Greedy conniving mofos.  No wonder the difficulty increased and the bitcoin exchange rate went down.  Wink

I'm happy that you're getting 360+ MH/s on your Asus HD7870DC2-2GD5-V2 gpus.  The Fedex dude was just here a couple of hours ago to deliver two of exactly the same cards that you have to replace a couple of mining-challenged Nvidia GPUs on an old gaming rig.  I have come to the conclusion that generally, AMD cards that are moderately OC'd, usually hashes around 26% of the number of stream processors.  So I figured that I would be getting around 265 MH/s (26% of 1024 stream processors) out of each of these cards.  At what clock are you getting 360+ MH/s with, may I ask?

7850 - I got about 330MH/s - 1200Mhz
7870 - 430-450MH/s - 1215Mhz
7950 - 540MH/s - 1150Mhz
7950 - 520MH/s - 1100Mhz

interesting you post that cause thats about what i get on my 7970 at stock clock

about 530-550mh/s
and 26% of 2048 is 536.48 so its workable Smiley thanks

To add to that list
"Tahiti" Powercolor 7870 Myst cards:
1536 shaders  470MH/s - 1100Mhz  1.06v
                     502MH/s - 1175MHz  1.2v

phoenix2 with phatk2 (modified) seems to be the fastest miner I've found.  cgminer has some cool bells and whistles.  but I just want it to mine, and if it isn't mining, it's trying as hard as possible to mine.

No problem.  I was just being conservative with the arbitrary 26%.  I figured that it's better to aim low and get a pleasant surprise in the end.  Smiley

well conservitive it may be but with amd cards doubling in cores we can extrapolate est hash rate

so a 7990 should be 1gh/s or ther abouts if someone can confirm that it would be cool.
wether this is relevent with all the tweaks and such people do is besides the point
its data and hence good.

There's an error in the new account activation e-mail, it's pointing to www.mining.bitcoincz/accounts/ instead of mining.bitcoin.cz/accounts/.

Wanted to echo the request for an addition to the "My Account" page that displays your 24 hour income stats.

I miss that since moving off of BTC Guild.

Echoing the response: What is wrong with https://mining.bitcoin.cz/stats/graphs/ "Your daily reward"? Why not use that? Is there any particular reason why you are interested in the last 24 hours as opposed to last day?

Thanks...and please see "Edit" to my original post (eyes too slow, fingers too quick).  Anyway, are those clocks sustainable?  I imagine that you must be either in a cold region or in a very well-cooled data center.  The only time I get up to such clocks is when I try to do a quick benchmark...and during winter...and then it dies.

Very stable and its *usually* hot here - may have to drop clocks further into summer especially the ones at the office over the weekend when they turn AC off and it hits 100F+ outside.

To all those who pointed out my guiminer problem was because I had all three miners pointed at the same gpu, you were right - I was
smart enough to set the GTX 480's up correctly but forgot to check the same when I cloned 2nd & 3rd gpu from my first 7870 miner.

guiminer connects to stratum.bitcoin.cz:3333 ok, and all three are putting out 360+ MH/s.

7950 - 540MH/s - 1150Mhz
7950 - 520MH/s - 1100Mhz

That's what I've been getting returned the 7850 now running two 7870, two 7950.
Thanks...and please see "Edit" to my original post (eyes too slow, fingers too quick).  Anyway, are those clocks sustainable?  I imagine that you must be either in a cold region or in a very well-cooled data center.  The only time I get up to such clocks is when I try to do a quick benchmark...and during winter...and then it dies.

FWIW: I am running a 7870 and a 7970 in the same PC. They are running from guiminer with just -v -f0 and -w 128 or 256 flags, but I set the clock performance from Catalyst Control Centre.

7870 is giving 430MHash/s at 1170/1200 engine/mem, with fan set to 60% and power -5%. At engine 1200 it crashes fairly quickly.  Runs at 66C, VRM1 at 71C

7970 is giving 645MHash/s at 1125/1000, 60% fan, -5% power. Runs at 67C, with VRM1 at 88C

One side is off the computer, the PSU is sitting on top, and it's in the cellar where it's nice and cool. Plus we're about 700ft/210m above sea-level, in a rural so that's generally less warm all round!!!!

You can get over 700 with a 7970 easily. I have 2 in the same box at 700. But one is running at 68C and the other at 80C. I can push them to around 710 with GPU clock at 1200 but it gets unpredictable and unstable.

ive heard that you can underclock memory below chip speed on 7970,
but i cant find any stable points can anyone list stable oc and uc settings for stock cooling?

I'm undeclocking memory at 350 with MSI Afterburner prior to starting my mining. You cannot do it with cgminer.

You must modify the Afterburner config file for this to work. Can't remember the details. Check in the Google machine.

Actually you can underclock with cgminer - e.g.

cgminer -o http://pool:port -u username -p password -I 9 --auto-fan --auto-gpu --gpu-engine 750-950 --gpu-memclock 300

see this thread:

https://bitcointalk.org/index.php?topic=68793.0

[EDIT]

I find it crashes less if you don't use afterburner (or other radeon ati overclocking apps) - just overclock for bitcoin with cgminer params

Any one else notice slush's pool luck is proportional to BTC price - when pool luck is low it's a good time to buy BTC and when pool luck is high it's a good time to sell. Uncanny.

See, yesterday BTC was really low when pool luck was really low - now BTC is rising again as Slush's pool luck is high - conspiracy theorists fill your boots...

 Because it's on another page entirely.

 It's just good feng shui having it on the accounts page as "Estimated 24 hour reward" or something similar. We would then be able to see all our individual workers' stats, namecoin and bitcoin earnings, along with 24 hour estimated rewards without having to load a separate page altogether.

 One could ask, "If that data is already available on the Graphs page, why not include a relevant data-snippet on your accounts page ?"

My last two rounds are showing much lower than normal payouts, It's probably just me being unlucky, but I thought I'd check.

Anyone else seeing this with their's?

17838 and 17839? I noticed connection problems at the end of both rounds and that costs. But it's all part of the lottery.
