GTX 1070: 315-325 sol (Windows 10). How to receive 360 sol?

EWBF please add the ability to run multiple instances of the miner (or threads) when starting the miner. Adding one extra instance increases hashrate by +10%.

Try it yourself, launch two instances of the miner and look at the combined hashrates and GPU utilization.

already done memory +600 (stock 270-290 sol)

[Psynthax]

Dont know then.. I get 350sols/s with +100 core and +700 memory, with latest version

Any specific 1070 model? I consider buying founders edition or inno3d iChill X4 8GB. Which one would you choose?

[Psynthax]

Those are gigabyte g1 gaming with samsung memory

If I need to choose between those two I would buy inno3d iChill X4

Any other results on v6? I seem to be getting slightly less performance on 1070. Will have to test more after work.

I had it just stop mining on 2 pcs.. No error.  When I clicked back inside the command prompt, it started again.

so no reason to upgrade to v6 only bug fixes? i'm waiting for the speed increase, i know it's still possible, my gpu usage, ranges from 90 to 95%

@EWBF:  What error 46 mean?

"CUDA devices are busy or unavailable". Use latest version of miner or reduce overclock.

I see, but what is better to downclock, core, or memory?

[jiggytom]

Pool is reporting a slightly higher and more stable hash rate though.

I have a friend with gigabyte gtx 1070 g1 gaming , with power limit 70% mem clock + 100mhz gpu clock + 50mhz , have only 295 sol .

Version 6 .

Any settings for boost is appreciated .

mem should be higher, around 400 at least

this is my: 55%, 150 core, and 400 mem, but you try 500 or 600 mem, it should do 323 sol with 100 watt

My friend with + 150 mem have crashed , 70% or 50% PL have same problem . I dont understand why , i think micron memory or bios .

for Zcash it's better to OC core, the memory OC doesn't do alot, set it around +600 but core around +150, also for micron based memory GTX 1070 cards, please check that you are @ the latest bios, most card had the default nvidia bios bug with the micron chip that was doing some voltage instability for memory, it was fixed by card manufacturer bios when fix was released (evga, asus, gigabyte, and so on) and last remember to give a little bit more juice to the core to make it stable. (~15-20% should do the trick).

Also take your time to manually OC each card of your rig, some will always perform better than others, will help you grind a few more sols there & there and achieve best stability

im @ the moment in my latest configuration

6x GTX 1070 EVGA FTW - Drivers 376.19

Core +150 (real core ~1870Mhz)
vCore +15%
Mem +675 (real core ~4470Mhz)
TDP 50% (~91w per card on nvidia-smi, 692w on wall)

Pushing around 1990 Sols/s (~331 sols/s per card) on average with about 0.15 % reject overall.

Happy mining

nicehash dev sad they will break 400sol/s on 1070 in next release

Yeah I hope EWBF can match the speed, I hate being locked on nicehash

are you sure about the 692 at the wall with each gpu doing only 91, your system is sitting at 150w? seems too much, most likely your gpu are consuming more or the the whole wattage is wrong

There is a difference between what nvidia SMI is showing you, and what you get on the wall, because your PSU isn't 100% efficient, i have 2x 80+ gold 750w PSU's, @about 40% load each so even @ maximum PSU efficiency it's about 90% efficient (@50% load) so nvidia SMI show 91w, it means for each cards about 91 + 10% = ~100w @ wall counting PSU efficiency for each cards, so system+fans are more sitting in the area of 80/90w, starting wattage @ wall is about 130w, before any mining. Guess i should have mentionned it was nvidia SMI mesurements. I posted a screenshot before showing it, will edit my post.

thanks for the tip about updating bios on Gigabyte Micron boards.. i had old bios and i couldnt make more that 270 sols with this miner.

I´ve just updated. Lets see if theres any change...
