Polaris Memory Problem Mining

Hello,

I have several RX 570 and 470 and mining ethereum, problem is as file which is loaded into memory of GPU grows gpus seams working much slow, I have read this is because file took 100% of first memory bank (2gb) and go to second memory bank, so access two banks instead of one leads significant performance degradation.

 

My question is is this driver problem or hardware one ?

 

Much older gpus don't have same problem, seams it's only Polaris ones.

 

Thanks
