More info -> CUDA error 'an illegal memory access was encountered' in func 'solve' line 966 about zhasher

[Overdrive5]

Running it for a few minutes now. FYI, adjusting -cb and -ct doesn't seem to make much improvement over just leaving them out of the command line so far. Power draw and Fan speed much lower than (200,9) parameters. Seems like a nice algo for the summer months for sure!

I set debug level to 0 to get more info and this is what I got back:

./zhasher -d 0 -cd 0 -cv 1 -l mine-btcz-na.equipool.1ds.us:49951 -u tmWjhEGegvBSR5c49JNkk4PDyzDFfiNkGBT.RIGNAME

[cryptorex]

are you over-clocking ?

[egyptianbman]

Anytime you see an illegal memory access was encountered while mining, it means your memory overclocks are set too high for the algorithm you're trying to mine.

[Overdrive5]

Yes I am. I'll check it with stock clocks. Thanks for the help! I will reply back with the results.

[Overdrive5]

Yep, That fixed it!

So it is using 2.683 GB.
Sol Rate is under 3.5 Sol/s for 1070 ti ? Is that normal for the new algo?

[cryptorex]

@Overdrive5 yes - the hash rate will be much lower with this algo - everything (difficulty, network hash) ends up being adjusted down. Everything will be relative, in other words.
