DD TDX and AMD64
 

I have both of these things on order (I got the CPU tonight) and I was wondering if the tdx will cover then entire chip. Does it need to? Is that big silver thing just a heat spreader?

The TDX does not cover the entire 2500 mm^2 of the CPU but that's ok; the only important part is where the core is located, and a few millimeters around it. The core is roughly 10 by 12 mm, and is centered. Heatspreader or not, the same applies.

It might seem cheap for DangerDen to do this, but there's no real need for all that extra copper anyways, so if it cuts costs, it's all good. ;)

I would imagine they'd be doing it for looks - milling the blocks to shape would be pretty hard on machine time + the mill bits (but then they will be machining on borrowed time, so i guess its moot - i doubt its entirely for cost saving though)

Okay, I was just wondering. :)
