DDR4- 4000 Ram crashing games, Do I need to return it?

[Wojo-88]

My system:

OS: windows 10 pro 64

MB: Asrock 570x taichi (with latest bios)

CPU: 5950x

Ram: G.SKILL TridentZ RGB Series 32GB (4 x 8GB) 288-Pin DDR4 SDRAM DDR4 4000 (PC4 32000) 

SSD: Corsair Force MP600 M.2 2280 1TB PCI-Express Gen 4.0 x4 NVMe

GPU: msi nvidia 1070 (place holder edition)

 

So my RAM (https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820232973?Item=N82E16820232973) runs at 2133 hz and 1.200 v if I leave everything in " auto" settings in bios. If I enable XMP the settings change to 4000hz and 1.5v. At this setting the desktop loads and everything appears to work fine untill I try to load any game. All games start as normal and run up to the point of actually loading in. At that point I get fatal errors and crash to desktop. I tried to manually set the XMP settings and still have the same issue. This ram was not cheap! Is it deffective? Should I return it to Newegg before my return time is up? Or is there something I am missing? XMP is all new to me.

Thank you for any help,

maybe your mobo cannot handle it or your ram is defective

XMP profile might be unstable. Try manually setting the voltages. First try 3000MHz at 1.35V. If it is stable, I guess try further?

I had similar issue with my Corsair Vengeance 3000MHz 8x2GB config. being unstable. Most RAM modules should be able to hit 3000 at 1.35V
