hash sequence A returning no shares #25

Closed hillbilly00 closed 6 years ago

hillbilly00 commented 6 years ago

When hash starting with A are encounter, miner returns no shares. The hash rate will drop all the way to zero until a new sequence not starting with A is encounter.

Example: A26CD0943B1578EF A4097E3F61258BCD

System Notes: Ubuntu 14.04 LTS Nvidia Driver 390.48 gcc-5

Has been compiled with toolkit cuda-8 and cuda 9.1.85. Did not use cuda 6.5 due to error no support for Arch 61

Hardware notes: intel i7-7700 1080 ti 16 gigs of ram no overclock

Special Note: Paired with 2 cards or 3 cards made no difference. ccminer 2.2.5 running along with nevermore 0.2.2, ccminer had no problem with hash sequence starting with A.

Tried -i setting [17…19] made no difference.

The miner works great, except for hash drop on A.

I really want to use this miner, please advise on solution.

Many thanks for your hard work.

Update 7/25/2018

Consider the issue closed.

Solution use Nevermore V0.2.3. It will compile with Ubuntu 14.04 LTS, Nvidia Driver 390.4, gcc-5 Been using it for over 30 days 247 and no issues.

Tip for Nvidia 1080 ti users, keep the i <= 18 for long term stability.

Thanks for all your hard work.
