lowered the initial DRAM voltage from 1.35 to 1.280 and so far no issues. I also lowered the voltage slightly for VCCIO and VCCSA. I'm running BIOS verion 2003 and would rather avoid to FLASH my BIOS since I don't feel comfortable with it.






Thank you!

Try setting the voltage to 1.4v and set the XMP profile at 3000 MHz

try slot a2 and b2 the traces should be shorter to the cpu and ram should be a lot more stable
