c 32 on luxor?

Yet, I suppose. Roll Eyes

c29 is currently more profitable than c31. Switched both rigs to c29.

New GMiner (v1.28), has almost reached the speed of bminer v14.1 for NVDIA (applies for 1070-2080, for 2080ti's NBMiner is faster).
Also GMiner is the first miner to support Nicehash. Wink

Yeah, I'm not really baggin on it - just sayin that it seems ironic to justify moving to grimble by saying that grin is no longer profitable...

Exactly. Because currently Grin is profitable.

c29 still gaining ground against c31. Leveling out.
Thinking of switching back to c29, to have actual results.

Yeah I dont know what this guy is getting at.  Even with crazy expensive electric it's still profitable.  All the power to the people who switch off grin mining  Cheesy

nice work here, went to read some of https://github.com/mimblewimble/grin/blob/master/doc/pow/pow.md

guys, you are using cuckoo cycle algo and what is the difference, any source of cuckAroo29??

c29 is implemented for GPU's.
c31 is for ASIC's.
ASIC's are not out yet, so in the mean time you can mine both.
Not sure what 'source' you're asking for. Undecided

continuation of hashrates discussion from Grin Observer thread here:
https://bitcointalk.org/index.php?topic=5102334.msg49585638#msg49585638


ubuntu rig (1080ti) 100% PL (stock)
pool: 5.6 g/s
bminer 7.9  7.1 g/s

If that's average, it's low.

But since we were talking about bench marking and not something general, we could have also had it here:
https://bitcointalk.org/index.php?topic=5104296.0

moving reply to that thread.

which is low? pool or bminer?

ubuntu rig has ubuntu 18.04LTS, nvidia  417.xx driver (i believe will check later), CUDA 10, bminer 14.1, celeron 1840, Z97X mobo, 8gb ram 120 gb ssd. using iGPU for display, the 10880ti is the only videocard. no real cpu load, it runs fpga miner and grin wallet/node code occasionally with no seeming impact on hashrate.

card is gigabyte aorus 1080ti, running stock.
https://www.newegg.com/Product/Product.aspx?Item=N82E16814125954

EDIT: just remembered i have both the iGPU and the 1080ti outputting the desktop in mirrored mode to my KVM, the desktop was messed up with either alone. musta done something stupid to X when i was installing the nvidia driver (i just moved the 1080ti to this rig a couple weeks ago).

Pool.
You get 7.1 G/s on bminer with your 1080ti, which as it's supposed to be ATM.
On the other hand, the pool reports a lower graph rate (5.6 G/s~20% less), which impacts your shares and your profits imo.
For sparkpool is the other way round.
My X4 1080ti's report 28.4 on bminer (same as yours), whereas on the pool side I have an average of ~26 G/s.
Also they fluctuate up to 34 G/s (pool side again). In any case that makes it 6.5 G/s on average instead of your 5.6 G/s.

I cannot post proof of this ATM, cause I had a few power cuts today and it's all messed up. Tomorrow.

checked just now. on grinmint

3 card/win10 rig reports
pool 12.3
bminer 14.3

ubuntu 1080ti
pool 6.7
bminer 7.0

my pool reported average hashrate wanders between 18 and 21 g/s vs the more or less steady 21 g/s reported by the two miner instances.

but ive read bminer reports are a bit optimistic.

ill update in the morning.

Keen on your results after a full day or so.

Almost back where it should be:

4 X 1080ti, Windows, c29, sparkpool, Gminer v1.3.

Looks like c31 is gaining ground today.
Gminer v1.31, now supports c31 with a graph speed improvement (1080ti~0.7G/s).
Added to recommended.

The difference between c29 & c31 has never been more leveled out till today.
Taking into account that it's roughly 10/1 the graph rate factor for c29/c31, we have:



Other calculators also confirm this.
ATM, it makes no difference if you are mining c29 or c31.

New Bminer (v.14.2) also out today, supporting c31 with improved speeds also ~0.90 G/s on 1080ti.
I think I will give it go with this one. Grin

I would like to ask regarding the GPU mining, what type of video card do you use for mining?

The best GPU at the moment for mining is NVDIA 2080ti.
If that's too pricey for you, next in order is 1080ti. Plain 2080 is really not worth it.
The key word is 'ti'. Wink

Is this profitable or just a shitcoin of the future?

I don't know how to help you if it's not your page file dude.
I have seen the error before, related to that in most cases.

I'll have a look around. Wink

Tried. Same low memory issue that I'm seeing on the 1080ti, under Windows at least.

Can't start the solver.
