Unfortunately my cards (Palit 750ti stormX) couldn't gain suck OC. Which brand are yours ?

It was the cheapest thing I was able to find Palit stormx oc 750 with only 1gb of Samsung ddr5. I was lucky or maybe only 1gb mem and only 512 shaders let the card oc so well under std conditions

[rednoW]

I had old nv driver ,maybe couse of this.. i'll will update.

i will certainly recommend 352.86 driver, it works very good for me ...

klaus_T has optimized lyra2 on the gtx970. I merged his changes to my fork. (+60khash) The performance on the 750ti is the same.

sp - is there a list of the algo that this fork can actually do? ...

is it all in the --help listing and is it up to date? ...

He has forked my fork, so it should do most algos.

A bit off topic but I picked up a GTX 970 (Gigabyte Windforce 3x) only to realise the TDP of this card is not 145W but 250W. With stock BIOS, 100% power target and +160 Mhz core OC it draws 234 watts from the wall mining groestl (which seems to be the hungriest non-scrypt algo) on a 80+ gold PSU. It seems its efficiency plateaus around 40-60% power target limit depending on algo:



That is a 68-75% decrease in efficiency depending on algo compared to stock settings which is huge! This is important when profits are barely above electricity, for example if you pay $0.14 per kwh for electricity, going with yaamp x11 payout figures (which are not very profitable) one of these cards would earn 0.00371 BTC on stock settings while it would earn 0.01652 BTC after electricity at 40% limited power target in a month. On the other hand with more profitable coins/algos like quark, it's worth it to go full speed and overclock because it would end up earning more (0.08967 BTC on stock vs. 0.13118 BTC overclocked in a month). I thought it was quite interesting.

I have the same card and it draws 170 from the wall on Quark. I'm not sure why it would draw 250w, it's the same architecture, unless they boosted the core voltage (the vcore is the same as my other cards). Are you using a wall meter? I noticed there is a lot of headroom as far as the TDP on the cards, but they don't draw that much, at least mine don't.

I tell exact temps, and the only times I didn't report watt usage was when I didn't have a meter. Which was due to two of them melting while being used well under 1300W, while they're supposedly rated for 1800W.

I never added them to my sig, because it's constantly changing, and I don't care to update it that often.

Don't buy a kill-a-watt meter, they break, get a different brand. You can also measure amperage usage with a amp meter which would give you the numbers if you don't want a wall meter. It has nothing to do with you being incapable as much as you not wanting to. Temps don't matter either, watts matter.

The same thing goes with advertising the cost of your miner, that you're selling it, and the stats of said miner. You don't because you want to keep it on the down low and you want to milk people for as much money as possible.

Laziness is a awfully convenient excuse, especially when you'd give everyone a fair chance if you had a thread or a location for your miner where people could actually find out information on it.

I don't sell it to a ton of people, because this would make the people who have paid unhappy - nethash going up and killing their ROI when they've paid me BTC up front is no good for them.

And this is exactly what makes you a asshole. You don't get to act like a elite snob and then pretend you're one of the common folk. By making a handful of people rich, you made everyone else mining poor or go belly up. Low and behold it's the people who make the most money already as well. Go figure some people would be angry when you lost them a bunch of money with your shenanigans.

How exactly do you ROI on a piece of software you make in your spare time? What are you development costs? Where is your company? I hope people resell on you too, you deserve it. Unfortunately they don't do a very good job of marketing either.

If you sold it for $20 or something remotely sane or added a mining fee things would be much much different... or even sold it at all publicly, but you don't and you choose your particular model which fucks a bunch of people because of it.

It's an OC version, should have added (GV-N970WF3OC-4GD). The voltage is 1.212 and with +160 Mhz it boosts to 1476 Mhz.

I measued with a watt meter at the wall. Same card draws 242.97W in a stress test in this review:

http://www.tomshardware.com/reviews/nvidia-geforce-gtx-980-970-maxwell,3941-12.html

So from Gigabyte both the OC and Gaming editions have a factory increased max TDP of 250 watts. Not sure if that makes me happy though. I wonder what a 145w TDP 970 does but it seems most people have the 250W cards.

[pallas]

I don't understand why people get mad at wolf0.
He has always developed opensource projects, along with some private. I do as well. There is nothing wrong with it. Just envious people who want to take advantage of the other people's work for free.
And mining is not for everybody for a long time now... Wake up and realise it :-)

[5w00p]

Yeah, sorry bensam1231, but you are basically whining.

Here is a summary:

bensam1231 - I don't like what you (Wolf0) decided to do. Waaah!

I checked mine and this does indeed seem true. Mine are running at 190w at the wall with a 190mhz OC. Not as bad as yours, but still not as good as my other cards. Also 40% TDP they're pulling 85w and around 10000MH on quark.

They must've increased the TDP limitation on cards due to yield issues (970/980 had yield issues when they first came out). That would explain a lot and also make me regret buying these over 750ti if this is indeed true. Playing the lottery on cards has never been my strong suit.

