yep. Im getting around 315 per core overclocked.

Overclocked to what speeds?  I see about 300 per GPU at 810 MHz, but I'm on f=120 right now.  f=1 seems to be worse.

310M @ 825 MHz, 320 @ 850Mhz both @ -f 5.

At STOCK speeds he's getting about 285 per core, so this miner is about 5~6% faster than poclbm. Not worth 400BTC now though

With poclbm I get ~270 m/h/s with both cores at stock speeds. I am not sure this is worth 400 btc.

Are we talking about 569 Mhas/s insted of 540 Mhash/s garated by poclbm? It's 5.3% improvement for 400 btc...

5.4% xD well 5.37 that round up to 5.4% if you wanna keep one decimal, but I'm just nitpicking Tongue

This is making an huge difference having not less than 1Mhash/s as absolute error, due to the presenation of the hashrate, and there is an ~ in front of it.... Oh look, someone just lost the chance to shut up.  Tongue

how much improvement (in %) does this software have? by the replys im seeing, it seems to be very minor, and i think the buyer should lower the price significantly. maybe 20 BTC?

You guys do realise this thread is 1 month and a half old? back when 569Mh/s for a 5970 at stock was HUGE?

hdminer is only ~5% faster than the best publicly available miners nowadays, so in a sense, it is not worth 400BTC if you are a small-scale miner (less than a handful of GPUs). However I plan to implement optimizations soon (have been wanting to for a while), which should bring another +5% improvement or so.

Bumping this thread because I tested it on HD 6990 (see original post for perf numbers).

I actually measured 746 Mhash/sec on a Radeon HD 6990 at "880MHz" (BIOS switch at position 1). This is higher than the theoretical 723 Mhash/s I would expect for this clock due to AMD PowerTune constantly dynamically adjusting the clock which averages higher than 880MHz.

Very few people would benefit enough from a 5% increase to justify paying 400 BTC. I think the only viable business modell is to set up you own pool and lock your client to it. If it really is 5% faster you could take a 4-5% fee and people would still earn more than from the other pools.

There is no "5% increase over best publicly available miners" anymore, at least for 5970, because with m0mchil's poclbm git HEAD version, I get 569-570 Mh/s on stock 725 Mhz (-f 1 -v -w 128, Linux, Catalyst 10.12, SDK 2.1). It needn't to be HEAD, the improved OpenCL kernel was introduced in early February. There are other reports of 560-565 Mh/s for this card at stock frequency.

If mining solo or pool, you'd break even only at 8000BTC mined, if benefit is 5%. Not even Slush mined that much.... He actually only mined HALF of that.

Now that difficulty is over 82K, this would take a long time... Even if we say in a month it will not rise, to do 8000 BTC in a month, it would take 22Gh/s. And this is being on for 24/7 no fault, and assuming the difficulty will stay stable. All this just to break EVEN = 0 PROFIT. 1 month of 24/7 mining with 22Gh/s.

That would take 30x 6990s, divided into at least 8 PC's. Each with either MONSTER PSUs or 2 BIG PSUs. 4* 6990s on 880Mhz stock would take about 1500W alone, not even including the rest of the system.

Noting that, for someone with two 5970's that better miner software would be worth maybe an increase of 20 to 30 coins a month.  So if you charged 50btc the buyer MIGHT get most of that back after two months.  Or you could have sold it for 10btc and sold many many of them.

That's the problem with selling it, there's really no way to set a good price. Running a pool is more work, but he could probably earn 100-200 BTC each day if it really is 5% faster. Slush's pool gets 2000 BTC each day. If he charged 4% or less he could probably get a much higher hash rate than Slush, because both those who already use a pool and those who currently mine solo would earn more by switching.

look at poclbm-mod from bitcoinpool... everyone can use it anywhere.... if he makes everyone in his pool use it, everyone could use it elsewhere...

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.
