I have just purchased a cheap 4GB card that later will go into my kid gaming PC. Before he gets to start using the card I thought I try and squeeze out some MH/s from the card.
I have been running the card on Phoenix miner and is getting around 7-8mh/s. And it’s stable. Then I tried to launch lolminer 1.24a and then I start getting “detected a defect share” quite often. If I keep it running I get about 30% defect shares. sometimes I get it after just a few second, and sometimes it takes 5 minutes.
I have played around with the OC settings and have been using the same settings as I used on Phonenix miner but it just won’t work. I have tried turning down the mem speed and clock speed and also run stock settings.
I have also tried removing all 4 8GB ram modules and put in a stick from another system. Tried earlier versions of lolminer etc.
Also, it seems like the errors come after autotuning is completed. just a few lines and bang I get the error.
I am ofcourse running the card in a pcie 16 slot. Have also tried different slots.
Anyone got some input on what can be the issue?
