Hi guys, love your miner - question though, I hope your supporting the new Swap (XWP) and get the miner working on it?

Thanks

Hi realbminer,

the ct31 on 8GB cards is buggy and has high share rejection rates up to 30-40% on f2pool

It is a problem pool side on f2pool, I switched to luxor, no rejected shares.

We need to spread the hash anyways, it is impossible that f2pool has that amount of hashrate...

addition: this looks like a memory leak, will you be able to fix this in 15.1?

Hi realbminer,

wonderful that you cuckatoo31 work on 8GB cards. There seem to be some memory allocation issues, I get on several cards the following

*** Error in `./bminer': malloc(): memory corruption (fast): 0x00007f1da06d98c0 ***

I have already tried that, but after 4 instances running, CPU is at 100%. Then i am unable to run remaining two. Performance is degrading even if every card is run on separate miner. For C29 is perfect stable for weeks at 39 G/s.
CPU: G3930
RAM: 4GB
MB: Z170-Gaming K3

Yes i have 1070 gpus restarting sometimes too. and power consumption is unbalanced. İ am using win 7.
What is hashrate of 1070ti? I have 1070tis but in win7 there is memory error

@realbminer
Thanks very much for your support of 8gb c31.

system:
motherboard TB250-BTC BIOSTAR
cpu: g4600
ram: 8 gb ddr4 ram corsair
rigs: 7 cards
gpu: 1070 and 1070 ti gigabyte
psu: corsair 2x1000w gold
OS: linux hiveos
bminer: 15.00
grin: c31

All rigs mistakes:
1070 and 1070 ti gpus miner dies repeatedly and starts again, sometimes 10 minutes sometimes 2 hours. I've tried all overclok settings or even did zero. sometimes the average load is too high
Although the hiveos power is adjusted to 120w, sometimes 200w is happening on the cards. There is imbalance in terms of power.
and 10-20% in pools too rejected.

give me this error:
[FATA] [2019-02-19T18: 53: 57-04: 00] CudaError: Unknown error: C: \ WINDOWS \ SYSTEM32 \ apphelp.dll
Bminer version 15 on rig 3x1070 Win10pro version 1809
version 14.3.1 works perfect

I have the same issues.

FYI, this doesn't solve anything.  Rig keeps freezing whatever the number of bminer processes, even with one per gpu.

You've done all right, but miner didn't support amd cards for cuckaroo29/31 algos.

well i tested new gminer 1.33 build for few hours and bminer 14.0 build still has highest average 24 hour hashrate on f2pool, 31g/sec vs only 28g/sec with gminer latest build, bminer itself reports only 27.2g/sec on my rig (4X1080+1X1080Ti TDP 70% memory +500 + some core oc)  while gminer has 28g/sec and about same hashrate on f2pool, maybe bminer has some extra tweaks that suits better f2pool, rejected shares is 1% for bminer and 0% for gminer, i think it's something to do higher fidelity in longer periods that bminer has, gminer has less fidelity per GPU than bminer for both 1080Ti and 1080 GPU

Getting this problem what is bad with my config file?

Speed is too low on BEAM on AMD cards. Not all pools supported.

Mining C31 with version 15.0.0 for 20 hours on SMOS:
Rig 1= 1080 x2 (0/0/150W) + 1080Ti x2 (0/0/225W) with one crash and average 4.34gps in miner. Pool hashrate 4.1gps.
Rig 2= 2080Ti x1 (0/0/225W) with no crashes and average 1.91gps in miner. Pool hashrate 1.83gps.


Mining C29 with version 14.3.0 for 24+ hours on Windows 10:
One rig a single 2070 (75/750/80%) with no crashes and average 6.17gps in miner. Pool hashrate 5.97gps.

My 2070 would not run C31 on SMOS due to insufficient memory.


Prior to dropping my overclocks, I had stability issues on C31. Also, Bminer can't read the device status for the 2070 on Windows. (SMOS and Gminer on Windows both read it fine, so its not an issue with the card itself).

It does support BEAM on AMD:

https://www.bminer.me/examples/#specifying-devices

Author, remove "AMD" from name of topic. Your miner didn't support AMD cards.

Yes my rig is  crashing too. But in long hours, 9 hours etc.

My memory clock -502 , maybe because of this it is crushing long period. 1080ti hash 1.1 gps

mee too same problem. İs there anyone who can run 1070ti on win7?

make separate bat files for every gpu. Same problem occured for me i solved like this.
