I also seem to have degraded my best chip - did 5589 at its best times but now it can hardly run 5.5 on air anymore (which was easy at the beginning). sended it to a friend for a session and he managed 5.55 under ln2 but didn't came close to 5580. when he first tried water 5.4 was all he got
looks like past 1.62-1.64V the degrading issues start.
Been benching my 2nd best chip a longer term under air just around 1.55-1.57 and he seems to be fine with it even at high temps (60+ but sub 70).
no I only edit the records.dat for having nice times in the overview when starting pi
