You mean ones like this?http://cgi.ebay.com/SUPERCHARGED-985-NEW-Intel-Core-i7-950-965-975-Extreme_W0QQitemZ200425071365QQcmdZViewItemQQptZCPUs?hash=item2eaa43e305
Its a scam, OC results depend on all of the components in the system, and the CPU will not retain those settings as it has no permanent memory. Also if you look at the details, i would expect the CPUs to have an incredibly short lifespan
CPU Type: Core i7 (SUPERCHARGED 985)
CPU Socket Type: LGA1366 (X58)
Certified Speed: 4.3GHz @ 1.481v @ Up To 97°C
Cooling Used: 100% Air Cooled / Noctua NH-U12P (1366 / SE2)
Note the voltage needed and the temperature, they arent supposed to go over 70C, 97C you are well into the damage range, and that voltage is more than .1V over stock. He may have gotten them up to that level, but they are permanently scarred from it.
