Pros: it's big sticks and compatible with Ryzen

Cons: One of my sticks is defective and refuses to run at 3200, the rated clock speed.

Overall Review: So i spent like 10 hours trying to get my ram running at 3200. XMP profile for my (msi x570-a pro) board (yes bios is updated) basically stops my mobo from posting whatsoever (cmos reset is then required). (ryzen 3900x) I have also tried manually tweaking, in addition to upping the voltage to 1.36 just in case that helped. It didn't... But when i go down to a single stick, one of them works at 3200 and the other causes nearly instantaneous crashes... I guess i need to return these?
