I've got relatively pricey electricity. Curious what people have found as the sweet spot between sols and power consumption.

For example, I'm hitting about 400sols for a gtx 1070 at a power limit of about 68 percent. Getting the extra 50-60 something sols for 30 percent extra electricity consumption is not worth it for me.

Anyone getting a better balance?

For all of the 1070 models I've worked with, 110-120 watts seems to be the "knee" where sol/s starts dropping off fast with TDP limit.

This is going to VARY as a "percent" figure because the factory default TDP of 1070 models varies WIDELY - the lower-end ones like the FE and the Gigabyte ITX/Zotac Mini/MSI Aero Mini are 151 watts, many higher-end models are 180, and there is one MSI model with 2 power connectors and an official TDP of 240 watts (higher than most 1080 models and VERY VERY CLOSE to many 1080ti models).

"80% TDP" on a Zotac Mini is the SAME power level (give or take a fractional watt) as "50% TDP" on that MSI gaming model.

This issue also applies to GTX 1080 cards to some degree, and I believe there are GTX 1080ti cards that do not have the same default TDP as the FE cards do but I have not seen one to date.

Sweet spot on the GTX 1080 ti models I've worked with seems to be between 175 and 200 watts, very close to 4 sol/s in that entire range and doesn't start dropping off fast 'till somewhere a bit over 200 watts - but my sample size there is small, 2 "base" model Aorus and a Windforce.

Thanks for your advice

I have the error too where one GPU drops way down to like 265 sol/s while the others are fine. I have to wonder if it's due to a problem with the mining software itself

Sometimes when you get high ping it decrease the sol/s..

I have 2 ASUS and 2 EVGA Superclocked.... which put out a lot of heat. I like the ASUS better.. they look cheaper and smaller but don't put out tons of heat.

... edit... btw. I'm not sure by any means mine is optimum. Maybe someone can post better settings? I have played with the settings for weeks now, and its at a decent spot where it doesn't crash out on me.

Been testing for a few days and I now have an average of 3.20 PEC from 3.0. Performance is the same around 450-470 Sol/s. I guess having a higher PEC is more optimal if you're gonna factor in electricity cost on your earnings. and I agree with you it should be stable.

Hi,

I'm looking for a functionality, where the ewbf miner would disconnect, when the server kicks it out, after it has successfully connected initially.

Currently I'm seeing that the ewbf miner will try to re-connect endlessly, and thus will starve of tasks, even with eexit set to 3:

Code:

INFO: Detected new work: a4f2
INFO 07:23:12: GPU3 Accepted share 21ms [A:4, R:0]
ERROR: Lost connection with the server.
INFO: Attempt to restore connection.
ERROR: Stratum authorization error
Total speed: 0 Sol/s
Temp: GPU0: 42C GPU1: 38C GPU2: 39C GPU3: 37C GPU4: 39C GPU5: 38C
GPU0: 0 Sol/s GPU1: 0 Sol/s GPU2: 0 Sol/s GPU3: 0 Sol/s GPU4: 0 Sol/s GPU5: 0 Sol/s

the use case for this auto-switching on miningpoolhub.com - where the hub 'signals' a change in preferred mining algorithm by kicking out an already existing / connected miner, by rejecting the credentials on a live connection. currently, ewbf miner will not disconnect in such a case.

Hello guys! If you need some stability automatisations please use this (forum.z.cash)(bitcointalk) script.

Interesting.. checking it out now. Thanks

I have the same problem but I think it only occirs when you access the screen of your mining rig. When I open teamviewer, the first GPU hashes only at half the speed because it reserves the other computing power for the screen I think, but it's not a problem that stays 24/7.

I got a problem: when I want to finish mining and I close the cmd window with the red "X", my gpus crash, showing multiple vertical lines on the screen.
This happens only with this miner, both Zcash and ZENcash.
Do you know how to solve this problem?

Does tdp mean top dead power?\\

..edit.. yup.. http://cryptomining-blog.com/tag/nvidia-tdp-limit-nvidia-power-limit/

power limit it is.

"Total Design Power" to be picky, but the term has gotten a bit generic and is widely misapplied a bit in usage - and yes I'm guilty of that myself.

Hehe.. Total Dominant Performance!

I have KFA2 1070 EX and they do the same, but I prefer to run them at 120w with about 440sol and nearly 3.5sol/W

Nice. What's ur TDP and OC settings?

What brand of 1070 are you using and settings? I only get average 3.0-3.1 sol/W, 460-470 Sol/s and temp 64-67c

Can somebody help me with GPU load trouble?

I have 8 x GTX1080 rig.

Miner shows anomaly with GPU1 performance. It can be some number in range 300-500 Sols/s and staying stable til next run of miner.
Meanwhile the Afretburner shows partial load of that GPU (in range 50-95%) that also stable til next run of miner.

https://ibb.co/c94PVm

What's wrong with my GPU or with miner and how to load it for 100% of power? Other GPUs working fine. Changing risers or PCI-e slots has no effect.

With ZEC, you don't have a 100% GPU load all the time, it consumes also less power. There is nothing wrong here.

TY for your comment, all GPUs working with 100% of load, but only one of them has that performance and load anomaly.
When the miner start working I see something like 60% GPU usage in Afterburner and 350 Sol/s for just one GPU, all other works fine for full 100% usage and 530-550 Sol/s.
The GPU usage and performance is keeping stable low until the miner is working. Restart of the miner gives another stable anomaly GPU usage like 75% or 80% or 95% with corresponding performance. I can only try to restart the miner to get that GPU usage anomaly close to 95% to have the performance of that GPU close to max. It's annoining me.
It's shouldn't be like that.

Hi everybody. Since I'm a total noob someone could explain to me how to configure this miner to start? I've got a 1070GTX
Sorry if this question has been made 1k times, I didn't find anything.

Thanks

Depends on what pool you are using to mine. There usually is a readme or listing on each pools site on how to set up the miner to start working with a batch file. For instance, on flypool you just insert what is listed on their homepage into the flypool.bat file and ensure you place your ZEC wallet address in there and then you are good to go.

Scroll down on this page to see what the directions look like
https://zcash.flypool.org/

what you enter depends on your settings and the server you want to connect to. Its pretty straightforward and you should be up and running in a just a few minutes when you decide where you want to run your miner.
