Re: T-Rex 0.19.7 NVIDIA GPU miner (Ethash, Octopus, Kawpow, MTP)

T-Rex 0.19.7

* ("ethash", "octopus", "kawpow") Improve stability for 30xx series GPUs
* ("ethash") Verify overclock stability after DAG rebuild ("Instability detected" message is printed in case there are issues)
* Add "--gpu-report-interval-s" parameter to control hashrate summary report frequency based on the number of share submissions
* (API) Add new "pause" command for "control" handler to pause and resume mining
* (Watchdog) Display a list of GPUs caused miner restart with "GPU is idle" error

Bug fixes:
* ("x21s") "incorrect size of extranonce2" error
* (UI) Incorrect GPU index in share submission report when "--pci-indexing" mode is enabled
* (API) Miner fails to switch algorithms on the fly for some ""<algo_from>" -> "<algo_to>"" combinations

Completely unreliable for a 7 card 30series rig with medium memory overclocks 3060Ti +800MHz, 3070 +700MHz and +800MHz, 3090 +350MHz... It cannot create the DAG reliably it will hang and crash miner. However if memory overclocks are reduced by 200MHz on each card it will create DAG why is this? It works perfectly with version 0.19.5 and 0.19.4 (these I have tested with these settings).

This is absolutely not a stable build for me... It just hangs unless used with an extremely low memory overclock.

What power are you using on the 3060Ti? I'm able to run with +1359 MHz on the memory @131W. With +1400 I get 1% incorrect shares

I use 60% power. I do not want to run the memory at such inflated values as it will degrade the memory 700 to 800 I have found to be stable in gaming and normal workloads so I am satisfied with this long term performance. However as stated .19.7 is completely unreliable when creating the DAG.
