This data can be read by putting the CPU into a proprietary reader in an AMD facility."
In case you didn't know this is how Odometers in cars work (since modifying it is illegal), among various other technology such as BlackBoxes. In fact, it's really very common in our day of electronics. Unless you thought that Warranty Void warning in OverDrive and CCC was a joke of course...
Get the 280x that has the 780 Toxic's cooler on it. Should be "nVidia" enough.
the only time you need warranty is when its broke, can they still read that data when the chip is killed from overclocking?!
also why do many people RMA stuff that they killed from overclocking, and still get a return?!

I also have a Swiftech H220 that would also have to perfectly flat to mate up with the FX 8350. What type lapping material would be used for the copper contact plate?
Please forgive me for my ignorance - through years of experience I have learned to ask someone who been successful at the task at hand!
Thanks in advance for any help,
No way is my lapping professional or any good.
if you have the right tools at your disposal then id use them, I guess you could get micron precise with how truly flat you want it.
I only used wet and dry, went from 400 grit to about 2500. used methylated spirit for the rubbing compound, some articles say gun-oil but I wanted something thatll evaporate. all done on a glass surface.
to protect the pins I used the plastic case the chip came in, cut in half.
there are loads of how-to articles on the net, read a few of them, practice on something else first and then youll find your own safe method on how to do it.Edited by d1nky - 11/18/13 at 12:25pm
