hsrminer - Nvidia mining software for various algos by palgin&alexkap

Palit gamerock 1080 - they are all micron GDDR5x
real GPU clock 1960Mhz (power limit 90%) manual clock

memory real 5022, +504 in MSI afterburner

1070 in same PC with less clock ~1850Mhz is faster by 10% and does not ask for memory OC

Also 4x 1080Ti now works on one instance but hash rate drop 6-7% per GPU
4x instances is faster, same settings, -i 17.5
maybe you need to tie each GPU to different CPU core in one instance?

Strange, I'll need to collect more feedback before any explanation to this behaviour, will add your config to my list.

Thank you for participation!

Try tweaking intensity higher,  17.5 allocates little more than half of 1080Ti memory. Try 18 if you can.
Think I'll add some kind of scheduler in next release to tweak work distribution manually.

Will test later

OK, thank you for tests. 18.5 and 19 is way too high, no such memory amount on consumer-grade GPUs nowadays

I updated thread 17.8 is 7870MB use like it can not pass 8GB and card is defo 11GB  

-i 17.9 well its 8296Mb still works
-18 alocate for a sec 8720mb and exit with error Cuda error in func 'neoscrypt_cpu_hash_1080' at line 1447 : an illegal memory access was encountered

klaus ccminer -21 works but use low memory, i23 try just ~3600MB and does not start too

UPDATE:
5x 1070 on dual core
one instance does not slow down compared with 5x, but I need to drop intensity from 17 to 16.x but its looks like system is limted by just 8GB of ram and 16GB swap

so only 1080Ti have problems with multy GPU with hash drop on ine instance all GPU

Seems this time has come when I should buy myself 1080Ti for developement

P.S.: preparing little tweak for 1080 kernel, will update binary after tests.

don`t be like sp_ he earned 100+ BTC for other ppl work and he still don`t have 1080ti nor 1080 I think!

It's not the money question, when I was building my farms I choosed 1060 3G setups, just before this spring havoc around GPU shortage I've bought some 1070's and 1080's , after market disaster I didn't even look at hardware anymore

Test on my personal heavy undervolted settings with fixed voltage(800mv) and strap. 1695 core, 4000 (8000) mem with p2 off so no drop on mhz when mining.

1070:
Klaust: 1070 kh/s
Palgin: 1150 kh/s (+7.5%)

1070ti:
Klaust: 1240 kh/s
Palgin: 1367 kh/s (+10.2%)

But couldnt start it with all 6 cards, with 1 is ok, with 6 mem error, havnt tested on how many the problem occurs.
Dont have cards with gddr5x because the suck on ether, neoscrypt and monero.

Please add working api, so Nokia555 can add it to Ethmonitoring.com

Thank you for feedback, according to developement plan at first I'll make algo coverage, then features will be added. Neoscrypt was quite a heavy job for me, so I got stuck for about 2 weeks, but I think I'll switch to lyra2v2 or nist5 now and return to Neoscrypt later.

UPDATE: re-uploaded Neoscrypt binary with small 1080 kernel tweak, can boost 20-30 kh

[reb0rn21]

For neoscrypt when you have a time best would be if power use can be optimized, all my cards are hitting power limit this heavy limited 1070 to ~120w have low speed gain 1-2%
the algo is so heavy on power

[cryptominer420]

Was going to update previous post but there were more replies to the thread than I expected.

Environment is inside closed cases ambient temps are 72F

Neoscrypt hashrates using Klaust
Getting 1434KH/s Temp 70c on stock clocks 1080TI FE
Getting 1186KH/s Temp 78c using stock clocks on my Zotac Mini 1080

HSRminer hashrates:
1080TI FE
No adjustments 26.9% increase miner side
speed is 1933.92kH/s, Temp 69c, zPool.ca 45 Min average shows 2133KH/s

Zotac Mini 1080
No adjustments 8.86% loss miner side
speed is  1016.32kH/s, Temp 80c, zpool.ca 45 Min average shows 1216Kh/s

guessing miner hash is calculating after devfee adjustment.

Now I just need to be able to fetch ccminer style stats and I'm using it for my 1080TI

[reb0rn21]

I would drop power limit on 1080Ti it can draw over 300W and your is on limit

mine at 80% is using ~200w I don`t like to push it more, clock is ~1400-1550mhz for GPU

My 1080TI if I am mathing right should be pulling only 230-235W miner was only showing 220W. It is all just setup using stock settings on driver version 388.31

My 1080 runs very hot because it is in a airflow limited case.

I need to clarify about devfee, there are two techniques implemented in miner, which one to choose miner decides itself during start:

1)2 stratum threads with 1% of CUDA threads running on dev
2)1 stratum thread running in cycle User-Dev-User (proportionally 99/1)

In Neoscrypt case only second variant avaliable regarding to kernel specification and during pool switches there are delays (sometimes 5-10 sec, depends on Dev pool and User pool load and connection stability). As average hashrate calculation is based not only on number of hashes, but also on the timeline (including connection delays), so after each cycle User-Dev-User switch average hashrate will be shown less than it actually is.

To sum up: check speed on pool or after 10-15 min from launch on miner side.

UPDATE: for 1060 3Gb and 6Gb users specifically, please, re-download binary from GitHub, fix for 6Gb version 1060's implemented.

Until any critical bug will be found or until I'll buy 1080Ti, Neoscrypt developement will be frozen from now, I'm switching to other algos.

Hey,

Tried to use your miner, but it seems it require a certain version of nvidia drivers (is it cuda9.1 so needing the latest) ? im using 385.28 and 1070's, can you tell me the required lowest version ? Also any chance to get a working API ? it's really crucial to use  your miner in a production environment. Keep up the good work  

Cheers.

[shubaduba]

1070: same speed as Klaust 8.17 (-i 17.5)
1070ti: 4% faster  (-i 17.5 both)
1080ti: 20% faster (-i 17.9 max, 1830 kH/s with +80 core + 200 mem @250W vs 1650 kH/s at Klaust 8.17)

This is awesome!

The only problem is API. I miss Awesome miner monitoring with lack of API.

Hi, yes, it's CUDA 9.1 (just to keep actual CUDA version), so the lowest driver I think is 388.3x .

I've got dozen requests for ccminer-style API, it'll be added, can't say exact time bounds, but I'll work this way.
