Stupid, stupid, stupid. Most rma instructions tell you to only send the motherboard, not the accessories. Only exception is for a complete oem system (dell, acer, etc). They usually require you to send the whole box.
Just remember there's a chance you don't get your "accessories" back - and that's a biggie. It shouldn't be a big deal if you do it carefully, although with stock coolers I guess that gray stuff may make it stick to the heatsink..
well ***, i was packing up my mother board for rma, when i noticed a bit of thermal paste on the ram traces.
since all my problems were leading back to my memory controller, and or bad ram (although my ram was good) i tried cleaning it up, and bam seems to be stable as can be! saved asus a few bucks today i think, ill give it a few days see if it stays stable.
