lodcrappo: Is the failover feature in BAMT supposed to move back to the original pool if it comes back online?

Arsbitcoin.com went down last night for about 1.5 hours and all of my miners switched to my backup pool, which I am very grateful for. Only one phoenix instance out of 50 was mining at ars when I awoke this morning so I am not sure if that one instance never switched over or if it was the only instance which switched back.

It should try to go back to the original after however many shares you set for it.

Link your pools configuration file for the miners (I assume it's the same or very similar). Just blank out any usernames/passwords you need to.

phatk2 gets me 370Mhs/s @ 900/775 with 3 on the board (BFI_INT VECTORS FASTLOOP=false WORKSIZE=128 AGGRESSION=13 -a 5). Still testing with the 5 card rig. How did you get the mem clocks down?

900 has proved very unstable for the cards I am using. I haven't used BAMT to it's full extent yet to fully optimize my Mh/s as stability has been more important since I don't have remote power cycling capabilities yet.

BAMT from USB. Two of these boxes are clocked at 875/500 and one is at 865/500. 875 produces 357Mh/s and 865 is at 354Mh/s.

All 6950's non-ref
--MSI 890FXA-GD70 - 3 on board, very stable. Can't run with even 1 on extender/riser (xorg crash)
--MSI 990FXA-GD65 - exact same CPU, RAM, PS, and cards - 5 working on extenders (still tweaking for stability)

I have three boxes running 5 6950s (non-ref) each with 16x extenders and 1-16x extenders. I use these 2 motherboards:

http://www.newegg.com/Product/Product.aspx?Item=N82E16813157248

I don't have any issues with extender cables or the MBs recognizing the cards.

Are you running BAMT from USB or HDD? And what clocks?

Thanks for the feedback, adding all the reports to the wiki under hardware compatibility list

https://github.com/aaronwolfe/Big-A-Miner-Thing/wiki

lodcrappo you can also add 5 5830s with the same asrock motherboards. Should be able to update you regarding 5970s later this week. Cool

BTW, if u have any free time, could u please help with this ? https://bitcointalksearch.org/topic/cant-overclock-x5-5850-rig-39460 , just reading the first post will be fine.

you are not the first to have similar-ish problems. in the past, it has always come down to something with the hardware... power is common issue. bad risers another. another is just crap cards or motherboard that can't handle the load/timing/something for whatever reason.

best approach is to remove all but one card. seem how it works, how far it can go to stable. then add one, and so one. find out what makes things go down hill.

Could be that my mother is not so good to handle x 5 card overclocked ? because individually the card work fine, together not... and i each riser and its OK.

It's hard to say.. there are two of you having trouble with 5 cards, not sure if both on the exact same MB.

What we know and questions..

Things work fine with 1 card (btw how many cards does it take before things break?)
It's probably something do with the motherboard, I think we've done enough to rule out power or thermal issues
There are some motherboards that working fine with 5 gpus, but don't know what model(s) that is either
Could it even be related to the specific GPU? Like would 5 5830s work, but 5 6950s not? Anyone got a big enough farm and one of these boards with issues that can test stuff like that?

Maybe it would help if people posted the motherboard and GPUs that they have tried and what the results were.. I'll start

MSI 870-G45 - 3 GPUs, works fine with 5830s, 6870s or 6950s
MSI 870A-G54 - 3 GPUs, works fine with 5830s, 6870s or 6950s
Dell SC420 mb (don't laugh) - 2 GPUs, works fine with 5830s, 6870s or 6950s

In my rig, Xorg keeps crashing ( cause 100% CPU usage). Coldreboot does not work sometimes, and if it does, only one of 2 5850s is recognized after a reboot. I had to manualy switch PSU off for abit then turn the system back on.

What might cause such problem? I know its not the GPU or overclocking.

The rig can mine for couple hrs or so b4 Xorg crashed.

This sounds familiar...what MB are you using?

I've had similar issues with my setup. i.e... one card being recognized, CPU pegged etc... Whenever this happens I just re-image te USB and replace the pool and bamt file. It has *always* solved the issue for me.

"I know its not the GPU or overclocking. "

I could say I know it's not BAMT. I have miners running BAMT with 35 days uptime, and have gotten reports of similar stability from plenty of others. What is your reason for thinking it isn't your hardware? I think the most direct approach will be to look at the most likely cause, which given the history of basically every similar issue thats come up in this thread, would be precisely your GPU or overclocking.

Step 1. Remove all overclocking. Does it stop locking up? We need to know this before proceeding.

Its someone else getting this error ?

user@miner:~$ sudo /etc/init.d/mine start
Starting mining processes...: mineYAML Error: Stream does not end with newline character
Code: YAML_PARSE_ERR_NO_FINAL_NEWLINE
Line: 0
Document: 0
at /usr/share/perl5/YAML.pm line 36

You've messed up the formatting in your bamt.conf somehow. Check for weird alignment or other strangeness.
Yaml is picky. Don't honestly know what the formatting rules really are myself, but if you follow the form of the config file that comes with BAMT, you'll do fine.

I made a new fresh install and i just have a x5 5850 mining rig actually mining after 6 or 7 minutes i wrote the pendrive with BAMT. Simply awasome.

Sending 1 BTC to ur wallet, as soon as i have 2 more i will send it too. Thanks!
