hello i got this error when t-rex restarted

can anyone help me pls

[angelbbs]

Actual h\r on pool side is indeed 50% of reported.

It's a known problem that only occurs when mining on nanopool, we're looking into it. Mining on other pools is unaffected.

as follows, up to 50% of the rejects on nicehash

Which version? If 0.21.2, could you upload the log file?

Just updated to 0.21.2 and now displayed memory junction temp is very high and does not correspond to any of my sensors. Any idea?

Also, Windows Defender is now reporting T-Rex as a PUP. Just thought you'd want to know.

Just updated to 0.21.2 and now displayed memory junction temp is very high and does not correspond to any of my sensors. Any idea?

even if the sensor is lying, your video card is not energy efficient
usual parameters in the batch file , example --lock-cclock 1140 --mclock 1000

We're revamping the webUI at the moment, so should be able to fix it then. For now, you'd need to either disable share validation (to get rid of "I" metric), or widen your browser window to avoid wrapping.

(autolykos2) Minor performance improvements (mainly Pascal GPUs)

I got like 0.1% h\r increasement on 1080ti)))

It varies for different models. Should be ~2-3% for 1060.

Hi guys,

Hope you are fine.

Sorry if it has already been asked, but i'm looking for a free tool to monitor computers on same lan mining with t-rex on windows.
i can access api via http and can NAT it to access it remotly but cannot regroup all my rig in one place.
I have a lot of computer and would like to regroup in one UI (for instance zabbix, grafana or others) to be able to see if one of them has a trouble.
I'm multi mining on those computers (chia farming, xmr, and eth).
I've found https://github.com/lennykean/MiningMonitor but doesn't seem to work or i don't know how to do it.

Sorry for my english i'm frenchy.

Thank you for your help

Regards
Tim

Please fix --tfan behavior when t° is too low it would spin to 100%

[trexminer]

Please fix --tfan behavior when t° is too low it would spin to 100%

If keeping the fan at 100% is not enough to bring the temperature down to t°, then spinning them at 100% is the expected behaviour. Or have I misunderstood your request?

[Divinity666]

Please fix --tfan behavior when t° is too low it would spin to 100%

It happens when actual t° is lower than --tfan by 10C° or so.

[trexminer]

Please fix --tfan behavior when t° is too low it would spin to 100%

It happens when actual t° is lower than --tfan by 10C° or so.

I see. It could be a bug or a conflict with some other software capable of controlling the fan. Would you mind running the miner with "-P -l trex.log" and upload the full log file when it happens again? Thanks.

Lol alright I was chill when it said you were a low-risk PUP but now you're scanning as a known trojan? What's going on here bud?

Is it safe to underclock memory more than -502?

MSi AFter burner has a -502 limit, using --mclock i can underclock even more...

Worst that can happen is card hangs and system requires a reboot to unhang it (and of course remove the oc/uv that caused the card to hang).

Please add the option of power limit --pl in Linux as when I try to start the miner with this option it gives the error GPU Power Limit not supported in Linux.I did manage to power down the cards with nvidia-smi command but it would be much better if this option is implemented in the near future.
