I have a jtagged xenon that is getting the RROD(0020), it began freezing until it wouldn't start anymore. I believe this has to do with the bottom ram chips because I had it working for about a week by placing a piece of tape on 2 of them. I also installed an extra fan & souped up the stocks to full before it quit. I believe that the little pressure had made a connection on probably a cold solder joint underneath the ram. Now I could totally be off and it could be the GPU but I have a feeling it's the ram. I just wanted some more opinions on what it might be & the best way (besides reballing) that might fix it. I've already tried cleaning and applying thermal paste to the gpu & also running some alcohol underneath the ram. I'm trying to get this to keep running or at least until I can get my hands on a slim for the rgh.
Thanks in advanced.
