  • 708 Mhash/sec on a Radeon HD 6990 (stock clock 830MHz: BIOS switch at position 2) -- this speed has been measured with Catalyst 11.1. Catalyst 11.2 and 11.3 contain a performance regression that downgrades the speed to 683 Mhash/s. However because aticonfig in Catalyst 11.1 does not support the HD 6990, I advise users to install Catalyst 11.3 or later, run aticonfig to generate xorg.conf, then downgrade to 11.1 for operating hdminer.
Very interesting downgrading Catalyst. Using Catalyst 11.3 and Phoenix I get 670 Mhash/s vs. your 683 Mhash/s. Sounds to me that hdminer is only 2% faster, and that the bulk of your performance improvements are in system configuration, and not miner optimizations.

I lowered the price from 400 BTC to 350 BTC.
hdminer is currently the fastest miner for the HD 6990 at 708 Mhash/s at stock 830 MHz clock, compared to Phoenix's 650 Mhash/s, a difference of 9%.

Future reply to the random guy who will reply "but I get 7xx Mhash/s with $MINER when overclocking" -> I said at stock clocks !

The numbers don't work for miners with a single 6990, or even four of them. With 10, it starts to look attractive. If I had 20 6990s, I'd buy without a second thought.

That said, your price severely limits your sales volume to those who are setting up large mining operations. As an example, I would venture to guess that at 35 BTC, you would sell far more than ten times as many copies since it would then be attractive to every AMD GPU user here mining with two or more cards, and to many of them with single cards. I'm sure you've already considered how to price your miner, though I'm not sure you considered it from your potential customers' perspective.

at that volume, it may get leaked pretty quick

His "stock clock" is with 830 clock (ie: switch turned to Overclocked)

No, 830 is not overclocked.
Overclocking with the switch brings it to 880 MHz.

Damn it. Why is it that 50% of the posters in this thread make mistake when comparing o/c vs non-o/c card? This is what I am saying, all comparisons should be done at stock clocks to prevent mistakes and misinterpretations Grin

Just for reference, I get 714 Mhash/s at 830 MHz clock running phoenix 1.3 with VECTORS=on AGGRESSION=10 WORKSIZE=128 BFI_INT. At 900 MHz I get 774 Mhash/s.

EDIT - Actually, that is with the overclock switch turned on. Otherwise, at stock speeds, I only get 668 MHash/s. Could you post numbers for these other scenarios?

As the first post says: with the o/c switch at position 1 (880MHz) = 746 Mhash/s. This means hdminer is faster than Phoenix by 4.5% assuming you did not change anything else (PowerTune settings, memory clock, voltages, etc). Is it the case? Some resident o/c tools automatically changes the PowerTune settings for improved performance for example, even when running at "stock" clock.

Why don't you make a donation-address and say "If I get about 1500 BTC on that, it will be open source"?
Yes it's much, but if more and more spends money on that, this program could be open source in a few months Tongue

350 bitcoins !!! Cheesy Man that's a lot of money 1 btc = 1.20 sterling. So you think your miners worth £420 per license for an extra what 40MH/s lol !!! I think I'll stick to my regular free miners and donate. This is just plain greedy Cheesy Well my opinion anyway.

Yes, sounds about right. Except I started selling in January when the market of interested buyers was much larger.

well, the pool operators do not seem interested, even at 400 BTC.

So far, about half the bitcoin hashrate is in pools. The people inside the pools are far from the 22Gh/s I mentionned earlier.

Even if all the solo miners had 22Gh/s, that would make 13 people who cold actually make money off of this

Currently, hdminer is not redistribuable, as specified by its license. However if a pool operator would have such special needs, I am willing to arrange a special deal.

It is true that hdminer's target market is not the individual with 1 or 2 GPUs. Many of my customers are, or at least appear to be large-scale miners. Of course, I cannot divulge any details.

Ok I get what you are saying... but will people accept the double fee? I guess they would but ya never know. And couldn't someone just leak the miner and kill that for slush? so there are risks. and would the creator accept that the largest pool shares his miner with so many people with paying more than 400 BTC? if he would then slush should do it... HOWEVER other big pools would probable DO THE SAME in which case, idk if he could even raise his fee.

So atm, lets say slush is getting 40BTC per day (2% fee)

Now if everyone uses this 5% increase miner (I'd like to note that we do not know the increase really. Someone has to try 6990s on the poclbm), The total pool would generate 5% more faster. Problem is with that, slush is a quarter to a third of the total mining power of BTC AFAIK. Meaning bitcoin as a whole will be increased by ~1.32%(if we take 160Gh/s number) , which WILL be translated in a 1.32% difficulty increase.

So while he is getting 5% more, it will be 1.32% harder to mine... ie: 105/101.32= 3.6% more as a total.

so 2000*1.036= 2072 BTC that the pool will generate. Here's the thing, if he keeps his fee at 2%, he'll be getting 1.44BTC a day more, so it would take 278 days to get back his BTC invested in this, not worth it. an extra 1 % would make him pay it off in 20 days, and 2% would need 10 days. If deepbit does not do the same for perhaps 2 weeks, then slush is fine, but if he has competition, it's not a good thing for him!


I would like to know if the creator would let the big 2 pools use it, provided they pay him 400BTC ea.

Not if he locks it down and uses a proprietary interface.