My Asus cards don't seem like a 145w either, they sit around 175w with a 220mhz OC. Cards always seem to max out around 1500Mhz without a core voltage increase.

I don't understand why people get mad at wolf0.
He has always developed opensource projects, along with some private. I do as well. There is nothing wrong with it.

There is everything wrong with people hiding markets and making back room deals. This single handedly fucked AMD small miners that couldn't pay for his kernels and/or didn't know they existed.

Yeah, sorry bensam1231, but you are basically whining.

Here is a summary:

bensam1231 - I don't like what you (Wolf0) decided to do. Waaah!

Pretty much, I didn't like someone jamming their dick in my ass, as would any AMD miner that spent a bunch of money on cards just to get fucked by him. Most people didn't even know this happens because his kernels were kept hush hush or they're called 'private', when really he's selling them.

Imagine if SP decided he was done with you guys and decided to make his kernel completely private. Improved the hashrate by 3x at the same wattage so all your cards essentially don't make any money and if you want his new miner he charged you 5BTC for it. That means only big miners who have a lot of hash would be able to afford it and if you're a small time miner, you wouldn't and essentially get pushed out of the market since coins use a pie distribution. If someone is using the same card and they have a better kernel, they take your earnings to make up for it.

But yeah, he isn't actually going to tell you he's selling it and you get to watch your profits dwindle into nothingness and wonder why mining has gotten so hard all of a sudden. Wolf0 actually tried to justify this at one point as 'people using graphics cards for space heaters' when I opened a thread on this.

You guys are full of shit if that wouldn't piss you off.

[pallas]

This is childish, come on!
There are FPGA farms with algo ready before coin launch!

bensam1231:
Learn to fackin code then.

djm34, IIRC,  was the one who apparently made out like a bandit when his optimized miners were KILLING everything else available about a year ago when mining Monero.

Do I like that it was him and not me? No, not really.

But,
Do I cry about it in public that he had the skill, initiative, and resources to mine so many Monero in such a short time? No, I don't whine about it and call him names. In fact, I give him credit.

Just because something that another person decides to do doesn't work out in your favor doesn't make them an "asshole."
Actually, I would argue that your whining and crying about it makes you seem like one.

[myagui]

That was not djm34, it was someone else, a group of people in fact - sadly - it was not me...

Well Dave Anderson is the one who outed the whole thing.
Somehow, I though he was djm34. I dunno.

[myagui]

Btw, I really don't want to get caught in the cross fire, but anyhow, I'm all for private miners, in all their forms. However, I'd sooooo much prefer a fee-based system, whereby the miner assigns a % of shares to the developer, instead of some upfront entry fee. This is the one scheme that works for miners of all sizes, big and small.  

As I understand, there's some (GPL?) licensing trouble to make this easily available. A miner developer will need to essentially build a full miner from scratch - not just the hashing portions - in order to properly release his miner as closed source, thus embedding a fee and protecting his source/work.

Sidenote: I'm actually inclined to think that SP_ has done more for the community at large (with Quark), than for the people that bought his miner. Going by the hashrates advertised and/or thin markets, don't think the private XMR or SPR versions will have represented any meaningful return. Maybe just my impression though, I'm not trying to pick on SP_ or anyone in particular...
Heck, maybe it was very much worthwhile for people with large farms (as they bought the miner for the same price as any small timer on a single gaming/mining rig).  

[antonio8]

@ bensam1231

Just a thought.

This is sp_'s thread about his miner. If you have an issue with other devs (which I don't understand your beef. You don't like it go code or don't use said dev's miner) you should pm or start another thread.

This is starting to clog up this thread with your personal issue.

Unless you are using AMD cards (which they have their own thread) There is no need to call out wolf0 as he is not dev'ing for Nvidia (this thread). I don't get why you are even attempting to start issues with him. He as every right as you do to make a living however he chooses.

So please, enough with it in this thread.

PS. To myagui's point on the fee based miners. I still think it is a good idea. I understand someone might come along and try and reverse engineer it but I think enough people might still respect the dev to still use it. Rumor was claymore did pretty good with his. Even though someone took his fee out I still used claymore's out of respect for what he did.

Not sure how many people used djm's (I believe he had the one for one coin) as I never heard how well it went with it.

Enough of my rant and back to topic.

[sp_]

I don't think the next kernals will be Opensource. I try my best to keep high standards, but you have quality coders like djm34 and wolf0 who push the standards.. The current quark implementation is good, but djm34 hash pushed it more than 10% faster after a few afternoons of work. Take a look at the neoscrypt kernal. It is really good... 300% faster than the opencl is insane...

I added another 50% by rewriting the blake implementation. but the sp-mod is only 7% faster than the djm34 mod.

and the Wolf0.. He is good. He is like me when I was 20..

[Nubminer]

are you really getting 10,000 MH on quark out of a 970 ?? or did I read this wrong..

I only get 10,000 KH per card how are you getting double ??

GIMMIE !!
