Yeah Raja said it means memory, cpu, or one of my blocks is too tight.
I've since removed all the blocks from my board and put the stock heatsinks back. I don't have a 2011 air cooler, so still have my supremacy on there but i've reseated it a bunch of times already. Plus i don't think it's really possible to overtighten a Supremacy
I've checked the socket, and there's nothing that i can see, but it can be tough to notice a bent pin in a 2011 socket. Especially since lights kinda play tricks on your eyes with all the little pins. I got off the phone with Asus support like 15 minutes ago, so my RMA is filed. Just waiting for the email. I'll be taking some macro pics of the socket with good lighting and a tripod before i pack up my mobo for sure.
I looked at the cpu itself too. I don't know what i was looking for since it's not de-lidded or anything. It LOOKED fine tho. I'm worried because i broke my 3rd GPU slot locking lever a while back, and while i could care less if they fix it or not, it makes me look like a reckless consumer.
The support guy on the phone said rma should take a week to 10 days. But everybody complains about Asus RMA, so i don't know if i should believe that. If it's gonna be weeks to a month or more, i should just grab that x79 extreme6 to hold me over.
