Dude, you brought me out of bitcointalk.org retirement with this post. It was so moving that I actually signed in in order to post this in response. Enjoy!

This one goes out to all my trollies!

Did you change that because the pool boss just showed up?

If I understand correctly, you won't lose your rewards unless the pool comes back up again and everyone except you starts mining. This is because no (or in this case, very few) shares are being submitted. So the pool is kind of on "pause". I may be wrong, so someone please correct me if I am.

What kinda irks me is that some shares are still being submitted which is in fact eroding everyone elses rewards at the moment.


Is it possible to do this at all with phoenix? poclbm was too slow for me and so I stopped using it.  Also, any recommondations on a backup pool? I'd rather backup to a pool that won't let my shares decay after I leave them when Eclipse comes back online. lulz Oh, the hypocrisy!

That's a waste of time and energy that could be used elsewhere in the meantime. The longer my miners sit idle, the potentially longer they may never pay themselves off. They need to be crunching 99.9% of the time 24/7

Is there a method to notify us when the pool is back up again? Or do I have to keep checking the website? I would really prefer to not have my shares decay once the pool comes back up again.

Far as I am concerned, gribble can kiss my ass.  Bitcoin will never become anything if we cant work the nerdiness out of it.

I am Jack and your girlfriend will never let go. Then I will freeze solid and sink to the bottom with all my bitcoins cuz I can barely stay afloat in this command line shit.

I need to do something like this with my 6790s. What would need to be changed to make it happen? I am tired of my mem clocks running so high, and I cant undervolt at all when I use AMDOverdriveCtrl. I followed Inaba's guide for 2.4/64bit for Natty.

Thanks

I have one of those tables already. Though it's not what you see in the last pictures of my stacked racks. It never occured to me though to use one as a rack. I think the legs are way too flimsy, but I suppose installing the 19" components would help add rigidity. Still too high tech for me though - far too classy looking.

I agree with you there and that was one reason I left some supporting material in the back exhaust hole in the first bin. But even when my cards were running in the mid 80s there wasn't a terrible amount of flex and the legs and frame structure held fine. I think making that back exhaust hole helps alleviate that problem anyway since the heat just goes out the back into the open air. The plastic gets thicker the closer to the top you get. All the same, I probably wouldn't stack them more than 4 or 5 high. Staggering the PSUs would probably be a good idea too. As you can see I am no engineer.

That's true, but my lower rig already has 4 cards with no risers and running at a comfortable temp while being overclocked. Just the upper rig doesn't have the other cards installed yet. And I took my pics when making the upper rig. But I was already thinking of something like this for card expansion in case I ever go that route.

Yeah, I am careful about touching my hardware. We don't have any household beasts (if I don't count my wife (..touching hardware...? I'll have to think more on that one)) and I use a antistatic bracelet and do my best to discharge anything that might be on me before tinkering.  It's helped that we've also had decent relative humidity.  I kinda took a few pages out of this book:

And Slush sent me a pic of one of his rigs which is of the same ilk. We live in the same hood and its hard to find test benches or plain motherboard trays here.  I just posted mine because it's much more compact than the veggie boxes we tend to see pics of on this forum.  But isn't it really no different when a case uses plastic standoffs? I have read conflicting info on that subject.


It is. It's been good so far.  My first rig has a 790FX GD70, which I wish i could find more of, because 4 PCIEx16 for 90USD sure was a nice treat.


You should have seen it when I drilled the holes with the motherboard in the bin. Never seen a mobo rattle so much YEE HAW!

This plastic bin, open air case accommodates a minimal setup, i.e USB boot, no hard drive, no CDROM. I have put together two of these so far and they are serving their purpose well.


Materials needed:
                                                         Total Price
(9)   M3x10 pan-head machine screws    0.40USD
(9)   M3x20 standoffs                            2.00USD
(9)   M3 nuts                                        0.50USD
(18) M3 washers                                   0.45USD
(1)   stackable plastic bin                       6.00USD
(16) 180mm length zip strips                 0.60USD

                                                   Total 9.95USD

Tools: scissors, screwdrivers, wrench, cutting/sanding tool (dremel)

Get a stackable ventilated plastic storage bin. The bottom should be big enough to comfortably hold your motherboard and it should be deep and tall enough to accommodate your GPU + fan and allow for some airflow. I saw the one below at my local hardware store and it turned out to be the perfect size.
http://i1113.photobucket.com/albums/k508/crispining/TheBox.jpg


