Hello again sp! I successfully launched nexus miner and some surprised... Very high cpu usage  - maximum 4-5 1080ti's for 6700k with 4.6 ghz. Tested with 1060 and 1070 too. Do you planning to reduce this cpu resource consumption?

Maxwell @80% tdp opensource:

Yes. The gtx 1070 should do 30 Mhash with a proper implementation.

I did in release #5. but the fast blocktime in the nexus algo made it find less blocks than before.

[du44]

I'll pm you, because donated 2 days ago and have only 6th version.

I have sendt you number #5 with the cpu fix. This is the fastest miner, but users get less mined blocks. I am working on a fix in nexus #7. Same bug in the Mojo release...

Thanks for your work, but it  helped to run only one 1060 6g on pentium g4400 with 85% usage, in other systems i haven't seen any difference. Hope in 7th cpu can breathe some lighter

so sp, apparently there is a miner of djm34 that do 24Mh with a 1070 on xcn, can you compile it please? this coin is very profitable with that miner

where is it? github?

look in your thread there is a guy with 24MH, he said djm34 0.0.3 https://bitcointalk.org/index.php?topic=1801595.1460

That was with 2 1070s.

oh you are right, i missed the two thread started thing, then it's slower than my 16+Mh on the open source

You also get about half the coins estimates show for XCN. XCN emission is actually pretty low so it's easy to over saturate the network.

382.53 is working

ye, 13h straight with 382.53
2 blocks found (6 gtx 1070 working)

95 tpd
100 core
400 mem

avg speed of gtx 1070 == 8.3 khs, I can make 9 khs but miner will crash every 5-10-15 min.

24h spreadcoin report:

3 blocks, eqv 12.4 coin = 14.8$ current price
Network hashrate and difficulty rising too way fast so I not sure that miner will payback, cuz I still need to find 27 blocks more to do that.
Bad luck

Now using x7 gtx 1070
85 tdp
100 mem
-500 memory

to avoid crashes.

7*1070 Luck!!!  17min:3 blocks

Good profit in Nexus with the sp-mod now (0.05btc). The Nexus blocks are divided in three.

1. POW primeminer
2. POW sk1024
3. Staking.

When you calculate the profit you need to remove the prime and stake blocks.

Got the Spread and Nexus mods for my 1070s, but the speeds shown on the front page don't seem realistic for a typical setup (9.3 Mh on Spread / 160 Mh on Nexus). I'm running systems with H81 Pro BTC, G1840, 4GB ram, EVGA G2 1300 and different brands of 6x1070 with windows 10 and 382.53 drivers.

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

Nexus gives a maximum of 820 Mh per 6 GPUs even with overclocks (100 % TDP). But the big problem with this are the crashes. I can't get it to work for more than 5 minutes without crashing the system even on everything at stock. I'm using the default config that came with the miner (only changed threads to 6) and I even tried to lower the intensity to 40 but it still crashes after a few minutes. Anyone else having this problem? Honestly, the crashing, real speeds and not answering PMs are leaving a kinda shitty taste in the mouth for purchasing the miners.

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.

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

Have the same problem with spreadcoin sp's miner. At some point it starts showing enourmous large hash rate and stop actuall mining. It's ok for open source miner, but it's not ok for paid miner, shitty taste is real. Virtual memory +64 Gb, +80 core, +450 Memory.

The same if I use any OC settings.

Zotac gtx 1070 Mini
Zotac gtx 1070 AMP

I can't get 9+ mhs stable.

i think 16.5MH with a 1080ti overclocked is possible, yeah i was right, just tried...

[kapsel]

I'm getting roughly 7.5 mh/s with 1070 on spread +180 core +400 memory, however running low power at 65% tdp since my power is pretty expensive, I'm gonna test for highest efficiency settings soon.

Test it for 1h, will it crash?

I can't get any of my TI's stable at that rate. Currently best I've got is 14.5 @ +150/-500

rise the mem to 300 and tdp to 80%-100%
