Unable to change duplex setting on a IE4010. With a duplex mismatch, is it better to just set both ends to half?

There is no way to set duplex to full on my link it is half duplex. On the other side, it is full duplex(which I can change). If I set both to half, would this be better then having the mismatch?

Will there be any difference in performance? The logs are going crazy.