Place the motherboard in the bin. Keep in mind future placement of your ethernet line, USB, GPU hookups, etc and adjust accordingly. Use an indelible pen to mark where you will need to drill your motherboard standoff holes. Remove motherboard and drill your holes.  I used a 3.1mm drill bit to allow for my M3x10 machine screws to fit.
http://i1113.photobucket.com/albums/k508/crispining/PositionMotherboard.jpg


I placed my M3x10 screws with washers on each side from the bottom and loosely secured them with the female end of the standoffs. The male end of the standoffs then protruded up through the motherboard. So this is upside down when compared to a regular computer case setup. It allowed me to place my motherboard in the bin securely, yet temporarily for other steps in my build.
http://i1113.photobucket.com/albums/k508/crispining/StandoffsInstalled.jpg
Carefully check to see if the standoffs properly align with the motherboard standoff holes. If not, it may be possible to adjust them to fit since they are only loosely connected at this point. If they fit fine, then go ahead and fully tighten down the standoffs to the screws. If they are too far off, you may need to find the problem and drill a different hole. Make sure you don't torque your motherboard!!


With the motherboard placed on the standoffs but not yet secured, check the gills of the bin and trim away any gills needed to plug in your ethernet, USB, keyboard and mouse. For my bin, the plastic was soft enough to simply cut with scissors.
http://i1113.photobucket.com/albums/k508/crispining/MakeAccess.jpg


To make the exhaust vent for the GPUs I temporarily placed a GPU in the outer and then inner slots and used an indelible pen for each placement to mark cutting points on the back wall of the bin.
http://i1113.photobucket.com/albums/k508/crispining/MarkCuttingPoints.jpg


I also took the opportunity to mark off the video connection on the front of the bin and cut another ventilation gill with scissors.
http://i1113.photobucket.com/albums/k508/crispining/MarkforGrinding.jpg


I then removed the GPU and the motherboard from the bin and placed them safely away to protect them from flying plastic shrapnel while I cut the hole in the back of the bin with a dremel cutting disk. Cutting really produced a lot of tiny plastic bits that could have caused any number of connection issues with the various components if they had found their way into something.

I used the dremel with a sanding drum to clear away unneeded material from above the ventilation gills to allow for the video output connection to a monitor. After making all the cuts and trimmings I cleaned the dust and debris off of the bin.
http://i1113.photobucket.com/albums/k508/crispining/CutsMade.jpg


I placed the motherboard once again back on the standoffs, this time securing it to the bin with M3 nuts. At this point I added my CPU, RAM and connected the motherboard power cables in preparation for the power supply. (The PSU can be seen already attached in the photo. The next step describes securing it to the bin.)
http://i1113.photobucket.com/albums/k508/crispining/MotherboardInstalled.jpg


With adding the power supply I used 8 180mm zip strips - 4 on each side to make two square straps to hold the PSU to the outside of the bin. Make sure that it is properly fitted to the side to allow enough air flow. In my setup, the intake fan is facing away from the bin and the exhaust is facing to the front. In hindsight, I think 16 zip strips would have been better. (They can still be added with no problem.) That way there would be some redundancy to keep the PSU safe in case one of the ties should break. While making my first setup I had one tie break and the whole PSU broke free. The zip strips fit really nicely through the ventilation gills of the bin. When connecting the power cables to the PSU, take care to support it from the opposite side so that the zip strips don't snap. Also, make sure that any excess from the strips is trimmed away and not interfering with any moving parts of the computer.
http://i1113.photobucket.com/albums/k508/crispining/SecurePSU.jpg


At this point, I added my GPUs and finished making my other connections. Using some extra zip strips. I tied off the power cables to keep them out of the way of airflow where needed. With my first case, since the GPU power cables connected from the top of the card and since there are 4 cards right next to each other, I was able to add a 200mm fan on top of the cards and a 140mm exhaust fan at the back of the bin and I took off the mounting plates (not the plastic shroud) in order to facilitate more airflow for keeping the GPUs cool (pictured below). Also, with my first case, I was concerned about the exhaust hole weakening the structure of the bin too much and so I didn't cut a complete hole. Because of this some exhaust is blocked and one of my cards runs warmer than the others. I am almost certain that if I make the exhaust hole similar to the one pictured earlier in this guide, that card would run about 8C cooler. It may even be possible to remove the exhaust fan entirely to save on noise. As is, I have 4x 6790s OC at 950/850 with temps from ~ 58-74C. In my bin pictured in this guide, I so far have only one GPU and I am awaiting 2 more.

