My rig: koeppeloeppe
4x5850 (1550 MHash)
Nice, I find the cable management on the sata disturbing.4x5850 (1550 MHash)
and a waste of such expensive board too.
Jesus,.... or should i say budda
You're in Thailand. Isnt it cheaper and more efficient to build a rack to house all the cards and fans? using wood is fine too.
Heck, i would even have the whole thing watercooled with custom blocks (its so damn cheap to fab blocks over there)

If bitcoin fails I can get out of my set up costs by selling the rigs as mid to high end gaming machines. Water cooling is something I will look into in the future but I doubt I will do it on a large scale.
I have changed my set up and will post new photos hopefully in a week. Thanks:)
Well a wooden rack is a start. Much less prone of accident too
its cheap to build there right?

Nice, I use this board as well. Haven't used the OC dashboard, how well does it work?
plastic.elastic - you should really try making at least one positive post in your lifetime here
I'm not gonna lie to be cool... Sorry
Reject rate over 5% in first 45 minutes -- not looking good... 
That's weird, I don't have that many rejects, I must be around 1-2%... But I do have regular micro-downtimes where my miner falls back to secondary pool.1% to 2% should be expected with how things are set up now.
The 105% should more than make up for this. If you see over 3% let me know. We have issues with FPGA and proxy's for sure. Might be other things as well.
Where is your server located Goat? Maybe, it would be the best to me.
Most ppl in here are from US correct?
Here are some results so far on a dedicated miner:
ASRock 870 Extreme 3 R2.0
Athlon II X3 455
Two cores disabled
CPU voltage dropped by 0.1V
1 stick of DDR3 1066
Seasonic X-1250 PSU (80 Plus Gold)
Windows 7 64 bit
60GB Vertex 2 SSD
All of my dedicated miners are usually using a headless Ubuntu install on a flash drive, but since there probably aren't any programs for Linux that will allow me to change the clocks/voltage on these cards yet (besides what's allowed in aticonfig), I'm using Windows to test this.
2202 Mhash/sec @ 583 watts -- 3.77Mhash/watt (962 mV, 975Mhz/160Mhz)
2106 Mhash/sec @ 553 watts -- 3.80Mhash/watt (949 mV, 925Mhz/160Mhz)
2134 Mhash/sec @ 528 watts -- 4.04Mhash/watt (931 mV, 925Mhz/160Mhz) (one of my cards will not stay stable at this voltage though. The other 3 are solid.)
2060 Mhash/sec @ 498 watts -- 4.13Mhash/watt (918 mV, 900Mhz/160Mhz) (all cards stable)
If you still think these cards aren't efficient, you're drunk. If they were still using VLIW, they'd be insane at hashing. All GPUs show 99 percent utilization. If small improvements can be made to the miner kernels, efficiency will be further improved.
I've got a small external fan blowing on the rig (as with all of my mining rigs). The temps on these cards while mining at 2060 Mhash/sec are 63/64/65/61C. The fan speeds on auto are adjusting to 30/30/30/27% respectively.
All wattages were read with a Kill-a-watt (which makes the measurements on the AC side, of course).

Any idea how this compares on a mh/watt basis with 6970's? I am in the process of replacing a lot of 6970's, and would love to get an idea of how much more efficient these are.
If those numbers are correct, these cards are double in term of efficiency.
Re: 1GH/s, 20w, $700 (was $500) — Butterflylabs, is it for real? (Part 2)
To put things in perspective,
Look at the Raspberry Pi project, its supposed to be shipping in Nov 2011. However, after few delays, they're still not able to ship the products. They just got a contract with a manufacture oversea and will ship the product in Feb. Yet, they dont receive a single negative comment or feedback. Why? simple.... no BS claim, no preorder crap and certainly open to anyone (you can see every single components being used, not some secret BS)
However, ppl in Bitcoin community can be fooled and blind to give BLF some free interest loan. Another fool is willing to do their PR work.

Yes. I think it is unreasonable. It is the way they got into this predicament where they cannot deliver on-spec or on-time.
They took people's money -based upon lies- as capital to build a product (that doesn't exist as of yet) and even with their irresponsible preorders, couldn't finance their endeavor? They are still accepting pre-orders, now for a $25k vapor-box as well. You're telling me they can't find a venture capitalist to kick them a few hundred grand to deliver their products on time? They don't have enough collateral to secure a bank loan?
How can the lead time be the same for a completely undesigned and untested device be the same as one that is already on the production line and due to hit the shelves in a week?

