Why won't miner determine what GPU crashes? All it says is:

Also would be nice to have per GPU share(correct\incorrect) counters, not just total. That way you can is if one particular card gets all\most of incorrect shares....

T-rex still continues to run without hashes reflecting in the pool ,even after GPU Lost and miner crashes ,

Please help sort this out in your next update

Have you tried any another pool? seems you can't find any share long time and miner restarts. Also you can increase timeout parameter -T, --timeout - default it's 300 seconds, you can increase to 600 for example.

Pool side seems fine as I'm mining at the same pool using my other systems too .But in this system's case once it loses GPU0 the miner crashes but the monitor keeps sending the same data again and again even if the miner is not hashing , The funny thing is miner doesn't restart instead it keeps showing previous data

Any more info i can provide you ?

How can I fix it? The problem is only with t-rex, with any pool, any bat, other miners work without problems

To make it easier for us to check, please enter a full command line option here.

What is the model of your GPU's?

I believe the solution to your problem is here:

* CUDA 9.1/9.2 versions of the miner will no longer work with RTX (Compute Capability 7.5+) cards
This is done because RTX cards either hash slower or don't work correctly (depending on the algo) on these versions, producing "result for ... does not validate on CPU" errors. Use the version built with CUDA 10.0 instead.

Try it out by adding the --no-watchdog option to your command line.

It may work with watchdog disabled, but this is not the definitive solution.

Hi in the latest version, can you say one algo in particular is the most profitable one, specifically for Nvidias 1080 TI and up ?

Is mining RVN with X16rv2 still the best selection ?..  

Thanks

I would say for the moment Grin-31 is the most profitable one.

Yeah, RVN is at the moment giving negative yields with 1080 TI's, Grin also just barely profitable or break even after 11-2 cents KWH electricity,

dark times for GPU mining...

0.15.3
* Add algorithms: kawpow (upcoming RVN fork), progpow, mtp-tcr
* Add SNI support for SSL
* Improve stat table (now showing percentage of rejected shares)

NOTE (RVN fork): In order for the miner to automatically switch to mining kawpow at the time of RVN fork, please make sure

T-Rex is launched in watchdog mode (--no-watchdog parameter should NOT be set in your bat file)
Your system clock is synchronised with a time server (The miner uses your system clock to check if it's time to switch)
Add "--fork-at kawpow=2020-05-06T18:00:00" parameter to the miner start cmd line. If your pool changes ports for the new algo, make it "--fork-at kawpow:3637=2020-05-06T18:00:00" where 3637 is the new port the miner should switch to (replace it with the actual port number)
