Hey OP do you have a kill-a-watt you could purchase locally.  If you are in the states Home Depot and Lowes carry them.  If you can find one locally I am sure we could get together the 3 or 4 BTC to get some accurate power readings.

The kill-a-watt brand doesn't appear to be commercialized here in europe, and I've been searching for an equivalent device locally each time I've had a chance to head out to a store for the past couple of days, but no luck so far.

I also took a stab at modifying DiabloMiner and managed to get it to use 16component vectors, which is what GCN is supposed to be tuned for, but performance isn't what I expect and its really hard to profile/debug the tahiti since I could not find any development tools that specificly support it yet.

Wait wait wait. Are we sure uint16 is such a good idea? Last time I tried >4 (which was before 2.6, btw, I haven't tested with 2.6), it would crash in the compiler. Also, does anyone have a count on the number of registers per CU? There might not be enough registers to handle that.

Also, check some of the larger -vs, -v 40 is two sets of uint4 and -v 44 does three uint4s (unlike cgminer, -v 4 does two uint2s).

I'm having issues keeping my 2nd GPU busy.  Huh

Using the above method with the updated miner script for 2.6, I'm able to keep GPU1 at 99% utilization, but GPU2 bounces between 91-98% on my graph. I've put both on their own CPU to see if that would help but it doesn't seem to have an impact.

GUIMiner Settings on both:
-k phatk AGGRESSION=12 FASTLOOP=false VECTORS2 WORKSIZE=64

Has anyone tried the above with multiple GPU's??

Just switch to DiabloMiner or cgminer already.

That means they had no value to begin with. If BTC dropped to $0 every time I sold some, I wouldn't bother with BTC to begin with.
Sure it would drop to zero if you obtained all the coins from the profits of having a Massive percentage of the mining power, and dumped them all at once.

Yeah, but whats the difference between him doing it all at once or all of us doing it all at once? Do we even know how much he got? If it was less than 10BTC, hell, that just paid for the server for a month or two.

(because large parts of the chip shut off).
I know that the shaders are used to do the hashing, but is it possible to utilize more of the chip, even if it were at dramatically lower efficiency?

No. I already tried to abuse the texture/memory fetch units, but couldn't figure out a useful way of doing it. Its all fixed function hardware and its not particularly interesting for what we do. Although, I may go try that again, SDK 2.6 seems to be a much better compiler in some areas.

But not to the extent that is being claimed. The way merged mining works is when I give 400 mhash to the pool, that 400 mhash goes to Bitcoin AND namecoin AND whatever else without diminishing the original 400 that went to Bitcoin. He can merge mine 9000 other alt chains, and I still get my 400 mhash worth of Bitcoin shares.

But are you getting your 400mhash worth of altcoins? No, he is keeping them. Lame.

That implies said altcoins actually have value, of course. He could setup signed message shit for the rest of the alt chains just like he did for nmc, but the other chains simply have no value.
Some of them did have value, until he spent them on an exchange and reduced said value to nil.

That means they had no value to begin with. If BTC dropped to $0 every time I sold some, I wouldn't bother with BTC to begin with.

You think it will be 200 watts w/ a 20% overclock?  I wish the OP had a kill-a-watt.

Thats at stock clocks obviously. I don't know what the mining values will be, all the cards draw less than their full wattage at stock speeds when mining (because large parts of the chip shut off). I imagine 79xx may even get a larger efficiency boost due to this because of AMD's work on power saving, but without a killawatt test, no one knows.

...he genuinely does seem to believe that whatever other things he does with his pool are irrelevant to miners so long as they get their Bitcoins.

I can't quite agree with him, that's a blatant breach of agreement.
Miners mine at Eligius with the assumption that their hashing power is being exclusively used for Bitcoin (and since merged mining was introduced, Namecoin) mining.
Any other usage of the hashing power is simply unauthorized.

Please think the situation over once more Luke.

Incorrect. There was and still is no agreement to provide Coiledcoins. There is no agreement promising not to use the completed POWs for other calculations besides those promised to the users.

Technically there doesn't have to be. Every additional merged mined pool does not decrease the hash power used on Bitcoin. Luke merely should add the ability for users to acquire the output of the merged mining and it legitimizes it.

Complete disagreement with you here.

Luke should made it clear to his users what he's using _their_ computing power for,
which has absolutely not been the case, and his double-using his pool's computing
power via merged mining is the only explanation possible (unless you believe that
the redneck lowlife actually has a couple of TH/s of computing power hidden in a
shed in his backyard).

If I rent my car to someone, I'd like to know if he used it to attack a bank, independent
of the fact that he's paying the rental fee: I'd be rather unlikely to rent the car a second
time.

He is abusing his users and betraying their trust, pure and simple.

In the UK currently :

5870 costs 170 GBP and gets 440 mhash/s so about 2.6 mhash/GBP

7970 will cost rougly 430 GBP and get 666 mhash/s so about 1.6 mhash/GBP

Thus, the 5870 is still much better and you can also get a 5970 that gets 850 mhash/s for about 400 GBP.

Power figures ?

7970 is going to be 200 watts I believe, and the 5870 is 188 (both at stock watts). This is where the 7970 suddenly shines. Even if the 7970 is 250 watts, thats still a jump in efficiency.

LOL. We are doomed. Why all the signs of the antichrist over in the BTC world ?

$6.66 prices
666 hashrates

What is the meaning ? Grin

How about you get to share that 7970 with others through a pooled fund or something so we can get most optimizations done as a community ?

Because its too difficult to physically ship the card. There also is maybe three people in the world that would benefit from this, and one of them quit working on GPU miners altogether, and the other can probably afford to buy one straight out. Seriously, there simply is not that many people in the world that understand mining well.

6990 is dual GPU so has total of 3072 shaders gets about 800 mhash/s using two cores total.
7970 is single GPU so has total of 2048 shaders get about 666 mhash/s using one core total.

Get some sleep dude and stay off SR !

This.

According to this thread https://bitcointalk.org/index.php?topic=56630.0 someone is cracking 568 MH/s on a mildly overclocked 7970 already.
650mhash/sec now

Nope, 666 now.

Why is it this is the ONLY thread on the mining subforum that gets reported to me every day? Get a life, damnit.

Because the other thread got censored by a rogue mod...

Lets ban ALL the trolls!

You could have gotten more than 4.75 for the BTC! 

Well, yes, we know that now. Hindsight is 20/20, and no one expected BTC to hit $7 out of nowhere.

where's my credit for .00001 bitcoin?

maybe i got the decimals wrong..... sorry =/

There is two for 0.000001, both are in the current total.

Thanks a lot, though. Every btc counts.
