CCminer(SP-MOD) Modded GPU kernels.

[sp_]

I am working on a version #7. Free update

[sp_]

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.

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

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

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.

Yes but the difficulty is what causing the difference.


getmininginfo
{
"blocks" : 1448587,
"timestamp" : 1499615526,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"primeDifficulty" : 7.73370440,
"hashDifficulty" : 1071.74271598,
"primeReserve" : 196.88385500,

"primeValue" : 13.67753400,
"hashValue" : 13.67752100,
"pooledtx" : 0
}

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? ...

tanx ...

[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.

Does it mean we will receive it (who bought)?

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.

Ok. I will fix it. and send out another version.

[sp_]

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

Version 11 support -x 56 and -x 84 (I think) but use more power and memory (gtx 1080ti).  
I also tuned it for the titanx.

Not sure if it improves the hashrate, but worth a try.

56 performance loss 84 wont start
running 4 cards of a 1300w and 1 of a 1000w not sure if i am hitting the limit on the 1300w one

tested cryptonite mod3 for 1070, memory 4500, gpu 1900 :
cards with samsung memory - up to 19 mh/s
with micron - up to 18 mh/s

This SP-mod 11 looks great for having 4x 1080 Ti.

[bathrobehero]

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 ?

V10 fix3 @ 192W PL, +80/-502 - 14.3 Mh/s
V11 fix1 @ 192W PL, +80/-502 - 14.7 Mh/s
V11 fix1 @ 275W PL, +80/-502 - 16.0 Mh/s

So that's 3% BUT I'm heavily power starving my cards (192 watts for the test) as I have some issues with all my cards crashing around 100% (300W) power, even if I only mine with a single card on a 1600W EVGA P2 PSU so I guess I should replace my risers after all these years as I can't see anything else having issues.

So my results might not what others should expect.

I did some test at 100% PL and even beyond which made a much bigger difference but I've lost the results and had to manually restart my test rig about a dozen times and I CBA to do them all over again. Either way, good job sp_!
