Again, there are no manual settings specific to the kit, you would have to change them to see what works for you.

Well help then. I need the full specs for the ram to manually plug into the bios to run at 3000. timings, voltages.

It definitely shouldn't have an issue with it.

It ONLY hangs when XMP is used. I need to know if this memory will work XMP or not with this board. If not I will return for a cheaper set.

If the computer does hang, a replacement would be best.

Bios version 3007 dated 11/29/19. I've noticed on your support forums that a lot of people are having problems with XMP settings on Z170 boards, but some have success by manually putting in the XMS profile.

 

Also the memory passes memtest running 4 hours at the slower default setting of 2133.

There are no specific manual settings, unfortunately. Which bios version do you have installed?

You can get the original XMP timings for your kit from Aida64 > Motherboard > SPD.

 

Edit: If those don't work, you can try my settings:

CL15

Keep command rate at 2T until your first stability tests passed successfully. These timings are still @ AUTO mostly, i just manually set a few of the problematic ones. Since you did not state the actual model number of your kit, if it is a 2x16GB or 2x8GB single sided variant, you probably need to raise/double the tRFC (my kit was CMK16GX4M4A2800C16, so 4x4GB). For voltage start with a Vdimm of 1.35V, then try lower if fully stable.

My 6700K an M8G could do DDR4-3000 with VCCSA 1.096V and VCCIO 1.040V, but what is actually needed varies from one CPU to another and the MB also plays a role in that. From Rajas statement here, you will probably need a bit more VCCSA and/or VCCIO because of your "mainstream" board.

 

Yeah, I love how before it was released, it wasn't so "mainstream". *groan*
