Ok guys Some pics from when I did this mod, My 360 was dead wouldn't boot. After doing this mod and applying heat it has worked perfect since..
Bear in mind I was happy to try this mod had no warranty, Didn't want to try the x-clamps first in case it didn't work after all the effort. I am personally gonna try x-clamp replacement 2 when rjbtech has an updated guide for it. This mod (penny trick) is for the in between and hey if it keeps working I may just leave it like this..
Thanks to kidderboots for the idea, Just changed it slightly..
Ok you will need
A roll of electrical tape
8 or 12 pennies depending on how much pressure you want to apply (I used 8)
Kit to open an xbox360
I was getting these freezing crashes, With a nice checkered pattern and crackling sound effect to go with it.
After a these crashes became more frequent eventually it would no longer boot up just red lights of death
So what to do is get your self some electrical tape and some pennies I used 8 pennies = 2 pennies for each replacement thermal pad for the ram
So cut the electrical tape long enough to wrap around the pennies. I wrapped 2 bits of tape around each twice
When you have your 4 replacement pads, Double up some tape i.e so its sticky both sides then attach them to your motherboard
When you have finished that re assemble your xbox360. Put back all of the screws including the gpu and cpu heatsink (x-clamp) screws and do them all up nice and tight
When you have fully re asembled your xbox360 try starting it up. If it doesnt work and you still have 3 red lights don't worry (yet). This is when you need to apply heat, I used towel trick for 18 mins.
And then hey presto its working again!
