Hello everyone . My problem is next : I have ASRock AB350 Gaming K4 MB and HyperX Predator 2x4GB 3200Mhz CL16. When i went into my UEFI, i saw that my RAM was working on lower speed (2400) and higher latency (17), it was confusing to me. I don't know much about OC but on my motherboard it says: supported memory: 4DIMMs, up to 3200+(OC) for (Ryzen CPU). I have Ryzen 5 1600 and i don't understand why do my memory is working on lower standards. Anyways except that, i tried myself to OC it. There are XMP profiles and i picked XMP profile 1, which is 3200Mhz CL16,Other fields were automatically up by 1, (if i remember correctly 18,18,18,36) and 1.250V was 1.350V. I pressed Save & Exit, and i waited, then my PC started going wild... It starterted turning on for 1 sec then shutting down for 4sec, and it went on and on in loop, i was scared. I started moving my mouse and clicking it and it thankfully started booting, then i quickly went into UEFI to fix what i done, and i reverted all of the above to "auto" and my system worked perfectly. One more thing, when i booted my pc, after that long loop, i saw that my memory speed was still 2400Mhz. Sorry for the long post but any help is appreciated.
