But this is with 19 multiplier and 211Mhz BCLK. Only the 20 multiplier doesnīt work

and i donīt think that the CPU need more VCore, PLL & QPI voltage with lower BCLK / Uncore / QPI clock.

for example:

4Ghz: 19x211 / 3.8Ghz QPI (multiplier 18) / 3.16Ghz Uncore (multiplier 15) / 633Mhz Mem (multiplier 3/6) / 1.4125v VCore (Bios) / 1.24v QPI/VTT (Bios) / 1.60v vDimm (Bios) / 1.80v PLL (Bios) <- primestable

4Ghz: 20x200 / 3.6Ghz QPI (multiplier 18) / 3.00Ghz Uncore (multiplier 15) / 600Mhz Mem (multiplier 3/6) / 1.4125v VCore (Bios) / 1.24v QPI/VTT (Bios) / 1.60v vDimm (Bios) / 1.80v PLL (Bios) <- not stable (restart after 15sek)
24/7 stable at 21x191 here (20x191 POST with turbo enabled), you need to raise VQPI, it needs to be kept within .0250~.0375V of VCore depending on VCore gates, try VCore at 1.3975V to start with VQPI at 1.375V, PLL works best on Auto right now on the ASUS board. Also, blck over 200 is a problem in the BIOS you have at 20x multi on POST.
