p106-100 vs p106-090 mining ETC/ETH

[ronnieb]

I acquired some second hand cards to see if it would be worth building another rig in the garage. I have a p106-100 6gb that i am very pleased with that can output 27mhs after some OC settings.  Another card I have is a p106-090 6gb version that has lower cuda cores but retains 6gb of memory.

for some reason the p106-090 can only hash to 13mhs on etc or eth but has no issues with hashing at around 22mhs on other ethash coins with lower DAG. Not sure how this is possible since gpu-z states that this card is a 6gb card. perhaps the lower cuda core count has something to do with it but im not sure.
