3060 Ti Rig netting more shares than RTX 3080 rig!?!

[TheDude]

Hello Fellow Miners,

Rig 1 has 8x Gigabutt RTX 3080 cards averaging 772 MH/s while netting 6789 shares per 24hr. Rig 2 has 4x 3060Ti and 4x RTX 3080 cards averaging 616 MH/s and while netting 7218 per 24hr. I am shocked that Rig 2 is netting 400 more shares per day using 150 MH/s less than my full 8x RTX 3080 power hog rig. I initially thought my OC settings/timings may have been responsible so I dialed back the OC on the full 3080 rig, without success. Rig 2 is still netting more shares than rig 1. Rig 1 is full of Gigabutt 3080s, which were known to throttle without thermal pads. Makes me wonder if these cards really underperform in comparison to other brands.

I assumed MH/s speed and reduced invalid/stale shares dictated share success. Perhaps that is not entirely the case. I am not sure where to start to troubleshoot the bizarre results. Everything is hardwired to a router. No wifi at all or switch in line. Maybe Hiveon’s worker specs are not precisely reporting values? Maybe Gigabutt’s 3080s are really POS in every way? Any feedback would be appreciated. Full specs below:

I have 2 8x GPU rigs. Both rigs are running HiveOS and mining on the Hive pool. Each rig has a ASRock h110 pro btc+ mobo, I5 7500 3.4ghz CPU, 8gb using 2x 4gb Patriot DDR4 2400 PC4-19200 memory, GPU Risers from GPURisers.com, 2x EVGA 1600w T2 (more than enough to safely power 4x 3080s per PSU, SSD and 7 120mm supply fans.

Rig 1 is populated with 8x Gigabyte Nvidia RTX 3080 OC cards that have thermal pads installed to avert thermal throttling, since Gigabutt did a terrible job using subpar to nonexistent materials for heat dispersion for the DDR6 memory.

Rig 2 has a mix of 4x RTX 3080 cards and 4x 3060Ti cards of varying brands.

Hiveos 5.4.80
Nvidia driver: 455.45.01

Not all shares are created equal. According to @nono he got this explanation from HIVEON:

“With the latest pool update, vardiff was introduced. This means that the earnings are affected not only by the number of correct shares sent, but also by their difficulty. In this regard, the number of shares on the workers may vary.

For example, a worker with 6 cards and 180mh/s and a worker with 12 cards and 360mh/s.
Workers with the biggest hashrate get more difficult shares, and as a result, when compared with a worker with a smaller hashrate, they have a smaller number of shares in general.

That is, in our example: a worker with 12 cards Hello!
With the latest pool update, vardiff was introduced. This means that the earnings are affected not only by the number of correct shares sent, but also by their difficulty. In this regard, the number of shares on the workers may vary."

If I am interpreting this correctly, my rig with a higher hash rate is collecting lower shares, and by proxy, lower revenue. If that is the case, I don’t see a reason to have everything in 1 farm or related in any way shape or form.

[morrisdl]

My interpretation: Hash vs Hash is only valid comparison between rigs.

Shares vs Shares are not comparable between rigs. % valid vs rejected shares can be only used to validate health of a specific mining rigs. Shares can also be used to compare performance of a specific rig over time.

[TheDude]

Still stands that an 8x 3080 rig produces less shares, valid or otherwise, than a 4x 3060ti and 4x 3080 rig. Can’t wrap my head around that ROI.

[morrisdl]

Not all shares are created equal. There is a share difficulty that is not being reported (except on the miner console log after the a few minutes of uptime). It would be nice if revenue was possible to break out by miner. I upgraded a rig from Six 1060s to six 3060ti and the total number of share went DOWN. BUT the revenue went up relative to the increase in hash rate. All good!

[TheDude]

Ya there are certainly things happening that are not transparent. Would certainly be nice to know. Thanks for the info!

I had the same question before and contacted support:

Example to make it easy to understand, numbers fictional:

Low difficulty share = 1$
High difficulty share = 5$

Rig1 100MHs makes 10 low diff shares per hour = 10$
Rig2 500MHs makes 2 high diff share per hour = 10$

Go have a look in the shell/miner. It should show the diff.
Bet that your stronger rig solves higher diff

[TheDude]

Thanks! That is very useful info and great to know.

[morrisdl]

Poor example; both the 100MHs and 500MHs rigs are making same $10 per hour?

I think you mean:

Low difficulty share = 1$
High difficulty share = 5$

Rig1 100MHs makes 10 low diff shares per hour = 10$
Rig2 500MHs makes 10 high diff share per hour = 50$

**5 time more powerful (by MHs) rig will earn 5 times more $, but may only make same or fewer more valuable shares.

[Ericlas]

I guess you are right, but the point came through either way.

It just means just because you get less shares doesn’t mean you get a lower payout, since the lesser shares are valued more.
