Hashfast per die clock rate setting:

I have noticed that in driver-hashfast.c, there seems to be adaptive clock rate setting per die:

Code:

applog(LOG_INFO, "%s %d: Die temp below range %.1f, increasing die %d clock to %d",
hashfast->drv->name, hashfast->device_id, info->die_data[die].temp, die, hdd->hash_clock);
hfa_send_frame(hashfast, HF_USB_CMD(OP_WORK_RESTART), hdata, (uint8_t *)&diebit, 4);

Is there a way to set per die clock from command line or conf file? Reason I'm asking is one of my dies seems to work fine up to 150MHz then it completely stops working and I would like to clock dies 0-2 with normal clock and underclock die 3.

Edit: By the looks of your comments and the code it seems that per die clock setting will be possible for FW 0.5 and up. Do you already got FW 0.5 from hashfast by any chance?

Older firmware 0.3+ can do per die clockspeeds as well but when there is a large difference in the clocks it causes huge dips and peaks in the metering out of work which can present temperature and other issues. It is not possible to set clock speed per die on the command line yet but it is possible to add that feature.
