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

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.

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! ^^

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

Thank you!

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.

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 ?

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.

Do you think this mode can damage GPU?

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

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

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 ?
