Ive got decent stability around 0.75-0.77V / 200-206MHz / TO=55 works and 90-100% of chips run well to produce 95-105GH/S1

going any lower to 0.7-0.74V / 193-200MHz / TO=50-60    seems to produce mixed results, usually 50-80%  of the chips function and I have around 50-75GH/S1

going any higher to 0.78-0.82V / 200-215MHz / TO=50-60    seems to produce decent results, generally 70-90% of the chips function and I have around 95-115GH/S1


i think these dont necessarily run well at the same settings as the S2 for whatever reason. running around 0.75-0.78V and 200MHz is probably the sweet spot
