To determine if a processor is an engineering sample, refer to the processor markings. The Q-spec (a four-digit or five-digit code) will begin with the letter 'Q' instead of the standard letter 'S' which is used for production processors. Engineering Sample processors may also have the words ES located after the Q-spec or the words INTEL CONFIDENTIAL marked on them.
Engineering samples are not supported by Intel Customer Support and are not eligible for warranty service.
If you have received an engineering sample processor from a vendor, and you would like a production processor, contact your vendor for replacement information.
