I really don't understand what my north american brothers don't undertood.
Well, it work so:
The memory units are really close of a awesome 3-core processor and a excelent GPU. So, it's obvios that the temperature in that area will go high.
With the high temperatures the material used to (alguém que fala português traduz ai pros caras a palavra SOLDA, pois eu esqueci!!! hehehe) SOLDAR the memory will dilatate (se os caras não entenderem, dilatar).
The memory, with his own weight, whi be pushed down, in some time, the contact between memory and mobo will be interrupted, then... 3RL.
The eraser will mantain the memory unit in contact with the motherboard, this is the trick!!! Because this the trick works, its nothing about memory temperature, but CPU and GPU. But, if anyone could use a heatsink instead of a eraser, cool, it will do the trick and help with the temperature problem.
Anyone can try this trick... will work, and why will work? It's just above!!
Abraços ao colegas brasileiros...
Cheers!
