Maybe get some more experiance befor trying to fix a problem you can't help with.  

I have experience but I couldn't find the manual you were referring to and the mobo I have has NVME in one slot and sata in the other so that was my first idea I had in mind

Literally first entry when googled...

Sometimes with a question that has languished for a longtime unanswered it is nice to simply know that one is heard.  The whole “you do not deserve to try and help” thing has the problem of both dissuading people from receiving replies and promoting elitism which is not a useful purpose.  If posts receive no replies people can assume the forum is useless.  

Yes but wildly guessing is also not helpfull. Also I think a post is more likely to get klickt when there are no answer. At least for me. Also agree elitism is not useful but so is clustering up a thread. 

That is not the result I get tho I get where I can buy it they do have manuals there but it doesn't say the same as the image you sent (why even argue about this it's just such a stupid thing to argue about)

@djboy6480 I sort of assumed it depended on how old it was.  It depends on how long someone is willing to wait to get information.  There are people here who know a heck of a lot about computers and people who know little.  The problem is there aren’t all that many knowledgable people and there are more questioners  than answerers. Elitism was the problem with OC fourm.  Things languish for days there.  Answering wrong is of course still always bad
