I have a wide range of hardware error rates.. I am wondering if they are related to cooling, luck or random chance... So before I go tearing down my cards and reseating them how do these numbers sound?
1 card at 3.5% error rate, 7 cards around 8% error rate 2 cards at 10% (and change).
So should I be worried with 10% error rates or is this one of those random chance things?
Thanks in advance.
It is definitely a factor of chip cooling and airflow over the mosfets.
I started with an Accelero II mounted in line like you would on a GPU and the heatsink fins were over the mosfets... I averaged about 8% errors.
I rotated it 90 degrees and an 80mm fan right on top of the mosfets and gained a couple GH/s and down to 5% errors.
I have now moved on to an H60 Corsair water cooler and the 80mm on the mosfets but am now back at 8% errors (i believe due to the fail hardware included in the refurb box that wouldn't mount properly...) I am getting some long bolts and nuts to use a much better backplate tomorrow and expect the change to fix my issue and increase hashes.
UPDATE: Bolts, washers and nuts used to reseat and mount the water block... 33 GH/s and 4.4% HW errors.
