Here's a bit of a shocker.
Iv been doing a new CPU modification never seen before (to be uploaded to the GHETTO THREAD)), but this is not the reason why I'm posting in this old thread.
Every time I change the Liquid Metal Compound I use a brillo pad to scrub the surface of the CPU core. With the new modification in place I'm thinking I have broken the the CPU as there is a strange reading to ground from the heatsink. I was then thinking part of the modification is shorting to the IHS..
After a long check I found the CPU core, the part where all of us put our thermal paste has become conductive, ie it's out putting 21.2mv. I did not know this part can become conductive. I check three other CPUs, it's not conductive,. So it looks like if you lap the core it will become conductive. at some point, at lease it does here on a single CPU.
