My second ZEC + XMR+ ETH thread builds info links thoughts and photos.

I'm about to flip my rig for Zcash, especially with Claymore miner comming out in 1 or 2 days.

Might try Genoil tonight ... if I can cash out a card with Zcash I will be happy.

EDIT: BTW I know use the flag -gser 2 for my cards with Claymore, looks like to help with the initialization. I tried -gser 1 but I still had GPU4 not starting (0 mh/s).

I have a new monitoring script if y'all would like it.
It looks for things in the command line like job failed and if a gpu crashes and resets the miner
It not longer resets after so many seconds it only resets if a problem happens like watchdog on claymore

Might be nice to have.


The script I used did not work well.

Right now I run genoil with -g 0. Which gives me 1 gpu per pc and it shares with claymore.

I run Eth claymore with does the rest of the gpus


Result is say 3.5 of 4 gpus doing Eth.

And .5 of 1 gpu doing zec.

It is stable so far.

ill share my whole file so everyone can see what i work with.

the newest genoil miner it has a watchdog built in but i have not tried it

with all my miners now on zcash im making 80$ after power at the current price.
monday tho i made 140$
also a sidenote to know if you have a dual core process that doesnt have hyper threading it will stay under load and the gpus wont be at max mining ability. zcash miners  need more than 2 cores to start and run smoothy it seems

Thanks you so much for the information.
I shut down all cpu mining and gpu hashrate increased way more ...
I lost lot of time and money because of it but now I can try to recover a little ...

Genoil 6 seems to stay stable with nanopool by the way.

you can thank phil
he helped me a lot over a year ago to get started into mining
im just doing what he did for me for everyone else thats needs it

I learned a lot with Phil too ! thanks guys.

Hashrate is better now without cpu mining , with genoil6 and nanopool. Almost no crashes.
Do we have a setting that allow cpu mining without any loss at gpu mining ? (even is cpu mining is reduced, it could be better than nothing)

And did you get more information about how the guy went to 1ks.s ?

[rawbert]

someone on the zcash forums posted 1ks/s on a radeon 6990 card....

That's a malfunctioning card.. all the shares it makes are invalid.

[citronick]

Thank you both for the answer.

I was stupid about the -p , too much headache with the others problems... lol

But still not sur about the zec zec feature, should we try zec zec zec for better results and decrease if it's not stable ?

the -k zec zec zec, just pushed the 6x480 to overdrive (over 200 sol/s) but the rig is pushed to its limits... its hashing but I need to leave it alone... its a low budget ETH rig btw, 1840 Celeron, H81 Pro BTC, 8gb ram, 120gb SSD

Do you think this mode can damage GPU?

Be careful with MB temp Phil.

I noticed on 1 of my 5 GPUS rig running 3 ZEC GPUS and 2 ETH GPUs that MB reached 150°c in a short time.
This temp disappeared as soon as I shut down or eth mining , or zec mining.

I tried it (zec zec zec) in my 2 GPUs rigs and hashrate dropped from 25-30 to 8-10 ... on some RIG (with I5), and made the others one crash (with celeron)

zec zec seems to work.


What do you all use as -work/-w parameter ?

i think it will push the memory controller hard, just like XMR mining.

so driving CPU cycles up is likely

the miner SW needs to take advantage of the GPU core for CPU cycles to be efficient

I think Claymore magic codes may be able to do this since same approach for ZEC like in Cryptonight/XMR miner

Let's see how Claymore new miner is up to the task.

Got it - but fortunately it does not work on my low-end rig at all

Thank you!

Hi Folks,

if anybody could tell me,
how 2 insert Pics in Threads here,

I would give you some "Samples",
of how 2 get a "simple machine" up and running.

... actually a 80% move 2 ZEC seems 2 be rewarded (temporally only, my fear).

,yours PanneKopp

P.S. R9-390 seems not as good, compared 2 a i3-6320 (nor E5-1650v4) - AVX2 matters! ^^

Hello fellow miners... thanks again to everyone that helped me get my first mining rig up and running (4 MSI 470's on a ASRock x99 with i7-6800k.  I've been getting 110 h/s on ETH over the past weeks, along with HDD mining BurstCoin and sporadically CPU mining XMR (although the latter is going to end very soon due to horrible price of XMR).  The rig has been stable for the most part and I do have interest in mining ZEC but waiting for Claymore's GPU miner and CPU miners to stabilize a bit before jumping in and risking down-time on my 1 rig.

Anyway, I am actually looking for some advice on building my 2nd rig, keeping in mind that I want to build it with ZEC mining factors in mind. I actually have most of the piece already, except for the CPU, which is what I want to get some feedback on.  Before ZEC hit, I was really planning to go cheap... likely a G3250 or 3258... maybe even a Celeron G1840.  Note that I am dedicated to LGA-1150 since I am building this on an H81 Pro BTC R2 Mobo. 

However, now I see Phil and some others postings that indicate a "better" CPU like i5 or i7 can add to ZEC hashing power, so I am a bit back to the drawing board. I know that it is early in the game and it seems the CPU miners are still not either 100% stable or optimized, so given that, just looking for opinions or gut feel rather than time-proven facts at this point.

Here's my situation:  I can get an i7-4790k for about half retail price ($170). The low-end CPU's I was considering run between $50-$75... so roughly $100 less than the discounted 4790k.

Here's the question:  how much extra hashing power for ZEC would the 4790k provide over say the G3250?  And, how would those extra hashes translate into monthly $ at current ZEC rates?  I know that it is likely that ZEC price will drop eventually, so mainly looking to assess if I can ROI that extra $100 for a better CPU within the next 2-3 months or so.  I would just hate to build a new rig with a cheap CPU and miss out on the extra ZEC hashes... if, of course, it's a relatively decent bump to use an i7.

[ps_jb]

with i7-6800k. 

First of all - what is the CPU mining speed with i7 6800k?

Second - here is the calculator: https://www.whattomine.com/coins/166-zec-equihash

If you want to mine ZEC with your CPU, make sure it has AVX support. Scroll down to the table labeled "CPUs, related to Intel Core i7-4790K". Anything with AVX (or in the case of newer CPUs, AVX2) will mine much better than a CPU without this support.  The algorithm use to calculate the solutions utilize SSE2, AVX, and AVX2 instructions.

If you want to mine ZEC with your CPU

All I want - to see how many Sol/s i7 6800 can get. As I said couple of post above I need a powerful desktop for home, so why not buy good CPU and use it for mining

[LoneRangir]

I need a powerful desktop for home

There's your answer... 

[ps_jb]

There's your answer...  

And two choices - 6 cores vs 8 cores. And if 8 cores can mine 160 Sol/s - I will build desktop on i7 6950

And I'm curious about this 6 core i7 6800!

Save the money...  Buy an extra GPU and get in the game.  It's gang-busters right now.

Nope

6 rx 480 give me 170 Sol/s (1650$)

What if 8 core can give 120-160 (1000$)?

To be honest I doubt that it can - so this why I need an info
