Hello HyperX, I have a 2*8 GB kit of HyperX Predator RAM @ 3200 Mhz, and it does not want to work in OC with an XMP profile or even in OC with manual timings... I've never been able to do any OCs, despite the fact that the BIOS has changed....
I bought the new kit on Amazon.it via the Amazon seller (I live in France, and the kit comes from a French warehouse)

My config:
Ryzen 5 1600
Gigabyte GA-AB350 Gaming 3
RAM Hyper X Predator 2*8 GB @ 3200 Mhz

I also tested the RAMs via memtest x86 a few months ago, nothing to report depending on the software.
Tested 1 to 1, no OC/XMP possible (except in the following case, see paragraph below...)

4 months ago I wanted OC using only one of the two bars only (the other RAM bar was set aside), it went with the XMP profile at 3200 Mhz, the PC started correctly in 1 time, but once in video games (and in particular GTA 5), within 5 minutes the PC crashes (BSOD)

Do you have any idea where that might come from? I've tried a lot of things I think but nothing is getting better.....
I can give you more details about the events I described above in another message!

Thank you very much in advance, and have a good day.
Valentin
