hello.is there a possibility to overclock the device?...for example to reach 4.5T?

Given the problems some folks have had running it on High, not a good idea.

For 1 your would need to improve the airflow through it.

More in line with reported problems there is then the point of how much power the USB-C PD circuit in it can handle. In most cases the power flows from connector directly into and through the PD negotiation chip reported as chip-5. If the PSU says it can provide it, that can be up to either 28V for the nano or 42VDC for other devices @either 3.5 or 5A for either voltage. Some folks have reported that the chip can get too warm and develop bad solder connections so I would not recommend pushing it.

I've been using them for 1 month on HIGH and I have no problems. both covers are down and I have temps between 32 and 50 degrees. i also have a BITAXE where you can play around with the voltages and frequency...so if the chip has a bit to spare...

I can't explain it.
For some people the device works without problems, for others it doesn't.
What could be the reason for this? Has the design of some devices been changed, different chips used or something similar?

Agreed. I've posted here before, and wonder a lot about why it be so very different from user to user?
(For instance what is the point of having a high setting when it only works on, let' say... 1-5% of all devices? What is the reason for it NOT working on high for the rest of us?)

because the design depends a quality usb-c cables with a proper chip inside them.

Also constant 24/7/365 power draw keeps a lot of heat on the chip in the unit and the usb-c cable's chip.


This gear will not last at high without an effort to cool the 2 chips.

Stupid design flaw.

best way to understand this is to put an infra-red temp and check the heat where the 2 chips meet.

shame as I do like it. I suspect this will break on me this winter as I have run them near an ac/heat vent once the heat comes up in the winter I think these will break.

Would love to see them keep track of the best share in the GUI / Pool stats that the miner has submitted since running as well as best per session.

You do get a glimpse of the best share per session in the logs but unfortunately those get wiped out after every reboot.

Point it at kano.is if you want permanent stats. It shows the best so far for my Nano is 3.9127G on 9/14 @ 2.21p EST.
