hi, after used your free polaris 1 click my 570 8gb only from 24.5mh increase to 25.5mh without OC, both of the card are same Samsung chip and Biostar brand. so is that gpu problem? so the new version of polaris problem? Im using window os phoenix miner 5.4c. Using AMD Radeon Adrenalin Edition 18.6.1, not going to use the newest driver because it will pop out wattman settings have been restored bla bla bla.

btw i am using biostar brand, if i want to buy 570 8gb Performance timings from your shop, which should i go for?

Have you switched to compute workload?

For better performance you need to OC the memory, if it's like 1750 MHz, you have to push it to 2000 MHz or even better higher than that. Check for memory errors in HWinfo.

yes for the 2 card im already set to compute mode it only get around 25-25.5mh without oc, cant use msi afterburn for it becausae when i set any number of memory core, when apply cpuz will show it is 2300MHz. After that i use amd wattman from amd software oc memory core to 1900MHz it will be around 27mh but with around 50% reject. When step in 1925MHz my computer will restart and the card will go back to default setting 1750MHz, is that means i just bought a shxt card?
