    found it. QRG4 Plat 8260(B1) ES 24C 2.30Ghz 165W note there are other 8260: QPK5 Plat 8260(A0) QS 24C 2.30Ghz 165W DDR4-2933 QRB0 Plat 8260(B0) QS 24C 2.30Ghz 165W DDR4-2933 the QS will have the same stepping than the matching production unit. HWinfo shows B1/L1/R1 if the DIE size is not reported.

    unfortunaly NO. the BIOS does not allow SKL B0 because of security reasons.

    the AVX512 unit requires more core voltage, with 3 GHz the cpu would draw 300 Watts or more.

    some seller don't know what they sell. that is stepping A0 (50655) not B1 (50657) what is the QDF ? Q??? (printed on the Heatspreader)

    B1 is latest available stepping Cascade Lake XCC DIE, same than Xeon W-32xx have. L1 and R1 is the same but for other DIE sizes(HCC/LCC)

    QDF: QS?? specs looking similar to the QPKD(A0), but with better stepping B1. what is your CinebenchR20 score ?

    With the AVX-512, due to the double register width of 512-bit, one opcode can do eight additions with double precision or 16 additions with single precision per clock. programs written with avx512 code is faster and shorter, but (today) not very portable to other platforms/processors.

    normaly you are right. but cascade lake is a refresh, not a new platform like skylake was. AVX512 frq. will be much lower, there is bench in CPU-Z which uses AVX512 code, Cinebench R20 uses only AVX2.

    take a screenshot of the HWinfo processor section, there is a table of nonAVX,AVX2,AVX512 frequencies. sample

    QQ8Q (ES2 stepping A0 50655) is Cascade Lake 2nd Gen scalable. supported only with 3.x and up BIOS.

    R640 supports QS, and cascade lake A0 like QQ8Q/QQ8M.

    the MD71-HB0 supports (unofficialy) up to 255W, but i did'nt tested that myself.

    they talk together, "hey how much can you drive ?" "up to 1000Amps, why do you ask ?"

    note the board does NOTHING with a 240W cpu, not just overheating. the VRMs(DrMOS type) are replaced. BIOS remains the same.
