first, I LOVE the idea of your custom cases.. You've put a lot of work into these, and they're well done, well thought out, and not ugly!! I'll probably be buying at least 1-2 of your cases.However, In order to run 7 cards, don't you need to be using the x1/x16-to-x16 adapters with power tap like these..   to avoid pulling too much juice from the motherboard? at 7x$25, you've added $175 to your build cost, which removes some of the $$ advantage of going 7 cards wide? You're already buying two power supplies... am I missing something?

I tried cgminer on a couple of my boxes last night and woke up to find 3/4 GPU marked as DEAD on one and 2/4 DEAD on another. Trying to restart the DEAD GPU doesnt seem to do anything on either machine (restarting the ones still running did seem to restart them OK). Both boxes have been running for weeks using poclbm without errors. Running the 1.5.3 binary on Ubuntu (3xHD5870 and HD6310).
Anyone else seeing problems with DEAD GPU that won't recover unless cgminer is restarted?
BB.
Restart dead GPUs does not work for me too. Win7 64bit, Catalyst 11.7 Me too. LinuxCoin beta final In my testing, under Fedora14, SDK2.4, restart GPU works in 100% of my 5xxx series cards, and 0% of my 6xxx series cards. |

Here's what my cooling solution is on the 6U tell me what you think?  imho, Not enough fan speed/pressure for the 2nd set of cards towards the back. |

to be clear, I should be able to boot, and run, from the USB stick this .img unpacks to correct?
tested in offhand machine, Q6600 + 6950, mining never starts, even after "mine restart". Yes I've applied all the fixes.
Not really sure where to look to figure out why..

Long story much shorter, I may be in a position to offer dedicated mining contracts on datacenter based hardware in the next few weeks, if I decide to.
However, given what appears to be the current "scare/sale" among some miners, given current difficulty, blah blah blah, is anyone still interested in mining contracts?
Each box is rack mounted, diskless, running a linux flavor, running either Phoenix, cgminer, or poclbm, monitored 24/7, automated alarms for dropped hashrate, etc. All GPU's are running < 80C.
To simplify, these wouldn't be "coin instead of hash", or "zero variance" but "100% of the results of this hardware, rated at 1000Mhash, are yours for XXX days at $YYY, prepaid for contract length. Tell me where to point it, and you get all earnings" kind of contracts. Given current equipment, I'd be intending to sell in 1000Mhash increments, hopefully 6 and 12 month contracts.
Thoughts? Interest? I know what my costs will be, but suggested pricing for say:
6 month contract, 1000Mhash?
12 month contract, 1000Mhash?
thanks in advance for all feedback. PM me if you'd like to keep the discussion/offer private.

while I can't help with what you should get, I'd avoid that Chenbro. insufficient airflow for quad GPU's (not to mention power connectors on top.)
|
|
|
|
How much MHashes/s can these get?
I'd expect somewhere between 325Mhash and 360Mhash depending on OC, volts, ambient, etc.. YMMV. |

sold several, still have a couple left.. they're beautiful cards.  |

I added support for graphing temperature. There's a link for each worker on the "temp" column which will show you the last 24 hours of temperatures for each card....
How tough would it be to add graphs for both "worker" and "aggregate" mining data, like Mhash, shares, rejects, etc? |
|
|
|
I've created a health monitoring script and a new database table for the Proxy so that you can see your worker "clock speed, mem speed, fan speed, card temperature" from the Proxy Dashboard page. I have the schema change (just an added table) and the health reporting script all finished. Just need to modify the dashboard to support a couple of new columns for that data.
I love what you're doing... that's awesome.. for my 2cents, I'd like to see the temps/load/etc separated from the "worker" name, since multiGPU boxes will generally run (1) worker per box... more than that gets unmanagable quickly. Either that or you poll all the GPU's/CPU/etc in the box, and log the average.. |

First off, love the program, well done, shifted 100% of my miners to cgminer under linux.Feature Request: Can we either get a verbosity level, or a couple of switches for what gets logged to syslog? I like the first part: Jul 24 22:48:45 miner6 cpuminer[26354]: [(30s):304.0 (avg):312.5 Mh/s] [Q:20 A:7 R:0 HW:0 E:35% U:2.00/m]
but don't want the second part in syslog, would rather see that in the "screen" window cgminer is running in. Jul 24 22:48:54 miner6 cpuminer[26354]: Share 437a2419 accepted from GPU 0 thread 2

Jul 24 22:49:06 miner6 cpuminer[26354]: GPU 0 Q:20 A:10 R:0 HW:0 E:50% U:2.86/m
Small nitpick, it's syslogging as "cpuminer" which, in fact.... when you're using GPU, it isn't... either choose the process name under which it syslogs, or being able to set the facility, would help narrow down the logging. Well done, love the program, keep up the good work.

If we went with the cost excluding the 9 extra chassis and including your price cut we have a cost of 2,285. Assuming you get 820 megahash per card thats 1640 megahash.
1640/2285 is .71 megahash per dollar.
An efficient 5830 rig could get 1.36 megahash per dollar so it would cost about 1,205 dollars for the same speed.
having played with the numbers a lot myself, I'm not sure where you get 1.36 MH/$. If you're willing to run open air, and have all your hardware off one motherboard and buy PCI-E extenders, you could run (8-eight) on a single board, but then that decision implies other expenses, like 8 x $25 PCI extenders with power-taps to keep from cooking your motherboard, and framed cases, BIG power supplies, and motherboards that will support 8x PCI-E, all of which add to the bottom line, and offset the savings of the cheap cards. I put the rough build cost on a machine like that at about $2500 by the time you include EVERYTHING you'd need, which is still around $1.07 $/per/mhash for 2400 Mhash. In the example you give of a 1600 Mhash, which, at 300Mhash/per/5830, takes 5+ cards (depending on OC levels), which is still $650-$800 worth of cards, depending on your sources. I'm not saying including the cases isn't hurting the sale, I'm saying that even $1/per/mhash is an aggressive goal.. 6990's have other advantages like Mhash-per-box, but $-per-mhash isn't one of them. |

Will make offer if you can give a reason to trust you. Ebay account or the like.
Click on the little world in my profile, links directly to my ebay profile. Pictures are going to be kinda boring.. it's boxes... but as requested...  Uploaded with ImageShack.us |

No, it's should read either "Ver A.1", "Ver A.2" or "Ver A.3" underneath made in china. A.3 is what I have but I'm looking for a 1 or 2. Thanks I'll look tonight, but I suspect they are A.3, since they're so new. |

Hi, Which version card is this card? Should say in the top right of the label on the bottom of the box. Thanks!  Is "XFX HD-695X-ZNFC" what you're looking for? |
