Lapping the die is only recommeneded for the real XOC geeks, who need every last millihertz out of their CPUs for compatition.
Some come in trays(no packaging) and they are generally the ones cherry picked for delidding and "guaranteed XX MGHz.
Boxed ones are in official Intel packaging(in this case the blue hexagon).
Also:
A boxed intel processor vs. a tray - CPUs - Toms HardwareThere is no quality difference between retail (boxed) and OEM (tray) processors. The differences as you already said are a shorter warranty period and you have to get a CPU cooler separately. Since you don't intend to use the stock cooler included in the boxed version anyway there is no reason not to bother with the OEM version, unless you really, really want the three year warranty from Intel.
OEM versions are also generally sold for a lower price than the retail boxed version, part of the higher price for the retail versions covers the lengthier warranty period, as well as the stock cooler. OEM CPUs also tend to be more popular with overclockers, as overclocking mandates an aftermarket cooler, and overclocking also voids the warranty, so none of the additional benefits of the retail boxed version apply to those who intend to overclock their CPU.
You're welcome Mike.
Since this time I am not buying a delidded, I decided with a boxed(which is also sealed) version to take a chance on a really go overclocker, as Caseking, being an OEM has already picked out the good ones from the tray's, for their systems(they are also system builders) and delidded CPUs they sell, and if I ordered a un-delidded tray version, it probably OCs all cores only to Intel 9900K specs and not all cores to 5+ GHz.
