I know this has been posted a number of times in the forums. I couldn't find anything on the search function. I don't know why. I did Google for information, but I'd like to get a reply here @ the X-S forums instead.
I don't have the original 360 metal chassis, so my setup is this:
M5 Screw = Motherboard = Nylon Washer = Metal Washer
Is this a safe setup? I'll be doing an ATX Power Supply mod, so I'd like to be on the safe side just in case.
Is this in regards to an X-clamp fix or bolting down the board for a reflow? I'm gonna use my reasoning and say its the former.
If you ask me, put the X-clamps back on. Those bolts don't do anything but damage the 360 further. Unless you are flat broke and can't afford a reflow or reball, fixing RROD with those bolts should never be attempted. If your 360 hasn't RROD'd yet, put the clamps back on. The bolts can put too much pressure on the chips, causing them to crack or for solder balls to be crushed. The motherboard can warp around the bolts making a future repair next to impossible. With x-clamps, pressure is even and fairly safe, which is why Microsoft's engineers never took them out of the design even when they were correcting issues that led to RROD.
But if you must use bolts, use a uniclamp design. If you don't care about potential damage just go M5 screw = nylon washer = motherboard = nylon washer = metal washer. But remember, nylon will compact over time from the pressure of the screws. So you might want to replace those washers in the future...
