CCminer(SP-MOD) Modded GPU kernels.

[sp_]

I will release a beta of Nexus #7 later today to the Nexus donators.

[Belgiumfinest]

It's possible to to get around 32% increase but the hash/watt decreases as the SP-mod is using much ALOT more wattage at same OC.

This is spreadcoin. Cards wich use more power has the most gain. The 1080ti is up around 60% @ 100%tdp and oc.

I was also talking about spreadcoin. Hash/watt ratio with OC decreases for the 1060gtx 3GB.

Every card need a seperate tuning in the kernels. There is more to optimize here.

Nexus sp-mod private #7 beta
sendt to the nexus donators, please check your spam folders.

I haven't found a block yet with this build. Please test.

- Improved performance on celeron rigs.
- Improved launchconfig on all cards.
- Device selection similar to the -d parameter in ccminer. Seperate by comma.
- Default intensities displayed (0 intesity will turn on default).
- Improved Meter with less fluctating hashrates.
- Improved stability

Thanks for the update but I'm not sure if anyone is using the SP Nexus miners.
Mod 7 CPU usage is higher than that of the other member (majoh) who posted on your thread a few pages back.
Mod 7 hash rate is also about 26 mhs per gpu lower than member majoh's.
Member majoh's finds way more blocks than SP mod 5/6 on the same hardware. I am running 32 1080 Tis @ 70% power limit.

If the both of you can get together and build a faster miner, I will pay good money for it.

I am running 32 1080 Tis @ 70% power limit.

Try to divide the intensity by 3. #5 was broken,#6 had issues with celeron rigs
#7 should be bether

#7 should be bether

I was running with the default intensity of 20. If I lower or increase the intensity, the hash rate decreases slightly.
The default of 20 seems to be best, but the hash rate is much worse than mod 6.

The default is not 20

try to run this bat:

Nexus #7 default intensities:
750 12
750ti 15
960 30
970  39
1060 3gb 27
1060 30
1070 45
1080 60
1080ti 75


Celeron users should run the wallet on another computer than the miner on the local network. Running both the wallet and the miner  can cause disconnections to the wallet.

Intensity of 20 seems to work best for whatever reason. This also holds for member majoh's miner. Tried all the ones above plus many at random between 16 and 70.
Default intensity results in a hash rate which is 8 mh/s lower per gpu.

I think it's because you run @ 70% power limit. Try 100% tdp and 75 intensity. and -500mhz on the memory clock

I will try various other settings and report back to you tomorrow.

I am testing with 6 cards on a celeron 1 instance of the miner. But you need to have the wallet on a different computer on the
network, because the miner dissconnect if the wallet use too much time to retrieve a block.

In a 6 cards rig, you can also run 3 instances of the miner with 2 cards on each instance like this.

start skminer.exe  127.0.0.1 9325 0,1
start skminer.exe  127.0.0.1 9325 2,3
skminer.exe  127.0.0.1 9325 4,5

I have a user who reports 524 MHASH in a 2 card rig. (2x 1080ti)

262.5 MHASH per card

He use an intensity of 60

Verified with max over clocking. Will wait overnight to see if it finds more or less blocks than member majoh's.

I think that was me. I can't get 3 cards to work without crashing my G3258/60 rigs. Max 2 threads per rig or 1 thread and mine other coins with other 1080Tis. Running 5 cards for now and haven't found a block in 4 hrs.

Bitcore sp-mod #2 sendt to the bitcore donators.
Betatestesters on the 1080ti wanted. (0.05btc)

Paying 0.05 BTC for testers, right? 

This algo is really good on the 1080ti. I think it can do 35MHASH. But not tested yet.

Can you post your bat file so I can test the same as yours I am interested in buying this but not before I see what config you are using so I can compare apples with apples

The sp-mod can run at -i 23, while the opensource struggle with -i 22. Highest reported hashrate is 31MHASH with +150 on the core and 100%tdp, but I think it can go higher.