Thanks for answering. So, in a nutshell, your chain of logic is completely non-existent and meanders all over the place, breaking down like a Ford fresh off the showroom floor. That's kind of what I thought, but I had hoped that maybe you had some sort of logical consistence to your constant haranguing, but my hopes have been dashed, sadly.
Sorry if your opinion isnt fact. Just because you think its not logical , doesnt make it so. Who gives a shiet what you "hoped". Do you care if i "hoped" you're retard?
I troll this thread because of pos like you who thinks their opinion is end of all. I dont support such business tactics of BFL's. You can go fuck yourself.
What's the matter, stud? Did I piss you off? Did your little brain overload? Glad you like my avatar, it looks good on you. At least you know what it feels like to not look like a douche. Enjoy it! Sorry about letting your secrets out, but it happens and I am really sorry if I hurt your feelings, little man. Your fragile ego is hard to dance around.
lol i did get under your skin didnt i?
Little man? Judging by your pic, i would never be considered little. But i guess behind a screen, you can run that big mouth of yours.
Btw, is the jokes store sold out? you used the same worlds over and over. If you want my "come" back, scrap your mom's teeth.

Do you think 7970 would be available in Thailand soon?
I do not know. But if its really decent and the numbers work I could just fly to Hong Kong or Singapore and pick some up.
Can you fly to Taiwan?
Singapore parts price is expensive.
Re: 1GH/s, 20w, $700 (was $500) — Butterflylabs, is it for real? (Part 2)
So, when are these expected to ship?
No one here can answer that, except RandyFolds who will tell you 4-6 weeks. Why don't you contact BFL and let us know?
Wrong, one faggot seems to be able to answer that... Inaba.
He got butthurt every time someone bashes BFL.
As for shipment, my ass says early Feb.
Re: 1GH/s, 20w, $700 (was $500) — Butterflylabs, is it for real? (Part 2)
Some nonsense
Congrats, you've just joined Randy on the ignore list.
As if i would give a shiet.
Re: 1GH/s, 20w, $700 (was $500) — Butterflylabs, is it for real? (Part 2)
but I guess you missed his sarcasm.
I hate forums and IRC for that. 
bullshit
more bullshit
If I may politely request that you go fuck yourself. Thank you.No you may not.
I thought you're not feed up with all the BS has been given by BFL

but I guess you missed his sarcasm.
I hate forums and IRC for that. No things to do with forums in this case, you're just too quick to... "correct"
Slow down and you will get it.
Re: 1GH/s, 20w, $700 (was $500) — Butterflylabs, is it for real? (Part 2)
So where is the BFL's bitch? Inaba?
Can you give us an update on how the shipment process is going? Its mid Jan. Time for you to stop sucking Sonny's dick and reply in this thread.

Gonna go out on a limb here, and guess his o key is gone...lol, hence, the 0
except he has 'o's in his posts as well...so much for that theory.
lol
yeah
someone missed the title.
Leakage current is highly temperature dependent, and a good chunk of total power consumption for sub-45nm bulk CMOS processes.
Switching speed is inversely related to temperature -> you can reduce operating voltage to "compensate" the speed gain, thus reduce dynamic and static power some more.
So yes, improved cooling can lower power consumption by a noticeable amount; No clue how much it is at 28nm, but I wouldn't be surprised if it's > 10W for 70 vs. 40 °C on these.

I know what you said is true, my question was to see what kind of expectation from the OP.
Altho its possible to have 40c on all these cards with watercooling, but that means his ambient temp would be damn low. I highly doubt he can save much more than 10w.
Just the default.
OP, explain to me how watercooling would effect power efficiency.
Or you're just dreaming
Or you're just dreaming
Not dreaming, the cooler hardware runs the more efficient it will be and in return the less power will be used. Going from 85c+ load to under 40c load is a huge difference. I saw a nice drop when I went from air to water on my 3 6970's.
Yes.... cooler hardware runs more efficient. But not eligible in a scale we're talking here. What do you expect from 950w? .... 940w? LOL
And no, i'm not new to watercooling.
ps. btw if you want to measure idle power consumption to see how much wattage these cards are pulling just by themselves, you should just remove them and boot your system with live linux. This would give you more accurate number.
