T-Rex 0.26.8 ETHW, ETC (+dual mining) GPU miner

[Kodaman]

Will there be an improvement on the X25X algo?

I am having problem with one of miners. It is W10 1903, 2x1070 Nvidia with latest drivers. Cpu usage is locked on 100% on miner I downloaded today latest miner for rvn fork ..

If you also have updated your drivers, go back to an older version (430.x or 431.x). Its a bug in the newest driver, which will result in most systems in a 100% CPU usage.

Thank you, bingo. Reverted to 419.23 and then to 431 and working ok (both).

Has anyone else had an issue with version 0.11.1 and above having the miner shutdown after around 3 minutes with the error "T-Rex instance wasn't validated", "Messy shutdown"?

I'm mining MTP and have 2 RTX 2080's running in Windows 7 on the latest 430.86 nvidia drivers.

If I revert back to 0.11.0 I don't have any issues.

I'm having the same issue;
TREX: T-Rex instance wasn't validated

trying to upgrade to support the RVN hard fork but the new version keeps shutting down, on Linux. v11. use to work flawlessly
Driver Version: 430.50       CUDA Version: 10.1

I don't have any firewalls that should be blocking this machine, on spectrum internet.

Checking if my rig can get to the dev fees and i get this:

Is this part of the issue?

can you talk a bit more about your mining projections after the RVN hard fork, will it resume its spot among the top contenders as the most

profitable coin to mine with GPU's, or would you decisively recommend to mine something else particularly for 1080 TI's at the moment ?..

unfortunately, due the situation on the global cryptomarket, low profits on 1080ti we have now not depend on the miner
of course it is good to squish extra 2-5 precents of margin because of miner's optimizations, but due to the fact, that new, optimized version of the miner will spread over miners and global hashrate would grow and profit will be same as before miner's updates .

[hustleman]

With the new algo for Raven... whats the best intensity for 1070s, 20 or 21?

[jebidia]

Does the updated miner work better with 2080 cards?  My 1080 ti machines are fine but I crash with the previous version.

For comparison of cpu usage, Driver 436.02 vs Driver 430.64 took a few days to identify that new drivers were overloading cpu.

Driver 436.02


Driver 430.64

[Vispilio]

so looks like profitability is back for RVN after the fork, just to confirm does the new algo on 0.14.4 work as smoothly as before,

what are your newest results if anyone can make a comparison with the past versions pre fork ?..

this is really strange, but on my pc there is no difference in cpu load for both versions. no idea why it is so? might be the reason I'm using 1080ti not the new version of nvidia cards with this modern tensor cores?
also I have to mention that performance change is very low, so basically no need to upgrade imo, better save time and stay with current version.

[nambu]

Any benchmark on 1660ti ?

I updated the driver after the security alert made by nvidia ... In my case it affected the cpu overload, maybe for other gpus models this doesn't really happen.

does anyone here know why nvidia 436.xx driver versions are eating up cpu resources while using trex miner?  431.xx versions and below doesnt have such issues.   anyone encounter the same problem or is there a workaround solution to not use my cpu resources while mining.

This not only affects T-rex ... but all mining software, the solution is to keep using the old drivers ... I like the 430.xx

im mining with my PC, i have an older GPU thats not compatible with t-rex miner and i have a 1060 that i want to mine with, how do i select theGTX1060 card in trex as its throwing errors with all writing in red.
t-rex -a x16rv2 -o -d 0 stratum+tcp

the following works with
t-rex -a x16rv2 -o stratum+tcp

but i get this error
