I'm having trouble getting 5.1c to work with rx5600xt mixed with polaris 4xx-5xx is there something I'm doing won't says can't create buffer for the navi card makes no sense to me I know Phoenix miner says it works with 5700 cards but does it not work with 5600xt or is it because my rig is a mix of polaris and Navi?
mixed GPUs is not the issue. make sure you have malloc variables set and configured the cards properly. overdriventool is recommended
