Title: got problem with 5 x 5870 Post by: fuxianhui888 on June 01, 2012, 12:14:41 AM I tried to run 5 5870 with BAMT,but after couple minutes,BAMT crashed(mouse doesn't move,keyboard doesn't work,stop mining,no network),have to restart again,
anybody has any ideas?

You set your setting up incorrectly.

It's little hard to advise w/o reviewing what you have tried so far, but here are some basic suggestions. I got 5x5850 going on BAMT, but it was pretty unstable at first. You have probably already tried this, but if you have made *any* hardware configuration changes, even if they seem trivial, boot from a fresh copy of BAMT. At one point I swapped one 5850 for another, so the two were in different slots, and BAMT completely freaked out about this. I had to start over with a fresh copy. Also, you might try being uber anal about that fresh copy, as in write zeros to the usb drive to completely wipe it and then use dd in linux as opposed to win32diskimager to copy the image. Another thing to try is to get the cards going manually in phoenix - i.e. cd /opt/miners/phoenix - and start each card manually. If you can get all 5 going this way, this will at least tell you that the problem is specific to the process of starting automatically from the configuration script. Also, try starting your GPUs with *REALLY* moderate settings (like 600/500 core/clock at stock voltage). If they work this way, you know you are pushing the clocks of one or more GPUs too much. If they still don't work, lower the voltage - then if they work you know your PSU can't handle 5 cards at stock voltage.
I think BAMT is awesome, but for me it did a lot of really strange things. I know it's supposed to be essentially plug and play, but in my experience it was a bit less friendly than this. I've switched now to cgminer on a flavor of ubuntu 11.04 (Peppermint Two), and I'm liking this better. I definitely recommend cgminer if you can't get BAMT working.

You are are at 1.05 volts, so you are undervolting, and at that voltage 900 is *really* optimistic. Drop down to 600 to start, and I would also raise your memory clock to at least 450 - I have one 5850 that doesn't like to clock much below that. If you can get all 5 working with these moderate settings, then you can start raising the core/lowering the memory to find out where your cards are getting unstable. If you still can't get all 5 working that way, then try one card at a time by disabling the other four to see if it is just one card giving you trouble. Also, what motherboard are you using? I have read that for some motherboards you have to go into bios and change the latency timer to get 5 cards working. The needed change is to go from 64 --> 96. This didn't seem to matter for my biostar, but I read that gigabyte boards need this setting changed.

Title: Re: got problem with 5 x 5870 Post by: Dargo on June 01, 2012, 01:55:06 AM 850/160 works great on 5870s Probably so, but the OP needs to troubleshoot here, so it would be better to start with something really modest to find out if the issue is the clock settings or something else entirely. I have 6 5850s, and all of them are fine with going to 150 memory setting, except one, which gets unhappy much below 450. So it may be that in general 5870s are fine with 850/160 @1.05 volts, but it doesn't follow that all the OP's 5870s are happy with this.

Title: Re: got problem with 5 x 5870 Post by: rjk on June 01, 2012, 02:04:38 AM Anywhere from 1.125 to 1.175, i.e. stock. If you are undervolting, those probably won't work.

Sorry I don't have rigs running right now so I can't check.still testing if it is stable! thanks for all the suggestions!thanks Add WORKSIZE=128 to your flags. Right now, you are using the default (256), which is probably too large for mem=150. If that doesn't help, go back to mem=300 and try both 128 and 256 as your worksize. You might even try 64 for your worksize - I think some people get best results with that, but 128 is best for me. I also noticed a weird thing with BAMT where mem=250 (and I think worksize 256) gave me a boost in reported hash rate. But as far as I could tell it actually throttled my share submission rate, so I didn't stick with it. Title: Re: got problem with 5 x 5870 Post by: rjk on June 01, 2012, 02:53:06 AM Probably is the worksize. Note that I said 160, not 150. For a negligible power bump, you get a few more hashes with that. That is assuming a core of 850 to 900 or so.

For a negligible power bump, you get a few more hashes with that. That is assuming a core of 850 to 900 or so. +1 for truth. Mind, memory frequencies are approximate. It's hard to explain without rambling, but if you have a bunch of 5830's (different VGA BIOS -may- cause a difference due to possibly different memory latencies coded in. Untested) at a certain core frequency, they should all have a the same "favorite" memory frequency. If you have a 5870 at the same core frequency though, it won't have the same "favorite" as the 5830's as I've found. My 5870's prefer a slightly lower memory at a certain core compared to my 5830's.

I got another problem,I am using powerline ,but after couple hours,the network disconnected, and it won't reconnect,I have to do it manually,anybody has anycode can check the connection and can reconnect automatically? thanks everyone!

With my 5970 if I plug it into the board I can clock the engine to 875 without problems but if I put it on a riser I can only clock it to 850. Higher clocks on risers cause issues for me.

Title: Re: got problem with 5 x 5870 Post by: flatronw on June 15, 2012, 03:13:16 AM I see from your first post that you have 5 Cards (5870's)on one M/board using extenders. Would you please be kind enough to tell me exactly what make and model the M/board is and are the extenders 1 - 16 or 16 - 16 or a combo of the two types. Currently I have two Gigabyte GA-990FXA-UD5 boards that totally refuse to run more than 3 cards (5850), whatever you do or try. They also refuse to reliably boot from USB. They have cost me days and days of "down time" as I fought with them, not to mention the intense frustration!!!. I need to replace them ASAP but need to know which M/board is a 'proven performer" with 4+ cards. Thanks Title: Re: got problem with 5 x 5870 Post by: jjiimm_64 on June 15, 2012, 04:16:04 AM I use 2 mobos..

Did not intend to hi-jack your post. But this is "desperation time" with these GA-990FXA-UD3 boards Thanks for the link to the M/board page, been looking for that for weeks. Mentions GA-990FXA-UD3 but does not clarify which Version. That is what I am starting to think is an issue here. So as not to disrupt this thread anymore I did originally post a question regarding these damn Gigabyte boards in Newbies. So if anybody has any startling revelations regarding making these POS work with more than 3 GPU's please post there. https://bitcointalk.org/index.php?topic=86995.0 Thanks |
