CCminer(SP-MOD) Modded GPU kernels.

[sp_]

The next release will do around 170 on the gtx 1070. I just need time to complete it.

Any news .

Too busy growing the farm at the moment.
Still working fulltime as a programmer, and my kernel code is done after 8 hours of coding in the 8-4 job.

[giagge]

Ok thanks sp , i hope you release soon , the zcash-spmod1 is very good stable .

very bad this limitation .

Yeah you don't get those speeds on normal cards. People really need to stop quoting their bleeding edge OCs as 'what you get'.

Bensam, you got any performance numbers for that cheap zotac you linked earlier?

Not really... You can OC them as much as other cards, which is around ~1975. TDP is at 112, which limits OCs, memory OCs, and overall speeds depending on the miner. The main limiting factor of Nvidia GPUs are the low TDPs. Pretty much all cards end up around 1975 or 2000. Really depends on the algo you're mining. I don't have memory OC numbers

230 SOL on GTX 1070 .

When work for all pool ? .

in fact I get 240 sols with little trick. Well, 90% tdp of my SJS thow ...

Yup where are the OC numbers? You're using a awful lot more power. 90% TDP with a 8+6 pin card isn't the same as 90% with a 8pin card. They read things differently.

I get 225 sol @ 75% power limit 8pins, memory OC

I get 225 sol @ 75% power limit, memory OC

Anyone tried to set host file to redirect the static adress to another pool? You might need to direct the port as well.
 Then you can use the nicehashminer on any pool.

They mentioned they use a custom protocol, so you can't do that. Someone would need to sniff the protocol and setup a proxy that acts like Nicehash locally.

running my GTX1070 (strix, 2GHz core /+800MHz mem) at 200Sol/s each with the nicehash miner.

Did you try -502 on your memory and check the difference in s/s? I'd like to know plz.   Thx

-500 gives me 170sol, default gives 180, +800 gives 210.

It is a 8 pin card with 170watt tdp bios.
OC is 2135/2375@1.05v
But you won't get 240 only with this ... only 230 ... you need to apply small trick to get some extra and + 6-7% tdp extra power usage with the same clocks

which is strange, must be because of the brand because i can't even dream to reach 2375 with the core and that voltage/tdp

It can do 2400 mem with ETH but only 2375 ZEC. I need do pump memory voltage in palit thundermaster for this memory clocks

same, with samsung and new bios (micron fix) I even get 2500 (stable on same but some rejects on other cards) on ETH but zcash is write heavy and it will cresh so i keep them 2375 too, need to test 24h stability for more

[bensam1231]

Hmmm they don't sell Palit's in the US so I haven't used them. Out of all the cards I have, MSI reds seem to have the best memory OCs. I can get +700 stable while dual mining Eth (which is maximum load situation), +900 for ZEC.

That said I don't go out of my way to min/max all my cards. I usually find a stable clock that works across the board on all the cards and blanket OC them (like 1975 core clock and 600 memory). I don't have enough time to troubleshoot constant reboots on quite a few rigs just for a couple extra cents per day.


Speaking of which. It used to be when a OC failed, say with Maxwell, the cards would fall over into a lower power state and there was no way to actually fix it without a reboot. So when you start a miner back up, the card would sit at 400mhz while all the other cards would be operating normally. Pascal seems to have 'fixed' that, when a OC fails, the driver resets and the card seems like it's working perfectly fine... even though it's unstable. This makes it incredibly hard to find the card which a OC isn't working on without trial and error by declocking a random card you think isn't working properly or blanket declock all the cards on a rig.

Is there anyway to get the old behavior of having a faulty card stay in a low power state after it fails like with Maxwell or figure out which card is failing? I haven't found a meaningful way of doing this yet.

Sp you think this week you have a time to released new zcash_spmod ? .

BTW all the bullshit about 'memory limitations' people were tooting their horns about as far as Equihash goes is just that, bullshit. Someone came up with a random ass extrapolated number and then the tried to justify it using logic. This is also called a confirmation bias.

Claymore is currently pushing past 300sol on 390 and working on another 'good speedup'.

As I've mentioned before, both here and on the Equihash forums. MCU is a pretty good indicator of how 'memory strapped' a algo is. Even at 100%, you can still optimize code so it's more efficient at memory usage. People are fucking dumb and take one thing way too far and believe it's a 'brick wall' without ever spending any time programming or working on a miner themselves, then spread that shit everywhere to get people to believe them.

1070 for instance on Nicehash is doing 65% MCU while operating at 180sol. TDP for cards is also closer to 60% as well (meaning there is another 40% of card thermal headroom mem/gpu). Theoretical increase is another 33%, without optimizing for memory transfers or efficiency, since both are available.

Meaning 240sol is the bare minimum for a 1070, not the maximum and that's just based off of what we can read off the cards while they're operating. And doesn't include power efficiency or memory optimizations.

That isn't to say Equihash doesn't depend on memory, it's just not in the same boat as Ethereum. Stupid eth-babies.

[sp_]

Equihash is different from the other hashing algos. The limit depends on the algorithm. It's a bit like sorting numbers. You have bubble sort, mergesort,quick sort, radix sort etc etc. Each algorithm has it's own limitations. The maximum speed is unknown. There is no known limit.

I merged the changes from the other forks and got a small speedup. Not worth a release
