So, I read from several sources that you could not de-lid AMD CPUs.
Mostly because they were all soldered.
Reading this, I decided to take an old, broken Athlon II CPU. Which was specifically labled asthe die being soldered onto the IHS.
As you can see. Athlon II CPU IHS. Surely the die came off with it, when I removed it, correct?
Wrong. As you can see. The Dye is perfectly in tact. And AMD used just as crappy Thermal paste as Intel uses.
Yes, I know the outside of the CPU is destroyed. I didnt have a razor blade, so I used pliers.
That's terrible. Even if it was broken to begin with, that's terrifying.
Neat info, though. +1 rep, if we had a rep system, which we don't.
Makes you wonder if the 8 series uses "Solder" as well.
perhaps that's the problem... maybe logan and pistol can try this on her 8350... the right way....
nope, fx series is soldered

Well darn. At least older AMD chips can be de-lid.
Well anyway, the IHS on AMD is like, 1/4 inch thick. If it were sanded down to half that, im sure it would run cooler than it does. Extreme lapping.
i know the apus are not soldered, but i've seen delided fx cpu's, half the silicon on the base, half on the heatspreader, looks pretty neat though
ehhhh... the thermal conductivity of solid metal is high enough that the IHS is largely irrelevant, as far as thermal conduction goes...
Well with a solid piece like that, the thinner it is, then the faster the heat would transfer, and the faster it would be taken away, that's why Direct die cooling is so much more efficient. Some people say it's the paste, but you have to use paste for direct cooling, so it's definitely the amount of metal.
But at least we know that, with slightly older AMD CPUs, they arent all soldered, and need to be de-lid.
