CCminer(SP-MOD) Modded GPU kernels.

[shubaduba]

@shubaduba thank you, restarting the miner shows new blocks being found on the network (not by me).

Wait, so the hash rate being shown is not actual what is being sent?  We need an 8+ core CPU to mine with 8 GPUs?  Man, I had no idea.. I wish he would have said something about this before.  Is there no way to check the actual hashrate that is valid?

Wonder if it would be worth it to upgrade from an i3 cpu to an i7 to mine nexus?..  for now I guess I have to abandon it and consider the time I spent and the .05 btc a lost cause

Glad that is worked for you.
I'm not sure it worths to upgrade CPU only to mine Nexus.
First, there is a possibility than some serious rework will be done to miner and that CPU issue will be fixed.
Second, Nexus can drop in value.

But in general, upgrading to i7 or to Rizen CPU could be good investment in future, when new algos or miners will be better optimized for top GPUs like 1080ti and CPU usage can rise significally.

I've mined 50 Nexus blocks in the last couple of days and never once had a single orphan. But I see a lot of people having them. I also never had the miner crash on any of the rigs.

Not a massive sample size, but from my experience both majoh's and sp_'s miner only finds about 1/4 - 1/5 of what the diffculty and miner's hashrate would dictate. That could be an issue with the wallet, I'm not sure but the fudge factor is huge with this one.

As I've said before. Nexus has POS blocks, prime blocks and SK1024 blocks. My mod can only mine the SK1024 blocks. The weight of the SK1024 blocks is not 1/3rd of the found blocks, it's less.

SK1024 is only 1/7 of the found blocks. (There are 1 CPU block, 1 GPU (SK1024) and 5 PoS blocks)
As I understand, we should multiply current difficulty by 7 for profit calculations.

Then you leave the difficulty as it is and divide by the profit calculator result by 7.

I have 40 GB virtual memory. It crashes with both included test bats, maximum time I got it working with 6 cards was 10 minutes. I tried intensity 30 but it doesn't help, just lowers hashrate. Also tried the #6 version you sent (it was faster at 900 total)

I sendt #5. Can you  try it please.

the only way to mine nexus is with the skminer. All other public miners have the same "bug". I am working on a bether fix in #7.

How big is your psu, and wich tdp settings are you running at with 6 cards?

Doesn't work, crashes too after a while. I'm using G2 1300 or double G2 750 with powered USB risers. The TDP I set depends on the algo but for this miner I tried everything on stock to try and get it working. I tried the "official" mumus-mod3 miner and it works without crashing but only at 500 Mh (still uses 100 % CPU though).

And yeah, you could of mentioned that this miner actually doesn't even work correctly without enough cores for all the GPUs if that's true.

50 blocks is around $640 in two days. Nice.

What cpu do you have in your rigs. Os / memory ? And cards?

Yes but the difficulty is what causing the difference.

Unless that's not the real SK1024 difficulty (seems to be real because the miner also uses this), that number is all that matters regarding how long it takes to find blocks with a given hashrate. It's just simple math.

Win7 x64, Pentium G3420, 8-16GB RAM (8GB pagefile) 4x AORUS 1080 Ti per rig.

In 67.1 hours I mined 54 blocks. Taking the average difficulty, I mined exactly 25% of what I should have based on the difficulty. Same difficulty calculations that work accurately for every other coin, including multi-algo coins.

how many rigs mate? ...

ie - how many gigabyte aorus 1080ti ( or Xtreme ) do you have to get these figures? ...

[Dr_Victor]

The same question here. Your cpu is not so fast with 2 cores, can you tell us the load?

[sp_]

Spreadminer #11 is complete and in testing.

- Fixed exit up on crash. (No more craszy hashrates)
- Faster default launch configs with a nice boost on gtx 750, 950, gtx 980ti, gtx 1080ti, gtx titanx
- Improved OC capability (seems to like -500 on the memory and boosted core clock)
- optimized at least +2% on all cards.

Only 6 rigs so 24 x 1080 Ti (half of them Xtreme) running at 150 watts each as I'm heavily power starved for now. 4080 Mh/s total. Do note that even without a power limit this algo doesn't use more than 190 watts on these cards.

100% CPU usage.


Adding some explanation to difficulty and how it works, let's say the difficulty is 1000. Then it means 2^32 x 1000 or 4294967296000 hashes are required to find a block on average.

So if someone's doing 1000 Mh/s, that's 1000x1000x1000 hashes per seconds.

4294967296000 hashes divided by 1000000000 hashes/s equals 4294 seconds.

So with 1000 Mh/s and 1000 difficulty a miner should find a block every 4294 seconds, or 71.5 minutes on average.

But for this coin with skminer this isn't accurate. Maybe because of the CPU usage, maybe because of something else in skminer, maybe because of the wallet, I don't know.

Variance (or luck) of course can heavily skew the results. But I do get 75% fewer blocks consistently.

Yes. I have sendt the file now. Please report in my thread what results you are getting. I have only tested on gtx 1060, gtx 970 and gtx 1070. Also check in your spam folder of the email provider. Sometimes the file is located there.

It seems much more faster than 2% but I'm not sure because the 2nd and 3rd times I started it my rig hard froze both times because you reintroduced the hardcoded realtime priority.

People can use
START /high ccminer.exe ...
or even /realtime to start anything with a given priority, there's no need to hardcode it as hardcoded realtime priority freezes my and some other people's rigs. And the start command's priority switch doesn't work if the priority is hardcoded.

I sendt spreadminer 11 fix 1 out. Check your spam inboxes.

[sp_]

Yes. Nice speedup on many of the cards, but it is using more power, so run with -500 on the memclock to save some power and boost the hashrate.

Guys what are you getting on the gtx 1050, 1050ti, 980ti,1080ti,titanx?

[trobnor]

Getting 15.9 to 14.9 on my 1080ti with -502 +150 and x 28
the 14.9 is just on a card that lost the lotto
5x asus 1080ti turbo

* so that would be a 0.5 increase on all cards form the last one
btw is there a way to level out the power draw it is spiking alot
