Gincoin profitability much lower than expected

[bgnacx]

My hashrate is about 40 Mh/s. Based on a few Gincoin profit calculators my income should be way more than what it is. For example I have mined Gincoin for about a month an I could mine about 24 coins. Calculators say that this number should be about 72 coins!
I have tried bsod and angrypool.

Miner: tdxminer
OS: Ubuntu 16.04 LTS
GPU: 6 x Vega 64 liquid cooled
Hashrate: 40-42 Mh/s

Any idea why I can't get what the calculators predict?

I appreciate if miners with lyra2z experience provide some feedback.

[gameboy366]

This is normal with lyra2z miner tdxminer. You will get less then what the calculator says.

But this should not be related to the miner because the pool confirms that my hashrate is around 40 Mh/s, but earnings are much lower.

the same situation. I have 25 Mh on Nvidia. Gained 2 times less GIN. I tried to Bsod and Angry. Sorry for Google translate.

similar situation. on first test with one rig i got 2x less than expected. I have setup another rig with much safer settings like more voltage for core, less mhz on core, less mhz on ram. maybe mainer is generating a lot of errors on tight settings that seems to be ok?

It seems that the miner does not report the rejected shares stats but eyeballing the logs suggests that shares are being accepted by the pool. The cards are stable at ~50 C.

hiveos setup with tdx was easy, hardest part was toi understand that there is already wallet ready to use - just switch wallet addres and it works like a charm. seting core/voltage was a little strugle, but somehow i am getting 2x less coins than expected. I am doing right now test on one rig
8x sapphire rx 570
core 1275
voltage 1000 1025 975 1000 975 1000 975 1000
total usage from wall 1150w
~3.1mhs per card, ~25mhs total
accepted shares from miner  99.67%
pool shows no rejected shares

0.3gin in 12h
calculators show like 0.7gin in 12h

I have a feeling that boosting voltage a little or lovering core could help.
it seems that ram does not affect mining hashrate. i have setup ram on 2000mhz

So i am testing another rig where cores have more power and less core speed so should be more stable. If miner does not report dead shares, then i should see difference in 2 rigs on pool - I hope.
As I understand also nvidia miners have same struggle. So tdx miner hire is not to be blamed. Maybe pools are? Or calculators?

[peteris-apse]

my tests seem te fail... still 3x less income than expected. trying different pool.

are all of you testing tdx on hiveos?

[peteris-apse]

i did not found the reason why i am having 3x less coins than calculators show so i will not try to mine gin coin anymore