I made the same mistake I think a lot of others made when first getting into mining; I bought an actual case and had issues with overheating cards. I hope this helps save a little money for anyone building a new rig or getting into mining in general. If you feel this was worthwhile to you, please feel free to make a donation. Good luck in your endeavors!

Thanks for your reply. How do I go about upgrading what I have? -both the driver and Phoenix. I followed the 2.4 guide to the letter as of today. I am really quite new to linux and so I have no idea what or where to make an update happen. Could you post some commands for me to follow?


My new system stats:

Mobo: ASRock 970Extreme4
CPU: Sempron 140
RAM 1GB
GPU: 1x Sapphire 5850  
PSU: Corsair AX850

I tried setting up a new system today with a 5850. I used the 2.1 guide for a 64bit system but my CPU went up to 100%. I've read a bit about there being a bug, but it doesnt seem to be affecting everyone. Just because of this, the 2.4 guide is far better. But I have also seen how some have gotten really good results from the 2.1 setup. Does anyone have any suggestions? I have used to search button already and it didn't seem to turn anything up except to upgrade from 2.1 to something else.

Linux noob here.  I am posting a couple questions somewhat related to this thread because of my need for some HOWTO action.

I followed the 64bit edition of this guide and it's working great for my 4 6790s. (I thought I did my homework on those but now I'm kinda stuck with them and would like to get the most out of them.) Anyway, since I am new to Linux, what can I do to make sure I have everything from this guide properly updated? I am not terribly afraid of the command line, but I still don't know enough about it to just start poking around. Is there anything to update at this time? If so, would someone be so kind as to post the couple lines it would take to get the job done?

I have also seen some posts about 6xxx cards not being able to be adjusted a whole lot. In my case, I am running at 950/850 @ 1.19V. Is there any kind of software utility I could install to let me further underclock my RAM and possibly undervolt to save a couple watts and degrees C?  I haven't had much luck looking around online.  I want to maximize efficiency, profit, etc. So I am looking for the sweet spot and would rather not toast my cards too soon. Perhaps I could even sell them at some point.

In case anyone has a setup similar to mine with really specific suggestions to offer, please PM (or post here for others' sake).

My system specs as follows:

Mobo: 790fx gd70
CPU: Sempron 140
RAM 1GB
GPU: 4x Sapphire 6790   950/850/1.19   
PSU: Corsair AX850

Mining at ~860Mhash/s @ 580W
Temps 65-80C depending on card and location on board

./phoenix.py ... -k phatk DEVICE=1 VECTORS BFI_INT WORKSIZE=256 AGGRESSION=13

I know some info here might be extraneous, but I wanted to post it for posterity and just in case...

@Tenobis   Jo, to jsem zjistil asi pred tydnem. Nevim, jak jsem drive nevidel .cz na konci domenu, ale uz jsem clenem.  

Stejne jsem ale n00b a porad neco zmenim, abych mel lepsi Mhash/s/W. Mam zatim 2x Sapphire 6790 s celkem 430Mhash/s, ale cely pocitac cerpa kolem 315W. Pouzivam AMDOverdrivectrl, ale vim, ze neni mozne extremne zmenit paramatery, napr. GPU max. do 950Mhz, pamet nejmene do 850. Volty asi se neda zmenit. Kdyz zkusim, stejne cerpa tolik wattu. Jeste jsem neco cetl v anglictine, ale stale shanim reseni.

Thanks for the feedback. I am still trying to get my head around all the mining info.  I posted my first comment after doing a lot of reading and researching. Then, this morning, I did some more reading and turned some of my conclusions on their heads. Ugh. Actually, the 200USD refers to the CPU, Mobo and RAM. I wanted them to be low cost and energy efficient for mining. Don't we all? The GPU can be a toy for later if I stop mining. Even though, I am just dabbling right now, I also want the GPU to be the best bang for my buck in case I decide to take it further.

To reply to both you and Being, yes, I am hoping to recuperate my costs after about a year. I would love to find a way to do it sooner.

