I just realized my 290's GPU speed do not matter on Zcash.  I dropped them from 1050mhz down to 800mhz, with the same hashrate, and A LOT less power draw.

 R9 290 isn't a good ZEC choice anyway - they would be making more on ETH despite ZEC's recent price jump, abet not by a wide margin.

 In my recent testing of Claymore 12.4 on a pair of my R9 290 vs a pair of my R9 280x the 290s were just a very LITTLE faster on ZEC - but the 290 is right around DOUBLE the hashrate on ETH of a 280x.
 It would take a R9 290 being over 30% faster than the R9 280x on ZEC (400 sol/s vs 300 per card) to match the profitability of the R9 290 on ETH - but I was seeing less than 350 per card out of the R9 290s.

 Just to add insult to injury - my R9 290 have been bios modded via TheStilt, the R9 280x are pure stock.

 Better speed in miners actually DOES help some - for those that change over quickly.
 Some folks take a week to change, some have big enough farms it might NEED 2-3 weeks to get them switched over, some might only check once in a month on new stuff.

 It's not a significant help long-term though as folks WILL get moved to the newer faster stuff.

 Part of it is comparing the current NVidia "started at the HIGH end of the lineup and working it's way DOWN into the mainstream" vs AMD "start at the mainstream and work it's way both up AND down from there" - with AMD not releasing it's first high-end cards 'till this June with the first VEGA cards.

 As I recall, the best cards AMD has at this point on ZEC are the old Fury/FuryX/Nano series (and the Pro Duo, which is basically a pair of Nano on one physical card) - which are a full generation behind the RX series on process node and tech and suffer as a result.

 Based on the "preliminary" and "estimated" specs I've seen about the "Vega Frontier" (same core count as the Nano/FuryX but clocks 50% or more higher), the Vega cards should at least be able to argue well vs. the GTX 1080 and likely the GTX 1080Ti on ZEC hashrates.


 Right now though, the only FAIR "same market segment and pricing" competition is the GTX 1060 varients vs the RX 470/480/570/580 (the 1050Ti / RX 460 and down don't do enough hash to justify buying them JUST for mining with).
 That's pretty close when you factor in that the 1060 clocks quite a bit higher but has a MUCH lower core count - enough so to indicate that the ZEC algo works a little better on NVidia architecture *OR* the NVidia code in current miners is a little more efficient *OR* a bit of both.

Yes but for example in the eth taking the 1080ti all the rest loses in the consumption / income for amd
All previous series consumes a lot of energy so for me it's not worth it and its value in the BR is high too high to buy 3 rx 480/580

Eth miner can be improved past Claymore's AMD GCN ASM Ethash kernel. First, you need to make the damn thing stable, though - he seemed to see others using ASM, and decided to himself... but raw speed matters little if the GPUs/rigs keep dropping like flies. THEN focus on speed.

Whats not stable about CM miner?
You mean it should work better on OCed (pushed to the edge) rigs?
Asking, cause I dont have any problems on my hardware, but I am running mods + underclock + undervolt.

Can second that. Obsessed with efficiency, I run all my cards, even Nitro+ versions, at ~ 26.5 mh/s and they have been rock stable for months across several versions of claymores.

I've one 470 and one 280x. Should I mine ZEC or ETH?

Been running my 470 4G's at 31.5Mh NOT using claymore and it's been stable as a rock for a few weeks.
And guess what. No fee



Same for my Nitro 480's, 32Mh rocksolid.


The thing is, Claymore made it so that my grandma can turn on a computer and start mining. Damn good business model, gotta give him that. And to be clear, nothing wrong with that!
But comon, where's the fun in that?

Yeah Sgminer is a bit more complex, you need to do some things yourself, but if you know what and how, you can top claymore's (reported) speed and then some.

Again, what Claymore has done, is made mining simple for everyone and turned himself into a millionair while doing that. Kudo's to him.

What i do dislike is the fact that a lot of "his" idea's aren't really his idea's. Exactly what Wolf is trying to point out.

Anyhow, enjoy while it lasts.

Care to explain why your average readings are close to "usual" 470 values of 26.xx?
Also HW?

If you look in the top right corner, you'll see that it was only running for 2 minutes, the avarage speeds were only at 26+..

The HW errors is absolutely normal. Nothing wrong there.

I seriously cant tell right now if you are trolling or not
Anyway I guess this could be confirmed only by pool side reported hashrate, those HW look fishy to me.

That's exactly what i mean....

95% of everyone that's mining these days are using Claymore's miners. 99% of them have never used alternative software.
So basically having no idea how other miners work/report, etc..

Those HW errors are perfectly normal.

I'll show you an example of the log.

[09:17:10] [THR0] GPU0: invalid nonce - HW error

So GPU0 had an invalid nonce which resulted into a HW error.
It's not that the GPU is having real Hardware issues, it's just a wrongly submitted share.

Pool side avarage is 246Mh at this moment.

I have used Claymore before and the avarage pool hashrate is in no way even close to the reported hashrate. Hell, even the current hashrate is almost always a lot lower. (of course it is, fee..)

Look, this is a personal thing, i prefer to use alternative software that is faster and in my opinion more stable.
Whatever you choose is up to you.

And no, i'm not trolling.

No worries, I am no guardian of CM or his software, was just curious about your results.
Might play with sgminer in the coming days

Interesting though that this is not counted as a reject.
I always thought HW are shares that did not validate on CPU, hence GPU made an error when calculating it.
I remember back in the day we always wanted this to stay at 0, otherwise we were loosing shares and it was more efficient to run at lower h/s, but with 100% of valid shares.

470 - ETH, 280x - ZEC.

Help me examples of full command line settings for flypool

In version 12.5 there is a speed advantage ? Can we use the version 12.4.

[flekkelek]

I didn't notice any speed advantage, so I guess you can use the previous version, if your cards are stable with it.

12.5 is a slap in the face  with a big F U to those saying he's not releasing new versions and to lower his fee

The fee is still 2 and 2.5%.
