    Verify 3920XM is legit?

    So my 3920XM finally arrived today and i connected it right away, the CPU-Z says its a ES Version. Serial Number is QC7R but isnt that a QS version?
    anyway it clocks to 3.6 ghz on stock across all cores so I guess everything is alright? temps are fine aswell, never go beyond 75°

    Is this the real deal (QS) or is it a ES?

    CPU-Z will still show ES, even if it's QS.

    QS is a final, more stable version of ES.

    If "QC7R" was written on the processor, it's a QS.

    Final shipping silicon was E1 stepping so it looks like you have final generation ES rather than QS.

    That or the QS served as the final ES and they made another minor revision for retail.

    What does HWinfo say under CPU - Production Type?

    It says QS for the serial number and the Type is a Engineering sample (ES) Whats worrying me is that Original Processor frequency is only 3.1 GHz

    what do I do?

    Meaker, the guy I bought it from also has the QC22 and QB2U version, are those any "better" e.g. closer to OEM? or better stepping in this case
    what is stepping anyway and should i worry about it?

    Hmm, well stepping for otherwise is E1 but typically the numerical value only denotes minor changes.

    Why? Production units base frequency is 2.9 GHz. The CPUID and QDF don't match up with the production unit specs either, so as far as I can tell, it looks legit.

    Stepping is basically the version/revision of the architecture. A2 - A3 would denote a minor production change, while A3 - B0 denotes a significant change.

    ok thanks alot, you guys are awesome I wouldnt have found this anywhere else just by googling.

    so i shouldnt bother trying to get a E1 version if this one works fine clock and heatwise?

    No, all the chips we used to be able to find were all ES, and then Intel changed the name to QS. He has a QS.