It's been hard finding the sweet spot of high Mhash/s/W with a reasonable investment amount. There are so many variables.  I think I find a GPU I like, then other hardware is more expensive or unavailable. And why don't most people write their results in Mhash/s/W? Who really cares if they are getting 2Ghash/s if its costing them 1Mwatt in electricity?

EDIT: Also, I wanted to get opinions on  the GPU I listed in my earlier post. ASUS MATRIX 5870/2DIS/2GD5

This looks quite a bit different and definitely more expensive than other 5870s I've seen on this forum. For example: XFX ATI Radeon HD 5850 1 GB DDR5 2DVI/HDMI/DisplayPort PCI-Express Video Card HD585XZAFC

I haven't been able to find any mining results on the ASUS card. Any opinions here?

Hey Gang,

I've been looking things over and I am aiming to build a light mining rig with hopes for future expansion. I am a self-professed newb and so I am hoping to get a little help from the community with my choices of hardware. As far as I know, the hardware I have chosen should work together, but if anything sticks out, constructive criticism would be greatly appreciated.

What I have here is a combination of what I found on these two well-known pages:
https://en.bitcoin.it/wiki/Mining_rig and:
https://en.bitcoin.it/wiki/Mining_hardware_comparison#See_Also

Also, I am in Europe and some of the hardware is either unavailable to me or prohibitively expensive.  Links provided go to a Czech website, but I think the specs should still be intelligible even without translation.  Here is the list:

-Mobo: ASUS M4A87TD
    http://www.alza.cz/asus-m4a87td-d198797.htm#popis

-CPU: AMD Sempron 140

-GPU: ASUS MATRIX 5870/2DIS/2GD5
    http://www.alza.cz/asus-matrix-5870-2dis-2gd5-d164659.htm

-RAM: 2x 1024MB DDR3 1333MHz CL9 CORSAIR
    http://www.mironet.cz/2048mb-ddr3-1333mhz-cl9-corsair--xms3-kit-2x1024mb+dp80617/

-PSU: CORSAIR Builder Series CX600 V2 600W , 80 PLUS Certified
    http://www.alza.cz/corsair-cx600-v2-d237950.htmhttp://www.alza.cz/corsair-cx600-v2-d237950.htm

-Chassis: CoolerMaster HAF 912 PLUS black
    http://www.alza.cz/coolermaster-haf-912-plus-cerna-d189911.htm#foto

-Hard Disk: WESTERN DIGITAL Caviar Green 750GB 64MB cache w/ Advanced Format
    http://www.alza.cz/western-digital-caviar-green-750gb-64mb-cache-s-advanced-format-d245784.htm#popis

I know the HDD is quite an overkill on space, but it was one of the cheapest they had that appeared worth anything. My goal is to firstly have a machine that has high Mhash/J, which is more important to me in the long run considering the costs of electricity, and then secondly, to have an initial investment that gives me a high Mhash/$ invested. I figure with the HDD,  I can simply remote access it and use the extra space as storage.

Also, as I am just getting my feet wet, I do not want to immediately invest too much until I get a feel for the practical side of this operation. To that end, I have been planning on building my own PC anyway and so if I decide to bow out of mining, most of the components I plan to buy can be used for my home office/gaming rig. I calculate my bitcoin mining investment portion of this machine to be only about USD 200.

Based on the motherboard I have chosen, would it be possible to add another 1 or 2 of the same GPU if I decide to take this further? I would like to get close to the ~420Mhash/GPU that I have been reading in this thread and so I plan to have the appropriate software and configuration there.


Thanks for any pointers!

Crispin

I want out of here too! I can't stand being all caged up and I can't wait to be released unto this ripe, unsuspecting world. Spam-free, of course. I have lots of questions and comments to make about hardware, and the sooner, the better. I think what I have to say will be better and sooner responded to if I put it in the right place. Sales are ending soon and I wanna do some buying.

I give my humble and solemn word to all on this forum that I will not spam.

Thanks!

Hello all,

I've been lurking here for about a month now and decided to register yesterday. I am looking to help bring more bitcoin awareness to my current location in the Czech Republic.

Ahoj vsichni,

Uz jsem tu asi mesic, a vcera jsem se prihlasil poprve. Chtel bych pomoct, aby vic cechu neco vedeli o bitcoinu. Podle meho nazoru, cim vic po svete vi o bitcoinu, tim lip pro kazdeho.

Zatim, cau.
