Hi Guys, I'm facing some hashrate dropping problems which need you to help on.



I have some rigs with 1070/1070Ti 8GB cards which already mined for 3 years.



But after I switched from Claymore(It's such a pitty Mr.Claymore stops updating, wish him all the best) to new miners like PhoenixMiner, T-Rex, GMiner...etc. I found out that all my rigs hashrate drop.



When Claymore miner is still working, my rigs with 8 cards of 1070Ti can run at 274 Mh/s with 34.6 Mh/s each card. But now with new miners, it only gets 252 Mh/s with about 32.5 Mh/s each card.



When Claymore miner is still working, my rigs with 8 cards of 1070 can run at 245 Mh/s with 30.5 Mh/s each card. But now with new miners, it only gets 205 Mh/s with about 25.5 Mh/s each card.



I'm wondering if this is affected by different miners or bigger DAG File size or just GPUs get aged?



I'm grateful for all your suggestions and opinion sharing.



Thank you for the help guys : )



PS. I'm mining with Windows 10 64-bit
