New computer is as follows:

Intel Core i7-7700K Kaby Lake Quad-Core 4.2 GHz LGA 1151 91W BX80677I77700K Desktop Processor

1 x Intel Core i7-7700K Kaby Lake Quad-Core 4.2 GHz LGA 1151 91W BX80677I77700K Desktop Processor
ASUS ROG STRIX Z270F GAMING LGA 1151 Intel Z270 HDMI SATA 6Gb/s USB 3.1 ATX Motherboards - Intel

G.SKILL TridentZ RGB Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3866 (PC4 30900) Intel Z270 / Z370 Desktop Memory Model F4-3866C18D-16GTZR

1 x G.SKILL TridentZ RGB Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3866 (PC4 30900) Intel Z270 / Z370 Desktop ...
EVGA GeForce GTX 1080 Ti FE DirectX 12 11G-P4-6390-KR 11GB 352-Bit GDDR5X PCI Express 3.0 SLI Support FOUNDERS EDITION Video Card

1 x EVGA GeForce GTX 1080 Ti FE DirectX 12 11G-P4-6390-KR 11GB 352-Bit GDDR5X PCI Express 3.0 SLI

Anytime I put the bios in XMP mode or even if I change the ram to 3866 with the rest of its settings that it should be at it either wont boot at all (like nothing have to restart pc with hard reset in order to get it to boot as BIOS recognized it couldnt boot and goes back to a previous good state). Not sure what else to do at this point..I'm pretty sure its the memory though because anytime i mess with the memory settings it dies...can anyone give me some good steps to take to confirm to see if I need to send memory back?

Thanks~

You dont have to run memory from the QVL,
Try keying in the primary timings and voltage that the XMP profile uses and leave secondary and tertiary timings on auto.
I don't think any of my systems are running "qualified" ram at the moment.

It explains the 'OC' notation in the board specs. Thank you for the correction. You would think it auto loads the settings in the bios once you click the xmp profile, but I guess not. I'm gonna look into my own ram timings as it also runs slightly slower than advertised.

OK I will give this a shot.
