does -x 40 work on the 1080ti?

It works but reduces the hash to ~14Mh. Even with -x 1(3Mh) on the main card the pc is completely laggy/choppy and unusable.
I have no problem running EWBF with full speed and being able to use the pc.
Is the nexus spmod similarly laggy?

1080ti @ 1911/5130 and 5152 (identical cards need different mem speed for that timing strap sweetspot I guess).

The SM Count on the 1080ti is 28. Could you try -x 28 or -x 56?

Nexus:

Did you add 16gig of virtual memory? Try to run with a lower intensity.


Did the (test_750ti.bat) work?


rem ip port threads timeout intensity
skminer.exe  127.0.0.1 9325 1 10 47

intensity of 47 is abit high. Try to reduce to 30.

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) but it does the same system crash after a few minutes (sometimes after seconds). I've been playing with the miner whole day now and I think it just uses too much CPU for 6 cards to work properly. I tried to run it with 1 card, the CPU load was around 70 % and it didn't crash the system but came up with an error "can't get block height" or something in 15 minutes. This causes a popup box and the miner restart loop doesn't run till you manually close the popup. I didn't shoot it up again but I think it won't crash the system with 1 GPU. However with 6 GPUs the CPU load is 100 % and I can't even open afterburner because the PC is so laggy. Seems that this miner doesn't work with low level CPUs with 6 GPUs or has anyone succeeded running 6 GPUs stable with G1840-like CPU? Why does it stress the CPU so much anyway? I would love to have a fix for this or a refund if the CPU is indeed limiting the miner because that isn't mentioned anywhere and I can't use it as is.

On spreadcoin I could only get a maximum of 9 Mh per GPU even with overclocks (100% TDP).

I get 9.3MH on the gigabyte gtx 1070 g1 gaming with oc on both the memory and coreclock.
f.ex core: +150, memory +500


 On the 1080ti you can try to reduce the memory clock -500 and increase the coreclock. The highest reported hashrate from a user is 9.6 MHASH on the gtx 1070 and 16MHASH on the 1080ti

What TDP? Kinda misleading to market the miner doing those hashrates if you got them only with big overclocks on a good GPU. The opening post makes it look like those hashrates are just normal stock rates that you get off the box. I've got a full rig of 1070 g1 gaming cards and they wont overclock on core past +50 on 100 % TDP without the miner going crazy with ridicilous high hash numbers. I actually tried tweaking this on 6 different 6 GPU rigs (different brands) and couldn't get any of them working so all the GPUs would be over 9 Mh.

Nice. new record

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?

[sp_]

I've got a full rig of 1070 g1 gaming cards and they wont overclock on core past +50 on 100 % TDP without the miner going crazy with ridicilous high hash numbers.

On 100% tdp these cards are pulling 185Watt. The 4pin power adapter only deliver 150W. so 35W is pulled from the mainboard. With 6 cards in the rig you need at least 1300PSU gold rated and powered risers.

@boerse29, how many blocks have you found last 24h?

[dimafatality]

24h spreadcoin report:
3 blocks, eqv 12.4 coin = 14.8$ current price

24h more:
3 blocks, zotac gtx 1070 x8 now, avg 8.5 mhs per card. Huh.
12.38 spr * 0.98$ = 12.13$

Gonna test miner 1 day more and forget it as a terrible dream.

[trobnor]

11 blocks on first 24h on 5 1080ti's
asus turbo core + 150 mem -502
running at 15

Most shit coins are like, that, unstable network with ULTRA crap wallet... they have few or a lot orphans, also luck can be a bitch...... but be sure lots of crap alts are producing a lot less then what a math/calculator says!
+ if few-dozen ppl buy SP miner on weak coins diff with just sky rocket, as most if his optimization are on almost dead coins so network is weak

@ eriksin3
I would give you 5% from original price, sorry but more interested in a test then in a profit where is none, also no one will sand first to someone with new account, PM me if interested  
Also you can not ask 50% as sp_ offer "support" and new version "free"

0.025 x 100 is 2.5 btc... why mining... its a better biz to "resell" it... as you point out correctly, too many unknown. lol

Anyone that buys this is risking a virus and also guaranteeing that SP will no longer produce software for us to mine with!

MAJOR DICK MOVE!

[bathrobehero]

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.

[nostrakhan]

I started mining Nexus today with SP's private miner.  Been going for almost 8 hours with 6 1080ti's and 7 1070's.  I haven't found any blocks yet.  Here is a screenshot from my 6x1080ti rig:  http://prntscr.com/ftdndy.  The "Diff" never changes.. I wonder if I'm doing it correctly?  Anyone else familiar with mining nexus, does your miner screen look similar to that?

Isn't this what sp is doing though.

He already posted in Epsy's thread to release an algo that is being worked on so he can take it and "improve" it so he can sell it.

Funny how he has not added any algo's to his version but only after someone else releases theirs.

[shubaduba]

SP forgot to say, that Nexus miner uses full CPU thread per GPU. Miner shows good hashrates, but it is not valid.
If there was Nexus pool, then you would see your actual accepted hashrates.

Actually, with 4 cores CPU like i5 you can mine with 3 GPU maximum. Each miner thread will take 25% of CPU (100% of each core), plus 10-15% more. So with 3 threads it will be 25+25+25+15=90% CPU load. It's not good idea to launch something like teamviewer, Nexus wallet or other miners since system will freeze and lock up.

If you have more than 3 GPUs and willing to use others to mine something else, then you can use only 2 GPUs to mine Nexus, because 2 miner threads use 25+25+15% GPU.
I've tried to mine with 8 GPU's (1200 Mh/s total speed) with manual CPU affinity settings set to use only 3 of 4 cores, but miner did not find any blocks after 24h running.
I have only 2 GPUs mining Nexus with 370Mh/s and found 4 blocks after 24h run, using 2 CPU cores with 65% CPU load.
Other 6 GPUs are mining other coins without issues.

That means that 0.05BTC donation for private Nexus miner with CPU issues same as in opensource miner will make profit only after couple of weeks (if diff/price will not change) unless you have something like Core i7/i9/Ryzen CPU with many cores, because mining with more than 1 GPU per CPU thread will not find any block.

Compare your last found block with http://nexusoft.io/platform/
I had same issue and needed to restart wallet after finding orphan block.

[nostrakhan]

@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
