I came across and i7 860 that was only the cpu itself and no box. The cpu has nothing on it stating what it is or anything like that. It hasn't been lapped or anything else.
Is the cpu an es or something else?

How would you know it's an i7 860 if it's got nothing labeled on it? lol

Hmmmmm, never seen an ES in person before... have you tried OCing it? I know ES chips tend to be golden batches, can clock really high with low VCore (correct me if I'm wrong)

Haven't messed with it much. Its sitting at 4.0 right now with 1.33 or close that if I remember right. Not at computer so not exactly sure. Not sure if that's good or bad. I haven't tried going higher since all its doing is folding bigadv. I might take that h70 off it and put a custom loop on it and see if it will go higher.

Hrmm.... for a golden batch usually the VCore should be around 1.2 - 1.23ish... at 4GHz I think...

If it has no markings on it, it clearly isn't intel retail certified, I reckon it is a ES

an engineering sample. If not then it probably was lapped

Lower the voltages on it, see if it remains stable

If there is nothing on the IHS of the cpu then the laser etching has been buffed off. This is common with thermal pastes that are abrasive like IC Diamond. It happens when you clean the paste off the CPU over the course of a few instalations. Even ES CPUs have markings on the IHS. And just to demystify engineering sample CPUs they are not all golden and overclock like crazy. Usually an engineering sample CPU is an early revision of the CPU that is sent to board manufacturers so they can start development of their hardware. Most ES CPUs are really no different than their retail counterparts, save for some of the notable "B0" core revsions that have an unlocked multi where the retail part may not. For instance I have an early B0 revision E6600 that has an unlocked multi. But these are extremely rare to find and the vast majority of ES CPUs as I said are really no different than retail. Also, retail CPUs are sold all the time without a heatsink. These are called "OEM" versions and are virtually identical to retail CPUs save for the lack of a heatsink and the retail box. They too will contain laser etching on the IHS identifying the CPU unless as I said it was buffed off with abrasive thermal paste. If you haven't yet, download CPU-Z and see if it tells you its an ES CPU. It will list it in the CPU name box with an "(ES)" following the CPU name. For instance if its a engineering sample CPU-Z will list as a "i7 860 (ES)" if it is. If not it will just list it as a "i7 860".

Simple if you wanna find out if it's ES. Boot up CPU-z, and post a SS here.

cpu-z shows nothing next to i7-860. I have taken a couple of pics of the cpu. The top of the cpu is very smooth like it has been lapped but there is no discoloration on the chip itself like it has. Is it possible to get a smooth surface from lapping without taking off the silver coloring on the cpu?

LoL, maybe they used too much ICD on it.

It's not an Engineering sample CPU. It's just simply as I said with regards to the use of IC Diamond buffing off the etching on the IHS.
