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

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:

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.

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.

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.

And mining is not for everybody for a long time now... Wake up and realise it :-)

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.

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.

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

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? ...

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 ...

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

Is this with Sp released ccminer?
yes. #52 std

With SP@52  1350 core /1400 mem 750k hashing what's wrong in my set u?

Hmmm it'd be nice to get comparable rates out of a 970. I think this is currently the most profitable algo (more the quark) based on your hash rates for you 750ti if it worked properly for everyone else.

memclock maybe to low ... try to increase, lyra algo doesn't stress to much and allows to use frequencies above stable )))
Also check in gpu-z if your card is not throttling due to tdp ...
Already edited to bios to 65w TPD,According to Gpuz Just %30 tpd.. i'll try to incerease mem clock but i'm not sure that all cards can go to 1600 mem clock,Most of cards with samsung vram some hynix , anyway i'll try ans see  Smiley) Thanks for your help.. I had old nv driver ,maybe couse of this.. i'll will update.

Thanks , mates , I couldn't get more than 820kh/s with my 750TIs.
Which clock do you using with it..
1510/[email protected] fan 65% temp 51C (room temp 26C)
