So i had a problem where I tried to oc my ram after doing so (lots and lots of failed attempts using the calculator for ryzen) i found one that didn't crash however when i tried to load into widows i got stuck on auto repair boot loop cleared cmos then tried again (for those of you who know how long and hard it is to go threw all the timmings you get my pain) to no avail sat on forums for hours. heres the weird part i found 1 dim slot would work with both ram on xmp but together would not after i had been using xmp since i built my setup. i tried it all flash bios, renistall bios, mess with ddrv, litterally everything you can imagine. But then i came across a form that said that your aio pump after being on for a while can come loose or sag on one side causing some pins not to connect, i thought to my self surely this cant be true, even if so this wasn't a problem till i started overclocking my ram so me being desperate i completely dissembled my board gpu, ram, m.2, checked all connecters 24 pin 8 pin and finally tore down my aio and cpu and check to make sure i didnt bend a pin thank god they all looked straight to the naked eye so i put her back in reapplied the thermal paste and remounted my aio which can be very confusing for new builder or to old ones who just wanted to try amd as most of the mounting options really suck lol unlike intels always sturdy 4 screw bracket i have two thub screws that pull up on the two flat pieces. checked temps posted great first try then i checked speed stock 1333 then i tried xmp again and wah la running at 3600 speed. so a quick guide if your having memory issues step by step 1. clear cmos try again 2. flash bios 3. try different ram (if you only have one test each one in the 2nd slot or 1st deppending on your MB) try each one with XMP on and off if one doesn't work then there you go bad ram if both don't work try different ram 3. try a different MB you can easily fry the dim slots over volting 4. uninstall and reinstall your cpu 5. if still no luck its possible you bent a pin on your cpu or its fried. good luck OCers
