cron jobs are the correct solution. time to figure them out.

Can you turn the computer on and off with cron jobs? I don't think it's enough just to stop mining, even idle cards can pull something like 30W.

you can turn it off with cron. back on could be done simply with a setting in the bios to power on @ certain time. that would at least avoid the inevitable filesystem corruption and other issues that stem from simply cutting power to a running linux box over and over.

however, I strongly recommend you *do not* implement a scheme of powering your mining rigs on and off every day.

a vast majority of the USB key wear occurs during boot up. you will accelerate the death of your usb keys tremendously. if you're so worried about power that you can't run a box at idle, you're in the wrong hobby (or the wrong location, at very least).

Make a cron job that does "stop_mining" and "start_mining"

Lodcrappo,

You have any ideas on how to keep from killing the hashrate on 5 & 6 series cards if/when you add 7 series support? Seems like the easiest way would just to do a BAMT split, one with the 2.5 SDK for the older cards, and one with the 2.6 SDK for the 7 series, but everything else under the hood the same.

Or perhaps just a push through the fixer to update the SDK, but with big warning signs to not install it for the 5 & 6 series card users.

I have some ideas, but none that don't result in a lot of work for me. That's why I was not willing to do it unless there was enough donated to at least get a 7 series card myself.

Two images is a pita, thats why I won't do both a 32 and a 64 bit image unless donations fund that work (which is frankly unlikely to happen). It will probably be some sort of optional operation to switch to 7 series. Of course people will want to mix 5,6 with 7 and thats just too bad, its just not possible without sacrificing hashrate.

I am a big fan of BAMT.

I there any way to schedule BAMT mining to run at a specific time of the day? I have 3 rigs (each with 5 5830’s). Each rig draws about 1KW of power. This is a lot of power consumption and I am not sure it is economically profitable to run during “Peak demand” time periods. Fortunately, my power company offers substantial discounts to shift loads to “Off peak”.

Ideally, I would like to power up and mine at night and use minimal power during the day.

I have heard that cron jobs may be a solution but I have not yet figured out how they work.

Any ideas?

Get a plug in timer that can handle the wattage and set the times. (easiest solutions work best)

Tosku,

I thought of that. The only problem is when I power up I have to press a small button on the board to power it. This can be jumpered to the case (I have an open rig...no case) for the power button. I tried to just short out the jumper with the hope of powering up automatically but it powered the board down after a few seconds. The motherboard I am using is a MSI 890FXA-GD70.

Thanks for your idea.

In the BIOS there is an option for what to do when there is a power outage. Change that option to always turn the machine on when power is restored, and then you could use such a timer. The option defaults to always staying off when power is restored.

This might not be the most elegant solution, but it should work:

It really uses minimal power during the off period, something like 1W.

Problem solved, I think. WORKSIZE=128 in the kernel parameters gave a significant bump in speed (from 303 to 352) when running with a single 5850. I'll put the rest of the cards in and report back.

My MSI-GD70 won't work on the USB 3.0.

I use atitweak from the cmd line.

I am really not the best one to ask I do not know linux. I just know what problems I have run into and what I have done to fix them.

BTW LOD Does BAMT support USB 3.0 and having the USB Stick on it?

using atitweak manually is a very good way to explore what your system can and cannot do, or to quickly try various clock rates before committing them to the static config, or to verify settings. if you want to get the most out of bamt, become friendly with atitweak and the other utilities.

as for usb 3.0, all i can say is yes it works fine on the one motherboard I have. if it doesn't work fine, i would just stick the key into a 2.0 slot. there is no benefit to using 3.0 for bamt.

Why not use a 77xx or 78xx card? It's cheaper and works the same way o.o

why not do your job for half the pay? o.O

Buy the cheaper card and keep the rest of the money Cheesy

You might want to actually check you clocks with something other that what bamt says. Just cause it said your mem is at 150 does not mean it is. I had a 6970 that Bamt would say was set like I set it at 1000Mhz but it was actually at 1375. Just my instance but you might want to look into it. I know when I did have a 5850 running on bamt I got 365MHash on BAMT at 920/460mem.

What can I use to check the clocks? Is there something included in BAMT that I can use?

Quote from: lodcrappo on June 11, 2012, 08:10:31 AM

there are several kernel parameters you can adjust in the default miner. probably just need to experiment. you should get similar performance regardless of the miner you use.

What parameters do you think I should adjust? I've tried changing some things around, but I've only gotten worse performance, not better.

I have two 5850 and one 5770 in my BAMT rig at the moment. The performance I'm getting is quite sluggish.
5850 1: 845/150 MHz, 303Mh/s
5850 2: 940/150 MHz, 324Mh/s
5770 1: 930/280 MHz, 215Mh/s

BAMT is using the default miner, phoenix I think. I've set aggression to 11.

I used to get 730 MH/s out of the two 5850 cards alone when they were in my Windows 7 workstation running cgminer, using the same clocks.

What do I need to do to speed things up?

Will using cgminer instead of the default miner make things go faster, or is this a driver/software version issue?
