I've got an 8 gpu rig with 4 Zotac GTX 1070 Mini and 4 MSI GTX 1070 Aero ITX, all 8 GB. The result for 1070 is an average for them.

Unfortunately I don't have any 1080TIs. If you do, it would be really great if you could try it and post the results. Thanks!

1060/3@75W: 12.8MH/s
1060/6@75W: 14MH/s

Thank you, around 5% hashrate improvement over Enemy and anxmod. Hope it is the same on poolside.

Not yet, but it's certainly on my to-do list.

Getting this error on a couple machines one Ubuntu 16.04 the other 18.04

./t-rex: /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by ./t-rex)

I'm guessing libcurl3 package isn't up to date, at least on 16.04. Could you contact me via direct messages please? We'll try to investigate this issue. I can't send you a direct message because of the default bitcointalk policy not to accept them from newbies.

In fact, I just found a person who faced exactly the same issue and the solution was "sudo apt install libcurl3" (Ubuntu 16.04)

Lux should be changing algo soon, is this miner compatible with the new algo?

LUX is going to switch to phi2 algo which uses different crypto functions under the hood. I'm planning on adding phi2 support but not until I make it fast enough, otherwise there's no point.

Here you go, cuda 9.2 version - https://mega.nz/#!qJsQlAKB!rOpHtsqWjwvKzIljvL1uXO4bv3G-ZeWEB1XAMLWvpgk
I haven't tested it properly though, may not be stable or as fast as 9.1. Let me know how it goes.

3750MH/s on 1080Ti
1200MH/s on 1060/3

Hive doesn't have the libcudart.so.9.1, so perhaps you should include the library in the binary.

The miner crashes on the default intensity of 17 with this error:

Lowering it down to intensity 16 seems to have solved it.
Can you enable the default API?

We estimate a windows version to be available in a couple of weeks. There's two of us working on this miner, and windows version + API are being developed in parallel to adding new algos.

Many thanks for reporting this. Unfortunately I couldn't replicate the crash you've experienced, tried it on 1050, 1070 and 1070ti and it all worked fine with -i 17. Was it 1060 or 1080ti that crashed?
The API, along with the windows version, should be available in a couple of weeks.
Also, I was wondering if you could benchmark phi1612 on your 1080ti for our stats?
