4x1070 G1, 100%, 0,-502... 420sols .. well done, sp
it´s just a bit slower than nicehash miner rlsed today

Did you try with -i 0 0 (2 threads pr gpu just like the claymore miner) if you have a good processor might give  a boost.

[sp_]

I have uploaded a new version with the cuda dll included.

nheqminer -t 8 -e 2 -cs -cd 0 0 -ct 126 -cb 140
i5-6600k and 1060 6gb giving speed fron ~110 to ~120

What do you get with -t 0 on the 1060 6gb?

~90 with +1800 memory clock (OC in gigabyte extreme gaming)

[Amph]

the only problem i still see is that the hashrate fluctuate too much from 630 sol to 680+, but this was true in any build, so something isn't done properly in the code

[bathrobehero]

Anybody tested it on the 970 yet? 960 is untested. What do you get?

Nice one, thanks!

A 5 x 970 rig fluctuates between 357-388 (so 71.4-77.6) after the initial climb (2-3 minutes). Every silentarmy build I tried fluctuates quite a bit. 130W per card.

Some notes:
- it looks like the -cv parameter doesn't work; it always uses silentarmy (not an issue);
- the maximum card/thread number is 8 (for example nothing matters after -cd 0 0 1 1 2 2 3 3);
- forcing AVX2 (-e 2) even if the CPU doesn't support it (and obviously not CPU mining, -t 0) seems to give a small boost.

The statistics is the average of the shares found in 30 seconds. I should increase this to 2000seconds in the next builds. I use 30 secs when developing to check if the cards trottle and get instant feedback on the speed.

4x970 went from ~300 (zawawawa-r6) to ~340, oc + p0, tdp 85-95%, W7 + i5. Cpu usage max 3%.

i dont find the -i parameter in help.

what´s -i 0 0 ??

Sorry the parameter for 2 threads on one gpu is  -cd 0 0

2 threads per gpu

There is a bug that only allow 8 threads. Will fix it later.

-cd 0 0 1 1 2 2 3 3 will run with 2 threads pr gpu in a 4 card rig.

[giagge]

No have a bug in my release, use -cd 0 1 for 2 gtx 1070 , and have 110 sol for gtx 1070 with 220 sol total .

[sp_]

There is a bug if you use the -cd parameter with more than 8 numbers. Number 9, 10... and upwards will be ignored.

hm...
according to whattomine zec has less profit than eth mining at least for my GTX 970

[sp_]

That's because the zcash dropped another 13% today on a 1MUSD volume

[tbearhere]

Cant get msvs 2015 to fully install on my vista computer   wont run new zcash miner  and im running with old drivers.
But a good increase on windows. Thx sp

[mstang83]

here is the build

Zcash sp-mod #1

https://github.com/sp-hash/ccminer/releases/tag/zcash-spmod1

sp_, you're the man!! Thanks!!!

Yup, it's been that way for days, even with 100 sol it's not worth mining on a 1070 compared to Ethereum, especially Eth dual mining.

But electricity is expensive in the winter.

Run zcash sp-mod #1 with -500 on the memory clock and 55% tdp. Almost Half the power compared to etherum+sia. And a boost in the hashrate compared to stock clocks.

Sp on that tdp do you set it manually in afterburner ?

[sp_]

In afterburner slide the  Power limit to the left

[reb0rn21]

The best would be to use freq/voltage graph and lock desired freq/vol with "L" but problem its only apply to one GPU per rig, so each GPU need to be done manualy
Unwinder sad its designed as that because each GPU have different freq/volt table, which is shame

Also sliding TDP to 60% and OC-ing you can get undervolt but if miner is low GPU usage it gona "boost" as insane so GPU will crash, I would like to see some new OC tool that can define static freq/voltage to all same GPU in rigs!
