wow, u have B2 stepping. How strong is it in allcore load? IMC is laso very good :)

All core can run 4850mhz CCX1/2 @ 1.42v.. single core boosts fine to +5.1ghz on each core so far. This is 1 of 11 CPU.. all are B2 and within ~150mhz clocks on AIO. IMC went to mobo limit @ ~4400mhz C15

After some more work.. 4666mhz C16 was possible with same CPU/mobo/RAM combo. Oddly enough, new bios ver now allows clocking fclk to +1900 without WHEA errors present.. though something is still not happy completely as times get abysmally slow

1900/ 1:1 1b y-cruncher = ~21.9s

1933/ 1:1 1b y-cruncher = ~40s


 So..3800 tight for Pi is still my limit it seems. Either way.. B2 stepping look good but still suffer from ~1900fclk cap

Efficiency looks very good, have you tested BenchMate 10.5 vs 10.11 and newer?

No, I didn`t expect good result. My C8I died and this was cheapest temporary replacement for 24/7 use. Know I sold both CPU/MoBo.
