I believe I've just broken a world record.
I believe I've just broken a world record.
I purchased a used Xeon E5 2670 with eight cores and sixteen threads to extract samples for testing. Without applying any chemicals or sandpaper, I successfully divided the die layer—just a few microns thick—into two separate dies. I then selected two CPU dies in the time it would take to delaminate an entire Xeon. This feat is impressive; you can confirm no chemical treatment was used since the package retained its original green color. The presence of cracks and slight tarnish indicates I performed a straightforward brute-force extraction, without any sanding or abrasive work.
It seems your E5-2690 processors are quite similar across your setups.
